Serverless Computing – A New Era of Cloud-Based Execution

Serverless Computing – A New Era of Cloud-Based Execution

Comments 0 Comment

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. You can visit the detailed tutorial here. Serverless computing is a…
