Application Architecture and Enterprise Architecture

In this essay, Scott W. Ambler compares effectively these two concepts that include the term architecture and the roles of application and enterprise architects.

In his book Patterns of Enterprise Application Architecture, Martin Fowler compiles a set of patterns useful for application architects in charge of developing enterprise applications. This book does not include patterns suitable for enterprise architects. Whilst the work of application architects can be considered mostly technical (despite they have to have other skills on other knowledge areas and virtues related for example to management of people), the work of enterprise architects is more close to the political/diplomatical branch of IT. This book can be a good source of information for enterprise architects.
