S3 Availability and Durability

• Durability:
  • S3 measures durability in percenatages
  • For example if the durability is 99.99999999999% this means we can expect an average annual loss of 0.000000000001% of objects => if you store 10,000,000 objects with S3 you can on averge expect to incur a loss of single object every 10,000 years
• Availability:
  • This is also measure in percentages.
  • The availability of 99.99 % means that there will be 0.01 % of the downtime for accessing files
• S3 has Storage classes which defines the durability and availability percentages as well as cost for accessing the data and storage
