We often hear about the concept of VPS – virtual server – in programming in general, and web development in particular. So, what exactly is VPS? What are their benefits and drawbacks? Let’s discover more about it today in the following brief article!

What is VPS?

VPS, or Virtual Private Server, is a type of virtual server established by partitioning a physical server into multiple virtual servers. To put it another way, it is a subcomputer placed within the physical server that has all of the configuration settings such as CPU, RAM, memory, and so on, as well as the operating system.

VPS virtual server is separated from physical server

Virtual private servers (VPS) use virtualization technology to segregate private server resources, avoiding sharing such resources with other users on the physical server. You have full administrator access to the server and can do whatever you want with it.

What is VPS used for?

VPS is the primary choice of website owners whose average visitors have exceeded the limit of shared hosting but do not require the massive resources of dedicated hosting. Hosting on a dedicated server. It is frequently used as a private server to host internet services, as a game server, to develop a commercial email system, or for any other service that demands a significant number of resources and high setup.

Pros and cons of VPS

If you’re still unsure whether a virtual private server is good for you, here are some important advantages and downsides to consider!

Advantage

VPS offers the following benefits due to virtualization technology’s ability to divide resources from other servers on the same physical server and ensure server configuration parameters:

• VPS hosting is more stable and secure than shared hosting.
• Avoid being consumed by other users.
• You have administrative privileges on the VPS.
• High levels of security and privacy.
• The website will not be affected if traffic unexpectedly spikes.
• When the website’s traffic spikes frequently, simply upgrade the hosting service plan from the provider without having to transfer data or servers.

Disadvantage

Despite their many benefits, virtual private servers have several limitations:

• The cost is higher than that of shared hosting.
• If the server configuration is incorrect, it can lead to security flaws.
• To operate VPS, users must be familiar with networks, computers, and operating systems.

How does a VPS virtual server work?

Even if you are still sharing a physical server with other customers, VPS provides the experience of a dedicated server.

Using virtualization technology, the web hosting company will construct a virtual layer on top of the server’s operating system (OS). This layer, which divides the server into discrete compartments with virtual walls, will allow each user to install their own operating system and software.

VPS is effectively a private server because it separates your files from other users at the operating system level. That means your website is in a secure container with assured server resources, including all memory, space, hard disk, CPU, and so on. You will not be required to share any resources with others.

Parameters to pay attention to when buying/renting VPS

Each Virtual Private Server has unique factors that influence the machine’s quality and price. As a result, before purchasing or renting a VPS, you should consider the following factors:

• RAM is a crucial component that determines a computer’s productivity. Virtual private server RAM currently ranges primarily from 512MB to 32GB; the larger the RAM, the greater the processing power and speed of the VPS. Different RAM memory will be required depending on the needs of the user. If you need to utilize a WordPress website, for example, 2GB of RAM or more can handle a high volume of visitors every day.
• Hard drive (Disk): This is the storage space for operating system files and virtual private server web source files. Disks will be divided into two types: HDD and SSD (semiconductor hard drive data access speed is many times faster than HDD). SSDs with rates of up to 2 GB/s are available in some VPSs. Of course, whatever you pay for, a virtual private server with an HDD will be less expensive than an SSD.
• The greatest quantity of data that can be transmitted between the user and the website in one second is referred to as bandwidth. There will be varied bandwidth limits depending on the VPS package; the higher the bandwidth, the more data can be transported, preventing disruption of the transmission line, meeting high traffic on websites.

As can be seen, Virtual Private Server is an excellent choice for people who require a data storage with the same traits and characteristics as a dedicated server but do not have the necessary resources.
