DAY 14 :📦 AWS Storage Types: Choosing the Right Fit for Your Needs

Storage in aws

1. Instance Store:

   • Temporary block-level storage.

   • Data is lost if the instance is stopped and started.

2. Block Storage (EBS):

   • Breaks data into blocks and presents them as a volume or hard drive.

   • Can be mounted and booted (OS installation possible).

   • Specific to an Availability Zone (AZ).

   • Servers in one AZ cannot attach an EBS volume from another AZ.

3. File Storage (EFS):

   • Stores data in a hierarchical structure of files and folders.

   • Accessible remotely by multiple machines simultaneously.

   • Cannot be used as a boot volume (OS installation not possible).

4. Object Storage (S3):

   • Stores objects (files) in a flat file structure without sub-directories.

   • Cannot be booted or mounted.

   • Suitable for static websites, media files, logs, traces, and audit reports.

   • Different storage classes affect accessibility, resiliency, and cost:

     • S3 Standard: Default and most expensive.

     • Standard-IA: Same reliability as S3 Standard but with a retrieval fee.

     • Glacier Instant: For rarely used files that need instant retrieval.

     • Glacier Flexible: Cheaper than Glacier Instant, but retrieval takes longer (5-12 hours for bulk, 3-5 hours for standard, 1-5 minutes for expedited).

     • Glacier Deep Archive: Cheapest option with the longest retrieval time.

This summary highlights the key features and limitations of each storage type, helping users choose the appropriate option based on their needs.
