Introducing single-Region architecture
Amazon has multiple data centers localized in a Region, with each data center referred to as an Availability Zone (AZ). These zones are separated from each other. Customers can choose to deploy their infrastructure in any AZ present in a Region (single-Region deployment), based on the location of their users. In this section, we will review the reliability requirements for different components while deploying applications in a single Region. This can be a single AZ deployment or deployment across multiple AZs. We will explore some sample architecture for the workloads that have single-Region deployment requirements.
Why customers choose single-Region architectures
Customers prefer to deploy applications in a single Region for various reasons, including easier management, reduced complexity, lower costs, and improved performance. A single-Region deployment can also provide better data locality and reduced latency. Additionally, it can be...
