Key takeaways

  • MSA is not a completely new concept, it is about doing SOA correct by utilizing modern technology advancements.
  • Microservices only address a small portion of the bigger picture - architects need to look at MSA as an architecture practice and implement it to make it enterprise-ready.
  • Micro is not only about the size, it is primarily about the scope.
  • Integration is a key aspect of MSA that can implement as micro-integrations when applicable.
  • An iterative approach helps an organization to move from its current state to a complete MSA.

Enterprises today contain a mix of services, legacy applications, and data, which are topped by a range of consumer channels, including desktop, web and mobile applications. But too often, there is a disconnect due to the absence of a properly created and systematically governed integration layer, which is required to enable business functions via these consumer channels. The majority of enterprises are battling this challenge by implementing a service-oriented architecture (SOA) where application components provide loosely-coupled services to other components via a communication protocol over a network. Eventually, the intention is to embrace a microservice architecture (MSA) to be more agile and scalable. While not fully ready to adopt an MSA just yet, these organizations are architecting and implementing enterprise application and service platforms that will enable them to progressively move toward an MSA.

In fact, Gartner predicts that by 2017 over 20% of large organizations will deploy self-contained microservices to increase agility and scalability, and it's happening already. MSA is increasingly becoming an important way to deliver efficient functionality. It serves to untangle the complications that arise with the creation services; incorporation of legacy applications and databases; and development of web apps, mobile apps, or any consumer-based applications.

Today, enterprises are moving toward a clean SOA and embracing the concept of an MSA within a SOA. Possibly the biggest draws are the componentization and single function offered by these microservices that make it possible to deploy the component rapidly as well as scale it as needed. It isn't a novel concept though.

For instance, in 2011, a service platform in the healthcare space started a new strategy where whenever it wrote a new service, it would spin up a new application server to support the service deployment. So, it's a practice that came from the DevOps side that created an environment with less dependencies between services and ensured a minimum impact to the rest of the systems in the event of some sort of maintenance. As a result, the services were running over 80 servers. It was, in fact, very basic since there were no proper DevOps tools available as there are today; instead, they were using Shell scripts and Maven-type tools to build servers.

While microservices are important, it's just one aspect of the bigger picture. It's clear that an organization cannot leverage the full benefits of microservices on their own. The inclusion of MSA and incorporation of best practices when designing microservices is key to building an environment that fosters innovation and enables the rapid creation of business capabilities. That's the real value add.

Addressing Implementation Challenges

The generally accepted practice when building your MSA is to focus on how you would scope out a service that provides a single-function rather than the size. The inner architecture typically addresses the implementation of the microservices themselves. The outer architecture covers the platform capabilities that are required to ensure connectivity, flexibility and scalability when developing and deploying your microservices. To this end, enterprise middleware plays a key role when crafting both your inner and outer architectures of the MSA.

First, middleware technology should be DevOps-friendly, contain high-performance functionality, and support key service standards. Moreover, it must support a few design fundamentals, such as an iterative architecture, and be easily pluggable, which in turn will provide rapid application development with continuous release. On top of these, a comprehensive data analytics layer is critical for supporting a design for failure.

The biggest mistake enterprises often make when implementing an MSA is to completely throw away established SOA approaches and replace them with the theory behind microservices. This results in an incomplete architecture and introduces redundancies. The smarter approach is to consider an MSA as a layered system that includes an enterprise service bus (ESB) like functionality to handle all integration-related functions. This will also act as a mediation layer that enables changes to occur at this level, which can then be applied to all relevant microservices. In other words, an ESB or similar mediation engine enables a gradual move toward an MSA by providing the required connectivity to merge legacy data and services into microservices. This approach is also important for incorporating some fundamental rules by launching the microservice first and then exposing it via an API.

