Here are the seven primary characteristics of an IT infrastructure (the “ilities”):
Usability
Maintainability
Scalability
Reliability/Availability
Extensibility
Portability
Security
Please select one of the seven characteristics above and respond with an example of what this term means in terms of IT architecture and why it is so important to a solid architecture to support information systems. These terms can be applied to other aspects of IT and business in general, but the focus here is on IT architecture. Some additional research will provide specific examples including what companies have focused on in these areas. Simply typing "IT Scalability" (or whatever characteristic you select) into your web browser should provide good results, but be sure to evaluate the sources to make sure they are relevant to this discussion. Remember to distinguish between objective articles and vendor's marketing information.
