Hey guys need some help , i am new with mongodb and am considering to host a mongodb instance of my own for prod setup. We are seeing random memory spikes on mongo database instance from some days and we dont have much visibility. Any ideas or suggestions if hosting would be a good idea and any open source tools or articles to help in this

Hmmm. This is always tricky. You have to start somewhere to gain knowledge, but starting in production is always risky. You could probably start to gather knowledge on how to host Mongo correctly in dev and staging while procuring the prod instance as a managed service until you feel confident enough to take on the challenge. That said - probably the bitnami implementation is a good place to start as it has the basic things covered and needs mainly configuration: https://bitnami.com/stack/mongodb

Yeah i am currently planning for dev and once i have some confidence move to prod if it looks feasible to maintain. Thanks for the suggestion.
