Many owners of Internet resources host their web applications on virtual servers or use shared hosting. In this article, we will try to consider in detail both services, and based on the experience of the customer support service, we will deduce the conclusion: which of these services can be given preference and under what circumstances. Read all the details under the cut!
Suppose you have a website or plans to create one. You turned to a specialist who knows what technologies to develop a website. Most likely, he already has a personal idea of what hosting to host it and will offer a resource from his own developments. But you like to understand everything yourself, and therefore, in order to get to the truth, you need to puzzle about finding a reliable and really suitable web host. The same resource, which determines how your site will be placed on the Internet.VPS includes cloud Linux VPS, windows VPS hosting, etc.
VPS / VDS
These abbreviations are found quite often. Some write VPS, others use VDS. Both concepts appeared about the same time and in fact mean the same thing. VPS (Virtual Private Server) or VDS (Virtual Dedicated Server) is a virtual dedicated server.
It's the same computer as your home, and sometimes more powerful. For physical servers, processors from a special series are used, which are more expensive than for most home computers. Together with the memory of a special type, such processors guarantee the exact execution of programs. In addition, NVIDIA GRID and NVIDIA TESLA M60 graphics cards can be used in servers, which are needed for specific tasks and for the most part architects.
Virtualization is a technology that runs on a single physical computer several isolated virtual machines. In order to implement virtualization, technical means are needed. On each physical server (the provider can have hundreds of them), a hypervisor is installed. The servers are clustered and managed by the management server cluster. In VMware, it is called vCenter and allows you to efficiently distribute virtual machines to virtualization servers, manage hypervisors (servers, networks, storage, etc.).
Types of virtual servers
Historically, the first appeared on the market shared-server VPS. They are built, usually based on Linux upstream containers. Each client on such hosting gets an isolated container to host their files and applications. In this case, the user has access to limited rights within his VPS.
Today, this technology is becoming obsolete, and eventually, it will be completely replaced by cloud-based VPS, which has a number of advantages:
Virtual machines of users are independent - the influence of one user on others is excluded
Each VM can use its OS
The client receives full administrative access inside the VM and can install any software
VM can be moved between servers and exported/imported
When a physical server crashes, VMs are immediately launched on other servers
With a heavy load on the physical server, VMs are moved to less-loaded servers
This solution has been successfully applied in tens of thousands of companies, and over time, more and more organizations are discovering virtualization for themselves.
As a rule, this is a very simple type of hosting. A set of applications is installed on the provider's server - web server, DBMS, PHP, and so on. Each user can have a folder for placing files and a control panel from which he can configure the provided parts of the web server and DBMS for the needs of the site. The advantage of such hosting is low cost and simplicity.
Who should choose shared hosting?
Shared hosting is a solution that is suitable for sites with attendance of no more than 2000 people, or those who are difficult to configure the server. The advantage of this solution is the low price.
Who should choose a virtual server?
If you purchased a virtual server, you can count on a much larger number of visitors than in the case of shared hosting. In addition, it's not much more expensive if you really want to get high speed and smooth operation of the site. A dedicated Internet channel will allow visitors to work with your site at any desired time.
As in everything, you first need to decide what kind of requests you have for the project. If you plan to grow and increase your influence in the selected segment, then you need to stop at the virtual server. It is with it that your site will be able to receive more visitors simultaneously and avoid unforeseen breakdowns. Otherwise, shared hosting is suitable.
