What is VPS and why is it needed
VPS (decryption in English: Virtual Private Server) is a service for leasing a virtual dedicated server. Let’s explain in simple terms what this means. Imagine that you want to create an online store that will have a lot of products, filters and pages. The resources of regular shared hosting are not enough for you: you want to have your own IP address, install the necessary software, and do all the settings yourself. Then the link https://deltahost.com/vps.html to a virtual dedicated server comes to the rescue.
The principle of operation of the VPS / VDS server
On a regular physical server, there can be many virtual servers – VPS. They emulate the operation of a physical server, and clients are given full control access. VDS work using virtualization (a technology that provides isolation of computing processes running on a single resource).
• KVM – virtualization, which makes it possible to create an absolute virtual analogue of a physical server.
• OpenVZ – operating system level virtualization. The technology is based on Linux and allows you to create separate copies of the desired Linux distribution: Debian, CentOS, Ubuntu.
Why do you need a VDS server
1. For websites. Online stores, large forums, corporate sites with a large assortment – for all these sites, you can safely order VPS hosting.
2. For development and testing. Designing, developing, testing, and deploying software products typically requires the work of an entire team of specialists. Virtual dedicated servers help the team in their work: they are flexible in settings, it is possible to connect at any time of the day or night, and if something does not go according to plan, the system can always be rolled back.
3. For VPN servers. For example, our VDS can be used to create a VPN server, however TUN/TAP virtual interfaces are deactivated by default. To enable interfaces, you must send a request through the “List of Requests” menu in the “Support Center” section of the billing panel.
4. For game servers. Shared hosting does not always support the software required to create a game server, and on a VPS you can install it yourself.
5. For mail servers. A virtual dedicated server can be an excellent tool for working with well-known email clients (Outlook, The Bat, Thunderbird). A mail server based on VDS will provide full controllability and safety of users’ personal data.
Benefits of VDS
• Cost savings. With the help of VPS technology, you can not rent an entire physical server. VDS services are several times cheaper.
• Isolation from “neighbors”. VPS operate autonomously from other virtual servers, of which there are several on a physical server.
• Reliability. It is provided by personal hardware resources. Each VDS is allocated certain amounts of RAM and other capacities.
• Root access. VDS owners have the right to perform all without operations. They can install the necessary software and make other settings.
• Own IP address.
Disadvantages of VDS
• Although the price is cheaper than for renting a dedicated server, it is still a little more expensive than for a regular shared hosting.
• This is not a full-fledged server, but only a virtual one. This must be taken into account and understood. For highly loaded projects, it is still preferable to use Dedicated Server.
• Need administrative skills. Without certain knowledge, setting up a VPS on your own will not work.
Conclusion
Thus, if your project has “outgrown” virtual hosting, then the next step in its development will be just a VPS/VDS server. It is perfect for online stores with a growing assortment, large information portals, and projects with high traffic. Choose a virtual server based on the complexity of the project and the required resources. More traffic and good luck!
