I just found this interesting site on which the team of Ron Jacobs (product manager for Microsoft's Patterns & Practices team) has been working for educating folks on Architecture - check out Skyscrapr and see what they are saying about themselves:
"You can't build a stable system without a good plan. And you can't develop a good plan without a strong model that fits the needs of the organization. A coherent vision of how all of a system's parts need to come together that protects you. Without a plan you risk inefficiency, or even chaos, for your organization.
How essential is good system architecture? It can be the difference between growth and stagnation, availability and breakdown, or success and failure.
Skyscrapr is your window on the architectural perspective. Discover the different disciplines of system architecture, as well as perspectives on building successful systems. Check out our architects' blogs, learn about industry trends, download webcasts, watch videos, find training, and more."
