Difference between EA and RUP 4+1?

Question

What is the difference between Enterprise architecture and RUP (Rational Unified Process) 4+1 view on arcitecture?

Is it similar alternative to EA or its the same?

IMHO EA = business + information + technology + applications

while the 4+1 RUP architecture is connected only to the IT of an company, not needed to solve IT Governance etc. What do you think?

Answer 1

EA has some frameworks for describing some levels of organisations. These levels are strategies, business process, IT services and technologies for that services. EA frameworks have activities and artifacts for representing these levels. In fact, after applying EA, we have some descriptions of "services" or "application" for supporting business processes of organizations. Now for implementing each service or application, we use "RUP 4+1 view" for representing the "architecture" of that system. In fact, this concepts can link to each other for implementing the service of the organization.
