When many industry experts were predicting the imminent end of VPS, not only did it happen, but also these services took over many features previously reserved for the cloud like when you get Cheap Dedicated Server.
Customers have a lot to choose from, because suppliers offer three or four preconfigured variants of the service targeted at various groups of recipients and applications. The weakest configurations with 1 processor core and 1 GB RAM are the absolute minimum for web applications.
The most popular today are inexpensive configurations (1-2 processor cores, 2-4 GB RAM, 50-100 GB disk) that allow you to run a blog or a website with an average audience, a few small applications or an aspiring online store.
On the other, you will find powerful virtual machines with the power of multiple CPU cores and up to 32 GB of RAM ready to run. Each such server will allow you to handle even several large Internet projects simultaneously.
High availability and performance
There is a clear reversal on the market from classic VPS services run as part of a separate physical server in favor of virtual instances supported on a virtualization cluster or in a cloud infrastructure. An example of such an innovative approach is the VPS Cloudentic service operated in a high availability (HA) environment. All elements of the provider’s infrastructure have been duplicated, thanks to which the failure of a single resource or periodic maintenance works do not lead to the unavailability of the service for end customers.
Everyone can have their own virtual server
Currently, VPS prices are so competitive that virtually everyone can afford to buy their own virtual server. The prices of services start from just a few dollars a month, and depending on the user’s needs, the service can be adapted to a specific purpose and choosing the most appropriate package. Regardless of whether it will be setting up your own website, server for gaming purposes, or simply storing databases, the customer receives a guarantee that the server will be fully available. Providing adequate resources and access to them from anywhere systematically increases the group of supporters of VPS servers as a good alternative to both shared hosting and a much more expensive dedicated server.
Until recently, the bottleneck of VPS was access to data stored on traditional magnetic disks. Over time, they were replaced by local disks and disk arrays based on SSD and NVMe media, providing the required read and write performance for modern websites and Internet applications.
VPS servers are run on NVMe disks, up to 10 times faster than SSDs and up to 100 times more efficient than classic magnetic disks. It is an ideal solution for demanding databases and web applications.
Many vendors use OpenStack cloud arrays. Others – such use of dedicated SAN arrays with synchronous replication. The problem is that the disk space on fast semiconductor media costs a lot. As a result, a typical VPS configuration contains no more than 50-100 GB of disk space for user data. This is a lot if you run a blog and perhaps much too little if you want to set up mailboxes for dozens of company employees on one server.
It is worth mentioning that all processes of individual users who decide to use a virtual server take place independently. Thanks to this, many use the guaranteed resources allocated to the VPS server. The speed of the service is also crucial for the users. In the case of VPS, it is influenced by several factors. Access to high-performance networks as well as efficient and modern technical facilities are important. For example, currently very high speed of operation is guaranteed by solutions based on NVMe disk technology, which provide up to 10 times faster reading and writing of data compared to standard SSD disks and 100 times faster than in the case of HDD disks. It is an efficient solution that works well with databases and Java-based servers.
In the case of VPS servers based on full virtualization, the KVM environment dominates. It is not uncommon for KVM servers to run as part of a larger OpenStack cloud cluster. Some providers provide its virtual machines, prides itself on using the popular in business VMware virtualizer. Customers can choose between slightly cheaper VPS servers based on paravirtualization, and virtual machines with a full guarantee of resources, run on the basis of KVM.
The core of the offer of hosting providers are VPS servers in the root variant for self-management. Some providers went a step further, offering VPS services in the root and managed variant like VPS Malaysia.
The operator is responsible for server management, while the client can freely use a fully configured web environment with an intuitive, proprietary Web administrator panel, just like in shared hosting. All this at the cost of limited server flexibility.
At this point, it is impossible not to mention the Web Hosting service. It is a shared hosting service, but thanks to the resource guarantee (1 GHz processor, 1 GB RAM) with the possibility of scaling them up, for many customers it can be an interesting alternative to a VPS server in the managed option.
The client panel allows you to perform the most important administrative activities on the VPS server. It allows you to restart or stop the virtual machine, view event logs or change (rebuild) the installed operating system. All of this is done with just a few clicks of the mouse.
Convenient web server management, however, requires a deeper pocket. Providers offer the possibility of quick implementation of software such as Plesk, cPanel or DirectAdmin, but in principle, for most of them it is an additional paid option.
On a VPS server you can choose from major Linux distributions such as Debian, CentOS or Fedora. Similarly, Cloud has a huge number of preconfigured templates for operating systems and applications, including FreeBSD, pfSense and Microsoft SQL Server. Some providers also offer VPS servers with Windows Server. This is in case you need to support your web projects written in .NET architecture.
Finally, one more thing. In some providers, you will receive 1 IP address for the price of the server. Additional addresses if needed can be ordered for an additional fee. Which attaches as many as 4 public IP addresses to its VPS servers in the managed version. Such a pool of addresses, in conjunction with the containerization mechanism that allows you to serve many customers on one virtual server, already allows you to create a solid positioning back-end with IP addressing in different subnets.
Price is not the only advantage of VPS
The speed of service implementation is equally important. A person looking for a solution for himself often needs it almost immediately. In the case of services , the VPS server is ready for operation in just 15 seconds from the moment the payment is credited in some providers. This means that if you need a separate work environment, and you do not have an additional physical device, you can quickly purchase the appropriate resources from a proven supplier. This makes it possible to carry out tests in a safe environment, isolated from the company or production server. In this way, you create an efficient development environment, to which you have easy access at any time, the resources of which you can enlarge if the need arises.
