S3 Essentials:

  • As AWS' main storage service, S3 can serve many purpose when designing highly available, fault tolerant, and secure application architecture, including:

    • Bulk (basically unlimited) static object storage.
    • Various storage classes to optimize cost vs. needed object availability/durability.

    • Object versioning.

    • Access restrictions vis S3 bucket policies/permissions.

    • Object management via lifecycle policies.

    • Hosting static files & websites.

    • Origin for CloudFront CDN.

    • File shares and backup/archiving for hybrid networks (via AWS Storage Gateway).

Important S3 Facts:

  • Objects stay within an AWS region and are synced across all AZ's for extremely high availability and durability.
  • You should always create an S3 bucket in a region that makes sense to it's purpose:
    • Serving content to customers.
    • Sharing Data with EC2.

S3 Read Consistency Rules:

  • ALL regions now support read-after-write consistency for PUTS of new objects into S3.
    • Object can be immediately available after "putting" an object in S3.
    • All regions use eventual consistency for PUTS overwriting existing objects and DELETES of objects. - means there may be a slight delay for other people to see the overwritten/deleted objects.
