Being in cloud is just a start \u2013 it’s even more important to take advantage of the special opportunities provided by cloud computing, one of which is the almost unlimited scalability of the applications and services you make available through the cloud. However, you first need to make sure the services you use are cloud-native and use orchestration services such as Kubernetes. The following overview of the architecture of one such system was prepared by our cloud experts.<\/strong><\/p>\n\n

First, the software and libraries required at the operating system level must be bundled using so-called containers.\u00a0Containers\u00a0<\/strong>use the kernel of the host operating system, but are separated from other containers and from the host at the process and file level. In addition, containers can be precisely configured in terms of the amount of resources they consume.<\/p>\n\n

Operating these containers within a cluster of virtual or physical computers requires the use of a\u00a0container orchestrator<\/strong>. Kubernetes represents the dominant container orchestrator on the market (with a market share between 80 and 90 percent, depending on the survey in question); Docker Swarm and Apache Mesos provide alternative orchestrator options but only play a minor role on the market.<\/p>\n\n

Kubernetes\u00a0<\/strong>was originally developed by Google and was released in 2014 as an open source platform for the automatic deployment, scaling and management of containerized applications. Today, Kubernetes is managed by the\u00a0Cloud Native Computing Foundation (CNCF)<\/a>. The CNCF was founded in 2015 as a non-profit organization, and is part of the Linux Foundation, which means that the continued development of Kubernetes is ensured well into the future.<\/p>\n\n

A business looking to use Kubernetes can either install it itself on-premise or in the cloud, or can make use of a managed Kubernetes cluster,\u00a0 though\u00a0market research (https:\/\/security.stackrox.com\/state-of-containers-and-kubernetes-security-report-winter-2020.html, no longer online) shows the number of self-managed Kubernetes installations is dwindling, while the use of managed Kubernetes cluster services is growing greatly.<\/p>\n\n
