Advanced Monitoring and Optimizing with DynamoDB

Amazon DynamoDB is a key-value and document database that delivers single-digit millisecond performance at any scale. It's a fully managed database service with built-in support for advanced monitoring functionality.This intermediate course is the fifth in a series of courses in the Developing with Amazon DynamoDB curriculum.This developer-centric course introduces you to tools available to monitor and troubleshoot DynamoDB. You will explore resources to handle errors, monitor metrics, and respond to alarms. You will also implement DynamoDB optimization techniques to improve overall performance and lower costs.

• Course level: Intermediate

• Course duration: 210 minutes

Activities

This course includes animations, video demonstrations, interactive content, knowledge checks, and an optional (paid) self-paced lab.
