New Cisco Container Platform to Support Kubernetes Orchestrator

In its Cisco Live event, the company introduces its Cisco Container Platform, which becomes the latest addition to its hybrid cloud partnership with Google.

Cisco Systems expands its container capabilities as part of its broader multi-cloud initiative and multi-month partnership with Google around hybrid cloud deployment and management.

The company revealed last week that its latest software release for HyperFlex Hyper-Converters supports containers, which in an increasingly cloud-based world are becoming an alternative to virtual machines for deploying and running local and external applications. the market. the cloud.

At Cisco's Cisco Live show this week in Barcelona, Cisco officials presented the Cisco Container Platform, a software package based entirely on the open source Kubernetes container orchestration platform.

The measure adds to Cisco's previous container efforts, including the partnership announced nearly a year ago with the Docker Container Provider, which allows containers to be placed in Unified Computing System (UCI) devices. ) of the giant. networks.

The Cisco Container Platform is also a further step in the company's ongoing transition to a software and services provider role, with a focus on subscriptions and recurring revenue rather than sales. punctual material.

"One of the things that makes this new solution so appealing is that it helps customers take advantage of the potential of containers," said Kit Compton, vice president of Cisco's Cloud Platform and Solutions Group. a blog post. the company. "Containers start faster and use less memory than virtual machines, and allow developers to group applications together so they can work in a consistent and predictable environment." Containers can be run anywhere, allowing them to be used anywhere. development and their implementation much easier. "

All of these attributes have facilitated the rapid adoption of containers by businesses as they migrate to hybrid cloud environments (a mix of public clouds, private clouds, and local data centers) for business operations.

Kubernetes was born from internal projects that Google IT managers used to manage their internal container environments and has since become the ultimate container orchestration platform in a market that includes Mesos and Docker Swarm.

According to Tuan Nguyen, Cisco Cloud Center marketing technical engineer, this benefit can be seen in such recent moves as Kubernetes' support for integrating Kubernetes from Apache Mesos and Docker into its Enterprise Edition.

"In recent years, Docker Swarm, Mesos and Kubernetes have been involved in the duel to bring nirvana orchestration to containerized applications," Nguyen wrote in an article on the company's blog. "Although there are other participants in the scrum and while Mesos has had a longer performance, Kubernetes seems to be taking pole position."

Cisco managers are striving to position the company as the multiple cloud enabler, the idea that companies will not only be deploying much of their business to private and public clouds, but will include more than one public cloud.

The provider brings together hardware and software products, as well as services to help customers from the moment they begin to plan their migration to the cloud to implement, manage, and secure applications and data after the transfer. The multi-cloud strategy comes after Cisco abandoned Intercloud's effort last year to become a cloud provider.

The partnership with Google, announced in October 2017, is to create a cloud-based hybrid offering that will protect the millions of dollars businesses invest in their existing data center infrastructure while creating public cloud access.

At the same time, customers will be able to decide which workloads to transport in the cloud and which ones remain behind the company's firewall. The hybrid cloud effort includes Google Cloud Platform and technologies such as Apigee and Istio, powered by Google, and Google Kubernetes Engine.

"The Cisco Container Platform is the Next Step in Integrating Cisco's Open Hybrid Cloud Solution and Google Cloud ... to Our Customers

Initially, the platform will be available as software in Cisco HyperFlex 3.0 in April. In the summer, it will be available in VM infrastructure, bare-metal systems and in the public cloud. The platform will offer container cluster management capabilities ranging from configuration and orchestration to authentication, monitoring, networking and load balancing.
