> Your operational overhead will increase _a lot_. Be ready to hire on a lot of ops staff if you expect them to do anything but put out fires. And as you grow you'll need experts, people like network engineers.

Why? What are you talking about? You are hiring servers you are no colo'ing them. Networking them is not your problem. Your responsibility still starts from a root prompt just there's no VM layer between that and the physical server.

Yes, it really does look like @stephen-mw is talking about a migration to an owned/colocated hardware. And that's a very different kind of hairy mess I'd prefer to stay away from as long as humanly possible.

OMG, colo. I've been the architect of a Top 500 website acquired by a Top 100 and even for that we just rented a few servers (you'd be surprised how few -- a dozen or so). I do not really know how big you need to be make colo a sensible choice but quite probably much, much bigger than most think of. We ran the numbers and they weren't pretty.

And for cloud: we purchased video conversion as a service, that one ran in the cloud. I can see how that makes sense.

and if you have more than one? or more than one dc? somebody needs to connect it, or you will need a VPN. it's not that easy without Clouds if you need connected servers. We switched to AWS since connecting servers in a dc isn't as cheap as people think of.

This article was talking about renting servers from Softlayer. All servers on your account in Softlayer have a private VLAN that connects them, even between data centers. Private networks for your servers are a feature of many server hosts.

We get free inter-DC connectivity for free with Softlayer. There really is no difference for us between connecting to a server within a DC or between datacenters (aside from added latency, of cource) – the same private address space, the same access rules (we see all of our machines in a private backend network from any datacenter).

Every enterprise router in existence has built-in tunnel support. Even the open source ones like PFSense.

I host all my stuff with Hetzner (who are at the cheap end of the market compared to Softlayer) and even they provide pre-configured VLANS and private switches. For intra-DC you can just setup some redundant openvpn links or pay the dc to configure a hardware tunnel between both sites.