Scoping Out and Designing the 'Inner Architecture'

Significantly, the inner architecture needs to be simple, so it can be easily and independently deployable and independently disposable. Disposability is required in the event that the microservice fails or a better service emerges; in either case, there is a requirement for the respective microservice to be easily disposed. The microservice also needs to be well supported by the deployment architecture and the operational environment in which the microservice is built, deployed, and executed. Therefore, it needs to be simple enough to be independently deployable. An ideal example of this would be releasing a new version of the same service to introduce bug fixes, include new features or enhancements to existing features, and to remove deprecated services.

The key requirements of an MSA inner architecture are determined by the framework on which the MSA is built. Throughput, latency, and low resource usage (memory and CPU cycles) are among the key requirements that need to be taken into consideration. A good microservice framework typically will build on lightweight, fast runtime, and modern programming models, such as an annotated meta-configuration that's independent from the core business logic. Additionally, it should offer the ability to secure microservices using desired industry leading security standards, as well as some metrics to monitor the behavior of microservices.

With the inner architecture, the implementation of each microservice is relatively simple compared to the outer architecture. A good service design will ensure that six factors have been considered when scoping out and designing the inner architecture:

First, the microservice should have a single purpose and single responsibility, and the service itself should be delivered as a self-contained unit of deployment that can create multiple instances at the runtime for scale.

Second, the microservice should have the ability to adopt an architecture that's best suited for the capabilities it delivers and one that uses the appropriate technology.

Third, once the monolithic services are broken down into microservices, each microservice or set of microservices should have the ability to be exposed as APIs. However, within the internal implementation, the service could adopt any suitable technology to deliver that respective business capability by implementing the business requirement. To do this, the enterprise may want to consider something like Swagger to define the API specification or API definition of a particular microservice, and the microservice can use this as the point of interaction. This is referred to as an API-first approach in microservice development.

Fourth, with units of deployment, there may be options, such as self-contained deployable artifacts bundled in hypervisor-based images, or container images, which are generally the more popular option.

Fifth, the enterprise needs to leverage analytics to refine the microservice, as well as to provision for recovery in the event the service fails. To this end, the enterprise can incorporate the use of metrics and monitoring to support this evolutionary aspect of the microservice.

Sixth, even though the microservice paradigm itself enables the enterprise to have multiple or polyglot implementations for its microservices, the use of best practices and standards is essential for maintaining consistency and ensuring that the solution follows common enterprise architecture principles. This is not to say that polyglot opportunities should not be completely vetoed; rather they need to be governed when used.

Addressing Platform Capabilities with the 'Outer Architecture'

Once the inner architecture has been set up, architects need to focus on the functionality that makes up the outer architecture of their MSA. A key component of the outer architecture is the introduction of an enterprise service bus (ESB) or similar mediation engine that will aide with the connecting legacy data and services into MSA. A mediation layer will also enable the enterprise to maintain its own standards while others in the ecosystem manage theirs.

The use of a service registry will support dependency management, impact analysis, and discovery of the microservices and APIs. It also will enable streamlining of service/API composition and wire microservices into a service broker or hub. Any MSA should also support the creation of RESTful APIs that will help the enterprise to customize resource models and application logic when developing apps.

By sticking to the basics of designing the API first, implementing the microservice, and then exposing it via the API, the API rather than the microservice becomes consumable. Another common requirement enterprises need to address is securing microservices. In a typical monolithic application, an enterprise would use an underlying repository or user store to populate the required information from the security layer of the old architecture. In an MSA, an enterprise can leverage widely-adopted API security standards, such as OAuth2 and OpenID Connect, to implement a security layer for edge components, including APIs within the MSA.

On top of all these capabilities, what really helps to untangle MSA complexities is the use of an underlying enterprise-class platform that provides rich functionality while managing scalability, availability, and performance. That is because the breaking down of a monolithic application into microservices doesn't necessarily amount to a simplified environment or service. To be sure, at the application level, an enterprise essentially is dealing with several microservices that are far more simple than a single monolithic, complicated application. Yet, the architecture as a whole may not necessarily be less arduous.

