In cloud computing, 'WAS' stands for Web Application Services. This encompasses a set of services and tools that allow developers to build, deploy, and manage applications on the cloud. WAS facilitates the delivery of applications over the internet, eliminating the need for local installation. By leveraging cloud resources, organizations can scale applications easily, ensure high availability, and implement security measures effectively. These services streamline the application lifecycle management, improving operational efficiency and allowing businesses to focus on their core functions without extensive infrastructure investments.
