Google Professional Cloud Architect (PR000213) Exam - Topic 1 Question 27 Discussion

You need to deploy an application to Google Cloud. The application receives traffic via TCP and reads and writes data to the filesystem. The application does not support horizontal scaling. The application process requires full control over the data on the file system because concurrent access causes corruption. The business is willing to accept a downtime when an incident occurs, but the application must be available 24/7 to support their business operations. You need to design the architecture of this application on Google Cloud.What should you do?
D) Use an unmanaged instance group with an active and standby instance in different zones, use a regional persistent disk, and use a network load balancer in front of the instances.
A) Use a managed instance group with instances in multiple zones, use Cloud Filestore, and use an HTTP load balancer in front of the instances.
B) Use a managed instance group with instances in multiple zones, use Cloud Filestore, and use a network load balancer in front of the instances.

I agree, full control over the filesystem is crucial here.

Surprised they’d accept downtime, that’s a big deal!

Not sure about using unmanaged groups, feels risky.

I think A is better for HTTP traffic, right?

Option B seems solid with the network load balancer.

I practiced a similar question where we had to choose between unmanaged and managed instance groups, and I think unmanaged might be better for this scenario.

I feel like the network load balancer might be more suitable here since it handles TCP traffic better, but I can't recall the specifics.

I think we discussed something about using Cloud Filestore for file storage, but I'm not sure if it works with HTTP load balancers.

I remember that managed instance groups are great for scaling, but this app can't scale horizontally, so maybe that's not the best choice.

Easy peasy! Of course the security guards can check our IDs and bags - it's for our own protection. I'm going with A without a doubt.

This is a tricky one, but I think I can work through it. Let me think through the key steps in process improvement...

Okay, I think I've got a handle on this. If the WebLogic Server can't connect to the database, it's likely that the server won't be able to create the data source for the store. I'll go with option C.

I'm a bit confused on this one. I know XSS and SQL injection are big security risks, but I'm not sure if they're the best fit for this specific scenario. I'll have to review my notes on web application security to make sure I choose the right option.
