Public cloud storage volume types – GCE, AWS, and Azure
In this section, we'll look at some of the common volume types available in the leading public cloud platforms. Managing storage at scale is a difficult task that eventually involves physical resources, similar to nodes. If you choose to run your Kubernetes cluster on a public cloud platform, you can let your cloud provider deal with all these challenges and focus on your system. But it's important to understand the various options, constraints, and limitations of each volume type.
Many of the volume types we will go over are handled by in-tree plugins (part of core Kubernetes), but are in the process of migrating to out-of-tree CSI plugins. We will cover CSI later.
Amazon EBS
AWS provides Elastic Block Store (EBS) as persistent storage for EC2 instances. An AWS Kubernetes cluster can use AWS EBS as persistent storage with the following limitations:
- The pods must run on AWS EC2 instances...
