RAID storage differentials are largely based on the number of disk drives and synchronized duplicate copies of data files available. SSD storage with Docker containers, Kubernetes elastic cloud networks, and isolated VPS/VM partitions are considered fundamentals in cloud data center architecture today. Many shared Linux webhosts make extensive use of SSD storage in VRAM configurations.
So that’s it, then – a VPS is for everything in between, right? Well, yes…and no. A VPS (Virtual Private Server) is a flexible solution that falls in between shared and dedicated hosting, not only in price but also in the way it functions. Like a dedicated server, a site hosted on a VPS gets its own RAM and disk space; however, like a shared server, it uses the same processing capacity (CPU) as a certain number of other sites. So, while your site’s performance isn’t reliant on shared RAM and disk space, it is dependent on a shared processor. Moreover, the distribution of processor share varies from provider to provider. The table below shows how most hosting companies break down the differences between shared, VPS, and dedicated hosting plans:
