Dedicated servers are all about what you want to do. Instead of sharing a server through shared hosting, all of the space is dedicated to what you are going to build. Dedicated server space is sold by hosting providers for various rates that can range from $45 to $250 plus. Mostly this depends on the size of the server, but some hosting providers will throw in a few extra things to entice you to sign up.
The OP claims that you need about 16 GB for one server, and an additional 8 GB per extra instance you want to run. This is in line with the amount of RAM the system itself will take up combined with the amount of RAM the game server will be using up after you've left it running for a couple of days. The game is - yet again - still not fully optimised, and there are still some mem. leaks present. If you don't believe me, yet again - go to the Squad Hosting Discord and ask for some usage graphs. Most of the time this amount of RAM won't be a necessity, but you could have performance issues if your RAM fills up. Not that it matters, as the dedicated boxes you'll be looking to rent will all offer more than 16 GB, anyway.
Dedicated hosting server providers utilize extreme security measures to ensure the safety of data stored on their network of servers. Providers will often deploy various software programs for scanning systems and networks for obtrusive invaders, spammers, hackers, and other harmful problems such as Trojans, worms, and crashers (Sending multiple connections). Linux and Windows use different software for security protection.
Unlike a shared server, which powers multiple sites, a dedicated server hosts just one site. Website stability and reliability are the twin benefits of investing in a dedicated server—your site leverages a server's full CPU, RAM, and storage resources, as it doesn't share them with other sites. You shouldn't underestimate the importance of these benefits in terms of site speed and reliability.
Availability, price and employee familiarity often determines which operating systems are offered on dedicated servers. Variations of Linux and Unix (open source operating systems) are often included at no charge to the customer. Commercial operating systems include Microsoft Windows Server, provided through a special program called Microsoft SPLA. Red Hat Enterprise is a commercial version of Linux offered to hosting providers on a monthly fee basis. The monthly fee provides OS updates through the Red Hat Network using an application called Yum. Other operating systems are available from the open source community at no charge. These include CentOS, Fedora Core, Debian, and many other Linux distributions or BSD systems FreeBSD, NetBSD, OpenBSD.
