When it comes to choosing a web hosting service provider, the decision largely depends on the type of website being hosted. Nevertheless, there are certain crucial factors to consider regardless of the website type, especially in the case of VPS hosting.

It's worth explaining the differences between VPS hosting and cloud hosting, which is becoming more popular. In VPS hosting, users get a virtual environment with dedicated disk or SSD space and bandwidth, but host system computing resources and RAM are distributed equally among all VPS. Cloud hosting, on the other hand, involves virtual machines in the cloud. This type of hosting uses a distributed server infrastructure, allowing for more flexibility in the provisioning process and increased fault tolerance, but with more limited hosting options and configuration requiring a certain degree of knowledge.

So, what should you look for in a reliable and high-quality web hosting service provider? Here are some tips.

Firstly, choose a provider with an availability level guaranteeing good website performance. Using servers with insufficient processing power and unstable network connections can lead to low website ranking and hinder sales. A 99.5% guaranteed reliability level is standard, but sometimes a higher percentage rate may be required.

Secondly, pay attention to customer service quality. Does the provider offer 24/7 technical support via live chats and social media, or just through emails? Choose providers that have their own customer support department with certified specialists who can better understand the specific business needs.

Thirdly, data protection and regular backups are crucial in today's high-risk cyber environment. Hosts that provide regular backups can help prevent irreparable losses and facilitate data recovery in the event of a cyber attack.

Finally, don't forget to check registration, maintenance costs, and the ability to add domains. Some web hosting service providers may offer discounts for the initial period but charge much higher renewal fees.

In conclusion, choosing the right web hosting service provider can make a huge difference in the success of your website. So take the time to research and make informed decisions to ensure the best performance and user experience for your visitors.

When dealing with a medium or complex project that requires multiple virtual machines in one local network, settings for a load balancer, firewall, and other network services, a whole virtual data center (VDC) may be required. This is especially true if the capabilities of a typical VPS are not sufficient, and you want to create virtual machines with your own Operating System.

However, creating and managing a VDC requires a high level of knowledge of OS and network administration, along with experience in using products such as VMware or OpenStack, and familiarity with information security issues. VDCs are particularly useful for testing environments, or when there is a need to activate several VMs with dynamic billing based on resource consumption during peak periods.

Compared to VPS hosting, Virtual Data Centers offer more functions, including changing configurations and quantities, connecting different types of drives to the VM (HDD, SSD), installing your own OS, creating your own VM templates, and importing/exporting your own templates and VM ISO images. Additionally, users can create a network infrastructure with a firewall, NAT, DHCP, load balancer, and VPN (SSL, IPSec).

Using a Virtual Data Center allows customers to create and configure an unlimited number of VMs, set up network parameters, and create the required network topology, all with full control of cloud-based services. While VDCs offer both security and scalability, they tend to be more expensive than VPS hosting.

On the other hand, VPS hosting is recommended for individuals and small businesses with limited budgets. Similar to a dedicated server, it provides full control over the server at a much lower cost. It is recommended for personal use and SMB customers who do not require advanced customization and scalability features.

Typical examples of using a virtual server include website hosting and VPN servers. VPS hosting is the best solution for hosting websites since installation and configuration are simple and understandable even for beginners. It allows users to organize their workspace according to their specific requirements and manage multiple sites using a single control panel. Meanwhile, VPN servers are used to create an encrypted channel between a user's device and a remote virtual server to transfer sensitive information securely.


After trying out various VPS hosting providers, I arrived at a conclusion: if you purchase hosting from a company that isn't an expert in hosting, such as a domain registrar, there may be issues with the service. I encountered a server which was not wiped clean after the previous user (the system wasn't reinstalled), and glitches occurred while running certain php networking functions.

As someone who isn't a sysadmin, I spent days trying to resolve the problems by myself, but eventually I gave up and switched to a specialized hosting company that didn't have such issues.
