Killexams : Building Microservice Infrastructure with Cisco's Mantl 1.0

At Cisco Live 2016, held in Berlin, the latest version of Cisco’s open source microservice platform, Mantl, was released. New features in this 1.0. release include multi-data center configuration via tooling like Project Calico, simplified version control of a developer's entire infrastructure configuration, and blue/green testing as part of a service upgrade process.

InfoQ sat down with Ken Owens, CTO of Cisco Intercloud Services, and asked about the use cases, design decisions and future plans associated with this latest release of Mantl. 

InfoQ: Hi Ken, thanks for taking the time to talk to InfoQ today. Could you briefly explain what Mantl is please?

Owens: Mantl provides all the infrastructure components you need to deploy your microservices platform. We have chosen industry standard components, such as Docker, Mesos and Terraform, and made them work well together, so you don't have to write any glue code.

Mantl automates tasks that used to require months of DevOps time to do, that way your can focus on your application and not your infrastructure. Our vision is to enable you to focus on the application code and business agility, not infrastructure APIs.

The Mantl framework is able to provision both infrastructure and software as code. This allows users to deploy their services and applications in a programmable, repeatable manner. Mantl is also cloud agnostic - it can deploy to a range of cloud providers: Rackspace, AWS, DigitalOcean, Google Cloud Platform, etc. Alternatively, private clouds can be provisioned: OpenStack, VMWare, bare metal or any set of systems running CentOS.

We also plan to build a community around providing an end-to-end solution for microservice infrastructure, not around an individual component, designed to solve business and team challenges, one platform, improved by the community and tested everywhere.

InfoQ: You're talking at Cisco Live 2016, held in Berlin, about the launch of a new version of Mantl. How has Mantl changed since InfoQ last published details about the project?

Owens: Quite a lot has changed. Here are the highlights:

  • Multi-data center configurations are supported using a WAN and tools like Project Calico.
  • Many services are available to use out of the box (with more being added daily): software defined networks, software defined storage, DNS support, databases, monitoring tools, service discovery (Consul), secret storage (Vault), logging (ELK stack), security, etc..
  • The user’s entire project stack, from infrastructure to application configuration, can be placed under version control.
  • The Mantl project is automatically tested against a range of cloud providers to ensure quality.
  • Since Mantl 0.6, it is possible to perform blue/green testing as a part of the upgrade process.

InfoQ: Could you explain the typical uses cases that Mantl is appropriate for, and also explain why a developer or architect should choose this project as their infrastructure platform?

Owens: Typical use cases fall into cloud native (Gartner’s ‘mode 2’), data analytics, and transform. Some of the most important components include Mesos, Marathon, Docker and Consul. Mesos is the backbone of Mantl. It places a layer of abstraction on resources (cpu, ram, ports, etc.) and is able to allocate work over a cluster of machines. Marathon is a simple orchestration tool to start microservices.

A service definition would specify the resources required which is then submitted to Mesos for allocation, via Marathon. Marathon then ensures that the service is healthy and restarts the service if it ever fails. Consul is a service discovery mechanism. Mesos tasks are automatically given a Consul endpoint based upon their name, for service discovery. So to connect to zookeeper, for example, it is as simple as addressing zookeeper.service.consul.

The most important configuration file is the Ansible playbook. This defines what will and will not be installed at a high level. For example, there is that code defines the software that is installed on a host that has been defined with the role of “control”. On all of the nodes with the role of control, they will also be given the roles of Vault, ZooKeeper, Mesos, Marathon, Chronos and mantl-ui. These refer to the components that are going to be installed, which are defined elsewhere in the project.

We believe that the architecture of Mantl addresses the next evolution of application development automation is a microservices model.

InfoQ: Many developers and organisations are evaluating the use of Kubernetes, stating that operational effort required for deploying Mesos-powered platforms only has a justifiable ROI for large-scale deployments (i.e. Twitter and Apple). What are your thoughts on this?

Owens: Great question. Choice and extensibility are the key elements of any true transformational model. Mesos has a framework approach which have been very useful for several of our enterprise customers. Kubernetes has some definite performance and scale benefits that we have tested.

One of the values of Mantl is that we handle all these operations aspects in the platform and support large-scale deployments. However, if you’re interested in Kubernates, we have integrated Kubernates into the Mantl platform and will have a release in about 1 month with the initial support. For more information you can check out our github repo.

