Which statement is true regarding agents in serverless monitoring?

The assertion that agents are not required for serverless technologies is correct. In the context of serverless computing, such as AWS Lambda or Azure Functions, the infrastructure management is abstracted away from the user. This means that there is no need for traditional agents that are typically installed on hosts to collect or monitor system-level metrics. Instead, serverless architectures operate on a pay-per-use model, where the cloud provider handles the server provisioning, scaling, and maintenance, eliminating the need for an agent-based monitoring approach.

Monitoring for serverless technologies typically relies on built-in cloud provider metrics and logs, which can be integrated with observability tools like Datadog for tracking performance, usage, and errors without the need for installing agents on the serverless components themselves. This allows teams to focus more on application development and less on infrastructure management.
