What is Red Hat, VMware, Cisco's "Commercial Kubernetes"?The differences are: Basic knowledge of container network [7th]

VMware has acquired Pivotal Software, which provides Kubernetes support functions and services, and Pivotal Software, which provided container -related features in the same Dell Technologies group as PaaS (Platform as a service).VMware is a vendor with a strong hypervisor, but by promoting these initiatives, it has evolved into a vendor for hypervisor to containers.

In addition to M & A, VMware also provides a Kubernetes -based product group "VMware Tanzu" to build and operate modern applications, enabling Kubernetes container cluster (Kubernetes cluster) in various infrastructure.。The company has added Kubernetes functions to version 7 of the "VMware VSphere", a flagship product, a server virtualization software.In addition, we are working to cooperate with Kubernetes for network virtualization and storage virtualization products.

Cisco Systems Kubernetes related products

Cisco Systems offers "Intersight Kubernetes Service" (IKS) as a Kubernetes product for on -premises infrastructure.IKS is a service included in the "Cisco Intersight" of infrastructure management SaaS (Software as a Service), and can deploy (deploy) a Kubernetes cluster on the infrastructure managed by Cisco Intersight.Cisco IKS can deploy Kubernetes to "Cisco Hyperflex", a Cisco Systems hyper converted infrastructure (HCI) product, and realizes container operation in Cisco Hyperflex.

By linking the "Cisco Application Central Infrastructure" (Cisco ACI) of the SDN (software definition network) product, the communication control of the Kubernetes cluster based on the network policy is also realized.In the future, in addition to the operation of containers operating in HyperFlex, we will also consider cooperation with public cloud container management services.By linking on -premises infrastructure with public cloud Kubernetes, you can create and manage Kubernetes clusters across both infrastructure.

Kubernetes that is important in hybrid cloud

The Kubernetes products introduced so far are all compliant with the Kubernetes Software Conformance "Kubernetes Software Conformance" of the CNCF (Cloud Native Computing Foundation).Kubernetes Software Conformance's Kubernetes products are compatible, so you can operate the applications built with any Kubernetes as they are.

The major difference between the Kubernetes product introduced in this article and the Kubernetes itself is that the construction of the Kubernetes cluster can be simplified.Patch management for node OS and upgrade of Kubernetes cluster can be easily executed using the GUI (graphical user interface) and CLI (command line interface).

Vendors for on -premises infrastructure are promoting not only on -premises infrastructure, which is originally good, but also for building and operating Kubernetes clusters with cloud services.These vendors also offer products to centrally manage on -premises infrastructure and cloud service Kubernetes.There are Red Hat's "Red Hat Advanced Cluster Management for Kubernetes", VMware's "VMware Tanzu Mission Control", and IKS of Cisco Systems.

The background of vendors to strengthen investment in Kubernetes is that Kubernetes has become a de facto standard as a container orchestrator, as well as a hybrid cloud (on -premises infrastructure and cloud service mixed environment) and multiple cloud services (multiple cloud services.The use of a mixed environment may be expanding.Kubernetes is standardizing by compliance with CNCF's Kubernetes Software Conformance in CNCF.This means that any application that can be executed in any Kubernetes can be executed in the same way, whether on -premises infrastructure or public cloud, if the Kubernetes cluster is configured.

Let's explain a little more specifically.When using Kubernetes, the application is encapsulated as a container image (a file that summarizes the elements required for application execution), and the application method is coded as a manifest (definition of the Kubernetes cluster resource configuration).These container images and manifests can execute applications in the same Kubernetes cluster, both on -premises or in the cloud.Kubernetes has been attracting attention as an element that realizes application operations in hybrid clouds and multi -cloud due to these advantages of "portable".
