Best practices for multi-region architectures

Now that we understand most aspects of the DynamoDB global table technology itself, let’s review some best practices for using global tables in multi-region, globally available applications.

Avoid introducing cross-region dependencies

One essential best practice for maintaining a robust multi-region architecture in DynamoDB global table-based applications is to proactively prevent the introduction of cross-region dependencies. This principle underscores the importance of achieving regional isolation by routing requests to the appropriate regional endpoint of the application as early in the technology stack as possible. This strategic routing approach mitigates the need for cross-region database calls, which can inadvertently introduce latency and elevate the risk of errors stemming from network disruptions. Instead, by isolating requests to the specific regional endpoint of the application, you ensure the application’...
