1:	As in question 3 from Chapter 4, consider a widely used Web site, such as Amazon or eBay. What tactics would you need to consider when choosing the architectural patterns or architectural strategies for meeting the performance requirements you enumerated in that question?
2:	Given the set of tactics you chose in question 1, what tradeoffs with other quality attributes might you expect from using them (such as security, availability, and modifiability)?
3:	Usability is not always given due consideration in architecture design, making usability system goals often difficult to achieve because they are treated as an afterthought. Think of a system where you are familiar with the architecture and try to enumerate the usability tactics, if any, it has employed.
