Hosting selection is one of the most important steps in the first stages of website creation. Novice webmasters tend to be interested in inexpensive offers because their budget is limited. They strive to choose a hosting that would provide the required minimum of features without overpaying for unused resources. Therefore, for a young site with low traffic, they usually choose a cheap virtual (shared) hosting.
Price is an important advantage on a limited budget, but there are a number of pitfalls that inevitably come with regular hosting. If the traffic rises sharply, or a project with high peak loads is located on the same server, this can lead to interruptions in the site's work. For commercial projects, this is unacceptable even at the initial stage, so it is better to immediately choose a VPS hosting that provides guaranteed resources for a comparable price. Hosting company Adminvps told what is the difference between VPS hosting and others.

What is VPS
A virtual server or VPS is a software-emulated analogue of a physical server. It has its own operating system, its own set of settings and software. For the user, VPS hosting looks the same as a 'hardware' server and provides similar capabilities. However, some hardware resources are shared, since several virtual ones are usually running on one physical server.
The VPS / VDS administrator has full root access and can execute any command, install the required program or change the configuration. At the same time, he always has at his disposal the amount of memory, processor cores, disk space allocated by the provider, as well as an Internet channel of a certain width. Thus, VPS hosting provides the user with virtually the same level of control, independence and security as a regular physical server. At the same time, it is much cheaper for the price (albeit somewhat more expensive than regular hosting).
Advantages and Disadvantages of VPS Hosting
A virtual server offers the user a 'golden mean' between shared hosting and a physical dedicated server. It provides high and stable performance at an affordable price. The main difference from conventional hosting is the lack of influence from the 'neighbors'. At any time of the day, VPS hosting provides your projects with the same amount of computing resources.
Comparing shared hosting, VPS and Dedicated server, the following pros and cons can be distinguished:
- Shared hosting: One hosting server hosts many different sites.
- pluses: quick start, simple operation, low price;
- cons: minimal control capabilities, low productivity, depending on the time of day and the workload of neighboring projects.
- VPS hosting: the server is virtually divided into parts and one part is dedicated to your projects.
- pluses: secure environment, root access, configuration flexibility, stable performance;
- cons: VDS is somewhat more expensive than shared hosting.
- Dedicated: The entire server is dedicated to your projects.
- pros: maximum level of control, safety and productivity;
- cons: very high price, more complex and expensive service.
What projects do you need
A non-commercial site with low traffic can work fairly well on regular hosting. But as traffic grows, productivity becomes insufficient. Pages take longer to load, and sometimes the site may even 'crash' – becoming unavailable for a few minutes. In some cases, you may receive a notification from the hoster that the project has already reached the monthly resource limit. In this case, switching to VPS hosting will be the best option, providing stable performance and constant website availability.
How to manage websites on VPS
Management of web resources located on a VPS / VDS is carried out in the same way as on a regular hosting. Most providers provide customers with one of the popular control panels (ISPmanager, cPanel, Plesk, and others) for free. Some hosters also offer their own panels, which look about the same for both hosting and VDS.
The most popular panel on Runet is ISPmanager 5 Lite. This panel has a convenient Russian-language interface with competent terminology without errors (which are often found in other products). With its help, you can perform in a visual mode all the actions necessary in the VPS administration process (adding and editing users, managing sites, databases, email and other resources).
How to choose
The decision to switch to VPS hosting is only half the battle. Now you have to decide on the provider, since this market is overflowing with offers, and choosing the most interesting is not so easy. Determining the optimal VDS tariff is much more difficult than choosing a shared hosting, since you need to take into account more nuances. Let's consider the main factors that should be given the most close attention.
- Administration. Regular hosting is located on a shared server, which is managed by the provider's staff. You will have to monitor the performance of the VPS yourself, which is not always convenient. Therefore, it is better to immediately choose a tariff with administration (managed). In this case, the work of the server will be controlled by a professional system administrator. Choosing VPS-hosting with administration, you get all the advantages of a virtual server without having to independently control its operation 24 hours a day.
