The only limits are the physical parameters of the server (disk space, memory, processor power, and network bandwidth). You can host websites, services, and databases; use it for trading, intensive calculations, gaming servers, proxy solutions, VOIP gateways, etc. With full root/administrator access to your VPS, you have the freedom to install virtually any compatible software or application that meets your requirements, including web servers, databases, development tools, and more. However, activities like spamming, phishing, or any crime under US law are prohibited. For clarity on prohibited activities and content, please refer to our terms of service, our Restrictions on Applications section within our Universal Terms of Service Agreement and Hosting Service Agreement.
