It’s only silly if you’re not changing your processes. If you’re keeping the same people doing everything manually instead of automating, or honestly if you’re keeping the same headcount and if you’re not developing and depending on services provided by your provider and instead you’re self hosting services on VMs, of course you’re going to spend more.

But I blame most of the cost overruns when using cloud providers on “consultants” who think they are “moving to the cloud” when all they really know is how to setup a little networking infrastructure and know nothing about how to use the developer, Devops, or other hosted solutions.

Most ”consultants” I’ve run across only know how to do a lift and shift and do a one to one mapping of the on prem VMs and networking infrastructure to the cloud. They know nothing about automation, transforming Devops practices, or transforming development practices and architecture.

A lift and shift should only be the first phase.

If your company culture isnt devops no consultant will fix that.

Thinking that is the reason for consultants is a problem
