Serverless Architecture
Serverless architecture is a cloud computing execution model where the cloud provider dynamically manages the allocation and provisioning of servers. Developers write and deploy code in the form of functions or applications without worrying about underlying infrastructure, such as server maintenance, scaling, or capacity planning. It typically operates on an event-driven basis, with resources automatically scaling up or down based on demand, and billing is based on actual usage rather than pre-allocated capacity.
Developers should learn serverless architecture for building scalable, cost-effective applications with minimal operational overhead, especially for event-driven workloads like APIs, data processing, or IoT. It's ideal for microservices, batch jobs, and scenarios with unpredictable traffic, as it eliminates server management and reduces time-to-market. Use cases include web backends, real-time file processing, chatbots, and scheduled tasks, where you pay only for compute time used.
