What is AWS Lambda primarily used for?

Running EC2 Instances
Serverless computing
Data storage management
Container orchestration

The correct answer is: Serverless computing

AWS Lambda is primarily associated with serverless computing, which allows developers to run code without needing to manage servers. It operates on a pay-as-you-go pricing model, meaning you are charged based on the compute time your code consumes, rather than for idle server time. This enables you to focus on writing and deploying your code without the overhead of provisioning or scaling infrastructure. In serverless architectures, AWS Lambda handles the execution of your applications in response to events, such as changes in data state, HTTP requests, or triggers from other AWS services. This event-driven design facilitates creating applications that automatically scale and can respond quickly to changing workloads without manual intervention. This focus on executing code in response to events differentiates Lambda from the other options. For instance, running EC2 instances involves the management of virtual machines and requires manual configuration and scaling. Data storage management typically involves services like Amazon S3 or Amazon RDS, while container orchestration pertains to managing containers, often with AWS services like ECS or EKS. Thus, using Lambda for event-driven tasks aligns it with the core principles of serverless computing, making it the correct choice.
