This past week has been crazy for work. I was involved in a migration of servers from one hosting data center back to our company. The team I work with worked a lot of hours to make sure that everything went smoothly. Happily all of our hard work paid off. We were at work at 2 in the morning on Saturday switching over our applications.
One of the applications we moved provides seamless login functionality for other applications - through web services. It is amazing how much complexity this adds to a move because of how many applications are dependent on its web services. it also highlights the need for applications that leverage web services to be constructed in a way so that they fail gracefully.
