A service where the user is provided with a virtual server with maximum privileges. VDS or VPS emulates the work of a real physical server - there is root access, it is possible to install your own operating systems and software. A single physical server usually hosts several independent virtual servers.
What is the difference between VDS and VPS
There is an opinion that the terms denote virtual servers with different types of virtualization: VPS stands for virtualization at the operating system level, VDS stands for hardware virtualization. In fact, both terms appeared and developed in parallel, and mean the same: a virtual dedicated server running on top of a physical one.
We use the term VDS (Virtual Dedicated Server) because we believe that it more clearly reflects the essence of the service provided.
Principle and features of a virtual dedicated server
By the principle of operation and features of the functioning of a virtual dedicated server not much different from a physical server... It has no restrictions on the number of hosted sites, databases, domain zones, ssh-ftp-email-users, and its owner-administrator has the right to work with files, install applications and perform other operations, as on a real full-fledged server. Each virtual server on our hosting has own IP address that is not shared with anyone else. Additional IP addresses can be ordered if required.
A virtual server works independently of others located on the same host machine. This means that the failure of one server does not affect the functioning of the "neighbors".
Unlike ordinary virtual (shared) hosting, DDoS protection technologies are available on a virtual server, and data safety is guaranteed by the ability to create a backup copy.
Comparison of VDS / VPS with shared hosting
pros
- Full control: the owner of a virtual dedicated server gets root (for Unix) or Administrator (for Windows) access rights, and can fine-tune the server to fit the needs of a particular project up to installing the necessary software and changing the operating system.
- Minimum restrictions: the number of created sites, databases, domain zones, ssh-ftp-email-users is limited only by server resources.
- Independence: virtual servers “neighbors” on the host machine work in isolation and do not “pull” resources from each other, and also use separate IP addresses, while on ordinary virtual hosting several sites often use the same IP address.
Minuses using VDS / VPS in comparison with shared hosting:
- Price: The cost of renting a virtual dedicated server is usually significantly higher than the cost of shared hosting. But we offer comparable rates.
- The need for administration: the virtual server needs to be administered as a physical one, therefore the user requires certain knowledge and skills in this area. The control panel makes it easier to perform typical tasks: for our clients we offer the ISPmanager 5 Lite panel.
Comparison of VDS / VPS with a physical dedicated server
pros using VDS / VPS in comparison with a dedicated server:
- Low cost: Renting a virtual dedicated server is much cheaper for the user than renting a physical server comparable in capacity. At the same time, the performance of VDS / VPS may even be higher (see our research)
- Simple scalability: It is very easy for a virtual server to add more capacity in the form of additional RAM, processor cores or hard disk space.
Minuses using a VDS / VPS server versus a dedicated server:
- Common disk system and communication channel: all virtual servers running on one host machine, subject to the sharing of basic resources, use one disk system for all and a common high-speed communication channel. This means that some users may abuse resources and interfere with other clients.
We use an automated system that finds these users. Measures from warning to shutting down VDS are applied to violators.
Features of virtualization technologies OpenVZ and KVM
We offer our clients two types of server virtualization to choose from: OpenVZ (at the operating system level) and KVM (hardware).
Technology Openvz is based on the Linux kernel and allows you to create and run isolated copies of the operating system on one physical server - the so-called "virtual private servers" (Virtual Private Servers, VPS) or "virtual environments" (Virtual Environments, VE). This technology is characterized by high performance, ease of use and easy server management. The user can also increase the capacity of such a virtual server at any time. In this case, the choice of the operating system is possible only from a number of those proposed (Debian, CentOS, Ubuntu), since the virtual servers of a particular host machine use a common Linux kernel.
KVM(Kernel-based Virtual Machine) is a hardware virtualization technology that allows you to create a complete virtual analogue of a real physical server on a host machine. Each such server is allocated its own area in RAM and hard disk space, its own network card, which increases the overall reliability of such a server. In fact, KVM technology allows you to create a virtual server completely isolated from its "neighbors" with its own OS kernel, which the user can customize and modify to suit his own needs with virtually no restrictions. You can install any operating system: Linux, FreeBSD, Windows and even your own image. At the same time, changing the server resources is impossible - if your project "grows" from the initially selected tariff, you will need to order a more efficient virtual server for it at the corresponding tariff and transfer all data to it (as is the case with a real dedicated server). The exception is the VDS-Fast and the Furious and VDS-Atlant tariffs, where the user has the ability to change the number of available processor cores and RAM (hard disk - upon request to the support service).
