Serverless
Serverless is a cloud computing execution model where the cloud provider dynamically manages the allocation and provisioning of servers, allowing developers to build and run applications without managing infrastructure. It typically involves event-driven functions (like AWS Lambda or Azure Functions) that scale automatically and charge based on actual usage rather than pre-allocated capacity. This model abstracts server management, enabling focus on code and business logic.
Developers should learn serverless 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 variable traffic where paying only for execution time reduces costs compared to always-on servers. Use cases include real-time file processing, chatbots, and backend services that need rapid scaling.
