Architecture

While setting up a “Web Server on a Single Machine” architecture, is it fine to have the SQL DB on a SQL cluster instead of a separate dedicated server for UiPath purposes?
While Elasticsearch server is optional (but recommended), is it really necessary if we are looking at less than 5 bots in production? If we wish to scale up further at a later point in time, can Elasticsearch be added at a later stage and are there separate costs around it?

have anyone used orchestrator basic version instead of the standard for production if you are using single tenant only with <5 bots because that’s what it supports. Any pitfalls or problems faced or does it work well for single tenancy with 2-3 bots?
