Proxy literally means “a representative”. It works as an intermediary between your device and the rest of the Internet. When your device sends a request, a proxy intercepts it and checks whether it has requested data in the cache. If yes, it returns the cached version of data without connecting to the requested resource. If not, a proxy server passes your request further but changes your IP to its own. Because of the fact that proxy hides an endpoint device’s IP addresses, it is often confused with a VPN. However, apart from the IP hiding, a VPN and a proxy server are used for different purposes.


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.
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.
Most VPS hosts only offer servers running Linux-based operating systems; you'll need to dig a bit to find Windows-based VPS hosting. This is important to note if you're planning on running software that requires a Microsoft-compatible environment. That said, Linux-based VPS hosting will save you a few bucks; Linux servers usually cost $10 to $20 less than Windows servers.
With VPS, you pay for what you use in the sense that you select a certain amount of bandwidth and storage to be allocated in advance. Scaling involves resizing your resources. But with cloud hosting, you pay for what you use in that your resource levels are not pre-determined, which means unpredictable pricing that tends to be more costly than VPS due to the overhead and complexity involved.
VPS stands for Virtual Private Server and refers to a private, emulated dedicated hosting environment created through virtualization on a host (a computer or other device connected to other computers or devices via a network), server (called the “parent server”), or cluster of servers. It acts like a physical server but, in reality, it’s a piece of software that’s emulating dedicated hardware.

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!
Two unique features that InMotion VPS hosting provides for free are the Resource Monitoring Dashboard which provides you with charts and graphs to monitor resource usage and allocation on your VPS partition and the Live-State Snapshots functionality, which goes beyond the (free) daily backups and allow you to restore your machine to a specific “known” working state.
As you can see, a VPS can be the perfect middle ground for many – enough flexibility and resources for those who need more access or control than on a shared server but without the cost of a dedicated server. If you need root access, you can’t get that on a shared server, but you can get it on a VPS. If your site experiences unpredictable swings memory usage, and your host provides it, then the presence of burstable memory will be attractive. And, if you’re a fan of customization, then the fact that you can customize server-level software such as PHP, MySQL, and Apache will perk your interest.  In short, choosing a VPS will allow you to have many of the same characteristics of a dedicated server but in a more affordable and manageable package.
