https://aws.amazon.com/polly/ In late 2019 I https://aws.amazon.com/blogs/aws/aws-now-available-from-a-local-zone-in-los-angeles/ the AWS Local Zone in Los Angeles, California. In that post I described Local Zones as a new type of AWS infrastructure deployment that brings select AWS services very close to a particular geographic area.
Applications hosted in a Local Zone benefit from very low (single-digit millisecond) latency access to EC2 instances and other AWS services. Local Zones also give AWS customers additional choices regarding data residency, giving them the ability to store and process sensitive data (often financial or personal in nature) in-country.
Local Zones in Action AWS customers are working to put Local Zones to use.
