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, stateless functions (e.g., AWS Lambda, 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, sporadic traffic patterns, and rapid prototyping, as it reduces deployment complexity and optimizes costs by charging only for execution time. Use cases include real-time file processing, chatbots, and backend services where infrastructure management is a bottleneck.
