Is your company experiencing rocketship growth or are you at the point where your growth has stabilized to a modest figure? It's probably best to pursue growth over cost savings, if possible. But not every company is in a position where a few more features can double revenue.

Still, I think it's hard to justify going anti-cloud in an effort to cut costs. Without a very skilled and experienced team doing the migration, the end result is very likely to be some hybrid setup that's the worst of both worlds. Especially if you're using a managed service, the open source alternatives might not be the drop in replacement that they claim to be.
