S3 Storage Classes (Storage Tier) – cost, durability, and availability – can be changed manually or using lifecycle policies.
Object : The percentage over a one-year period that an object in S3 will not be lost. Durability Object : The percentage over a one-year period that an object in S3 will be accessible. Availability Continue reading “[AWS] S3 Storage Classes and Versioning”
