How does AWS ensure high availability?
AWS (Amazon Web Services), a cloud computing service, ensures high availability by combining architectural design, automation, and redundancy. AWS's global architecture is built on regions and availability zone (AZs), designed to isolate and provide resilience. Each region is composed of several AZs. These are geographically separated data centers. AWS distributes resources across multiple AZs to ensure that, even if a data center has an issue, other data centers can continue to operate without interruption. This multi-AZ architectural design is essential for services such as Amazon EC2, RDS and S3, designed to replicate data and workloads automatically across different AZs.
AWS uses sophisticated software to monitor and manage services in addition to its physical infrastructure. Automating processes is key to maintaining high availability. AWS, for example, uses Auto Scaling, which automatically adjusts the number of instances that run a specific application according to demand. https://www.sevenmentor.com/am....azon-web-services-cl