In fact, the complexity of an MSA can be even greater given the need to consider the other aspects that come into play when microservices need to talk to each other versus simply making a direct call within a single process. What this essentially means is that the complexity of the system moves to what is referred to as the "outer architecture", which typically consists of an API gateway, service routing, discovery, message channel, and dependency management.

With the inner architecture now extremely simplified--containing only the foundation and execution runtime that would be used to build a microservice--architects will find that the MSA now has a clean services layer. More focus then needs to be directed toward the outer architecture to address the prevailing complexities that have arisen. There are some common pragmatic scenarios that need to be addressed as explained in the diagram below.

The outer architecture will require an API gateway to help it expose business APIs internally and externally. Typically, an API management platform will be used for this aspect of the outer architecture. This is essential for exposing MSA-based services to consumers who are building end-user applications, such as web apps, mobile apps, and IoT solutions.

Once the microservices are in place, there will be some sort of service routing that takes place in which the request that comes via APIs will be routed to the relevant service cluster or service pod. Within microservices themselves, there will be multiple instances to scale based on the load. Therefore, there's a requirement to carry out some form of load balancing as well.

Additionally, there will be dependencies between microservices--for instance, if microservice A has a dependency on microservice B, it will need to invoke microservice B at runtime. A service registry addresses this need by enabling services to discover the endpoints. The service registry will also manage the API and service dependencies as well as other assets, including policies.

Next, the MSA outer architecture needs some messaging channels, which essentially form the layer that enables interactions within services and links the MSA to the legacy world. In addition, this layer helps to build a communication (micro-integration) channel between microservices, and these channels should be lightweight protocols, such as HTTP, MQTT, among others.

When microservices talk to each other, there needs to be some form of authentication and authorization. With monolithic apps, this wasn't necessary because there was a direct in-process call. By contrast, with microservices, these translate to network calls. Finally, diagnostics and monitoring are key aspects that need to be considered to figure out the load type handled by each microservice. This will help the enterprise to scale up microservices separately.

Reviewing MSA Scenarios

To put things into perspective, let's analyze some real scenarios that demonstrate how the inner and outer architecture of an MSA work together. We'll assume an organization has implemented its services using Microsoft Windows Communication Foundation or the Java JEE/J2EE service framework, and developers there are writing new services using a new microservices framework by applying the fundamentals of MSA.

In such a case, the existing services that expose the data and business functionality cannot be ignored. As a result, new microservices will need to communicate with the existing service platforms. In most cases, these existing services will use the standards adhered to by the framework. For instance, old services might use service bindings, such as SOAP over HTTP, Java Message Service (JMS) or IBM MQ, and secured using Kerberos or WS-Security. In this example, messaging channels too will play a big role in protocol conversions, message mediation, and security bridging from the old world to the new MSA.

Another aspect the organization would need to consider is any impact to its scalability efforts in terms of business growth given the prevalent limitations posed by a monolithic application, whereas an MSA is horizontally scalable. Among some obvious limitations are possible errors as it's cumbersome to test new features in a monolithic environment and delays to implement these changes, hampering the need to meet immediate requirements. Another challenge would be supporting this monolithic code base given the absence of a clear owner; in the case of microservices, individual or single functions can be managed on their own and each of these can be expanded as required quickly without impacting other functions.

In conclusion, while microservices offer significant benefits to an organization, adopting an MSA in a phased out or iterative manner may be the best way to move forward to ensure a smooth transition. Key aspects that make MSA the preferred service-oriented approach is clear ownership and the fact that it fosters failure isolation, thereby enabling these owners to make services within their domains more stable and efficient.

Killexams : CBDI Publishes Service Architecture and Engineering Metamodel V2.0

The Everware CBDI Forum published recently the second release of the CBDI Service Architecture and Engineering (SAE) metamodel as part of their SOA reference framework. The metamodel is available free of charge after registration.

Paul Allen, principal consultant at Everware-CBDI, says:

SOA is more than infrastructure, it involves a collection of knowledge and best practices, a coherent conceptual approach, an enterprise blueprint, a reference model, a reference architecture, business process models, a rigorous and standards based approach.

