Which function does the FASTMAP algorithm NOT perform?

The FASTMAP algorithm focuses primarily on optimizing and managing microservices within a cloud-native environment. Its responsibilities include assessing and validating service deployments to ensure they function correctly.

The function associated with "Service rollback" typically refers to reverting a service to a previous stable state after an unsuccessful update or deployment. This function is generally outside the scope of what FASTMAP is designed for. Instead, it emphasizes real-time deployment and optimizing service performance rather than managing historical state changes.

On the other hand, functions like "Service dry-run," "Service check-sync," and "Service re-deploy" align well with the capabilities of FASTMAP, as they involve preparing for deployment, synchronizing service states, and redeploying services, respectively. These are proactive steps taken to ensure that services are operating optimally in a constantly changing environment.