- Operating system. Most hosters offer their customers a choice of a server operating system Windows Server and several distributions Linux. Windows has no significant advantages, but sometimes it is necessary for the operation of certain software (for example, ASP.NET). If you do not use such software products, VDS with Linux will be the best choice for you (you can choose a specific distribution kit according to your taste and experience, since they all provide the necessary functionality).
- Server equipment. Most providers offering VPS / VDS services are in no hurry to share information about what physical hardware virtual machines are running on. But this question is worth asking before choosing a hosting or virtual server. It is important to know not only the amount of RAM, CPU cores and hard disk space, but also the class of this equipment. It is desirable that the servers are equipped with the latest generation processors, fast DDR4 memory and high-speed SSD drives. A provider using such hardware certainly does not hesitate to describe the configuration of its servers.
- Reliability. The uninterrupted operation and availability of your VPS directly depends on the class of the data center in which the provider's equipment is installed. An important indicator is availability, which can be at 99.8% (Tier II) or 99.98% (Tier III). It would seem that the difference is small, but the cost of infrastructure is much higher, which means that services are also much more expensive. For reliable operation of the site, it is recommended to rent VPS hosting in a data center with a class of at least Tier III.
- Equipment redundancy. Reserving resources can significantly improve the reliability and stability of VDS. For example, if the data center has its own emergency power supply system (UPS and diesel generators with a supply of fuel), it is not afraid of power outages. Reservation of communication channels is also important. It should also be possible to quickly restart the VDS in case of failure of the equipment on which it works.
- Channel width and traffic limit. The conditions for using the Internet channel are not always transparent. Many providers limit the bandwidth or charge for the traffic used by your VDS in excess of a certain limit. Such issues should be clarified in advance so that they do not interfere with the operation of the server or raise the price bar beyond the planned one.
- The quality of technical support. Even a well-debugged system can fail, so not only reliability is important, but also the speed of troubleshooting. Good tech support is the most important factor to consider when choosing the best hosting or VDS. You can judge the competence of the technical support of the selected provider by the reviews, as well as by your own communication experience, by asking a couple of questions at the beginning of cooperation.
- Price policy. Of course, the price is always one of the main factors when choosing a hosting. However, it is important to understand that VPS hosting running on a modern server in a high-level data center will cost several times more than a budget counterpart with the same characteristics. Good support also contributes to the price, as it employs qualified, highly paid administrators.
- Geographic location of the data center. Today there are no restrictions on choosing hosting or VDS in another country or even on another continent. But it's best to always target your target audience. If the server is located in a different country, it will inevitably add a few tens of milliseconds to the load time.
- Possibility to rent additional IP addresses. Sometimes you need to connect an additional IP address to the server. For example, if you need to install SSL certificates for several sites on one VPS hosting (older browsers have compatibility problems if there are several sites with SSL encryption on the same IP). Sometimes it is required to host the administration panel, database or subdomain in another language on a separate IP-address. Therefore, it is advisable to make sure in advance that the selected tariff implies connecting additional IP to VDS upon request.
Speed and stability are important characteristics that determine the success of any site, especially if it is a commercial project. VPS hosting provides high speed of work, while its price is much lower than that of a dedicated server. There are many interesting offers on the market today, so you need to be careful about choosing a VPS, carefully weighing all the factors.
The most important parameter is the amount of RAM. If you need VDS to run one site on PHP + MySQL, then the amount of RAM should be at least 512 MB. This is enough for a site with average traffic, and in any case you will feel an increase in performance when switching from a regular shared hosting. The type of drives used is also important. HDDs are already outdated, so you should choose a VPS with SSD. Such servers have a speed of work with the disk subsystem tens and hundreds of times higher, which significantly affects the overall performance.
In order to rent a virtual server of suitable capacity and at the same time not overpay, you must determine the requirements in advance. Most providers allow to increase the performance of VDS during operation by adding memory, processor cores or disk space. But having calculated the optimal configuration right away, it will be easier to choose the most suitable tariff.
