Puppet Multi Tenancy
- 2 minsSo in a brake from my articles on Puppet adoption, I decided that I’d like to write up some of my experiance and thoughts on Multi-Tenancy. Before I go any further, this is not thoughts on multiple users having access to shared or segregated Puppet and the configuration and instilation of Puppet per user with segregated or shared masters, That’s a whole subject in it’s own right. For this discussion I am speaking to the segregation of concern in any organisation in regards the tasks required of Puppet and the management of configuration in regard these concerns. With that in mind I won’t be just speaking about Puppet, but ITIL and change management, security concerns and deligation, segregation of duty and concerns. The too long did not read (TL:DR) of that is who profides what requirments and why, and who fulfills what requirements where, with what and how, or the Where, What, Who and Why of DevOps.
If you were hoping for more on the Puppet Adoption series or you’ve not read them they’re linked in the footer I’m sure, but just incase, they start with Puppet Adoption 123 - part one and I’ll get back to them with Part 4 soon.
Where, What, Who and Why of DevOps.
I realised when I started to think more deeply about this subject it quickly became clear that what we are talking about is really scope of Influence, Concern, Capability and Visibility, and the keys are knowing Who influences Who and How, What each party is concerned with, Who as the capability to affect the requirements, and Who needs visibility of What from the system.
So I broke this down, now it was Who, What, and Where in relation to Influence, Concern, Capability and Visibility. But I also realised this subject needs or warrents it’s own multi-part artciles on multi-tenancy. Damn it. So without much further adue.
Who, What and Where of multi-tenancy
I’m going to think about it a little more and then provide articles on the subject, but my initial mind map looked like the below
