Serverless Computing

A New Era of Cloud-Based Execution

Serverless computing is a cloud computing model in which the cloud provider automatically manages the infrastructure, allowing developers to focus solely on writing code. The term “serverless” does not mean there are no servers; rather, the servers are abstracted away from the developer and are maintained by the provider. This model offers a simplified deployment process, enabling teams to launch applications quickly without handling server configuration, scaling, or maintenance.

Serverless computing is a natural evolution from earlier models, where developers manage servers, which abstracts the environment for application development. Serverless takes this further by automatically scaling, managing, and provisioning resources based on demand, charging only for the actual usage.

Developers also had to monitor and scale the server manually to handle varying loads. In…
