I'm starting to host my first web app on a VPS but I dont yet have any experience managing a server. I want to minimize the costs of hosting but also reduce the hassles which a 1 man startup can bear with.
I'm not sure what would a better choice for me in terms of the operating system for my VPS. My web app is based in Java(JSF) using Cassandra(NoSQL) database. I am planning to learn the server side stuff for few weeks before I bring my sites into production. Could you recommend an OS for my first VPS?
