Explain the advantages and disadvantages when each of them examined under the following topics: scalability, maintainability, reliability, availability, extensibility, performance, manageability, and security (flexibility)
This is more like an interview question
Many of them are self describing entities. You yourself can get to know if you think a bit about them.
Scalability - the ability to have more systems involved - the growth of the system/features etc.,
Availability - it may be interrelated with Reliability - the ability of the application to be available and providing access by different means or ways. Say through a web browser, mobile phone etc.,
Reliability - the ability to which the system can be trusted in case of failures, unexpected errors etc., An ideal system should have the facility to intimate the user about the errors and handle those exceptions in a graceful manner
Performance - the ability of a system to respond to the user's queries as early as possible. As performance is an abstract concept, it may be applied on variety of things like memory, time etc.
Security(flexibility)? Security is all about deciding who can be allowed to access the system and who can not? I don't think what the term flexibility can do here in security as all it can do is either permit or deny the user's request.
