VPS Hosting - What It Is And How It Works

If you have experience with web hosting, you know that web hosting shares the performance of the environment (servers) with other web hosts. In other words, web hosting does not have defined performance (memory and processor), but VPS (Virtual Private Server) has dedicated performance. You only share IOPS (storage read/write) and part processors.

With VPS you are buying clear performance, you get a virtual server where you have the freedom to choose the software you install on your VPS. At the same time, with this freedom, you have to set up and install the installed application yourself and update it. Hosting companies offer a free installation of the operating system package and hosting applications called "LAMP". Above this package is still installed a control panel for web hosting services, where you already set up individual web hosting, add domains and emails.

Configure and manage VPS hosting

One of the benefits of openvz vps hostingis an individual configuration. Most hosting companies offer free VPS installation of a popular LAMP package (Linux, Apache, MySQL and PHP). Just because you install the operating system (Linux), the Apache server, MySQL database, and scripts (PHP) for yourself, you can configure it according to your own needs. The other side of the matter is that VPS hosting requires knowledge of the Linux environment to set, secure, and update it.

If you have a VPS with an installed LAMP package, you still need a web hosting control or "control panel". This panel will create an environment where you can activate domains, set up your own web hosting accounts, emails, and databases. The most known control panels for web hosting are cPanel, Plesk and ISPConfig. Last but not least, you need to highlight the security of the entire LAMP environment, which you also solve yourself.

If you do not want to resolve this issue , I recommend that you get a "Managed VPS" or a more commonly used VMS (Virtual Managed Server) name. Here is the hosting company hosting the installation and operation of VPS hosting.

VPS Hosting Performance - RAM, CPU & STORAGE

VPS performance consists of a processor (CPU or vCPU), processor performance is reported at core speed (e.g., 1GHz) or processor thread count. The second and most important part of VPS hosting is RAM. The last part is the storage "storage", which indicates the reserved disk space on the server, or better, the SAN is an external storage system. Storage can be built on three types of SATA, SAS and SSD drives. Each disk has a different performance that we measure in the so-called IOPS (Input/Output operation per second), ie how much it writes/reads the data in one second. Here's a great way to see why SSD drives:

SATA (7200 rpm) has ~ 75-100 IOPS
SAS (15,000 rpm) has ~ 175-210 IOPS
The SSD has ~ 3300 to hundreds of IOPS by manufacturer and interface type

You can see that SSDs are many times faster, but also more expensive. SSD drives are often required where there is a lot of entries and readings at one point. Most commonly, SSDs are used for database servers.

The advantage of VPS hosting is the fact that you can upload virtually any application on your virtual server and run any services. With VPS hosting, the entire server looks like a dedicated server for you, including your IP address, operating system, and management. The virtual server is also much cheaper than the dedicated server. VPS hosting also has good connectivity and you can access the server directly.
