Hashicorp Vault - AWS EKS vs EC2

bv flag

Is it possible to install a Hashicorp Vault cluster to EC2 only or is EKS required and would there be a big advantage to one over the other?

Vault runs on EC2 just fine. It is a a typical Kubernetes vs. Virtual machine descision. Vault has very little that's specific to it with that regard.

Running on virtual machine is generally more complex to setup because you'll have to provision storage, load-balancers, etc. But if you don't already have a EKS cluster ready and Kubernetes expertise it will be easier to deploy Vault on EC2.

Also, running on a virtual machine makes it easier to keep mlock enabled and hook to an HSM (Vault Enterprise only).

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
