S3

Source: https://docs.aws.amazon.com/AmazonS3/latest/userguide/Welcome.html

  • Enable Life Cycle rules to delete old versions and move objects between storage tiers
  • Enable Object Lock when first creating the bucket to allow you to create a “write once, read many” bucket
    • Governance is when root can override objects
    • Compliance is when no one can override the objects

ClassMinimum Storage DurationDescription
StandardNoneDefault
Express One ZoneNoneHigh-performance, single zone
Intelligent TieringNoneAutomatically move objects, based on their access pattern. Small overhead cost

EC2

Instance TypeDescription
t2General purpose, uses credits
t3General purpose, unlimited credits
mGeneral purpose
cCompute optimized
rMemory optimized

Instance Stores

Source: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/InstanceStorage.html Some instance types have instance stores. These are effectively directly attached to the EC2 and are temporary storage. When you stop the EC2, any data on this temporary storage (instance store) is deleted.

EBS

Source:

There are a few different types of EBS volumes. Each have their performance and cost pros and cons. EBS Volumes can be snapshotted, very similar to VMWare Snapshots.
