The pattern with the most difficult abbreviation to pronounce, CQRS. (It helps to sing it instead.) The core of this pattern is to separate methods that change data from them that only query the data. This pattern can lead to an architecture that are very suitable for application in the cloud.
To help me to understand this pattern I interviewed Jonathan Worthington from Edument (@jnthnwrthngtn). He has a very good knowledge about this pattern and have also created a starter kit that can be used to learn CQRS.
