When selecting a new Solution there are certain considerations to think about:
Ability for the end user to be as self-reliant/ self-serve as possible
The solution is configurable without impact upgrades
Multi-tenant cloud is better than on-premise individual instance
Ability for the application to be interoperable/ loosely coupled with the existing architecture/ other solutions
The solution takes into account security and privacy by design
The following leverages solutions outside of the application:
Integration. Need a way to get in/out of the application using published APIs and using integration orchestration from an enterprise tool
Data & Analytics (enterprise reporting is consolidated outside of the application). Production reporting sits within the application.
Identity and Access Management can be leveraged from outside the application
