I. VPS exactly mean?
VPS is an acronym of the phrase V irtual P rivate S erver (virtual private server). A VPS is like Shared Hosting, VPS that will have to be placed on the same physical server. So it's different than Shared Hosting at a certain point that the higher prices that serve the larger web?
Model comparisons between VPS and Shared Hosting
The reason is that for Shared Hosting, the hosting packages that are shared resources are identified from a physical server resources allowing very low.
For example, I have a server with 6 cores / 12 threads, but will create 3 different VPS parameters is 2 cores / 4 threads and in which their VPS package will create 50 Shared Hosting packages commonly used resources from 2 cores / 4 threads this. That is with 2 cores / 4 threads, you would divide the Shared Hosting packages and configuration resources from this will be shared with each other, the less they spend spend spend to much but not too much to handle allows the two cores / 4 threads.
As for VPS is different, each VPS possess RAM parameters are completely separate and you can use all the resources are allocated. VPS instance you have 2GB of RAM, 2 cores, 2 CPUs, then you will absolutely use all the resources that are not shared by other websites because each VPS is a virtual server system based on an independent physical server.
That's why when using the VPS, your website will not be overloaded and slow due tosecurity better.
II. These parameters need to know when buying VPS
When you buy any VPS where you select the parameters are as follows and the prices of VPS will depend on such parameters. These parameters are the computer industry specifications so you can easily make people understand because IT knows all because the server itself is also a computer, it's just that more buffalo.
2.1) RAM
In the computer, the RAM is the memory type, if your VPS as much RAM, the ability to access data as possible because when using VPS, you will need RAM so it handles issues such as handling PHP scripts PHP software, entry and processing of database queries with MySQL, small applications bundled, supports read write data ... so this is very important parameter.
Currently most of the VPS service will allow you to select the RAM from 512MB to 16GB (if you see any more than 16GB RAM VPS, it is Cloud VPS) and depending on the traffic to your website as well as at given VPS, you will need more RAM or less.
With regard to the need to use WordPress, you need at least 1GB of RAM to be able to be used comfortably, if you have a few cases, they can be distinctly VPS 512MB type and optimized for it, you can run well with the amount access to approximately 5,000 / day and 100 users online at the same time.
2.2) SWAP
Although you probably do not use their resources but also SWAP please explain if you have any questions.
SWAP you is sort of a virtual memory to save the old processor action if your RAM is full (overload), SWAP is itself a storage space on the hard drive rather than a independent memory.
But the VPS does not also support the SWAP memory which only supports Xen VPS SWAP. See below to learn Xen VPS is.
2.3) Disk
Disk or simply learn the hard drive (HDD) storage space will be used to save the file to install the operating system and files of your website source code stored on it.
The drive is now divided into 2 categories:
- HDD (Hard Disk Drive) is the most common type of drive that you use so long on that computer.
- SSD (Solid State Drive): SSD or you can also hear translated into Vietnamese assolid-state drive , a hard drive to store data, but it will have the data access speed faster than a HDD up to 300 times, this alone is not derived from the theory that it has conducted some tests, HDD access speed is about 80MB / s but the SSD speeds of over 400mb / s.
Often VPS type SSD will be priced higher than an HDD.
2.4) CPU Core
Core means of CPU cores. A Dedicated Server has a certain number of core and it will be distributed to the VPS. Usually, the higher the number of core data processing capabilities as well.
In VPS packages, on average you will be selected from type 1 core and 3 cores.
2.5) Bandwidth / Transfer
These two words have the same meaning as bandwidth . Bandwidth is what you make when purchasing hosts already know but I would like to say again that the traffic bandwidth means that you are allowed to transmit data to go.
For example, you have one 1GB file on the VPS as every one who download you will lose 1GB of bandwidth, similar to other types of files such as images, CSS, JS, ....
2.6) IP
IP (Internet Protocol) if thoroughly explained the concept of the long process. Here I would like to sum up the number of IP addresses you they will give you. The IP address range will be randomly selected supplier for you.
Usually, if you choose to buy more different IP ranges, then it will have the same IP class A and B. For example: 192.168.1.1/192.168.1.2/192.168.1.3.
That's 6 basic parameters that you need to know when buying VPS, in which parameters can SWAP few vendors will not show outward price, and you will be selected IP number to purchase at ordering.
2.7) cPanel, DirectAdmin or Parallels Plesk?
3 Although this is not really necessary if you use VPS for their private purposes but will clearly explain to you see you know what I should choose.
All 3 this is a Webserver Control Panel VPS or Dedicated Server for. Its main function is to support your webserver configuration, creating small packages or even host can serve you with the sale host.
Both Webserver Control Panel 3 above are as kind and if you choose to pay it as rent VPS, you will have to pay extra, prices range from $ 8 to $ 15 per month. but besides that there are many kinds of free but think you do not need to know it in a hurry, you just need to know what Webserver Control Panel only.
What is cPanel?
cPanel is a control panel Webserver best and most popular in the present time. If you have used through the Shared Hosting packages are probably already knew through the admin panel cPanel X, which is a function of the cPanel Control Panel.
WHM - Admin Area for management of software and cPanel Reseller
CPanel interface for the host packets generated by WHM
DirectAdmin is like?
The function is similar to cPanel but fewer features and less common, in return, the control panel is priced cheaper than cPanel.
Admin panel for management of DirectAdmin
Parallels Pleks is like?
The cPanel and DirectAdmin, like the other, but it only supports Windows VPS and Linux VPS.
Admin Admin panel of Parallels Plesk
It is the third type of control panel you will often occur at the service option in addition to the purchase VPS.
2.8) Operating System CentOS, Ubuntu, Debian, Windows Server, ...
When purchasing VPS they will ask you wish to use any operating system, this is an important issue that you should understand.
