Summary

In this chapter, we have explored two key functionalities of CloudWatch: cross-account observability and cross-account cross-Region observability. Cross-account observability allows you to monitor resources that are located in different AWS accounts, making it possible to share and collaborate on monitoring data across multiple accounts. Meanwhile, cross-account cross-Region observability takes it a step further by enabling monitoring across multiple AWS accounts and Regions, providing a unified view of all the resources in use.

While these solutions offer many benefits in achieving observability for applications running under multiple accounts and Regions, we have also looked into their limitations when dealing with complex applications that are spread across multiple Regions and accounts.

In the next chapter, we will look into Well-Architected Framework and see how that could be applied to various observability services on AWS. Additionally, we will explore the Management...
