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.
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!
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.