SAE metamodel v2.0 was designed with the input of customers and the feedback they gave on v1.0.

John Dodd, principal consultant at Everware-CBDI, suggests that:

A service architecture needs to be defined at three levels:

  • Specification architecture
  • Implementation architecture
  • Deployment architecture

These views represent the core of the CBDI SAE metamodel. They are supported by other views including: business modeling, organization, policy, service modeling, software modeling and technology.

This week, British technology company Salamander announced that it is launching a new business-driven SOA solution combining its product MooD business architecture technology and the Everware-CBDI methodology. This solution enables full-lifecycle service architecture planning, governance, testing and deployment as a solution to achieving SOA goals.

OPC: Interoperability standard for industrial automation
In today’s complex economy, information is the key to business success and profitability
By Thomas J. Burke

The OPC Foundation is working with consortia and standard development organizations to achieve the goals of superior production with digitalization. The year 2018 has been an interesting, record-breaking year, with end users, system integrators, and suppliers focused on maximizing their engineering investments and increasing productivity. End users are capitalizing on the data and information explosion. Consortia and standard development organizations (SDOs) are helping suppliers to exceed expectations.

Integration opportunity

Information integration requires standards organizations to work together for interoperability with synergistic opportunities to address convergence and to prevent overlapping complex information model architectures. The standards organizations have been working independently, and now it is time for them work to together to harmonize their data models with other standard organizations. The criteria for success for an SDO should be measured by the level of open interoperability provided.

When OPC UA was first conceived, it focused on developing a strategy for platform independence and a solution that allowed the operational technology (OT) and information technology (IT) worlds to communicate, have seamless interoperability, and be able to agree on syntactical and semantic data exchange formats.

The OPC Foundation started developing a service-oriented architecture, recognizing the opportunity to separate the services from the data. It consciously developed a rich, complex information model that allowed the OPC data to be modeled from the OPC classic specifications.

OPC Foundation

The mission of the OPC Foundation is to manage a global organization in which users, vendors, and consortia collaborate to create standards for multivendor, multiplatform, secure, and reliable information integration interoperability in industrial automation and beyond. To support this mission, the OPC Foundation creates and maintains specifications, ensures compliance with OPC specifications via certification testing, and collaborates with standards organizations.

OPC technologies were created to allow information to be easily and securely exchanged between diverse platforms from multiple vendors and to allow seamless integration of those platforms without costly, time-consuming software development. This frees engineering resources to do the more important work of running the business. Today, there are more than 4,200 suppliers who have created more than 35,000 different OPC products used in more than 17 million applications. The estimate of the savings in engineering resources alone is in the billions of dollars. The OPC Foundation strategy is:

  • rules for OPC UA Companion Specifications developed together with partners
  • predefined process for joint OPC UA companion specifications
  • templates to ensure standardized format and potential certifications
  • compliance
  • intellectual property
  • working processes

The OPC Foundation is focused on evangelizing the OPC UA information framework and collaborating with standards organizations and consortia to incorporate data models that reflect the knowledge of their subject-matter experts.

Information models

OPC UA, beyond being a secure, interoperable standard for moving data and information from the embedded world to the cloud, is an open architecture for a wide range of application information models that add meaning and context to data. Information modeling allows organizations to plug their complex information models into OPC UA. This brings information integration and interoperability across disparate devices and applications. Using the common OPC UA framework was a way for all standards organizations to seamlessly connect their data between the IT and OT worlds. This greatly simplifies the end user's task of digitalization.

Service-oriented collaborative architecture

The OPC Foundation collaboration across many organizations is a very important part of the OPC UA service-oriented architecture that lets other organizations model their data and have it seamlessly and securely connected. The concept is simple. An organization develops its data model, mapping it to an OPC UA information model. Vendors can build a server that publishes information, providing the appropriate context, syntax, and semantics. Client applications or subscribers can discover and understand the syntax and semantics of the data model from the respective organizations. An OPC UA server is a data engine that gathers information and presents it in ways that are useful to various types of OPC UA client devices. Devices could be located on the factory floor, like a human-machine interface, proprietary control program, historian database, dashboard, or sophisticated analytics program that might be in an enterprise server or in the cloud.