Considering the features and advantages that KVM virtualization provides, its tariffs are somewhat more expensive than similar tariffs with OpenVZ virtualization. You can read more about comparing server virtualization technologies in our
3 votesGood day, dear readers of my blog. I recently wrote an article, I told you a little later, and today I finish this series of articles with a story about shared hosting. After you read all three publications, you will be able to accurately determine the tasks and the ideal way of placement for your site.
From this article you will learn everything about shared hosting, what it is and for what purposes it is better to use it. You will no longer be led astray by incomprehensible terms. You will have full knowledge of the information, you will be able to independently figure out the reasons for the appearance of several placement methods, the options for using each of them, and you will be able to choose the best one that fully suits your needs.
Before moving on to the main question, some may find my article useful, in which I talk about. If you already know this, then let's move on to the next level as soon as possible. If not, I recommend starting from the first step.
Terminology
Shared hosting on the Internet is a method of placement in which several sites are served on one server at once. This is the most profitable way, ideally matching the requests of small electronic resources.
When you rent a dedicated server or use VDS (VPS), you are given the opportunity to manage all the settings yourself. If a problem happens, you will most likely have to deal with it. Much depends on the partnership agreement. Sometimes the system administrator of the company from which you rent the server takes over some of the responsibility.
However, in any case, you should not meddle here without specific knowledge. You just do not understand what to do with it and will waste a lot of time. On the other hand, if you have received comprehensive information, then you will be able to rule the show yourself.
VPS and server rental are more suitable for popular projects with high traffic. It may seem to beginners that 100-200 people a day is already a lot. Nothing like this. Here we are talking about more serious numbers: 50 - 100 thousand.
As a rule, any site is created on virtual hosting, and over time it is transferred. It is not difficult, especially for those people who can manage the server themselves. They really need a rent.
A virtual server does not require any special knowledge or skills. As a rule, all activities are carried out using a simple control panel.
The amount of disk space and the number of sites that you can host is determined immediately, when choosing a tariff, and then adjusted. Some partners also offer additional bonuses like a free domain.
If there are any problems, misunderstandings and so on - you, as they say, should not worry. The team of the partner providing the seat will be obliged to handle everything.
Advantages and disadvantages
Basically, I think you already understood the basic information about the benefits. Let's recap briefly.
If you use shared hosting, then you have no opportunity to install software on it. Now we are not talking about any plugins or additional options for the site itself. I'm talking about a car, a server.
The webmaster is provided with a certain set of features that will ensure the normal stable operation of the site and the implementation of all ideas.
You will not be able to increase the amount of disk space or independently influence the loading speed of the portal for readers. All these characteristics are divided equally among all resources located on this server.
On the one hand, shared hosting has a significant drawback - a virus on one site can lead to problems for everyone else. On the other hand, this is not your problem. Access to the site, technical support, protection and server performance are the concern of the company that provides you with services.
The more popular the hosting, the more the developers care about its image. For several years now I have been using the services of the company TimeWeb and during this time I did not have any serious problems. So I recommend it.
Ideal for beginners
Recently I spoke with a guy who is engaged in professional video shooting. He was invited to work in America. No wonder, according to him, they have never seen a person independently engaged in the entire process from organizing light to installation. People there are not used to this. Each has its own narrow specialization.
It seems to me that this is partly correct. I do not understand people who want to comprehend all the nuances of work from the first day. Why would you also take on the responsibilities of a system administrator? Over time, if you need it, you will be able to understand what services he provides, whether it is worth hiring someone and how the work is done on the site. Until then, let others help you.
The financial issue will also play an important role in the decision. Shared hosting costs several times less, and many providers provide an opportunity to use it. You can get to know the basics of building sites on your own experience.
So that is all. Now you know what shared hosting is and even own a link to the ideal and almost free option for hosting. Until next time and good luck in your endeavors.
