Nah, don't let that discourage you. You can probably start with a Postgres backend that will serve as your db, full text search, data warehouse, and even job queue. Load balancers in front of your stack are available from aws, etc. and are easy to set up. The rest, like a caching redis server, actual job queue, etc. you can add as you go if it becomes needed. Some language stacks let you run async operations and queues in the server itself which may be enough. There is no need for containers or complicated deployment processes. If you're on the JVM, for example, just create an uberjar and run that. Focus on things that actually bring value to your business and use the simplest, most minimal solution everywhere else. Don't give up on your idea because you feel overwhelmed. Good luck.