The initial collaboration that the OPC Foundation engaged with was called OpenO&M, which was a cooperation between OPC Foundation, MIMOSA, ISA95, and OAGIS. This first collaboration resulted in several OPC UA companion specifications that were focused at the IT world and integration with the factory floor. The graphic shows the logos of the numerous standards organizations that the OPC Foundation has partnered with. These specifications allow generic applications to connect to different devices and applications to discover and consume the data and information.

Fast forward to late 2018, and the OPC Foundation has now partnered with more than 40 different standards organizations. These organizations include every major fieldbus organization, robotics, machine tools, pharmaceutical, industrial kitchens, oil and gas, water treatment, manufacturing, automotive, building automation, and more. All of these organizations are now developing or have already released OPC UA companion specifications, and these organizations can take advantage of the service-oriented architecture of OPC UA.

Some of the more important consortia that are predominantly end-user driven include the oil and gas industry, pharmaceutical NAMUR, and VDMA (the Mechanical Engineering Industry Association). There is also a lot of energy being "energized" in the energy industry (no pun intended). There are exciting trade shows in the machine tool industry and the packaging industry. Significantly, suppliers and end users are realizing the volume of data from all the devices and applications that needs to be turned into useful information.

One of the most exciting organizations that the OPC foundation has collaborated with is VDMA, representing more than 3,200 companies in the subject-matter-expert dominated mechanical and systems engineering industry in Germany and the rest of Europe. It represents the breadth of the manufacturing industry developing and leveraging standards across multiple industries.

The OPC Foundation activities include collaborations with a number of industries and applications, including automotive, building automation, energy, oil and gas, robotics, welding, pharmaceutical serialization, transportation, machine tools, product life-cycle management.


Governments and regulatory agencies are now becoming actively engaged in the standard-setting process. Industrie 4.0 started in Germany and has spawned a number of regional equivalents throughout the world that are accelerating standards development and adoption for complete system-wide interoperability. Examples include Industry 4.0 concepts being adopted in countries with various initiatives that include Made in China 2025, Japan Industrial Value Chain Initiative (IVI), Make in India, and Indonesia 4.0. Clearly there is a future for the holistic automation, business information, and manufacturing execution architecture to Boost industry with the integration of all aspects of production and commerce across company boundaries for greater efficiency.

A lot is happening in the world of open standards. The OPC Foundation is tightly engaged in collaboration with a multitude of organizations and is reaching across to other verticals beyond the domain of industrial automation.

Vertical integration

The whole concept of IT and OT convergence is very important to the suppliers and even more important to the end users, because they want a strategy and a vertical integration from the plant floor (sometimes called the shop floor) to the top floor or enterprise. What is most important in this equation of vertical integration of data from the plant floor's variety of field devices can be consumed and then turned into useful information as it goes up the food chain to the enterprise. Essentially, data becomes information as it is converted in the different layers of the vertical integration architecture.

Integration is bidirectional between sensors and controllers and the enterprise/cloud, communicating all types of information, including control parameters, set points, operating parameters, real-time sensor data, asset information, real-time tracking, and device configurations. This architecture creates the basis for digitalization with intelligent command-and-control to Boost productivity, drive make-to-order manufacturing, Boost customer responsiveness, and achieve agile manufacturing and profits.

OPC collaboration process

The OPC Foundation strategy is pretty simple. It has an established set of processes, so organizations can work together to develop OPC UA companion specifications complete with templates for the standardized format of the data to be understood and consumed generically. It establishes working groups and protects the intellectual property. All of the companion specifications become open standards to facilitate the whole vision of success measured by the level of adoption of the technology.

The OPC Foundation also has the certification program, which allows the companion specifications to be certified for interoperability.


