Amazon DynamoDB highlights from the last 18 months you may have missed
Amazon DynamoDB is a nonrelational database that delivers reliable performance at any scale. It’s a fully managed, multiregion, multimaster database that provides consistent single-digit millisecond latency, and offers built-in security, backup and restore, and in-memory caching.
This blog post recaps DynamoDB highlights from the last 18 months. Read this post to learn how to fuel your cloud transformation by lowering your total cost of ownership (TCO) while improving the scale, performance, and availability of your database.
1. AWS purpose-built databases, such as DynamoDB, give you the ideal tools for your application
As you migrate workloads to the cloud, you can forgo the one-size-fits-all approach of running monolithic relational databases for your applications. Learn about purpose-built databases so that you can choose the right tool (database) for the right job (application), with DynamoDB as your nonrelational database cornerstone.

2. DynamoDB has added many new capabilities over the last 18 months
DynamoDB has launched a steady stream of features such as encryption at rest, backup and restore, Amazon DynamoDB Accelerator, Time To Live, and global tables. Watch the following video or read the accompanying slide presentation to learn the history of DynamoDB at Amazon and how we continue to innovate on your behalf so that you can focus on code and not on operations.

3. DynamoDB delivers a 99.999% service level agreement (SLA)
AWS designed DynamoDB with uptime in mind. As of June 2018, DynamoDB has a 99.999% uptime SLA. Read more about the DynamoDB SLA.

4. Adaptive capacity makes capacity planning easier
For uneven access patterns and nonuniform workloads, DynamoDB adaptive capacity enables your application to continue reading and writing with consistent performance.

5. Automate backing up and restoring your database with point-in-time recovery and on-demand backups
DynamoDB launched continuous backups and point-in-time recovery (PITR) earlier this year. These features enable you to automate backing up and restoring your database to any single second in the preceding 35 days. No maintenance or code is required to enable PITR.

6. Global tables: DynamoDB is the only multiregion, multimaster database service
With global tables, DynamoDB is the only multiregion, multimaster database service. You can use global tables to run multiregion solutions that meet your most stringent business continuity requirements. You also can use global tables to enable low-latency data access to end users from anywhere in the world.
7. Customers are migrating to DynamoDB from other databases such as Cassandra
Companies such as Samsung and GumGum have migrated from Cassandra to DynamoDB and lowered their TCO by up to 70% as a result. Perhaps the biggest benefit of migrating to DynamoDB is that you can focus on business innovations and not on keeping your databases up and running.
