Provisioned Capacity and DynamoDB Autoscaling

Having understood what scalability is, it’s time to learn how DynamoDB interacts with it. There are two ways to configure scalability in this database. Both these options bring benefits in terms of performance and money, which is why understanding them well is crucial. In this lesson, we’re going to discuss provisioned capacity and the implications of implementing it.

What is provisioned capacity?

As discussed in the lessons regarding RCU and WCU, these two metrics are used to configure capacity for tables in DynamoDB. They determine the throughput that tables will have.

When configuring a table in DynamoDB with provisioned capacity, we’re giving it a fixed throughput for reads and writes.