The industrial and process manufacturing industries have realized they can Boost production by using data to gain insights and to optimize. This is leading to the movement toward digital manufacturing, which is the syllabu of many new conferences all over the world on big data, machine learning, artificial intelligence, Industrial Internet of Things (IIoT), IoT, cloud computing, edge computing, and the fog. End users and suppliers are overwhelmed with all these new innovations and are sorting out what makes sense to leverage from a business value perspective to maximize their effectiveness in daily production operations. Collaboration between the OPC Foundation and a wide range of other industry organizations is bringing clarity.

Killexams : Harriet Harriss to transition out of deanship role at Pratt School of Architecture

Pratt Institute Provost Donna Heiland has shared news that Harriet Harriss, dean of the Pratt School of Architecture (SoA), will transition out of that role—one she has held since 2019— to pursue independent research beginning this fall. Per an email sent to the Pratt community announcing the major departure, Harriss will join the SoA as faculty when her research concludes, remaining a part of the Pratt family. “This transition will allow her to focus on advancing her expertise in the intersection of climate justice pedagogy, practice and policy, in service to the School’s strategic agenda and strength in this area,” wrote Heiland in her letter.

Quilian Riano, who joined the SoA last year in the role of assistant dean, will serve as interim dean during the transition process. A search for a new dean of the Brooklyn-based school will commence in the coming academic year.

British-born Harriss has been a close friend and ally of The Architect’s Newspaper throughout her tenure at Pratt and was a fierce advocate of the New Voices in Architectural Journalism fellowship program, a joint initiative launched in early 2021 by AN and the SoA. (A second round of contributions from the inaugural New Voices fellows will be published in the forthcoming July/August issue of The Architect’s Newspaper).

Prior to joining Pratt in 2019, Harriss led the Post-Graduate Research Program in Architecture and Interior Design at the Royal College of Art in London; before that, she helmed the Masters in Applied Design in Architecture program at Oxford Brookes (formerly Oxford Polytechnic). She replaced longtime SoA dean Thomas Hanrahan following his 22-year tenure.

Harriss’s deanship at the SOA was one marked by the sweeping societal upheaval brought on by political unrest and a global pandemic along with a historic social justice movement spurred by shocking acts of violence perpetrated against Black Americans. Despite the challenges presented by the COVID-19 crisis, Harriss’s accomplishments as dean were myriad. They include: the foundation of the school’s first Diversity, Equity, and Inclusion (DEI) Council, the establishment of a graduate incubator, the launch of a master’s degree in landscape architecture, and the creation of the new, two-person role of student advisor to the dean. In 2021, the SoA became the first American school of architecture to hold international accreditations from both NAAB and RIBA. Additionally, Harriss also increased the number of annual student prizes as a means of bettering showcase the talents of the SoA community.

“Seeking to advance faculty, she has helped faculty to establish and/or nurture partnerships with museums, cultural organizations, practices and community groups, and started a faculty fellowship program,” wrote Heiland of her colleague. “She has advanced both the work and the profile of the School as a whole, hosting international conferences as well as a number of symposia, recruiting highly esteemed visiting fellows, and raising the School’s international visibility through its online presence as well as its widely circulated newsletter.”

AN applauds Harriss for her transformative tenure at Pratt and wishes her the best on her upcoming ventures.

The University of Muenster has been developing the Real-Time Framework (RTF), a novel middleware technology for a high-level development of scalable real-time online services through a variety of parallelization and distribution techniques. RTF is implemented as a cross-platform C++ library and embedded into the service-oriented architecture of the edutain@grid project (FP6) and the software-defined networking architecture of the OFERTIE project (FP7) . It enables real-time services to adapt themselves during runtime to an increased/decreased user demand and preserve QoS by adding resources transparently for the users. The integrated monitoring and controlling facilities offer an open interface for the runtime resource management of ROIA services.

