Typically, the container space originates with application containers that are not for permanently storing data. That is, when a container collapses, the data stored or buffered in the container gets lost. However, the aspect of data persistence is insisted for several reasons, including the realization of stateful applications, and hence fresh mechanisms are being worked out in order to safely and securely persist data in containers. Therefore, for persisting data, additional container types, such as data or volume containers were introduced.
Containers - persistent storage patterns
The context for persistent storages
There is a concern widely expressed that containers are great for stateless applications, but are not so...