Most VPS services will provide support for the following operating systems:
- CentOS (Linux)
- Ubuntu (Linux)
- Debian (Linux)
- Fedora (Linux)
- Windows Server (Windows)
In particular, if you use WordPress, then select the type of operating system Linux. If you are new then select Centos VPS fundamental because in this series, I will guide users on CentOS because it's popular.
Later we will have more tutorial for the Ubuntu operating system for those who need to learn.
III. Un Managed VPS and Managed VPS
When conducting lease VPS, you need to understand your VPS provider to hire Unmanaged VPS and Managed kind VPS to avoid misunderstandings later and accidentally poured their innocence.
Furthermore, when you see the price of VPS services, there are areas where prices are very high, which is also where the price is very low, the main reason is the VPS managed or unmanaged VPS.
3.1) What is Managed VPS?
Managed VPS type of service that is provided to the customer together with VPS management service. Administration services here include installation / VPS advice about everything that customers need, as well as optimal performance and security for VPS.
Often Managed VPS with high prices for the VPS management is not easy, suitable for those who do not have many skills, but administrators need to use VPS VPS.
There are also a number of vendors they are not priced VPS administrator in brackets show the outside but will have the option VPS management service when ordering conduct.
Some VPS providers Managed typical
- Knownhost
- Liquidweb
- MediaTemplate
- Managed VPS A2Hosting
- InmotionHostin g
3.2) What is Unmanaged VPS?
Unmanaged VPS services that are not included in VPS VPS management for customers, but they only ensure your VPS without downtime or other causes stem from the main server.
With this service, all work as a webserver, configuration, software installation, security, ... all you have to do yourself. And you also bear responsibility for their settings.
Unmanaged VPS will be priced quite cheap, sometimes cheaper than double Managed VPS services but you should only use if they have no knowledge of VPS or at least understand it. If you follow the series Learn to use basic VPS, you should use Unmanaged VPS for free to do what I love. Managed VPS rather buy it make you have not read this series: D.
Some Unmanaged VPS providers typically:
- BudgetVM (But can advise your enthusiasm, support faster)
- DigitalOcean (Cloud VPS)
- Linode (VPS Cloud)
- A2Hosting Unmanaged VPS
- Online.Net
IV. Xen and OpenVZ VPS VPS
What you can not see them split up in a number of VPS providers, but some is divided into two separate VPS packages together, so Xen OpenVZ is what is what? It can affect your website or not? Let her learn Scorpions.
The theory of the 2 techniques this technology, so I would not here yet because it is not really necessary for you to understand right now, but I only speak through the use of its performance only.
4.1) What is Xen VPS?
Xen VPS is a virtual server technology that will let your VPS use the full resources of the VPS package that you are renting. For example, if you rent a VPS with 1GB RAM, 2 cores, you will be using the right amount of resources that are not shared by other VPS packages on the same server.
Xen VPS packages will usually accompanied by 1 SWAP option as I said in the beginning.
So Xen VPS package price is usually higher than OpenVZ.
4.2) What is OpenVZ VPS?
It is also a virtual server technology, but the differences are going to allow VPS packages on the same server resources supporting each other. For example, if you have 1GB of RAM and 2 cores but use your VPS will not use up the amount of resources that will complement the CPU resources for other VPS packages on the same server.
In terms of comparison, Xen OpenVZ is faster and better but the OpenVZ and Xen have better resources easily upgraded without rebooting the VPS.
V. Prepare what to buy VPS?
Just like buying hosting, VPS you need to buy some stuff prepared as follows:
- Visa Card or PayPal
- The two sides of the ID card scanner and scan the 2 sides of the card you used to pay. In case they need additional photos of bill payment, just taking a sheet of paper stating your address attached red wood is oke, but this is rare.
If you are a beginner, I recommend using Visa Card, you can see how to apply for Visa cards at ACB according to this article .
Behavior. Where to buy good VPS?
You can buy any VPS any where to learn in this series because using the same VPS. If you want to buy according to your suggestion, I would like to introduce some VPS providers that international good price also affordable.
BudgetVM (Unmanaged)
- Lowest price : $ 25 / year.
- The number of datacenter: 2 (USA)
- Managed Services : Yes, but only for cPanel.
- Reinstall the operating system : Yes
- KVM : Yes
- Refund : No
As a leading provider Unmanaged VPS now with these attractive prices. Only $ 4 / month as you've got an OpenVZ VPS with 1GB RAM, 1 CPU. If you need better configuration, you can try their VPS services SSD configuration better CPU, SSD storage is abundant with the cheapest prices.
But assuming that the policy cheaper but customer support is very good here, and the support of their technical staff can advise you on the technical issues and guidelines for you to do, because they do not offer VPS management service.
Thach current VPS is using 2 SSD and 1 Dual Core Dedicated Server at this, very satisfied.
DigitalOcean (Unmanaged - Cloud VPS)
- Lowest price : $ 5 / month
- The number of datacenter : 5 (2 American, 1 Singaporean, one Dutch, one British)
- Managed Services : No
- Reinstall the operating system : Yes

Cloud Hosting is only one computer network technology, there is still nature VPS VPS so you do not need to think twice about their VPS Cloud notes. Cloud VPS in DigitalOcean priced quite cheap, only $ 5 / month for 512MB RAM and support packages Singapore server.
Furthermore, an advantage of Cloud VPS service that you are free to create as many custom VPS, just the money available in the account and it will take but a day. When not in use anymore, then Destroy it as you do not spend any more money. What forms of payment are loaded credits to the account.
However, there is a drawback in DigitalOcean you need to know is that they are very or maintenance of the server system so sometimes your VPS will not be on.
VPS.NET (Unmanaged - Cloud VPS)
