Similarly, in the case of VPS, there are several users that are using the same server but they are isolated from each other. It means that no one will be affected by how much resources another is using. You will get the speed and security that you need without compromise. It is almost a perfect scenario because you will get the benefits of a private server with shared cost of services.
CentOS Enterprise Linux is one of the most popular web server operating systems found on web hosting plans, and most companies provide licensed use of the software for free with hardware. Major web hosting companies can take advantage of bulk licensing fees for cPanel & WHM with CentOS servers, which are considered to be some of the most stable and secure Apache web server frameworks available. cPanel is primarily bundled with CentOS and WHM or WHMCS, although it is also available installed on CloudLinux or RHEL. CentOS is the most common Linux OS found on shared hosting plans.
There are a few downsides to shared hosting, though, mostly because you’re sharing. For instance, if someone else on your shared server has a huge spike in traffic, that could affect your website’s performance. However, if you’re just getting your website off the ground and don’t have huge traffic volume, shared hosting is a great way to get online!
It can take hours to build a web server with support for all of the programming languages and latest web standards. Managed VPS plans bring all of the software required for programming and web development (DevOps) into a PaaS product that is available instantly. From this, there are also many differences in LAMP stack configurations between webhosts. Buying a Managed WordPress VPS hosting plan with pre-configured Nginx and Varnish Cache installation can save thousands of dollars in web development costs for small businesses.
The hypervisor provides each guest machine (each website using the VPS) with a virtual operating system and takes care of managing and executing guest operating systems. This process makes the most effective use of computer resources such as network bandwidth, memory space and processor cycles. For this reason, a hypervisor also goes by the name of a virtual machine monitor (VMM).
The current trend in Linux web server OS distributions is for extremely lightweight installation requirements and integration with containers for elastic scaling of big data applications. Rancher and CoreOS both work with Docker and Kubernetes as well as other cloud orchestration platforms like OpenStack, CloudStack, CloudFoundry, OpenShift, Mesosphere, etc. Lightweight OS installations increase the number of virtual machines that can be created on data center hardware, leading to greater efficiency in production environments.