InfoQ: Are you planning to offer any support model or SLAs for users of the Mantl?

Owens: Yes, we plan to offer a support model for Mantl as well as an enterprise grade model in addition to the open source model.

InfoQ: Could you offer any insight into how components of Mantl are chosen, e.g. the HashiCorp Terraform, Logstash etc. Is there an evaluation process, or do you simply chose 'best of breed' technology?

Owens: We follow a service design methodology. The first aspect is sensing the large shifts in this technology space and defining an architecture for mode 1 to mode 2+ methodologies. Once we had the architecture we asked for feedback from our enterprise developer and SP partners while we looked at the different open source projects that were most popular.

Open source is a big part of the culture we have at Cisco. Once we have the feedback and software options in mind, we created a prototype of Mantl in a project called 'Microservices Infrastructure'.  This involves lots of testing, optimizing, evaluating, and scale testing aspects.

As we went into the Service Design phase, we looked at the gaps in today’s tools and what the architecture required and we approached those in the project. This includes networking (IP per container/group of containers), services discovery, service availability, security, and application policy. In the end, we had Mantl which address the architectural needs, “best of breed” technology, and customer feedback.

InfoQ: Can we ask for your predictions in the container/orchestration space over the next year, particularly in relation to the enterprise space? Will Docker be fully embraced? Will another viable container format emerge? How will the traditional IT infrastructure vendors deal with the changing landscape and emergence of platforms like Mantl etc?

Owens: The industry is in the middle of another transformation towards microservice infrastructures. The hype around this is higher than any technological transformation I have ever been involved in. I’m not convinced that we will have a winner in the next year. I believe the adoption rate will grow but the complexity of a single container vendor and ecosystem will have the enterprise looking at converged solutions like Mantl.

InfoQ: Thanks for you time today Ken. Is there anything else you would like to share with us?

Owens: We look at this as a community effort and invite your readers to get involved. Please check out Mantl at http://mantl.io and follow us on Twitter at @usemantl.

Additional information on the Mantl project can be found on the framework’s website, and also within the associated GitHub repository.

Killexams : Cisco Is Conquering the Climate and Recycling Goals It Has Set. How?

CiscoCisco Systems develops, manufactures, and sells networking and telecommunications equipment — hardware and software. It is best known for creating the software to allow companies to store their information in the cloud — the Internet of Things, which gives critical employees visibility into the entire operations. It is also well-known for domain security, artificial intelligence, videoconferencing, and energy management, generating $49 billion in revenues last year with 80,000 employees. 

“Our technology can also be used to help the world prepare for the consequences of a changing world and a changing climate — such as to monitor grid reliability, enable grid decarbonization, monitor transportation and water systems, and support the workplace of the future,” Cisco says. “Now we are helping them adapt to a low-carbon circular economy as well.” 

Cisco’s quest to be environmentally sustainable started in earnest in 2008. Now it is committed to reaching net zero across all emissions — internal and external — by 2040, including our product use, operations, and supply chain. Cisco’s net-zero goal will be supported by ambitious near-term targets, including reaching net zero for all global Scope 1 and Scope 2 emissions by 2025.

The strategies it will use to hit net zero by 2040 include: 

  • Continuing to increase the energy efficiency of our products through innovative product design;
  • Accelerating the use of renewable energy;
  • Embracing hybrid work;
  • Investing in carbon removal solutions, and
  • Further embedding sustainability and circular economy principles across our business. 

Are you hitting your climate goals? 

  • Cisco’s current goal is to reduce Scope 1 and 2 emissions by 60% in 2022, compared to 2007. 
  • Cisco has achieved 100% renewable energy in several countries around the world and is on track to reach its goal to use electricity generated from renewable sources for at least 85% of Cisco’s global electricity this year. 
  • Cisco avoided 1 million metric tonnes of CO2 equivalents in its supply chain through a range of actions — such as utilizing more ocean shipments, redesigning product packaging, and implementing energy management partnerships. It then set a new goal to reduce supply chain-related greenhouse gas emissions by 30% before 2030, using 2019 as a baseline. (Those are called Scope 3 emissions.) 
  • Cisco is committed to “designing and managing its products and packaging for reuse, repair and resource efficiency.” It is on track to create products and packaging that comply with Circular Design Principles by 2025.

