Amazon Elastic Block Store (EBS) provides persistent block-level storage volumes for use with Amazon EC2 instances. Think of an EBS volume as a virtual hard drive that you can attach to your virtual server. EBS Volume Types are:
| Volume Type | Description & Use Case |
|---|---|
| General Purpose SSD (gp3, gp2) | The best balance of price and performance for most workloads. Ideal for boot volumes, web servers, and development/test environments. |
| Provisioned IOPS SSD (io2 Block Express, io1) | High-performance SSDs designed for I/O-intensive, critical workloads like large relational or NoSQL databases. |
| Throughput Optimized HDD (st1) | Low-cost Hard Disk Drive (HDD) designed for frequently accessed, high-throughput workloads like big data processing, data warehousing, and log processing. |
| Cold HDD (sc1) | The lowest-cost HDD storage for less frequently accessed data where the primary requirement is low storage cost. |

Step 3: Configure Instance
