Serverless architecture is a modern cloud computing model that allows developers to build and run applications without managing the underlying infrastructure. Despite its name, servers are still involved; however, the management of these servers is handled by cloud providers. This approach enables developers to focus solely on writing code, enhancing productivity and reducing operational overhead. Serverless architecture is particularly beneficial for applications with variable workloads, as it automatically scales resources based on demand. By leveraging services like AWS Lambda, Azure Functions, or Google Cloud Functions, businesses can optimize costs and improve deployment speed while maintaining flexibility and scalability.
