Amazon ElastiCache now supports Global Datastore in the Asia Pacific (Hong Kong, Hyderabad, Jakarta, Malaysia, Melbourne, Thailand), Africa (Cape Town), Canada West (Calgary), Europe (Milan, Spain, Zurich), Israel (Tel Aviv), Mexico (Central), and Middle East (Bahrain, UAE) Regions. Global Datastore is a feature of ElastiCache that provides fully managed, fast, reliable, and secure cross-Region replication. Using Global Datastore, you can write to your ElastiCache cluster in one Region and have the data available for read in two other cross-Region replica clusters, thereby enabling low-latency reads and disaster recovery across Regions.
Customers use Global Datastore for real-time applications with a global footprint, as it provides cross-Region replication with latency of typically under one second, increasing application responsiveness by providing geo-local reads closer to end users. In the unlikely event of regional degradation, one of the healthy cross-Region replica clusters can be promoted to become the primary cluster with full read and write capabilities. Once initiated, the promotion typically completes in less than a minute, allowing applications to remain available. To secure cross-Region data transfer traffic, Global Datastore uses encryption in transit.
To get started, you can set up a Global Datastore with an existing cluster, or create new clusters and designate a primary (active) cluster. Creating a Global Datastore takes only a few clicks in the AWS Management Console for ElastiCache
or can be automated by downloading the latest AWS SDK or AWS CLI. For pricing and the regional availability, refer to the Amazon ElastiCache pricing page
