I'm a startup founder, and we're preparing to setup our vectorstore to train an LLM. I'm curious how we will setup our server architecture to separate some of our data, and make sure the LLM can't access it in case of prompt hacking. At the same time, we will want our LLM to be able to retreive answers from and generate responses from the vectorstore will will host our customers data. Does anyone have advice on structuring the Azure Database, or video or documents I should review?
