UniversalContainers (UC) has an on-permise application for reporting damage to their shipments. They want to migrate the application to Heroku. The damage reporting process includes uploading one or more pictures to the application which temporarily stores them onthe local system. After the report is submitted, a case is created in UC's Salesforce org for processing, amd the images are deleted from the file system. The application's configuration is read from environment variables that are specified in the system user's profile. The application writes its logs to rotating files using an open-source library. Which two recommendations should an Architect make to ensure that the application runs correctly on Heroku? Choose 2 answers.

Not sure about that, seems like a bad idea to rely on local storage.

Wait, are we really deleting images after submission?

Loading config from source code? That sounds risky.

Definitely need an external storage for those images!

I think running in a Private Space is a must too.

Running the app in a Private Space could help with Salesforce integration, but I can't recall if that's necessary for all cases. Is that option C?

I feel like we had a similar question about using external services for file storage in our practice exams. Option B definitely sounds familiar.

I'm not entirely sure, but I think loading configuration from source code might not be the best practice on Heroku. Environment variables are usually preferred, right?

I remember we discussed the importance of using external storage for images in a cloud environment, so option B seems like a solid choice.

I think the two best recommendations are using an external object storage service for the images and running in a Private Space to connect to Salesforce. Those seem like the most straightforward ways to address the key migration challenges.

I'm a bit confused by the last option about writing logs to STDOUT instead of the file system. That seems like it could cause issues with log management and auditing. I'll need to research that one further.

Okay, the key here is to address the temporary image storage and integration with Salesforce. Using an external object storage service like S3 or Blob Storage makes sense for the images, and running in a Private Space could enable the Salesforce integration.

Hmm, using environment variables for configuration is a common practice, so I'm not sure why the question is suggesting to load it from the source code instead. That seems like an odd recommendation.

This seems like a straightforward migration to Heroku, but I'll need to think through a few key points to ensure the application runs correctly.

I believe option A is also important to ensure the application runs correctly on Heroku.

Option C seems like overkill for this use case. A private space isn't necessary to communicate with Salesforce.

I agree with Son. Option B will also help with scalability and performance.

Haha, 'WritP Inns tn stdmit'? Looks like someone needs to proofread their options a bit more carefully!

I'd also recommend Option D - writing logs to stdout instead of the file system. Heroku has a great logging system that can handle this for us.

Definitely agree with Raelene. Heroku's file system won't persist the images, so an external storage service is the best choice here.

I think option B is a good idea because it will help with managing the images.

Using Heroku's ephemeral file system to store temporary images is a bad idea. Option B is the way to go.
