Co-locate database with client application

[lmastalerz]

Describe the pattern you'd like to propose
Deploy both database and client application in the same physical location to limit network traffic.

Describe specific emission impact from this pattern
Regarding SCI = ((E *I) * M) per R, E will decline due to reduced network traffic.

References to this pattern
N/A

Additional context
Presumably to be tagged as "Database"

Thanks for your suggestion.

Can you check if these existing patterns cover your idea?

Thanks for looking into it @markus-ntt-seidl !

Reduce transmitted data - it seems to cover the amount of data and not the "distance" the data has to cover

Choose the region that is closest to users - this is closer, but looks like it covers communication between server and end user and not necessarily internal communication between system components

Last one is probably the closest. The language used there seems to be very specific to VM's, if we could generalise it a bit I think this item should cover the pattern I had in mind. So something like "placing resources in a single geographical location" or ""placing components..." as opposed to more specific "placing VMs in a single region or a single availability zone"
Shall we also add more tags there so it covers all the resources?

I think we have to discuss the answer internally, there is also #217 with a similar question.

Currently the project discussions are taking a vacation and will be soon(tm).
