common Architectures - SCEA 5 Certification.

[Prasanna Lakshmi Tallapaka]

Hi,

Could any one please be so kind to help me if my understanding is correct w.r.t the common architectures at the link http://java.boot.by/scea5-guide/ch02.html.

1) If the flexibiliy, reliability and availability increases, as shown in the attachment, Manageability descreases. (Sorry, I am not able to attach the ppt or the doc files. Could you pelase let me know the file format for the attachment. Thank you.)
2) If the architecture is capable to handle the Capacity and Manageability of the Application, the Reliability and Availability are challenged.

Hence is it implicit that these are the Trade-offs for a architect with his clients. If so, how to handle the scenario for a better architecture. :s

Many Thanks and Regards.
