Persistent Storage and Containerization
In the past few years, containerization is being considered as a most common way for packaging of software, and converting operating systems into a transportable and isolated modules that can be generated as well as destroyed as much as they are possible. But permanent storage is not allowed by containerization. The data that is being generated by the containerized app disappears once the app completes its function. For retaining the data generated by container container applications new software and storage is being recently developed by some vendors. These advances in the storage containers solves the problems of retaining of more ephemeral storage volumes.
What is Persistent Storage?
Any data storage system that keeps data after its power is turned off is said to be using persistent storage. It’s also known as nonvolatile storage at times. Persistent storage in the context of containerization refers to storage volumes that are accessible after a container has stopped running. These volumes are typically connected to stateful applications like databases. Ephemeral storage volumes, which are linked to stateless apps that live and die with containers, can be contrasted with persistent storage volumes.
