Mate, looking for a new MacBook Pro? Well, just hack a little JCR-based web app. Day has just announced the JCR Cup 2008, a JCR development competition. I will not be able to enter (I'm on the jury), but I reckon I'll write some examples just for the fun of it. Subscribe to dev.day.com if you're interested.
Lately, I had a lot of conversations about multi-tenancy (MT). So I finally wrote up my thoughts on that term. In this post I will argue that MT is a value that depends on a continuous variable. Therefore, any statement about a system being “MT” can only be made in the context of the given requirements. It is not a property of the system itself . I will also show that perfect multi-tenancy is indistinguishable from single-tenancy (ST). MT is a value that depends on a continuous variable Imagine a step-function "ST-MT" (values are either 0 or 1) that determines if a given system is MT (1) or ST (0). That function will look like this: ST-MT = function (system, business requirements) Look at the function’s arguments: the first one is obvious – the result will depend on the system itself. The second one is more interesting: it is the cumulative set of business requirements . Typically, these requirements will include: Resource sharing: systems typically declare...
