Java Enterprise Architecture Requirements: S.P.A.M.M.E.R.S

Section 2 (Common Architectures) of Java EE 5 Enterprise Architect Certified Master Exam has this: Explain the advantages and disadvantages of two-tier/three-tier/multi-tier architectures when examined under the following topics: scalability, maintainability, reliability, availability, extensibility, performance, manageability, and security. That's a lot of architectural requirements and the initial acronym is SMRAEPMS, which does't look easy to remember. Rearranging, we have:

S - scalability
P - performance
A - availability
M - maintainability
M - manageability
E - extensibility
R - reliability
S - security
