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.
Ample RAM (5GB or more), e-commerce options for selling products, 24/7 customer service, and unlimited monthly data transfers are highly sought-after features, too. Many web hosts cap their dedicated monthly data transfer offerings at 16GB, which is probably fine for most users. Some web hosts offer unlimited monthly data transfers, but they are few and far between, and you need to read the terms of service very carefully to understand just what "unlimited" means to the host in question. In addition, companies that offer dedicated web hosting typically offer daily backups, security options, and malware detection and removal—all very important factors in your website's day-to-day operation.
All of these features may look impressive, but if you don't know what Dedicated Hosting is in the first place, these features probably don't matter much to you at all. When you purchase a Dedicated Server from A2 Hosting, you are getting all of the resources listed with the server plan of your choice. You do not share these resources with any other user or customer. The bandwidth, RAM and data transfer are for your use exclusively. With all of these resources at your disposal, you can expect your hosting service to be both highly reliable with top performance.
