A serverless application is one that does not require the developer to manage the underlying infrastructure or servers. Instead, the application code is executed by a cloud provider in response to events or triggers, such as HTTP requests, database changes, or messages. The cloud provider automatically provisions, scales, and manages the resources needed to run the code, and charges only for the time and resources consumed by the execution. A serverless application runs from an ephemeral, event-triggered, and stateless container that is fully managed by a cloud provider. This means that the container is created on demand when an event occurs, and is destroyed when the execution is completed. The container does not store any persistent state or data, and is isolated from other containers. The cloud provider handles the load balancing, fault tolerance, security, and monitoring of the container. A serverless application can leverage various cloud services, such as databases, storage, messaging, analytics, and machine learning, to perform complex tasks and functionalities. Serverless computing is a cloud-native development model that enables developers to focus on the business logic and deliver faster and more scalable applications. References:
