The modern web space has terms like serverless, CDN, edge, and cloud that are often used interchangeably but have distinct meanings. Serverless refers to a model where developers build and run applications without managing servers or infrastructure. A Content Delivery Network (CDN) is a global network of servers that hosts applications to get them closer to users, improving performance and reducing latency. The term "edge" can refer to both deploying content to CDNs and distributing computational tasks to the edge of a network for faster processing. Cloud refers to a collection of connected servers, data centers, and software that work together as a single entity, encompassing both the physical infrastructure and the services provided by cloud providers. Understanding these terms is crucial to navigate the tech landscape effectively.
