If you use shared hosting and your site is getting slower lately especially when you have many visitors, then it’s time for you to upgrade your shared account on VPS hosting or rent a dedicated server. Note: before you upgrade your account, you need to understand what VPS and dedicated hosting is. So you will not make a mistake while upgrading to the service to next level.
Here is a review for each service.
VPS, as the name suggest a server that runs on a virtual environment. While a host server is partitioned and each partition performs a VPS server, this type of accommodation is more powerful than shared hosting because you have more resources that are dedicated to you. VPS acts like a complete server so that you can install OS of your choice and able to install any application that you want.
