Which of the following is recognized as a serverless compute service in AWS?

AWS Lambda is recognized as a serverless compute service in AWS because it allows users to run code without provisioning or managing servers. With AWS Lambda, you can execute your application code in response to events, such as changes in data or in system state, without the need for traditional server management. This model is flexible and cost-effective, as users are billed only for the compute time consumed, and there is no charge when the code is not running.

The core principle of serverless computing is that it abstracts the infrastructure management away from the user, enabling developers to focus solely on writing code and developing applications. Lambda automatically scales applications in response to the number of requests, making it ideal for variable workloads where execution can be triggered by specific events.

In contrast, AWS Config and AWS OpsWorks are services for configuration management and orchestration, not for executing code. Amazon EC2 is a traditional Infrastructure as a Service (IaaS) model, where users manage the servers and resources, which does not fit the serverless compute paradigm. Hence, AWS Lambda stands out as the correct answer as it embodies the core features and conveniences of serverless computing.
