Cloud computing is a computing paradigm where information and computational resources are delivered as a service over the Internet. It allows users to access technology-enabled services from anywhere without requiring specialized hardware or software. The main advantages are low cost, scalability, and simplified access to applications and data. Potential disadvantages include security concerns, loss of control over certain aspects of the IT infrastructure, and vendor lock-in. A final piece of advice is to start with a pilot project to test cloud adoption before fully committing resources.
