Cloud Computing and AWS
Cloud computing is the delivery of computing services over the internet, providing on-demand access to a wide range of resources such as computing power, storage, and databases. AWS is a leading cloud services provider, offering a vast global infrastructure that enables users to access these resources and build sophisticated applications with ease.
AWS Global Infrastructure
AWS operates from a global network of data centers, known as regions. Each region is a separate geographic area with multiple availability zones (AZs). Availability zones are distinct data centers within a region, isolated from each other to ensure high availability and fault tolerance. As of the latest updates, AWS offers 25 regions worldwide, with plans for more in the future.
