S3 Lifecycle Policies and Storage Classes

Learn how to use S3 storage classes and lifecycle rules to automatically move data to cheaper tiers and reduce storage costs over time.

Why Storage Classes Exist

Not all data is accessed equally. Recent uploads may be read constantly, while year-old logs are rarely touched.

S3 storage classes let you match storage cost to access frequency.

S3 Standard is the default: high durability, low latency, frequent access. It is the most expensive per GB but cheapest per request.

Great for active, hot data.
