Cross-Region Replication

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.

Edge locations

Edge locations are small pockets of computing, storage, and networking facilities mainly used for edge computing and high-speed content delivery. There are 218 edge locations in total.

Local zones

Select AWS services, like compute and storage services, have moved closer to more end-users, providing them with low latency access to the applications running locally. There are 12 local zones in total.

Replication

Replication in general terms means duplication or cloning.
