This practice had a certain logic to it: we needed ......

Services, designed right, have much more runtime autonomy than components. That autonomy gives you much more ability to manage the security, reliability, and reusability of the encapsulated logic, although there can be a small cost in system performance. And service autonomy makes changes quicker and easier. That ability can save your bacon from time to time, just like it did for me one morning when I got to work....