The service is called the placement of Internet sites, web services and other resources. At the moment, the cheapest popular type of hosting is considered to be shared hosting. There are even free options with no ads.
The difference between shared hosting and others
A distinctive feature of shared hosting is the ability to host a different number of websites on one web server. All sites are located in their own sections, but share the same software: linux or windows.
This option is most convenient for owners of small sites or those who do not want to spend their time and money on hiring system administrators and creating their own server.
As a rule, on shared hosting, a control panel with the necessary functionality is installed. The most common now are: DirectAdmin, cPanel, ISPmanager, Plesk, and others.
Who is the consumer of Virtual hosting services?
The market for offering virtual hosting services is so diverse that services can be provided by both novice schoolchildren and large companies. So all that remains is to make the right choice of a hosting provider, since the level of stability of your site's functioning directly depends on its quality of work. Choosing a quality hosting, you can be calm and confident in the continuity of your project.
The main methods for implementing access to resources are: using a public IP address, as well as an individual IP.
Shared hosting classification
Virtual hostings can be categorized by:
- The size of the provided disk space and RAM.
- The volume of monthly traffic.
- The number of sites placed under one contract.
- The availability of databases and the amount of space provided for them.
- The number of mailboxes.
When choosing a shared hosting, you should pay attention to the operating system used. Not only what software is used depends on this, but also the cost of services.
What operating systems are installed on the server
There are two groups: Linux (FreeBSD, GNU) and Windows. The major difference between the two is that Linux is mostly free and therefore the cost of UNIX and Linux hosting providers is slightly cheaper. This is because server owners do not pay a license fee.
Windows hosting differs in that both technologies developed exclusively for this operating system and those that were created for UNIX / Linux operate on it. Microsoft Windows allows you to work with ASP, NET, MS SQL, as well as PHP and MySQL. The use of these technologies has significantly increased the speed of the PHP "engine" in comparison with its work on the UNIX / Linux UNIX / Linux platform.
Hosting geographic location
The cost of shared hosting services is influenced by its geographic location. The main goal of domestic hosters is to make a profit of 100-200%, they also spend a lot of time and money on obtaining licenses and other permits. Therefore, a more profitable and convenient option would be to use the services provided by Russian-speaking or foreign companies from foreign countries.
Dedicated ip address
Shared hosting provides both a common IP address for all sites and a dedicated IP address service. This allows, in the event of DDOS attacks, to disable the very resource to which the attack is directed.
Unlimited disk space
Many providers in the contract describe the possibility of using unlimited disk space (a marketing move to attract more customers), although in fact the most greedy customers are "kicked out" using any pretexts:
- Limiting the number of files, after the automatic backup stops.
- Content that violates someone's rights.
Site security on shared hosting
It is a misconception that shared hosting is insecure. At the moment, there are many solutions to preserve the confidentiality of stored data.
Server loads
Shared hosting allocates a certain limit of processor time, memory, and sometimes hard drive for the account. If you exceed this limit, then you are warned or blocked for high load. The advantage is that you can change the tariff plan to a more resource-intensive one at any time.
Shared hosting is ...
Shared hosting- a type of hosting in which many websites are located on one web server. This is the most economical type of hosting, suitable for small projects. That said, each website is located on its own section of the web server, but they all use the same software together.
It should be noted that virtual hosting optimal for sites with traffic up to 1000 people per day. To host corporate sites with more traffic, it is more advisable to choose other types of hosting, for example, a virtual dedicated server (VPS). It allows you to serve a much larger number of visitors and provides uninterrupted access to the site from anywhere in the world.
Benefits of shared hosting
Shared hosting benefits:
- No special hosting skills required.
- Hosting management is carried out using a convenient control panel in Russian.
- Provided large amount of disk space.
- At the time of ordering hosting, it can be provided free of charge Domain name.
- Availability additional opportunities(exchange and transfer of data via FTP, access to site visit statistics, e-mail based on the site name, etc.).
- Cost minimization... Savings in the case of using shared hosting can amount to a significant amount, since you shift to the hosting provider the worries about round-the-clock support of expensive server equipment, software configuration, its regular updates, and ensuring a constant connection to the Internet.
