[Amazon DocumentDB (with MongoDB compatibility)](https://aws.amazon.com/documentdb/) Elastic Clusters are now available in 4 additional regions - London (Europe), Seoul (Asia Pacific) , Mumbai (Asia Pacific), São Paulo (South America). DocumentDB Elastic Clusters are a new type of DocumentDB cluster that enables you to elastically scale your document database to handle millions of reads and writes per second with petabytes of storage. With Amazon DocumentDB Elastic Clusters, you can leverage the MongoDB Sharding API to create scalable collections that can be petabytes in size. You can start with Amazon DocumentDB Elastic Clusters for small applications and scale the clusters to handle millions of reads and writes per second, and petabytes of storage capacity as applications grow. Scaling Amazon DocumentDB Elastic Clusters is as simple as changing the number of cluster shards in the console and the rest is handled by the Amazon DocumentDB service, and can be as fast as minutes compared to hours when done manually. You can also scale down to save on cost at any time.