“Cisco had also been promoting Green IT in its business by launching various initiatives to reduce their carbon footprint from their data centers to offices and cafeterias,” writes icmrindia.org. “The same initiatives were being used to help Cisco customers … The energy-efficient cloud solutions of Cisco helped businesses to reduce their IT energy needs.”

What are some of your energy management tools?

Cisco’s intelligent building solutions reduce energy consumption — a technology it uses for itself and its customers. The technology uses low-voltage power over the ethernet to provide network-based monitoring and control of temperature, air quality, and lighting. It points to  ASHRAE, which creates building standards. It has a new building that uses those tools to optimize its HVAC programs based on occupancy. It combines with its onsite solar PV system, enabling the facility to consume less energy than it generates. 

The company also makes the technologies to Boost grid operations, allowing the wires to run more efficiently. That is, its tools can make room for green electrons. They can also redirect traffic on the grid if there is congestion. Enel, an Italian utility, uses these tools to address any faults or failures that threaten the electric network. It also helps the utility deploy more wind and solar energy. 

And the circular economy?

Cisco works with customers, cities, and other organizations to expedite the move to the circular economy — the reuse and recycling of materials to prevent them from going to the landfill. Intesa Sanpaolo, a major European bank, is one such customer. It has financed more than 200 circular economy projects. “Intesa Sanpaolo and Cisco began working in partnership to provide wrap-around support, from financing to technology, for companies going into a circular transition.”

Cisco also partnered with  99Bridges to create a reusable bag system; it eliminates single-use plastic bags. The two developed a platform to remind and reward customers not to discard their plastic bags. The software they call Mosaic provides retailers the tools to track these plastic bags. 99Bridges is working with top retailers like Walmart, Target, and CVS. 

Tell us about your water stewardship?

Cisco’s primary use of fresh water is in its operations — the ones used for restrooms and onsite restaurants. It also uses water for its cooling towers and irrigation. It uses recycled water to water its landscape. It says that its headquarters in San Jose are no longer water-stressed. “This is because, in 2019, the WRI Aqueduct Tool updated its baseline water stress for the California Coyote River Basin, in which our headquarters are located, from Extremely High (>80%) to Low (<10%).”

The company’s water strategy is to benchmark and report water use and risks based on best practices. It also conserves water — especially in water-scarce areas such as India. To that end, Cisco uses a water management system in Bangalore, India, which has a zero-discharge facility. That means no wastewater is discharged into the environment. The wastewater is sent to two sewage treatment plants using filtration and “reverse osmosis,” enabling reuse of the water. 

Much of the focus going forward will be on the nexus between energy and water. It points out that the US Geological Survey estimates that it takes 15 gallons of water to generate 1 kilowatt-hour of electricity in this country. “We estimate our fiscal 2021 energy reduction projects, which avoided 6.6 GWh of energy usage, also avoided 374 cubic meters (m3) of water—roughly 13 percent of our total fiscal 2021 water use.”

Killexams : Best Enterprise Gear for the 802.11ac Wi-Fi Standard
  • Beamforming (typically transmit)
  • Multi-User Multiple Input Multiple Out (MU-MIMO), introduced with Wave 2
  • Multi-gigabit backhaul
  • Wireless intrusion protection
  • Antenna options

Another very important thing to look for that differentiates each vendor’s individual product lines is their support for spectrum analysis, noise reduction and channel management. What To Look For In 802.11ac Access Points

Let’s take a closer look at some of the features you’ll find in 802.11ac enterprise gear.

Beamforming

All of the WiFi vendors mentioned in the product comparison on page two support some form of beamforming. So what is beamforming? Well at a high level, Beamforming allows the transmitter and MIMO receiver to work together to achieve the best signal possible by using multiple antennas to transmit and receive signals. This is done in order to effectively increase the signal strength by attempting to prevent signals from cancelling each other out at the receiver. This is accomplished through a number of different technical methods, the most simple (relatively) being the alteration of the signal gain and phase. Bi-directional beamforming takes this idea and optimizes it by having both the access points (AP) and the client support beamforming, this way the signal is not only being optimized from the AP to the client, but also from the client to the AP. However, some major wireless vendors have yet to implement it.