Detailed Information

More detailed information about the RTF and the edutain@grid project can be found under:


The RTF will revolutionize the development of real-time, highly interactive Internet application services. In particular, following novel features are supported:

  • High-level development of scalable real-time interactive applications.
  • Scaling interactive real-time applications like online games through a variety of parallelization and distribution techniques.
  • Monitoring and controlling of real-time applications in service-oriented architectures.
  • Seamless experience for services running on multiple resources.
  • Service adaptation during runtime to a changing user demand.
  • Preserving QoS by adding resources transparently for consumers.
  • Integrated mechanisms for trust and security (authentication, encryption, etc.).

Added Value for Application Developer

Edutain@Grid provides the Real-Time Framework (RTF) to application developers as a C++ library to efficiently design the network and application distribution aspects within the ROIA development. RTF's integrated services enable developers to create ROIA on a high level of abstraction which hides the distributed and dynamic nature of applications, as well as the resource management and deployment aspects of the underlying infrastructure (Grid). The high level of abstraction allows RTF to redistribute ROIA during runtime and transparently monitor their real-time metrics.

RTF provides to the application developer:

  • An automated serialization mechanism, which liberates the developer from the details of network programming.
  • A highly efficient communication protocol implementation over TCP/UDP optimized with respect to the low-latency and low-overhead requirements of ROIA. This implementation is able to transparently redirect communication endpoints to a new resource, if, e.g., parts of the ROIA are relocated to a new grid resource for load-balancing reasons.
  • A single API for using different parallelization approaches: zoning, instancing, replication and their combinations, for a scalable multi-server implementation of ROIA.
  • A fully automated distribution management, synchronization and parallelization of the ROIA update processing.
  • A transparent monitoring of common ROIA metrics that is used by the management and business layer of the edutain@grid system.

Added Value for End-User

  • The use of RTF makes the distribution of the application over multiple servers transparent for the users, e.g., online gamers and participants of e-learning simulations.
  • Security is guaranteed by the authentication and encryption of communication connection.
  • RTF tolerates the use of non-encrypted and non-reliable communication protocols.

Killexams : Could remote working from home become a legal right?

By Amanda Kavanagh

Working from home (WFH) is the most polarising issue in the workplace right now.

Since last summer, when many organisations began the switch back to staggered in-house working, there has been a disconnect between executives and employees.

Those companies who went hard on returning to the office, like Google, Tesla and Apple, saw firm pushback from employees who realised they quite liked not having the stress and expense of a commute.

They had more time for their family, friends, pets and hobbies, and they’d shown they could do their job remotely during the pandemic’s peak, so why not now?

As companies around the world muddle through making hybrid working practices work, the Netherlands is aiming to enshrine remote working flexibility in law.

If implemented, the new law will force employees to consider employees requests to work remotely, as long as their profession allows it. It follows in the wake of a 2020 Royal Decree-Law implemented in Spain that protects workers’ rights to work remotely.

The Dutch legislation was already approved by parliament and it now needs to be rubber stamped by its Senate before it is adopted.

Many remote workers are optimistic, as even before the pandemic in 2018, 14 per cent of employed people usually worked from home, the highest per cent in all EU member states, according to Eurostat.

The Dutch government has encouraged businesses to continue WFH during the pandemic, and starting this year, implemented a reimbursement programme for businesses which incurred additional costs to facilitate remote working for their employees.

It’s a sign of the times, particularly when you look across the Atlantic where a recent McKinsey study of 25,000 Americans, found that 87 per cent of workers with the option of hybrid or WFH were willing to take it.

Amid talent shortages across multiple industries, taking a remote-positive stance broadens a company’s talent pool horizons to a global network.

However, facilitating remote working does come with its own challenges if hiring from multiple countries, such as adhering to employment, tax and intellectual property laws in each state or country, facilitating asynchronous working in different timezones and additional HR resources to ensure employees settle in.

For this reason, many jobs are advertised as remote but within a particular state or country, while other companies are willing to put the effort in to hire from anywhere.

There’s a mix of remote options on the Euronews Job Board, which is regularly updated with remote working opportunities available across Europe.

Here are three hot remote jobs on offer right now.
