What are the advantages of a VPS, compared to a dedicated server?

The advantage of a VPS is that you don’t have to worry about hardware management — so you would not need to monitor the status of hard disks, RAM, and CPU. They are adapted to host most types of web projects that are moderately sized.
We recommend using a dedicated server if you want to manage the hardware aspects yourself, build more elaborate architectures, create an infrastructure that includes a private network (vRack), and deploy other complex solutions that are not web services.
As a general rule, users with a growing volume of web activity either move up to dedicated servers, or Public Cloud solutions. These services offer more complex, flexible infrastructures that can adapt to a high level of growth.
