The only downside I see is that going through the deployment process, it seems that the smallest instance I can provision is 2vCPU/16GB which if I'm looking at the pricing table correctly, equates to $230/mo. for a single instance.

The web console only lets me create a cluster with minimum 2 instances so it seems like I'm looking at $460 minimum to deploy Alloy. That feels a bit excessive.

You're looking at Cloud AlloyDB sounds like? If you deploy AlloyDB to GCE (instead of locally, etc) you can provision a smaller instance than that. 2cpu(shared core)/4GB memory with a 20GB boot disk (AlloyDB takes up ~13) would run you $26/month before network/storage costs.

Just my $0.02 here: if Cloud AlloyDB can deploy a big cluster, it seems like such a small stretch to take the same pipeline and deploy a small instance instead.

Yah, I know. The Cloud version has a lot of stuff happening behind the scenes that makes it a bit trickier to have a smaller machine configuration. It's being worked on, but I can't speak to timelines/configurations.

I’ve gotta say without unambiguous and long term unencumbered licensing, preferably with open source attached, I can’t foresee recommending any place I’ve got influence at to even look at it yet. Hopefully you can push them in a direction that is plausibly usable by anyone other than hobbyists. Even as a local dev tool it leaves too many holes open in the licensing and distribution model. Letting a team build a process and workflow around a time bomb would be negligence. It’s sad to characterize this as such, but we’ve all been burned too many times by globo mega corp whims.

100% hear you. I realize this may sound hollow coming from a Google employee, but stay tuned on specifics around licensing and costs. Being a tech preview, there's been virtually no discussion on specifics yet. We just wanted to get the tech in folks' hands. We're pushing hard for a free tier of usage (and the product team isn't pushing back currently).

Not hollow! Good luck.

Fair but maybe drop the open source tag on the blog post, since it’s not?
