Cloud Computing

Cloud Computing is the delivery of computing services—including servers, storage, databases, networking, and software—over the internet ("the cloud"). Instead of owning their own computing infrastructure or data centers, companies lease access to anything from applications to storage from cloud providers like AWS, Azure, or Google Cloud.

This domain is critical because it allows businesses to scale rapidly, reduce costs, and innovate faster without managing physical hardware. Cloud Architects and Engineers design and maintain these vast digital landscapes, ensuring high availability, security, and performance for millions of users.
