Maintaining Objects Across API Deployment Instances
I am working on a web application as a hobby and trying to learn some concepts related to cloud development and distributed applications. I am currently targeting an AWS EC2 instance as a deployment environment, and while I don’t currently have plans to deploy the same instance of my API application to many servers, I would like to design my application so that is possible in the future.
I have a search operation that I currently have implemented using a Trie. I am thinking that it would be slow to rebuild the trie every time I need to perform the search operation, so I would like to keep it in memory and insert into it as the search domain grows. I know that if I only wanted to have one server, I could just implement the trie structure as a singleton and dependency inject it. If I do this in a potentially distributed application, though, I would be opening myself up to data consistency issues.
My thought was to implement the trie in another service and deploy it separately and make requests to it (this sounds like micro service concepts, but I have no experience with those). Is this common practice? Is there a better solution for maintaining persistent data structures in this way?
