Software-as-a-Service (SaaS): With SaaS, the cloud allows users to access software applications over the Internet on a subscription basis eliminating the hassle of developing the entire software application.
Cloud storage: Since cloud-based storage has already replaced local hard drives as the norm in IT systems, it is one of the most prevalent use cases for cloud computing.
Serverless computing: Developers can create and execute applications using this cloud-native development methodology without needing to manage servers. With this, you may execute your applications without worrying about the back-end servers.
Disaster recovery: It is easier because the cloud offers flexibility, fewer complications, and, most crucially, less downtime. Additionally, prior data backup techniques had flaws due to physical disc corruption or stock issues.
Test and development: Without the drawbacks of setting up and managing on-premise IT resources, cloud computing offers ready-to-use, customizable, and fully configured resources for the testing and development of apps and services.
