VPS is an acronym that stands for a virtual private server. When renting a VPS, the client gets a part of a physical server, which has almost the same functions and features as a separate full-fledged server. However, there are some limitations: for example, VPS does not provide access to the operating system kernel, and the choice of available control panels is limited by the hosting provider. Otherwise, VPS servers offer the same benefits as a physical server:
High stability, safety, and fail-safety of VPS based on Kernel-based Virtual Machine software solution are also of great value. KVM virtualization provides support of all actual protocols and firewalls, guarantees a high level of privacy and independence of server neighbors' resources from each other. Simply put, if your hardware capacity is idle for any reason, other clients will not be able to use it under any circumstances - this achieves benchmark performance and minimizes server response time.
Shared-hosting - a more affordable variant of server hosting, where several sites of different clients are located on one web server. Shared hosting has several advantages:
But there is a huge disadvantage of shared hosting - the neighboring sites on the same server can affect your safety and available hardware capacity. Because of this, shared-hosting is famous for its instability and low fault tolerance compared to VPS. In addition, when using shared hosting, there are a lot of restrictions. For example, you will not be able to change the software, and even the control panel will not be able to change - will have to use that offers the hosting provider. There are plenty of other restrictions, which are due to the need to ensure the stable operation of multiple sites on one server, and it differs from hoster to hoster.
Thus, if you need a reliable and stable solution to maintain projects of any complexity, it is better to prefer a physical server or VPS. Virtual hosting - a cheap alternative with some limitations, which is suitable for the placement of landing pages or other sites with low attendance.
