What is the purpose of Istio Service Mesh?

BProvides an infrastructure layer that makes communication between applications possible, structured, and observable.

CProvides dynamic application load balancing and autoscaling across multiple clusters and sites.

Show Suggested Answer

Suggested Answer: B

The VCF 9.0 Service Mesh Integration Guide defines Istio as: ''Istio Service Mesh provides an infrastructure layer that transparently handles service-to-service communication, securing, observing, and controlling traffic between microservices.'' The key purpose is enabling structured and observable communication between applications. While Istio includes discovery and load balancing, those are features, not the overarching purpose. A centralized routing table (Option D) is not the core definition. VMware documentation highlights Istio's role in service-to-service communication, observability, and policy enforcement within the service mesh. Therefore, the correct answer is B.

I think the purpose of Istio Service Mesh is to provide an infrastructure layer that makes communication between applications possible, structured, and observable. That sounds like option B to me.