As with everything in business, the actual results that are provided by a given vendor’s solution can differ significantly from what they promise. Make sure to take the time to test multiple vendors’ products in the target environment to ensure the expected performance is achieved.

MU-MIMO (New In Wave 2)

One of the biggest positive changes that came with Wave 2 supported devices is in their support for Multi-User Multiple Input Multiple Out (MU-MIMO). While Wave 1 devices supported Single User MIMO (SU-MIMO), so have many 802.11n devices for some time. The big change is the support for multiple conversations between different wireless clients at the same time. With SU-MIMO, the AP has to communicate with one device at a time (for very short amounts of time). With MU-MIMO, the AP can now simultaneously communicate with multiple devices, which greatly increases the usability of the wireless network. 

Multi-Gigabit Backhaul

One of the common issues for existing wireless deployments is that APs have been typically deployed using Power over Ethernet (PoE) using a single copper cable for backhaul. With earlier wireless implementations this wasn’t a problem because the aggregate wireless throughput was always lower than the physical capabilities of that single cable. However, with the implementation of 802.11ac Wave 2 devices this is no longer true. There are a few different solutions for this including NBASE-T and MGBASE-T. Both offer solutions that allow existing cabling (copper cables that don’t support 10 Gigabit Ethernet) to stay where they are and now support rates of 2.5 or 5 Gbps, allowing companies to upgrade their wireless infrastructure without needing to upgrade their cabling infrastructure. 

Another option may exist for certain deployments where multiple cables exist for each AP. In this case, it may be possible for a link aggregation solution to work to combine the throughput of multiple links. In these situations look for products that support IEEE 802.3ad (LACP).

However, keep in mind that this is an issue that will only exist for specific environments (high density). Inspect your environment to make sure that this is truly a problem before using it as a selection criteria.

Wireless Intrusion Protection

As with every other piece of networking equipment, security is very important. Most vendors support some type of wireless intrusion protection, typically including detection of rogue access points and clients. While this may be an add-on to some vendor’s product lines, it should be a consideration in your 802.11ac product selection. Antenna Options

In the world of wireless, one thing that can never be overlooked is the selection of available antennas for a specific product. Since the environment that a wireless network must work within is almost always different, the ability to adapt a solution to use multiple types of antennas to achieve good performance is vital.

Spectrum Analysis, Noise Reduction And Channel Management

Anyone who has ever implemented a wireless network is familiar with what noise can do to the availability and capability of a wireless network (is the microwave running?). Most of the vendors have their own features that are intended to reduce both the noise created by their solutions and external noise that affects their solutions. This is done through a combination of both active and passive noise environment detection. Based on the results from this added information, the signal can be modified to best meet the requirements of a specific environment. Most of the 802.11ac solutions we list on page two support the ability to dynamically change the channel being used by each radio depending on this learned information. Some even offer the ability for a dual band radio to change from 2.4 to 5 or vice versa depending on the wireless demand and the current environmental conditions.

The next two steps coming to the wireless evolution are: the full implementation of the 802.11ac standard (also referenced in some places as Wave 3) and the eventual next standard 802.11ax.

802.11ac Full Implementation (Wave 3)

802.11ac Wave 3 is not the official name, but it is a familiar moniker that is used to talk about the full implementation of the 802.11ac standard. The implementation of Wave 2 comes up short against the specifications of the full implementation. The full implementation offers support for a maximum physical rate of around 6.9 Gbps (with a single radio) using 160 Mhz channels (or 80-80 Mhz non-contiguous channels), 256 QAM and 8 spacial streams.

Note: a physical line rate of 6.9 Gbps works out to about 4.5 Gbps of MAC throughput

802.11ax

The next version of the 802.11 standard is going to be 802.11ax. The standard is now in the process of being developed as this article is being written. Some of the things to look for are 10 Gbps wireless speeds, standard support for 1024 QAM (which is already supported in some consumer devices) and possibly (multi-user) multiple input, multiple output-orthogonal frequency division multiplexing (MIMO-OFDM). What else is in store for 802.11ax? We’ll keep an eye out for it and will update this article as more information is made available. Now let’s take a closer look at some of the top 802.11ac access points and how they compare.

Killexams : Symbio, Cisco partner to launch Webex Calling solution in Singapore

Australian-listed voice communications software provider Symbio has announced the launch of a unified communications solution for Cisco’s Cloud Connect for Webex Calling which will be available to Cisco resellers and their customers in Singapore.

