I know, more control is an axiom! But the above statement is more often true. When we're talking about configuration control in the public cloud it can be especially true as control over the configuration of your application can put control in the hands of someone who knows less about the given platform and thus is more likely to get the configuration wrong. Have I fired you up yet? Then you're going to love (or loathe) my latest report, published today.
Let's look at the facts. Your base configuration of an application deployed to the cloud is likely a single VM in a single availability zone without load balancing, redundancy, DR or a performance guarantee. That's why you demand configuration control so you can address these shortcomings. But how well do you know the cloud platform you are using? Is it better to use their autoscaling service (if they have one) or to bring your own virtual load balancers? How many instances of your VM, in which zones, is best for availability? Would it be better to configure your own database cluster or use their database as a service solution? One answer probably isn't correct - mirroring the configuration of the application as deployed in your corporate virtualization environment. Starting to see my point?
Fact is, more configuration control may just be a bad thing.Read more
