Summary

In this chapter, we thoroughly examined DynamoDB global tables and their benefits for supporting geographically dispersed user bases and ensuring disaster recovery readiness. We explored the inner workings of global tables, including the different versions available. We also discussed the complexities of operating and managing global tables, such as converting a single-region table into a global table, and the associated cost considerations. Additionally, we addressed data consistency and conflict resolution, focusing on cross-region consistency and DynamoDB’s conflict resolution mechanisms. Finally, we provided a detailed overview of best practices for designing multi-region architectures, stressing the importance of minimizing cross-region dependencies and actively monitoring replication lag.

In summary, DynamoDB global tables provide an effective way to scale applications globally, ensuring high availability and minimal latency for users. By following best practices...
