With dedicated hosting, you rent a dedicated server from the hosting provider’s data center. You can lease the entire physical machine and all of the accompanying resources. This means the server's CPU, RAM, storage, and bandwidth are all available to your organization. Most dedicated hosting providers guarantee a certain amount of uptime and offer support in case of server hardware failure or other technical issues.
Typically, you get root access or administrative access to the server. With this access, you can install software, manage user accounts, adjust server settings, and perform any administrative tasks. You can choose the operating system, software applications, and specific configurations that best suit your needs. You can also use your existing per-socket, per-virtual-machine (VM), or per-core software licenses. And you can virtualize and run multiple instances (or virtual machines) on your dedicated server.
In fully managed hosting services, your provider gives additional services like software updates, security patches, technical support, and server monitoring. In an unmanaged dedicated hosting service, you are responsible for all server-related tasks, including operating system updates, security patches, and backups.
