Kubernetes bootcamp

Introduction Kubernetes (also written k8s) is a powerful container orchestration platform that works with Docker. This first video provides a high level explanation of how kubernetes differs from traditional application deployment and infrastructure management. Overview A kubernetes cluster is made up of masters and nodes. The masters are responsible for orchestration and the nodes host… Continue reading

Orchestration moves containers from laptop into the datacenter. Kubernetes does that in a way that simplifies development and operations. Unfortunately I struggled to find easy to understand high level descriptions… Continue reading

In the context of long running servers in fixed locations, this was often an effective approach. As virtualization and container technologies become more prevalent, especially in public cloud, infrastructure focused IT controls… Continue reading

Virtualization, process isolation, resource sharing and other forms of flexible infrastructure have been in use for many decades in IT systems. It can be seen in early Unix systems, Java application servers and… Continue reading

What database products/versions are available How can I access the server directly? There are a few reasons that the questions above are not relevant for CloudFoundry (or any… Continue reading
