AWS (Amazon Web Services) offers various services and tools that allow developers to build and deploy applications without the need to manage infrastructure directly. These services fall under the category of “serverless” or “compute as a service” offerings, which abstract away the underlying infrastructure, allowing developers to focus on writing code and building applications.
Here are some of the key AWS services that enable serverless computing and building applications without infrastructure management:
AWS Lambda: AWS Lambda is a serverless compute service that lets you run your code without provisioning or managing servers. You can write your application logic as functions and upload them to Lambda. Lambda takes care of automatically scaling and managing the underlying infrastructure to run your code in response to events or API calls.

AWS API Gateway: AWS API Gateway allows you to create, publish, and manage APIs for your applications. It acts as a frontend for your serverless functions, allowing you to define API endpoints that trigger your Lambda functions. API Gateway takes care of routing requests to the appropriate functions and handles aspects like authentication, rate limiting, and caching.
AWS AppSync: AWS AppSync is a fully managed service that simplifies the process of building APIs for your applications. It supports real-time data updates and offline capabilities, making it suitable for building applications that require real-time interactions and synchronization across devices.
AWS Step Functions: AWS Step Functions is a serverless workflow service that allows you to coordinate and orchestrate multiple AWS services and Lambda functions as a series of steps. It provides a visual interface to define and manage the flow of your application’s logic.

AWS Aurora Serverless: Aurora Serverless is a managed relational database service that automatically scales your database capacity based on demand. It eliminates the need for manual scaling or managing database instances, allowing you to focus on your application’s logic.
These services, along with other AWS offerings like Amazon S3 for object storage, Amazon DynamoDB for NoSQL database needs, and AWS S3 for file storage, allow you to build applications without worrying about the underlying infrastructure. By leveraging serverless services, you can focus on writing code, deploying your application, and scaling it as needed without the overhead of infrastructure management.
