Persistent Storage
Q.1: How data security is ensured with persistent storage?
Answer:
In order to ensure data security with persistent storage practices such as encryption, access control and backups are used. Use of secured connection and authentication is required for secured persistent storage.
Q.2: What is the use of cloud storage in persistent storage devices?
Answer:
Using cloud storage allows to store the data on remote servers. These servers are maintained by the cloud providers. Using cloud storage in persistent storage devices provides with redundancy, accessibility and scalability.
Q.3: What is the difference between persistent and non-persistent storage?
Answer:
The main difference between persistent and non-persistent storage is persistent storage saves the data even if the power is turned off whereas non-persistent storage erase the data once power is turned off.
Q.4: What are the applications where object persistent storage is used?
Answer:
Object persistent storage is used in applications such as big data analytics, cloud storage and content delivery networks.
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.
