Re: Cassandra 4 alpha/alpha2
A new thing like this would be much better served by the community through several iterations. For instance, over the last year I've developed a tool for spinning up lab clusters, it's here: https://thelastpickle.com/tlp-cluster/ I had to make a *lot* of tradeoffs here. Everything Jeff mentioned, plus a handful of others. I'm pretty sure if someone where to try to accomplish the same thing they'd go about it a different way. It might be better or worse in a variety of ways. I agree with Jeff that these are problems better solved elsewhere, at least till an idea matures enough to adopt it. Otherwise we're creating a lot of technical debt that needs to be maintained, when we really need about a dozen prototypes that get thrown out first. Sharing work with the community, whether it be through packer, AMIs, or home made tooling is the first step here.

Re: Cassandra 4 alpha/alpha2
Lots of this, but also getting into the weeds, it's pretty clear this is nontrivial: - If we did an AWS AMI, would we also do Azure? GCP? AliCloud? OCI? Where do we stop? - What if there's a security hole in the base image - who's responsible for fixing that? We could have tooling that makes a new one every day, but that tooling has to run somewhere, who's going to pay for it? - What base OS? Do we do Amazon Linux or CentOS or Ubuntu or Debian? How do we choose? PV or HVM? - Which region? How long do we keep it? If we're doing nightly AMIs to pick up security fixes in the base image, what do we do with old AMIs? If we yank them we may break people, if we dont they may be using something with a security hole. All of these are solvable problems, but we're just not at a point where we're going to solve them at the project level anytime soon.

Re: Cassandra 4 alpha/alpha2
That is indeed what Amazon AMIs are for. However if your question is “why don’t the C* developers do that for people?” the answer is going to be some mix of “people only do so much work for free” and “the ones that don’t do it for free have a company you pay to do things like that (Datastax)”. Keep in mind, that when you create AMIs you’re using AWS resources and whoever owns the account that did the work, is on the hook to pay for the resources. But if your question is about whether you can do that for your own company, then obviously yes. And when you do so at first it’ll be about C*, then it’ll be about how your company in particular likes to monitor things, and handle backup, spec out encryption of data at rest, and deal with auth security, and deal with log shipping, and deal with PII concerns, and … Which is why there isn’t really a big win to other people setting up an AMI for you, except in cases where they are offering whatever-it-is-as-a-service and get paid for its usage. 1000 consumers will say they want a simple thing, but all 1000 usages will be a little different, and nobody will like the AMI they get if their simple thing isn’t present on it.

Re: Cassandra 4 alpha/alpha2
Hi, I have tested both alpha and alpha2 and 3.11.5 on Centos 7.7.1908 and all went fine (I have some custom images for my own purposes). Update between alpha and alpha2 was just about mere version bump.
