The document outlines 5 principles of modern application architecture. The first principle is to develop an adaptive architecture that can easily replace parts to reduce replacement costs rather than building for 10 years of robust support. The second is to develop a system of records that acts as a platform for business innovation rather than focusing innovation only at the business level. The third is to develop a functional core focused on key responsibilities and leave non-functional aspects like performance to cloud providers. The fourth is to make technology changes irrelevant to overall success rather than using only proven technologies. The fifth is to design systems that fail and recover fast rather than attempting to design systems that never fail.

2. Principle #1
Traditional Principle:
Build a future state architecture that is robust
support the application for the next 10
New Principle
Develop an “Adaptive Architecture” that
maximize ability to replace and minimize cost
to replace its parts

3. Principle #2
Traditional Principle:
Build an architecture with innovation at the
business to innovate
New Principle :
Develop a “System of Records” that is
strong enough to act as a platform for
business innovation.

4. Principle #3
Traditional Principle:
Build an architecture & solution that is
highly performant…
New Principle :
Develop an NFR enabled & assumed
“functional core” and leave non-functions
to the specialists like cloud providers etc.

5. Principle #4
Traditional Principle:
Use todays technologies that are proven,
supported…
New Principle :
Make technology change / experiment
irrelevant to the overall success

6. Principle #5
Traditional Principle:
Design a system that never fails…..
New Principle :
Failure is not an after thought. Design
systems that fails fast and recover fast.
