Instana provides specific monitoring for serverless compute platforms like AWS Lambda. This is accomplished by using an Instana Lambda Layer or by including an Instana library directly in the function's code. This component acts as the "serverless agent," enabling in-process tracing and performance metric collection for the function's executions. This method provides deep visibility into the serverless application's performance, which is distinct from the metric-polling approach used for other managed services.

A. Azure Redis Cache: This is a managed caching service monitored by the Instana Azure sensor, which collects metrics via Azure Monitor APIs, not a serverless agent.

C. AWS Kinesis: This is a data streaming service. Instana monitors it via the AWS sensor, which pulls metrics from AWS CloudWatch, not by deploying an agent.

D. AWS SQS: This is a managed message queue. Like Kinesis, Instana monitors it through the AWS sensor by collecting metrics from AWS CloudWatch.

1. IBM Documentation, Instana Observability, "Monitoring AWS Lambda": "Instana offers monitoring for AWS Lambda functions. The monitoring is done by including an Instana library in the function's code or by including the Instana Lambda Layer." This document details the specific mechanism for Lambda, which functions as the serverless agent.

2. IBM Documentation, Instana Observability, "AWS Sensor - Monitored Services": This page lists Amazon SQS and Amazon Kinesis as services monitored by the AWS Sensor. The monitoring approach described for these services is based on collecting metrics from AWS CloudWatch, not deploying an in-process agent.

3. IBM Documentation, Instana Observability, "Azure Sensor - Monitored Services": This document lists Azure Cache for Redis as a monitored service. The monitoring is performed by querying the Azure Monitor API for metrics, which is different from using a serverless agent.
