VPS (Virtual Private Server) - Description and Advantages
A VPS (or Virtual Private Server) is a type of service provided by cloud hosting companies to their clients. This type of cloud hosting provides great advantages to the users, and therefore it is no wonder that it is one of the most successful types of cloud services today.
How VPS servers work
VPS are virtual servers, created by a specific type of software called virtualization software. To do this, a cloud hosting company installs the virtualization software on a physical server, and then splits its resources into many smaller virtual servers, or VPS. Each VPS therefore has access to a portion of the computing power, disk space and memory from the original physical server.
There is a huge number of advantages of using VPS servers, let's just mention a few:
Cost. It is far cheaper to use a VPS. Instead of buying an expensive server machine and having to pay for internet bandwidth, electricity and maintenance, you can simply purchase a VPS, sometimes as low as $4...$5.
Geographical coverage. You can get one ore more VPS servers in datacenters across the world without any additional cost. Therefore, if you need to serve clients in remote locations, you can do that easily without having to pay more.
Maintenance. VPS servers are provided by the cloud hosting company which takes care of their maintenance, ensures enough power is available including redundant power connections and backup generators, so user experience is excellent. If anything goes wrong, the cloud hosting company takes care of it. This also applies to the precious network connections, that need to be fully available 24/7. It is to be said though that from the software standpoint, most VPS servers are maintained by the clients, the account owners that have purchased a VPS.
Fast and easy software deployment. Most cloud VPS companies offer a number of pre-built images that can be quickly loaded on a VPS server. You can choose operating system and additional perks, and have that installed in minutes on your server. No more hard work and time consumed – you can get that server up and running fast and easy!
Backup and Snapshots. With most cloud hosting companies, you can easily backup and restore your VPS via automatic backup features that are built-into your user account. This takes the worries off your head – if your server doesn't work correctly anymore or is infected, you can safely restore an earlier version from the backups. It is to be said that with most cloud hosting companies, backups and snapshots are optional paid services.
Redundant networking. The datacenters that host cloud VPS servers are connected to redundant internet connections. If one connection fails, there is always an additional connection that can take over the traffic until the primary connection is restored. This is obviously too expensive for a small company to do at their headquarters, and therefore the VPS provides an elegant and inexpensive solution.
Redundant Power. VPS servers reside in datacenters featured with backup generators – if the power goes down for any reason, the backup generators kick in and ensure the needed power is been fed to the VPS, and therefore there is no downtime. Again this is difficult and costly to do if you'd use your own physical servers instead.
There are other advantages of VPS servers; we have just mentioned above some of the most important ones. Nevertheless, this technology is helping thousands of users worldwide and will continue to be one of the most successful cloud hosting services for years to come.
