The components of AME
Availability
- what factors affect the quality of service delivered by the system, and by how much/how long?
- how well can systems survive typical failure scenarios?
Maintainability
- how hard is it to keep a system running at a certain level of availability and performance?
- how complex are maintenance tasks like upgrades, repair, tuning, troubleshooting, disaster recovery?
Evolutionary Growth
- can the system be grown incrementally with heterogeneous components?
- what’s the impact of such growth on availability, maintainability, and sustained performance?
