DynamoDB

Monitoring

If an application’s read or write requests exceed the provisioned throughput for a table, Amazon DynamoDB might throttle that request. When this happens, the request fails with an HTTP 400 code (Bad Request), accompanied by a ProvisionedThroughputExceededException 

High Availability

• Scalability

  • Unlimited amount of storage

• Elasticity

  • Increase additional IOPS for additional spikes in traffic. Drecrease that IOPS after spike
  • We can increase or decrease read and write throughput capacity on demand
  • As read requests increase, we can increase read throughput capacity
  • As read requests slow down, we can decrease capacity
