I'm going to launch a new web service, but i have few funds to start this business. I was taking a look at OVH Dedicated Infrastructure servers, but such a service costs at least 250 $/month, too much for me at the moment. Why i was looking at a Dedicate Infrastructure? Because i would run the Web Server on a machine, and perform database replication on another physical machine, in a private network (OVH Infrastructure allows me to create a virtual private network between my servers). Costs are too high for me at the moment, but meantime i wouldnt renounce to Database Replication. Therefore i thought i could buy a good dedicated server (not cloud, 4c/8t - 32 GB RAM - 3TB SDD) where to run LAMP, and then replicate mysql DBs to another small server, even a cheap VPS, setting up SSL for the mysql user who will run replication.
My questions are:
- which are the security risks in set up replication in a not private network?
- is SSL enough to hide traffic data between the web server and the other one?
- how hard is sniff packets from a web server, considering that OVH is a professional company which provides the best in terms of security? And if someone is able to do so, which are the risks i may meet?
Many Thanks.