Symbio (ASX:SYM) says that in a first for the Singapore telecommunications market, the capabilities will enable Cisco resellers to deliver a simple, cost-effective cloud communications solution for Webex Calling, enabling end users to make calls locally and globally via Symbio’s global voice network.

Symbio also says that the cloud native solution removes the need for on-premise infrastructure, significantly reducing hardware and deployment costs to support businesses as they migrate towards a cloud-based future.

The announcement follows Symbio’s initial entry into Singapore in 2021, making it the first fully inter-connected voice carrier to build local network capabilities in the country for more than 20 years.

The latest integration in Singapore builds on Symbio’s strong partnerships with Cisco in Australia and New Zealand, where the company provides cloud native calling capabilities for customers across enterprise and government sectors.

Symbio Co-Founder and CEO Rene Sugo said, “Bringing our unified communications offering to Singapore signifies a significant step in our regional business expansion strategy. We are proud to be setting the pace for innovation and disrupting Singapore’s telecommunications sector by giving customers access to Cisco cloud calling capabilities that were not previously possible in the country.”

"Today's employees are working from everywhere - from home, the office and anywhere in between. Whether they're calling, creating, sharing, or using voice or presence capabilities, they need to do it from a variety of devices and the experience needs to be seamless,” said Andy Lee, Country Manager, Cisco Singapore and Brunei,

“The ability to innovate and scale hinges on quality collaboration and communication including cloud calling. As the leader in cloud calling, Cisco and our Partners - such as Symbio - will deliver an end-to-end, secure calling experience with best-in-class innovations to customers."

Symbio says the seamless integration with Cloud Connect for Webex Calling will enable Cisco resellers to deliver a compelling end-to-end solution - and with Symbio’s fully integrated, cloud PSTN (public switched telephone network) service, Webex customers can now make calls from the home, office or anywhere in the world using one global provider.

Iain Falshaw, Chief Executive of Symbio’s UCaaS division said, “Symbio’s integration with Cisco will unlock collaboration opportunities for businesses across Singapore by giving them access to our global voice network. In the same way Symbio has provided this solution to Cisco partners in Australia and New Zealand we are very excited to be able to offer Cisco’s current and future partners in Singapore the same high-quality calling experience.”

Symbio’s integration with Cisco Cloud Connect for Webex Calling is available to Cisco value added resellers in Singapore from today.

Killexams : Tech multinational Cisco sets its sights on making Ennis a 'smart town'

Technology multinational Cisco announced plans to convert Ennis in Co. Clare into a “smart town” which will have better traffic management and increase footfall into shops.

This plan is part of a project by Cisco called the Country Digital Acceleration (CDA) which is expected to help increase investment in making countries more accessible through the use of technology.

“We're one of the most connected nations, yet the opportunity that presents isn’t felt by everyone. The last few years have brought the impact of digital exclusion into focus,” said Shane Heraty, managing director of Cisco Ireland and Scotland.

Cisco’s CDA programme first launched in Ireland in 2018 in support of the nation’s Project Ireland 2040 plan for social, economic and cultural development. Before bringing it to Ireland and setting its sights on Ennis, Cisco used its CDA programme on ambitious projects in other parts of the world.

It was previously used in South Korea where it introduced video conferencing technology into education institutions during Covid-19. It has also been used in Italy where digital tools were implemented to help the elderly contact their loved ones during the pandemic through large sharp screens with enhanced audio. 

The CDA project provided technology for IT talent development and network security in Japan as well. In addition, it was used in the US by industry to help create better IT solutions.

The plan for Ennis, which falls under the CDA, will be supported through a contract with State body The Western Development Commission (WDC). It isn’t completely clear how Cisco plans to make Ennis more digitised as the company did not disclose details of the project to the Irish Examiner before publication.

This joint venture between the WDC and Cisco is one of a few projects to be carried out along the west of Ireland. “The WDC’s mission is to work collaboratively to mitigate and overcome challenges at a regional level to ensure vibrant, connected communities throughout the West of Ireland,” said Tomás Ó Síocháin, CEO at WDC.

“Working with the experts at Cisco to close the digital divide in the region will help us do just that,” he said.

