What is a Virtual Private Server?
A virtual private server (VPS), also known as a virtual dedicated server (VDS) is process of splitting up a regular physical server computer into several additional servers. The additional servers have the ability to run on each of their own machines. In addition, each server can run a separate operating system and has the capability of being individually rebooted as needed.
The private virtual servers have the ability to optionally connect shared hosting services for the web and other hosting services. This gives each server independence in relation to other customers of the same VPS service in terms of software. However, it costs significantly less than a regular physical dedicated server. Due to the fact that a VPS runs a different copy of an operating system, people, primarily customers, have increased access to the operating system. The operating system, for instance, can install almost any software that that person can run on the operating server.
Unfortunately, some software does not have desirable capabilities within the virtualized environment. Some programs that people have historically had many problems with are firewalls, anti-virus programs, and surprisingly, the virtual servers. Depending on the VPS that a person chooses, there will be other restrictions in addition to the ones mentioned. However, most VPS are very relaxed when compared to sister servers in shared hosting environments. Another drawback is when many clients are put on the same virtualization program, those clients who are running on an individual, single machine will experience slower processor time, decreased RAM and a decrease in available and usable disk space.
Because a VPS is used in isolation, they have come to be known as breeding-grounds for potentially insecure public servicing or forced update testing by others. To use an example, a physical server will often times have two virtual private servers running at the same time: one that is hosting the production level, or living website, and another server that will store a copy of the website. Around the time that necessary updates are available for crucial parts of software, the updates have the option to undergo testing within the second VPS, which allows further detailed tests to be undergone without the requirement of several additional physical servers.
Not only is shared hosting a great option for any small website developers out there, but it is also much cheaper than other possibilities. Additionally, if you are running a small website that doesn’t demand large amounts of memory or storage, then you will also skirt the disadvantages of a VPS. If are in search of base level access to your server, then VPS is also the right server for you. However, if you decide on a VPS be sure you understand what you’re doing. A VPS gives you a lot of freedom, which is great if you understand exactly what you’re doing and why. For instance, you could delete the wrong files, or not make yous system as secure as you would like it, and therefore your files will be vulnerable. On the other hand, the multiple systems give you freedom to explore the world wide web completely new way.

What You Need in Dedicated Server Hosting Pt. 1
Once your traffic starts bursting through the seams of a shared server, it’s definitely time to make a serious upgrade. When this is the case, you just may need a dedicated server. As with any type of web hosting, there are several factors that must be considered when opting for dedicated hosting. You’ll have to go over the basics such as researching and evaluating a company to make sure they can be counted on. Hopefully, everyone realizes that you must comb a web host in and out before signing with them. This is something that simply can’t be stressed enough. Here are some more specifics for your journey in finding dedicated hosting:
Server Hardware
Let’s start with the backbone of dedicated hosting – the server. I’m sure you’ve heard about how dedicated hosting is more robust and flexible than its shared counterpart – for the most part, that’s all true. You should still read up on the actual hardware to find out exactly what you’re getting. For example, you’ve got computers manufactured by Dell, Intel and other companies. Then you’ve got your single-core, dual-core and quad-core variations. Dedicated servers are designed for businesses at varying levels so it’s best to pick a package with enough power support your existing needs and allow for scalability as well.
Server Resources
Some web hosting companies and article writers can make a dedicated server appear so amazing that you might assume there is nothing this super machine can’t do. You can bring yourself down to reality after coming to understand that it is simply a computer that has its limits. Even though you are not scraping and fighting for resources with other customers, the vitals can be exceeded. I’m not going to get into all the unlimited stuff right now – just know that your dedicated server will need an adequate supply of disk space to suit your plans. The same goes for bandwidth, data transfer or whatever you wanna call it. Sure, most web hosting companies will let you upgrade but that comes with additional fees. Keep in mind that you’re not paying a month for hosting. Why not get something you can stick with for a while? Definitely beats paying for costly upgrades every other month.
Maximum Uptime
Uptime is another critical aspect that I hope resonates within everyone’s mind. This is even more important when it comes to dedicated hosting. After all, you’re paying a lot more money so you wanna get the best performance possible. For the most part, dedicated server providers will advertise the same uptime guarantee as a conventional shared host – 99.9%. However, it isn’t uncommon to find a company that offers a 100% guarantee for uptime and service level agreements. In my opinion, 100% is always questionable but it does sound good. The key is to find a dedicated host that offers a maximum uptime and can provide some evidence of how they go about ensuring that guarantee. If this is the type of hosting arrangement you need, you are probably running mission-critical operations. In this case, excessive downtime is something you simply can’t afford.
Who I am kidding? I barely scratched the surface on this dedicated hosting stuff. Follow me over to part two of What You Need in Dedicated Server Hosting.
