What is Serverless Computing?
Serverless computing is a cloud computing execution model that allows developers to build and run applications without the need for managing server infrastructure. This model abstracts away the server management tasks, enabling developers to focus solely on writing code. With serverless computing, the cloud provider dynamically manages the allocation of compute resources.
One of the main advantages of serverless architectures is that they can automatically scale based on the application's demand. When there are spikes in usage, more resources are allocated automatically, and when demand drops, the resources are scaled down accordingly. This ensures that applications remain responsive while optimizing costs since users only pay for the compute power they consume.
Key services under serverless computing include Function as a Service (FaaS), where developers deploy individual functions that run in response to events, as well as Backend as a Service (BaaS), which provides backend services through APIs. Popular platforms offering serverless options include AWS Lambda, Google Cloud Functions, and Azure Functions.
In summary, serverless computing redefines how developers deploy applications, simplifying workflows and reducing operational overhead while providing substantial flexibility and scalability in cloud environments.
