Cross-Region Replication
Explore AWS S3 cross-region replication to understand how it automatically copies objects between buckets across different AWS regions. Learn its benefits such as reducing access latency for global users, retaining key metadata, supporting diverse ownership, and meeting compliance requirements by storing data across distant locations. This lesson helps you apply replication techniques to enhance data availability and performance in AWS S3.
AWS global infrastructure
AWS offers a highly secure, reliable, and available cloud platform to develop and deploy applications globally within minutes.
Some benefits of having a robust infrastructure are listed below:
- Low latency and low packet loss
- Easy usage
- Highly reliable and available
- Fault-tolerant
- Highly secure
- High throughput
- Highly redundant networking
Regions
Regions are the largest physical hardware data centers managed by AWS. They can withstand large amounts of failure. There are 25 regions (both constructed and in-construction) in total.
Availability zones
Availability zones are slightly smaller data centers within regions that are closer to the users and store redundant data. They are used to facilitate high-speed and low latency network connectivity. Each region contains three availability zones. There are at least 81 availability zones in total.
