• Amazon EBS (Elastic Block Store):
  • Block-level storage volumes for EC2 instances.
  • Supports various volume types and features.

Volume Types:

• General Purpose SSD (gp2):
  • Balanced performance for a wide range of workloads.
• Provisioned IOPS SSD (io1):
  • High-performance storage for critical applications.
• Throughput Optimized HDD (st1):
  • Low-cost storage for frequently accessed, throughput-intensive workloads.
• Cold HDD (sc1):
  • Low-cost storage for infrequently accessed, large-data workloads.

Volume Lifecycle:

• Volume Creation:

  • Create volumes during EC2 instance launch or independently.
  • Choose size, type, and Availability Zone.

• Snapshots:

  • Point-in-time copies of EBS volumes.
  • Used for backup, recovery, and cloning.
  • Incremental and stored in Amazon S3.

Volume Encryption:

• At Rest Encryption:

  • Encrypts data at rest to protect sensitive information.
  • Uses AWS Key Management Service (KMS) keys.

• In-Transit Encryption:

  • EBS data is encrypted in transit between the instance and storage.

Use Cases:

• SSD (General Purpose) - gp2:

  • Boot volumes for EC2 instances.
  • Low-latency, balanced performance.

• SSD (Provisioned IOPS) - io1:

  • Databases with high I/O requirements.
  • Critical applications demanding consistent performance.

• HDD (Throughput Optimized) - st1:

  • Big data, data warehousing, log processing.
  • Frequent data access with high throughput.

• HDD (Cold) - sc1:

  • Infrequent access, archival storage.
  • Long-term backups, cost-effective storage.

Tips for the Exam:

• Understand the differences between EBS volume types and when to use each.
• Familiarize yourself with snapshot creation and how they're used for backup and recovery.
• Know the benefits of EBS encryption and how to manage encryption keys with KMS.

Use this comprehensive mind map as a reference while studying Amazon EBS for the AWS exams. It covers the volume types, lifecycle, encryption, and use cases associated with EBS, helping you grasp the key concepts effectively.
