Serverless Architecture is a cloud computing model in which the cloud provider manages the infrastructure, allowing developers to focus solely on writing code. In a serverless setup, developers deploy functions or services without provisioning or managing servers, as the cloud provider automatically handles scaling, load balancing, and server maintenance. Despite its name, "serverless" does not mean there are no servers involved; rather, it means that the management of those servers is abstracted away from the developer.

Serverless architectures are particularly well-suited for microservices, event-driven applications, and workloads with unpredictable traffic patterns. Popular serverless platforms include AWS Lambda, Google Cloud Functions, and Azure Functions. Serverless computing offers several benefits, such as reduced operational complexity, cost-efficiency (since you only pay for the compute time you use), and faster time to market. However, it also presents challenges, such as cold start latency and limited control over the underlying infrastructure. Despite these challenges, serverless architecture is increasingly adopted by organizations looking to build scalable, cost-effective, and agile applications.
