In large companies / governments / ... most of the time the application architecture needs to follow a set of rules (focused on maintainability and security).
These could be rules like the following:

  • The applications need to be developed following a Multitier architecture
  • Each tier should be physically separated for security.
  • The business logic tier is the only one that can connect to the data tier.
  • The presentation tier only connects to the business logic tier.
  • The presentation tier may not directly connect to the data tier.
  • The presentation tier is located in a DMZ, other tiers are heavily secured.
  • ...
Each project / company will have its own rules but the concept stays the same.
