What are the reasons for needing a separate server? Full control over the operating system, the ability to install any software, and a guaranteed level of performance. However, shared hosting is a cheaper option for small sites, but limits software options and web site performance may depend on neighboring sites' load.

With a separate server, you have full control over system security and reliability but require system administration skills. Virtual servers offer more recovery tools than hardware servers and allow for quick changes in computing power. Hosting in the cloud also allows for quick creation and deletion of virtual servers, making it extremely flexible.

It is natural that a dedicated server requires a serious administration and configuration skill. In other words, the main difference for me personally of this type of hosting is the need to hire a system administrator - a separate person to manage the entire "household". The weak link here is hardware and scalability. Therefore, in this case, a hosting provider must be selected that guarantees (and has proven in practice) that it can quickly "lift" the system in case of a breakdown.

For a fast and technically problem-free website, it's important to have all necessary hardware resources available. A dedicated server is the most logical solution as it ensures consistent performance without interference from neighbors or competitors. It also offers enhanced security with no other unauthorized users on the server.

 To prepare for sudden spikes in traffic during promotions or sales, it's recommended to use a server with extra power or consider distributing functions among multiple servers for fault tolerance. When the website continues to grow, buying and colocating your own servers may be an option, but it requires procurement, logistics, and administration specialists. Renting servers offers a fixed monthly payment and resolves all hardware issues through the provider.

Hi,
As long as your site is undemanding, extremely simple and does not have any additional services or does not require computing power, shared hosting will be enough for you.
But as soon as the site grows up or was originally created as a gaming store, the situation changes significantly. Here, first of all, we are talking about generating a large amount of traffic, but also - due to the information content of the portal - about the large amount of required disk space. Dedicated servers will also be needed if used in large companies that require an independent environment with high computing power.
