RAM

RAM is the main type of memory of computers. The more RAM is, the better the ability to retrieve is because when using VPS, you need more RAM to handle issues such as handling the PHP codes with the PHP software, handling import and export queries of database with MySQL, small bundled application, support read and write data, etc. so this parameter is very important.

Currently, most of the VPS services have the RAM from 512 MB to 16 GB. If you find any server hosting has RAM more than 16GB, it is Cloud VPS. And depending on the traffic to your website as well as the way optimizing VPS, you should choose the best RAM for yourself.

SWAP

SWAP is a virtual memory to save the old actions of handling if the RAM is overload. SWAP itself is a storage space on the hard drive rather than a stand-alone memory.

However, you can still create a swap on your VPS and it is recommended to create swap to make the server achieve the better performance.

Disk

A disk is simply understood as a hard disk (HDD), the storage space is used to save installation files of the operating system and the files of the website source code you saved on it.

CPU Core

In VPS packages, you will be selected from the category of 1 core to 6 cores in average.

Bandwidth/Transfer

You many have known what the bandwidth/transfer is when buying the host. The bandwidth is the traffic of data you are allow to transmit.

For example, if you have a file with 1GB of capacity on VPS, for every one person downloads, you will lose 1 GB of bandwidth, similar to other files such as image, CSS, JS, etc.

IP

Normally, if you buy many different IPs, the IP ranges will have a common class A and B. For instance: 192.168.1.1/192.168.1.2/192.168.1.3.

That is 6 basic parameters you should know when buying VPS, in which the parameters related to SWAP may not be shown to the outside price list, and you will choose the IP you want on the order website.

cPanel, DirectAdmin or Parallels Plesk?

All of them belong to a Webserver Control Panel for VPS or Dedicated Server. Its main function is to support your webserver configuration, creating small host packages or even supporting you to sell host.

The operating system of CentOS, Ubuntu, Debian, Windows Server, etc.

When purchasing VOS, they will ask you what the operating system you want to use. This is the important thing you should clearly understand also.

In which, if you use WordPress in particular or run the PHP website in general, you should choose Linux operating systems. You can choose the operating system of CentOS or Ubuntu because they are the two operating systems used by many people and it is easy for you to find many instruction articles.
