Kubernetes and Cloud Native Associate (KCNA) — Question 123

Which of the following scenarios would benefit the most from a service mesh architecture?

Answer options

• A. A few applications with hundreds of pod replicas running in multiple clusters, each one providing multiple services.
• B. Thousands of distributed applications running in a single cluster, each one providing multiple services.
• C. Tens of distributed applications running in multiple clusters, each one providing multiple services.
• D. Thousands of distributed applications running in multiple clusters, each one providing multiple services.

Correct answer: D

Explanation

Option D is correct because a service mesh architecture is particularly beneficial in managing the complexity of thousands of distributed applications across multiple clusters. This scenario requires advanced traffic management, security, and observability features that a service mesh provides. The other options, while they may benefit from a service mesh, do not present the same level of complexity or need for management as option D.
