What is persistent disk in Google Cloud?

Last updated on September 25, 2022 @ 8:00 pm

Persistent disks (PDs) are disks that can be used as persistent storage for data that needs to be preserved after a server or container is stopped or restarted. When you create a PD, you specify the amount of space that it will take up, and the disk will be automatically provisioned and initialized.

You can use PDs to store data that you want to keep available even if the server or container is restarted or stopped.

PRO TIP: Persistent disk is a durable, high-performance block storage option for Google Compute Engine and Google Kubernetes Engine instances. Persistent disks offer many benefits, including:

-Performance: With persistent disks, you can achieve consistent and high performance for your applications.

-Durability: Your data is stored redundantly across multiple servers in Google’s data centers. In the event of a hardware failure, your data is automatically replicated to another server so that it remains available.

-Security: Your data is encrypted at rest and in transit.

For example, you might use a PD to store the application’s data files. If the application were to stop or be restarted, the data files would still be available.

You can also use PDs to store data that you want to keep available even if the server or container is deleted.

PDs are automatically initialized when you create them, and they are accessible from the Google Cloud Platform Console. You can use the Google Cloud Platform Console to create, delete, or list PDs.