Disadvantages of shared hosting
Disadvantages of shared hosting:
- You cannot install by yourself software.
- Physical resources(RAM, processor) are shared among several clients. You do not have exclusive ownership of all physical resources, as in the case of a virtual dedicated server (VPS).
What does the site offer?
The site specializes in providing services hosting in Belarus... Your site will be hosted on servers located in a data center in Minsk, which will increase the loading speed of your site. We only use own equipment, unlike most companies that are intermediary companies.
You also get the opportunity to fully work with hosting using master Plesk control panel, which has a simple and intuitive web-interface in Russian. With Plesk You yourself can:
- create domain and unlimited number of subdomains
- manage MySQL and MS SQL databases (create a database, users, etc.)
- create FTP accounts
- manage mail (create mailboxes, mailing lists, etc.)
- manage DNS server (create and edit DNS records to fine-tune hosting capabilities)
- control the use of server resources by your sites
- track the activity of users of your sites using the advanced statistics system AWStats
- use a large number of additional features
Shared hosting tariff plans
The site offers 5 main shared hosting tariff plans... Detailed characteristics are presented on the page shared hosting in Belarus.
Tariff plan "Start". 1500 MB of free disk space, the ability to host 1 site, an unlimited number of subdomains, support for all technologies. The number of mailboxes is not limited.
"Practical" tariff plan. 3000 MB of free disk space, the ability to host up to 2 sites, an unlimited number of subdomains, support for all technologies. The number of mailboxes is not limited.
Tariff plan "Business". 5000 MB of free disk space, the ability to host up to 4 sites, an unlimited number of subdomains, support for all technologies. The number of mailboxes is not limited.
Tariff plan "Master". 7000 MB of free disk space, the ability to host up to 6 sites, an unlimited number of subdomains, support for all technologies. The number of mailboxes is not limited.
Tariff plan "Profi". 10,000 MB of free disk space, the ability to host up to 10 sites, an unlimited number of subdomains, support for all technologies. The number of mailboxes is not limited.
Shared hosting features a higher level of security compared to traditional hosting, which does not provide full protection against resource attacks. And on a virtual server, the disk subsystem, network, processor and more are completely virtualized. And this approach allows shared hosting to provide complete isolation of servers from each other.
Providing unimaginable flexibility in server management, the virtual hosting service will undoubtedly appeal to "advanced" clients. Shared hosting is also a good choice for beginners who have at their disposal a fully configured, workable system with a convenient control panel.
Shared hosting Is the placement of a virtual web server on a server machine, whose resources it shares with other virtual servers. The advantage of this method is the low cost of the service and the fact that the owner of the virtual web server does not have to worry about his software either.
- databases: connection to DBMS databases (MySQL, PostgreSQL, Oracle, etc.), while access to the databases can be obtained from the outside.
PHP hosting: providing access to the PHP interpreter and PHP frameworks (for example, LIMB), additional libraries (such as IonCube Loader, Zend Optimizer, Suhosin Extensions), installation of various web applications: site management systems (CMS), organization systems forums, blogs, galleries, distance learning, news publishing and many others. PHP assumes you have access to the MySQL DBMS.
Python hosting: designed to host sites in the Python programming language. Providing access to the Python interpreter also implies the availability of a framework: Zope, Pylons, Django, TurboGears, etc. Plone hosting provides users with access to an already installed and configured Plone site publishing system. Python implies access to MySQL and PostgreSQL DBMS.
Perl hosting: Perl has significantly lost its position nowadays and sites are less and less common on it, however, usually Perl is supported on shared hosting.
RoR hosting or Ruby on Rails hosting: of course intended for projects written in Ruby and running on the Rails framework (MySQL required).
SVN hosting: focused primarily on professional developers. The SVN client in this case allows you to quickly update the changed files on the server without resorting to FTP access, and the SVN server allows a group of developers to work together, even if they are geographically separated.
In addition, virtual hosting provides access via FTP, SSH (chrooted SSH), SFTP.
Paid shared hosting should also provide:
Round-the-clock technical support for Clients; -backup (backup); -installation of web applications (CMS, blogs, forums, galleries, online stores, etc.).
Additional services include:
Domain registration;
-provision of SSL certificates.
