12 reasons to choose Kubernetes

choose Kubernetes

We have summarized what we came across to choose Kubernetes into 12 items from the viewpoint of utilization value. Although there may be a part where my opinion is mixed depending on the thought, I attach a basis link. I think that Kubernetes will grow into a truly wonderful next generation IT infrastructure in the future,

Business benefits

Execution Foundation that enables frequent application releases

Automatic rollout and rollback of applications can be executed safely and smoothly by automating delicate tasks such as frequent new function releases and urgent bug fix replacement by Deployments.

High availability foundation suitable for unstoppable service

With Replication Controller realizing self-healing (self-recovery), we can build a service that will not stop.

Expandable base according to the business situation

Horizontal auto-scaling of the pod Horizontal Pod Autoscaling by, can be adjusted to an appropriate scale in line with the scale of the business, it can contribute to the sales compression unnecessary cost.

Operational advantages

Flexible operational infrastructure capable of hybrid configuration with virtual servers and bare metal

If you want to keep applications that are not suitable for execution in containers as they are in bare metal or virtual servers as is, and in the transitional state of modernizing applications, Headless services and Publishing services – service types , Kubernetes and Hybrid You can configure a system.

Infrastructure suitable for production operation of applications developed with containers

You can deploy to the Kubernetes cluster by specifying the repository address and image name of the registered container after developing and testing the application. Since all the connection destination information for switching from the development environment to the production environment are set in the k8s cluster environment, it is possible to start the container as it is in the production environment without changing any application.

Operational base available on both on-premise and cloud

Software products and supporting hardware products to run Kubernetes and Kubernetes service is offered by mega cloud vendor and will not be locked in a specific place.

Public cloud Kubernetes service

Operational Foundation with Orchestration

Kubernetes is a YAML file setting that can implement load balancer, horizontal distributed clustering, storage management, internal service discovery and domain registration, greatly improving operational productivity.

Technical advantages

Standard technology not controlled by a specific company

Although Kubernetes was originally a Google project, it has been donated to CNCF and the project is operated as an open source, and development is proceeding as a technology not dependent on a specific company.

Lightweight and highly efficient container technology

Container technology based on Kubernetes launches much more lightweight and faster than a virtual machine that emulates hardware. It is an excellent portability-executable image for packaging the stack of required software such as the OS, middleware, development language libraries, etc. that the application depends on as a container. It will be possible to minimize the difference between the development environment and the production environment, greatly contributing to productivity improvement in application development and operation.

Active development continues

The major companies in the industry, namely, mega cloud companies, software and hardware manufacturers participate actively and development continues.

Cost advantage

Use as a path to multi-cloud

Compatibility with other companies’ k8s environment is guaranteed by using the k8s infrastructure certified by CNCF “Kubernetes compliant certification program”. This makes it possible to use multiple k8s environments at the same time, which makes it possible to enhance business continuity and cost competitiveness by eliminating reliance on a specific company.

Elimination of waste by using high density server

Since Kubernetes is a container-based technology, it is not locked in to specific hardware or software configurations. Pods that are a set of containers are guaranteed to communicate and are subject to load balancing if they are within a k8s cluster on different servers. And the work involved in relocation is handled by k8s, and the number of pods is controlled by the strategy for maintaining performance at the time of migration, so you can relocate during production. This makes it possible to operate highly efficient infrastructure without waste.
