This is an informative and well written article, but seems incomplete in this day and age. In public cloud environments, network attached storage is far more prevalent, so the swap story may be different there (I honestly don't know though). Since the author works at Facebook, he probably lacks experience in this regard.

Every cloud provider I've worked with (okay, so AWS :P) gives you ephemeral local storage. Obvioulsy you don't swap onto a network drive.

Even on AWS they're phasing out local storage on new instance types: https://ec2instances.info/ (search for ec2 only, but it's the majority of new instance families)

Modern AWS instance types are EBS-only.

With the exception of the High IO types (I2/I3). They still get it and the newer instances get NVMe SSDs. In other words they are making it a feature of certain types that would benefit from it.

[_msw_]

For example, F1 instances have NVMe local instance storage.

Huh. You're right; it seems for the newer instance types only c1.medium and m1.small get swap mounts. That seems like a mistake by aws; but I guess you can a M3 instead of a M5.

well the default kubernetes install (kubeadm) will actually fail installing when having swap enabled. (even worse you can force him to ignore that, but kubelet would fail starting when swap is enabled).
