To host a website on the internet, a server is required. Hosting is the ability to place your resource on a provider’s server for a fee. There are several possible solutions that are popular. Traditional providers are becoming less popular because they do not provide the required functionality and performance.
Hosting on virtual or dedicated servers has become more popular. Cloud technologies are also used, which significantly reduce computing power. The choice of one or another solution depends on the direction of activity, goals, and traffic. To choose hosting, it is important to consider many factors.
Definition of VPS and VDS
VPS is a technology used to host websites on dedicated virtual servers. It is one of the most common ways to host websites on the internet, providing high performance and 24/7 accessibility.
Essentially, it is a distributed system with a certain number of virtual machines running on it. In terms of functionality and usage principles, it is virtually indistinguishable from physical devices, making it more user-friendly. By ordering a virtual server, the user obtains root rights and can perform all necessary actions during the operation.
VDS is a technology that involves using dedicated virtual space. These concepts are different, so dedicated and private server technologies should not be confused.
The essence of the work is as follows: the device is capable of running several virtual machines simultaneously, and their number depends on the computing power of the installation. As a result, various separately functioning machines are created, operating independently of each other and exchanging all information during operation and data processing on the server side.
This solution allows creating different IP addresses for each virtual machine regardless of its load. Also, you can manually specify the address or use the same address for multiple devices.
The characteristic of virtual space operation is that there are no restrictions on the amount of information that can be hosted. The user can host websites, addresses, and other data in any quantity. The breakdown of one virtual server will not affect the entire system, making repairs easier and allowing the website to remain operational. Creating backup copies of information and the website allows quickly moving everything necessary to another virtual server while preserving all the information.
The work of a virtual server is made possible by technologies that use virtualization as a working tool. Virtualization facilitates logical separation of different computing processes, allowing each server to work independently of others. There are different types of virtualization:
Operating system platform. Separate copies of the operating system kernel are launched and work independently of each other. Linux is used as the operating system. The user has the right to install only Linux. This method is distinguished by its simplicity of management, even for inexperienced users. Different providers use this technology and technical support is provided.
Using hardware components. Specialized equipment is used for this purpose. A hypervisor is a hardware device that allows multiple virtual machines running on different software and hardware platforms to be launched on one hosting. This is a more complex option to maintain. It enables the servicing of large projects, provides access for users with different levels of access, and has high throughput and flexibility.
The choice of a dedicated server technology depends on the scale of the project and the capabilities of the owner. When choosing, it is important to consider the possibility of scaling and the level of system load.
What are the main differences between VPS and VDS?
Dedicated and private servers are practically indistinguishable. They provide the same functionality and use similar technologies. If translated literally, VPS and VDS represent computing power for independent use. These concepts are identical, so they are used interchangeably.
Virtual Dedicated Server (VDS) is a technology that allows for the deployment of a distributed virtual system, providing access to remote resources as needed and managing large computing power. This is an optimal solution for developers and testers of applications. The main features and characteristics of VDS are:
- Independent virtual machines. The virtual machines are located in separate spaces on a physical server and have their own address environment, allowing them to work independently without auxiliary systems.
- Necessary resources. The performance of each individual machine does not affect the others. Each machine uses its own resources, and data exchange between them is possible through the main server via a specific protocol, ensuring the operation of the distributed virtual system on the server side.
- Ability to change IP address. Each virtual device uses a separate address space, ensuring distribution of information and protection against outsiders.
- No limitations. The number of hosted sites and visits is unlimited. This technology has high throughput and provides the necessary system performance.
Dedicated servers are advisable for large projects. Using them for launching simple websites and other basic web pages would be a waste of resources.
Physical servers are becoming less and less used due to the high costs of maintaining their operability. The optimal solution is to use a dedicated server. Among its advantages are:
Affordable cost. The rental price is much lower than when using physical computing resources. At the same time, there is no need to worry about installing licensed software. The provider takes care of this task.
Scalability. Dedicated computing power is easier to upgrade. It does not require restarting the computer. It is enough to update the program.
Ease of use. Creating a copy and archiving information takes less time. Anyone can manage the system after studying the instructions.
A dedicated server is characterized by a high degree of protection. All security protocols are updated automatically. Using the server side in the form of a physical device makes sense only if significant computing power is not required.
A virtual dedicated server (VDS) is required to perform various tasks. This technology is used for large websites and online stores. VDS is used in the following cases:
- For the functionality of medium and large websites. User information is protected by security protocols. The site is hosted on a flexible and reliable platform.
- For those who plan to increase the number of site visits in a short period of time. Processing large traffic requires computational power.
- For hosting multiple websites that need to be scaled. This provides an increase in traffic.
Dedicated hosting guarantees the security and protection of user information. As a result, the owner gains control of the control panel and uses only the necessary programs for work.
What to choose: cloud or dedicated server?
There is no universal solution for hosting websites. Cloud and virtual servers have different functionality, so they are used for different purposes. When choosing a cloud or dedicated service, the functionality and required work parameters are taken into account.
Dedicated server resources are chosen for small or temporary projects. This is suitable for small organizations operating on a local scale.
Large-scale projects require other tools that provide dedicated cloud technologies. They allow scaling and changing computing power depending on the degree of project development.
Choosing one or the other option is not an easy task. It is recommended to consult with specialists who can help with the installation of programs, explain the features of support and management. Only a good provider will provide everything necessary for optimal website performance.
