A VPS, short for virtual private server, is a virtual machine you can use as an environment dedicated to your web projects. It is scaled to offer the resources you need, making it much more affordable than a dedicated server, but offering you full control over its administration and configuration. How much RAM does your VPS need for website & server management? If you are planning to manage your single website or server via the VPS hosting plan, then 1GB to 2GB of RAM should be sufficient for your needs.
