When an application works with different public clouds When using multiple cloud services from different vendors What are Containers Used For?Ĭontainers are mostly used in the following scenarios: What unites the two is the requirement to meet the Open Container Initiative (OCI) and Kubernetes Container Runtime Interface (CRI) standards. There is a widespread misconception that Docker is all about containers only. Well, that’s not true and Docker is only part of the container ecosystem that consists of large, different projects.
