A virtual private server (VPS, also referred to as Virtual Dedicated Server or VDS) is a method of splitting a server. Each virtual server can run its own full-fledged operating system, and each server can be independently rebooted.(Via Wikipedia)

Benefits of VPS

The best things about VPS are its dedicated-server-alike features and affordable pricing.

Isolation Each private server has its unique file system and gets a  guaranteed fraction of the server’s disk space, CPU power, bandwidth, and memory. Hence, a website hosted on a VPS runs on an isolated environment where its performance will not be affected by other websites. Also, a VPS does not share web application and services with other websites thus it eliminates the risk of downtime or hacks due to other’s mistakes.

Customization VPS users get full root access. This allows server customization – you get to install your own software/application and manage your server as you would on a dedicated server.

Affordable VPS is cheap. You’ll get features like dedicated servers but cost a lot more cheaper (in most of the case, 50% less) than a dedicated hosting plan. You can compare the pricing different between a dedicated server and VPS hosting below.

What to look for when choosing a VPS?

Besides pricing, there are a few other important points that you should look at when it comes to VPS shopping. Choosing a VPS provider that’s easy to communicate is very important. A web host who’s willing to listen and accommodate your specific needs is very important.

Also, getting a flexible VPS provider that allows hardware customization is very important. Avoid web hosts who offer only ’standard’ plans as this will creates troubles in your future upgrades. Each website has different needs, maybe you need lower CPU speeds, or larger storage, or less bandwidth, or more RAM – you’ll never know what kind of upgrades you need in the future. Do you want to upgrade your entire hosting plan everytime you need a minor upgrades? No, of course. If all you need is just some extra RAM, why should you upgrade the entire hosting plan and pay for all the unnecessary storage and bandwidth?

Is VPS right for you?

When your website has outgrown your shared hosting plan and you couldn’t afford the price of a dedicated server, then VPS is your answer. Most webmasters see VPS as the stepping stone to dedicated or self-managed private server.

Buy VPS, stand-alone server will be related to a problem is that service provider’s network bandwidth.

Confusing several concepts: Mbps, Mb / s, MB / s.

1, we often hear such and such a server, IDC provides exclusive access to bandwidth is 10M or 100M share of the class of data. Here, 10M, 100M in the end what is the idea?

The so-called 10M bandwidth, I was referring to 10Mbps (megabits), which is 1.25MB / s, but this is only a theoretical speed, in fact, but also minus wear and tear. 10M bandwidth according to this argument the fastest download speed is 1.25MB / s, 100M bandwidth of the fastest download speed is 12.5MB / s.

2, in the above we have come into contact with the MB / s, which MB / s and Mb / s What is the difference where? 阅读全文 »

After the Xen server installed with the Xen virtual machine users increase, the need to regularly look at the Xen server (host) state, and various virtual machine (guest) of the operation, taking up system resources. There are already lots of monitoring tools for Xen can be used, but do not advocate the abuse VPSee third-party tools, will increase the burden on dom0, as well as a security risk, keep it simple (KISS), as far as possible with a simple tool to do things (do not understand why someone would write a note, still use Word, Notepad you can easily get to ah, this again makes me think of Vi vs IDE ~ ~). VPSee of several Xen servers are only used to provide a virtual single service, dom0 only to provide hardware abstraction, a hypervisor layer to a domU, so it should keep dom0 streamlined, but also for safety, do not advocate the dom0 to install and run any non – the necessary software. To monitor the Xen server, then the best is to use better command-line tool that comes with Xen. 阅读全文 »

Now labs are equipped with a Taiwan Masters, and a laptop PC, but only to Honours with a Taiwan PC, 1 machine very easy to do the project, development is often used in multi-system, such as some people do is to VoIP phones related projects, mobile client interface to Windows platform to do, VoIP server to use to Linux, so use a Linux virtual machine virtual out, if they are running on a single physical machine will be very slow. Now configure the PC to the Honours only 1G of memory, if you are running Windows + mobile emulator + Elipse IDE (needs Java) + VMware (VMware on a rerun a Linux + Asterisk + MySQL), and then open a client of incoming mail, open a few a browser, viewing the information would be very difficult.

In other countries, especially the United States such copyrights very strong country, more than 90% of the servers are Linux. Why? Sentence: Linux free, stable, good performance and low cost!

In the United States, 80% of the programmers and technicians are based on the Linux platform.Only 20% of the technicians is a Windows platform, so the cost of expensive technical manpower.
And on the Windows operating system itself, Microsoft is genuine to the monthly charge exorbitant licensing fees. This part of the money has undoubtedly passed on to the consumers.
Software costs: Windows genuine software, the system almost all of money, but most of the software under the Linux system are free of charge, which also led to the cost gap.
Thirdly, since the majority of foreign owners are using Linux vps, then the Windows VPS on a relatively small market, IDC is necessary to invest more to maintain its cost.
To sum up, in the same room, the same configuration context, Widnows VPS on the much more expensive than the Linux VPS. 阅读全文 »
