Creating a software system is a lot like constructing a building.
If the foundation is not solid structural problems can undermine the integrity and function of the building.
When architecting technology solutions, if you neglect the five pillars of operational excellence, security, reliability, performance efficiency, and cost optimization it can become challenging to build a system that delivers on your expectations and requirements.
Incorporating these pillars into your architecture will help you produce stable and efficient systems.
This will allow you to focus on the other aspects of design, such as functional requirements.
