AWS AppSync

AWS AppSync is a managed service that simplifies building and maintaining real-time data-driven applications by connecting multiple data sources like databases and APIs. It uses GraphQL, a flexible query language, to enable clients (such as web or mobile apps) to request exactly the data they need efficiently. AppSync handles tasks like data synchronization, offline access, and security, allowing developers to focus on application features without managing complex infrastructure. Essentially, it streamlines how applications communicate with backend data, making real-time updates and data management more scalable and reliable.
