Google Professional Cloud Developer Exam - Topic 1 Question 106 Discussion

You are designing an application that uses a microservices architecture. You are planning to deploy the application in the cloud and on-premises. You want to make sure the application can scale up on demand and also use managed services as much as possible. What should you do?
B) Create a GKE cluster in each environment with Anthos, and use Cloud Run for Anthos to deploy your application to each cluster.
A) Deploy open source Istio in a multi-cluster deployment on multiple Google Kubernetes Engine (GKE) clusters managed by Anthos.
C) Install a GKE cluster in each environment with Anthos, and use Cloud Build to create a Deployment for your application in each cluster.
D) Create a GKE cluster in the cloud and install open-source Kubernetes on-premises. Use an external load balancer service to distribute traffic across the two environments.

D sounds risky, mixing cloud and on-prem like that?

I recall that using Istio can help with service mesh capabilities, but I’m not convinced it’s necessary for this scenario. I might lean towards option B as well.

I’m a bit uncertain about the differences between Cloud Build and Cloud Run in this context. I feel like I might be mixing up the deployment strategies.

I think option B sounds familiar because we practiced a similar question about using Cloud Run for Anthos. It seems like a good choice for scaling.

I'm a bit unsure about option D - using an external load balancer to distribute traffic across cloud and on-prem Kubernetes clusters. That seems like it could add unnecessary complexity compared to the Anthos-based solutions.

Yeah, option B does sound like the best fit. Anthos makes it easy to manage a consistent Kubernetes environment across cloud and on-prem, and Cloud Run handles a lot of the scaling and managed service aspects.

I'm leaning towards option B - using GKE with Anthos and Cloud Run for Anthos. That seems like it would give us the scalability and managed services we need across both environments.

Okay, let me think this through. We need to design a microservices app that can scale up on demand and use managed services as much as possible. The app needs to be deployed in the cloud and on-premises.

Cloud Build integration with Anthos is a nice touch, but I'm not sure it's necessary here. I'd stick with the more straightforward Cloud Run approach.
