On the contrary, the bigger you get, the more you need Datadog to scale. Once you grow big enough, you can make volume deals with them, you don't pay list price. I'd much rather pay them than have a single engineer have to spend any time managing infrastructure that isn't core to our product, especially since Datadog will always do it better.
I respectfully strongly disagree. At a certain scale when you can afford to have a full-time engineer working on it, open source tooling will give you a better, cheaper and more flexible solution since it's easy to customize. Datadog is good for the mainstream cases but it's not all that flexible for unusual or edge cases.