A pilot research programme in Clare Island, Co. Mayo, is also part of the WDC and Cisco contract. This will look into ways to make virtual healthcare in Ireland more accessible. Science Foundation Ireland, NUIG and the HSE are contributing to the research.

Mr Heraty says these projects will “complement” the work being carried out to implement the National Broadband Plan in rural areas. Research from the Centre for Economics and Business Research (CEBR), commissioned by Cisco, found that more digital opportunities in Irish industry could add €28bn to the Irish economy by 2030.

However, the technology firm indicated that implementing these projects won’t be enough to benefit from a digital economy.

The company said research suggested that 70,000 people a year must gain essential digital skills to be in an environment where everyone in Ireland can participate in a more digitised economy by 2030. This would include having access to online services like banking or virtual GP appointments.

Cisco also said that to build a more digital workforce, 131,000 need to develop a higher level of digital skills each year.

Under Cisco, Level 5 Certificates for digital skills courses will be offered through its Networking Academy in an effort to reach these goals. To date, Cisco has offered digital skills training to 30,000 people in Ireland.

Cisco first launched in Ireland in 1999 and has offices in Dublin and Galway.

It was originally founded in the US in 1984 by Stanford University computer scientists Sandy Lerner and Leonard Bosnack. They married after setting up the business but eventually divorced. Ms Lerner went on to co-found Urban Decay cosmetics.

Cisco has since grown to be an American-based multinational technology conglomerate corporation headquartered in San Jose, California, that sells networking hardware, software, and telecommunications. Cisco claims that over 85% of the world’s web traffic travels securely across its connections.

Killexams : WRAPUP 1-Cisco, Nike quit Russia, as pace of Western firms leaving speeds up

* Cisco, Nike join MacDonald's, Renault in quitting

* New Russian law may encourage more foreign firms to go

* 'Trickle is becoming a torrent,' says analyst

By Praveen Paramasivam, Supantha Mukherjee and Mimosa Spencer

June 23 (Reuters) - U.S. companies Cisco Systems and Nike plan to fully exit Russia, the two firms told Reuters on Thursday, as the pace of Western firms departing accelerated.

Telecoms equipment maker Cisco will wind down its business in Russia and Belarus, the company said. Nike is making a full exit from Russia three months after suspending its operations there, the sportswear maker said.

Foreign companies seeking to exit Russia over the war in Ukraine face the prospect of a new law being passed in the coming weeks allowing Moscow to seize assets and impose criminal penalties. That has encouraged some businesses to accelerate their departure.

"What was a trickle is becoming a torrent", said Paul Musgrave, a political science professor at the University of Massachusetts, commenting on the latest round of companies announcing they would leave.

Cisco suspended business operations, including sales and services, in Russia in March.

"We have now made the decision to begin an orderly wind-down of our business in Russia and Belarus," it said in an emailed statement on Thursday.

Earlier this month, Cisco's rival International Business Machines Corp began winding down its business in Russia and Microsoft said it was making substantial cuts to its Russian business.

The withdrawal of top technology firms such as Cisco, IBM and Microsoft limits access to critical equipment for Russian businesses and households. They may now have to depend on older equipment and domestic alternatives.

Cisco has offered relocation options to its few hundred employees in those countries, it said. The company did not disclose which countries the employees were offered as alternative locations.

RIVALS MAY BENEFIT

Companies heading for the exit may struggle to return, said Musgrave. "This presents opportunities for domestic firms in some markets but even more for brands from China and elsewhere to make inroads," he said.

Nike said on March 3 it would temporarily suspend operations at all its Nike-owned and operated stores in Russia. It has now decided to leave entirely, it said Thursday.

Cisco and Nike join the likes of McDonald's and Renault in making complete exits from Russia. More companies are expected to leave in the coming weeks ahead of the new law.

The law, which could be in place within weeks, allows Russia to appoint administrators over companies owned by foreigners in "unfriendly" countries, who want to quit Russia as the conflict with Ukraine drags down its economy.

Nike's rival Adidas said in March it was shutting its Russian stores and pausing online sales.

Adidas currently has no plans to resume business in Russia, the German sportswear company told Reuters on Thursday.

"The operation of Adidas' stores and Adidas' online retail in Russia continues to be suspended until further notice, this also applies to the delivery of goods to Russia," it said in an emailed statement.
