Distributed computing CALM - ness or not


Distributed computing and coordination is not a necessary evil, it is an incidental requirement of a design decision

The key insight in CALM is to focus on consistency from the viewpoint of program outcomes rather than the traditional histories of storage mutation. The emphasis on the program being computed shifts focus from implementation to specification: it allows us to ask questions about what computations are possible.

Interesting article and some good insight. Worth a read.
