For 4 weeks now I use Graylog on one and same Virtual Machine, so MongoDB and Elasticsearch are on too. I am in work placement and one of my project is to make a infrastructure with graylog. I was thinking to start with 4 virtual machine 2 Graylog nodes and a cluster of 2 elasticsearch servers. But to be honest I am a little lost. Is it possible to make what I said above. Is it a good idea ? Do I need to install MongoDB on both graylog servers ? Do I need to deploy a Replica Set for MongoDB ?
I dont really know how to start. Later I will add for sure a loadbalancer but for now I dont even start the cluster, nothing is urgent now but after some search on the web i’m feel lost and confused about all of this.
It will be nice if someone can enlighten me.
Thanks for you help
