Evolutionary Architecture
●About architecng a system specifically for change
●About have a goal to head towards
●Helps think about quality
○Is scalability and security something to consider?
○What level of scalability is needed?
○What level of data protecon is needed?
●Define architectural fitness funcon
○What maers to your system?
■Security
■Upme
■Mean me to repair
●Delay decision as long as you can
●Understand various forms of technical debt
●Implement evidence-based re-use
○Not the center of architectural decisions though
●Create and maintain the tesng safety net - quality assurance
●Monitor your system
Why?
●Pace of change is increasing rapidly
●Business model lifemes are shortening
●Business need to be able to respond to change more quickly that before
Evolutionary vs Emergent
Evolutionary
Emergent
●About engineering architectures in such a
way that we can connuously evolve them
●Having a goal towards which the
architecture evolves
●Well defined fitness which guides the
evoluon
●Fitness funcon help evaluate architectural
decision and respond to changes in a more
informed way
●Changes are addressed more at ad-hoc
basis
●No clear criteria for change
Fiteness Function
Specifies important characteriscs of a system
