What is important in distributed systems and what are the best ways to store state? • Understand that CAP Theorem stands for Consistency, Availability, and Partition tolerance and is important for data storage in distributed systems • Understand the shared database and database per service patterns, and how they are used in distributed systems • Understand how these patterns can be implemented with DynamoDB, RDS, Aurora or Aurora serverless Accessing DynamoDB from API Gateway Via a Lambda Function How can we expose data in DynamoDB externally? • Use API Gateway and a lambda function as a proxy • Create API methods such as GET and POST • Use the lambda function to shape the request into a DynamoDB query and parse the returned data for the API Accessing DynamoDB Directly from API Gateway Is there a simpler way to expose DynamoDB data externally? • Use API gateway direct DynamoDB integration • Use API gateway to shape the query in the integration request step • Use API gateway to shape the response in the integration response step Implementing the Transaction Log Tailing Pattern How can I implement the transaction log trailing pattern? • Use DynamoDB streams • Use a lambda function to consume the stream as an event source • Use a lambda to write the steam data to another table in DynamoDB Implementing the Saga Pattern How can I implement the saga pattern as a serverless stack? • Use SNS and lambda combination • Use step functions to build up a state machine in JSON using the Amazon states language • Use step functions states to invoke lambda functions Securing Your DynamoDB Databases How can I ensure that my DynamoDB database is secure?

• Enable encryption at rest
• Enable the VPC endpoint
• Use IAM policies that are locked down as much as possible to a specific table and with minimum permissions
