Explore Function as a Service (FaaS) platforms like AWS Lambda and Azure Functions.
Serverless computing is an evolution of cloud architecture that allows developers to build and run applications and services without thinking about servers. It doesn't mean there are no servers; it just means the cloud provider is responsible for managing the server infrastructure. The most common form of serverless computing is 'Function as a Service' (FaaS). With FaaS, you write your application logic in the form of functions, and you upload them to a platform like AWS Lambda, Azure Functions, or Google Cloud Functions. The platform executes these functions in response to specific events or triggers. An event could be an HTTP request from an API Gateway, a new file being uploaded to an object storage bucket, or a message being added to a queue. The key benefits of serverless are 'No server management', 'Pay-per-execution' (you are billed only for the exact time your code is running, down to the millisecond, so you never pay for idle capacity), and 'Automatic scaling' (the platform automatically scales the number of function instances to handle the incoming load, from a handful of requests to thousands per second). This makes serverless ideal for event-driven architectures, microservices, data processing tasks, and building APIs.
