Not for all the projects I saw, but most of the projects were using Elasticsearch, which is very common. In my case, I have faced two scenarios with the solution. Other than that, generic solutions like SNS, SQS, and Lambda are some of the very generic tools we are using. Regarding what I would like to see improved in the solution, I would say that, basically, the configuration part is an area with a shortcoming. We have a DevOps person, so all these things are configured in the Terraform through the Terraform script we use. The DevOps team used to take care of it. To run the process or run the services and how to use the services are the parts for which we are using the solution. Some upgradation is required on the configuration side so that we can get to use it. In that case, I have to check on that area with the DevOps.
