VPS stands for Virtual Private Server, which is a virtualized server created by partitioning a physical server using virtualization technology into multiple distinct virtual servers. These virtual servers share resources from the original physical server while maintaining separate identities.
Introduction to VPS
What is VPS?
Firstly, let's clarify the definition of VPS - Virtual Private Server.
Tothost will break down this concept for you:
A server is a powerful machine that stores all the necessary files for your website.
Next, the virtual aspect: VPS utilizes virtualization technology to divide a physical server into multiple virtual servers. Imagine it as a physical device but operating as multiple distinct servers.
The term "private" holds its precise meaning. The virtual server is dedicated solely to you, ensuring you won't share RAM, CPU, or any data with other users.
In simple terms, VPS is like your personal computer in a virtualized environment.
The Definition of VPS
A VPS, also known as a Virtual Private Server, is a virtual machine that provides virtual server resources on a physical server, shared among various users. With VPS hosting service, you receive a dedicated server space with allocated resources, offering greater control and customization compared to shared hosting services.Google Cloud
Configuration Specifications of a VPS
This refers to the CPU's processing cores. A physical server possesses a certain number of cores, which are allocated to virtual servers. The higher the number of cores, the better the performance.
RAM plays the role of a type of main memory. For VPS, having a larger amount of RAM is better as it enables superior data access capabilities. This is because when using VPS, you'll need to utilize RAM to process multiple tasks, such as handling PHP code through PHP software, executing input-output queries for MySQL databases, along with small accompanying applications, and supporting read-write data operations. Therefore, this RAM specification is indeed of great significance.
Disk (Ổ cứng)
The hard drive (also known as disk) is used to store the operating system's installation files and all files related to the website's source code.
There are two main types of hard drives:
- HDD (Hard Disk Drive): This is the most common type of hard drive and is still widely used in many computers.
- SSD (Solid State Drive): Referred to as a solid-state drive, this type of drive is used to store data and offers access speeds up to 300 times faster than HDD. For instance, in a test scenario, an HDD might have an access speed of around 80MB/s, while an SSD can reach over 400MB/s.
Bandwidth is used to indicate the amount of data transmitted in one second. It is usually measured in megabits per second (Mbps) or gigabits per second (Gbps).
Users often encounter confusion between Bandwidth and Data Transfer.
Data Transfer indicates the total amount of data you can transmit over the network within a certain period.
It is calculated by aggregating all the traffic transmitted between the VPS server and the user, including data sent through web browsers, emails, FTP, SSH, or other applications.
Typically, a VPS may or may not have Data Transfer limitations, depending on the provider. With Tothost's provided VPS, Unlimited Data Transfer is offered.
Internet Protocol (IP) is the number of network addresses that the service provider will assign to you. Currently, VPS can use IPv4, IPv6, or both simultaneously.
How does a VPS work?
A server is a computer used by your web hosting service provider to store the necessary files and databases for your website. Whenever an online visitor wants to access your website, their browser sends a request to your server, and the server transfers the required files over the internet. VPS hosting provides you with a virtual server that simulates a physical server; however, in reality, this computer is shared among multiple users.
Using virtualization technology, your hosting service provider installs a virtual layer on top of the server's operating system (OS). This layer divides the server into partitions and allows each user to install their own operating system and software.
As a result, a Virtual Private Server (VPS) is both virtual and private because you have full control. It is isolated from other users at the OS level. In fact, VPS technology is similar to creating partitions on your computer when you want to run multiple operating systems (e.g., Windows and Linux) without needing to restart.
Using a VPS allows you to set up your website in a secure environment with guaranteed resources (memory, disk space, CPU cores, etc.) that you don't need to share with other users. With VPS hosting, you have high-level access similar to owning a dedicated server, but at a much lower cost.
Virtualization Technology for VPS
Currently, there are various virtualization technologies that offer specific features for VPS, but the most popular ones are KVM and VMware.
