There are numerous open source Linux virtualization platforms based on KVM, while Microsoft has Hyper-V with Windows cloud servers, Citrix maintains the Xen server framework, and VMware has a number of different hypervisor frameworks such as ESXi. Hypervisors permit the managing of multiple web servers independently on shared hardware each with isolated databases, file storage, and I/O request processing.
Unlike most shared web hosting plans with unlimited domains, almost all VPS hosting plans include metered bandwidth limits of between 1-5 TB per month. VPS hosting plans have better resource utility panels for administration than available with cPanel where web traffic statistics can be accessed in realtime and the levels of RAM, CPU cores, or bandwidth limits can be adjusted.
Liquid Web has been around for almost 2 decades and offers fast and reliable, fully managed VPS Hosting solutions. All of their VPS plans run on a proprietary Storm platform and available in Linux or Windows operating systems. Their Storm platform is both scalable and customizable to individual user needs. They provide 24x7 support on all plans. if you are looking for the of a power a Dedicated Server with features of a Cloud Server you should consider Liquid Web.
The force driving server virtualization is similar to that which led to the development of time-sharing and multiprogramming in the past. Although the resources are still shared, as under the time-sharing model, virtualization provides a higher level of security, dependent on the type of virtualization used, as the individual virtual servers are mostly isolated from each other and may run their own full-fledged operating system which can be independently rebooted as a virtual instance.
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.
Partitioning a single server to appear as multiple servers has been increasingly common on microcomputers since the launch of VMware ESX Server in 2001. The physical server typically runs a hypervisor which is tasked with creating, releasing, and managing the resources of "guest" operating systems, or virtual machines. These guest operating systems are allocated a share of resources of the physical server, typically in a manner in which the guest is not aware of any other physical resources save for those allocated to it by the hypervisor. As a VPS runs its own copy of its operating system, customers have superuser-level access to that operating system instance, and can install almost any software that runs on the OS; however, due to the number of virtualization clients typically running on a single machine, a VPS generally has limited processor time, RAM, and disk space.
A VPS runs its own copy of an operating system (OS), and customers may have superuser-level access to that operating system instance, so they can install almost any software that runs on that OS. For many purposes they are functionally equivalent to a dedicated physical server, and being software-defined, are able to be much more easily created and configured. They are priced much lower than an equivalent physical server. However, as they share the underlying physical hardware with other VPSes, performance may be lower, depending on the workload of any other executing virtual machines.
VPS, on the other hand, is an isolated playground specifically for you. You will be able to install and use any professional software you need. It also provides more opportunities for caching the content. Imagine that you implement caching tools to provide your users with better experience and reduce the loading time of your website. Caching means that the part of requests to your website will be processed using RAM instead of a hard drive. Eventually, RAM will be filled with these requests. Since VPS deals offer more RAM then shared packages, you will get better performance using caching.
Think of a shared server as a large apartment complex, and all of the individual apartments are rented by other website owners. All of you need a place to live — just like your website’s files — but going out to buy a huge family home would be too expensive for your needs. Sharing common areas and utilities in an apartment block helps keep costs down. And the same is true for shared hosting.
Many website owners are choosing VPS plans to implement advanced web page caching strategies with Nginx, Varnish Cache, & Redis that shared hosting plans do not normally provide. Advanced caching with Nginx and Varnish Cache can considerably speed up WordPress, Drupal, Joomla, & other CMS websites. VPS plans can also permit more advanced usage of APC, OPcache, &
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!
The great news for VPS customers these days is that most web hosting companies offer managed VPS hosting. Here, not only will they set up your server environment, but they’ll also take care of tasks such as software upgrades, security patches, etc. Also, provision time is now greatly reduced and you can be up and running with your VPS hosting much more quickly.
