colo fees are cheap if you need more than just 1u. even with a 50-100 fee you easily get way more performance and come ahead within a year
You originally said “a couple months” but now it’s 6 months and assumption of $0 collocation fees which isn’t realistic
In my experience situations rarely call for precisely 32 cores for a fixed period of 3 years to support calculations like this anyway. We start with a small set of cloud servers and scale them up as traffic grows. Today’s tooling makes it easy to auto scale throughout the day, even.
When trying to rack a server everyone aims higher because it sucks to start running into limits unexpectedly and be stuck on a server that wasn’t big enough to handle the load. Then you have to start considering having at least two servers in case one starts failing.
Racking a single self-built server is great for hobby projects but it’s always more complicated for serving real business workloads.
Everyone: run your scenarios and expectations in a spreadsheet and then use real data to run your CBA. Your case will be unique(ish) so make your case for your situation.
I think you’re misreading. Even the 6 month thread was based on invalid assumptions of $0 collocation fees. Add in even cheap collocation fees and it’s pushed out even further
That’s not really a nit pick when the claims were based on impossible math. It’s more of a Motte and Bailey where they come in with a “couple of months” claim that sounds awesome on the surface but then falls back to a completely different number if anyone looks at the details.
Let’s not forget that if even three engineers are working on this migration for only a week your cost is now 10’s of thousands for this couple hundred euros cost saving.
(assuming avg all-in engineer costs in europe)
It makes no sense to optimise cost for infrastructure mostly, it does make sense to make it faster, since almost all your spend is on engineers.
Spending thousands to save hundreds is not a healthy business.
