"BaaS" stands for Backend as a Service in cloud computing. This model provides developers with ready-to-use backend functionalities, allowing them to focus on creating the frontend of applications without worrying about the underlying server-side logic or infrastructure management. BaaS solutions typically include services such as database management, user authentication, push notifications, and cloud storage. By leveraging BaaS, developers can significantly speed up the application development process and ensure scalability, as the BaaS provider handles maintenance and upgrades.
