Exam Professional Cloud DevOps Engineer topic 1 question 84 discussion

Option D allows for continuous testing of multiple versions of microservices, meets the traffic splitting requirements, and provides the necessary flexibility for controlling traffic based on user-agent headers, making it the most suitable choice based on the specified acceptance criteria.

Why not B?

OPtion D This option offers a comprehensive solution that aligns well with your criteria. Anthos Service Mesh, integrated with Google Kubernetes Engine (GKE), supports advanced traffic management capabilities, including the ability to perform traffic splitting based on HTTP headers. This would allow you to use the user-agent header to identify Android devices and direct traffic accordingly. Additionally, it supports arbitrary percentage-based traffic splitting and allows for the testing of multiple versions of a microservice, meeting the requirement for continuous testing.

This option provides a powerful combination for microservices deployment. Google Kubernetes Engine offers a robust environment for containerized applications, and Anthos Service Mesh (built on Istio) enables sophisticated traffic management. You can configure traffic splitting and direct traffic based on headers (like user-agent for Android devices), which aligns perfectly with your requirements.

Anthos Service Mesh allows for traffic routing based on HTTP headers such as the user-agent, which can be used to direct traffic from Android devices to an Android-specific microservice. Anthos Service Mesh supports arbitrary percentage-based traffic splitting. Google Kubernetes Engine with Anthos Service Mesh allows for continuous testing of multiple versions of any microservice. You can deploy different versions of your microservices as separate Kubernetes deployments and use Anthos Service Mesh to control the traffic between them.

D is correct
