Sort of. "Locked in" is a strong word, considering Redis will run on AWS just fine, either by buying their product or spinning up a couple EC2s and `docker run redis` (which is allowed under the license since you aren't reselling it). Yes, harder than clicking a button in the AWS console, but it's not like you're stuck completely.
I understand it more for OpenSearch, because scaling that is annoying, but Redis has built in cluster mode stuff that works fine without having Amazon's magic control plane.
(we're also using OpenSearch hosted by AWS but not for anything complicated, so haven't encountered what you have. seems like Elastic 7.10, frozen in time, which is fine for us. they forked the old version of the .NET library for people to continue using, but I guess you need to use the archived docs.)
