Amazon Web Services officially launched its AWS London Region, offering two availability zones (data centers). The new London Region is currently available for multiple services, including Amazon Elastic Compute Cloud (Amazon EC2), Amazon Simple Storage Service (Amazon S3), and Amazon Relational Database Service (Amazon RDS).
The London Region joins Ireland and Frankfurt as AWS’ third European location. This brings the number of AWS Regions worldwide to sixteen, and the total number of AWS Availability Zones to 42.
