* Overprovisioning: Involves allocating more virtual resources (e.g., CPU, RAM, storage) to virtual machines than the total physical resources available on a hypervisor. The idea is for resources to be dynamically shared, assuming not all VMs will demand their maximum allocation simultaneously.
* Direct Access: This usually refers to technologies like RDMA (Remote Direct Memory Access) that allow for very low-latency, direct access to the memory of another computer over a network.
* Link Aggregation: The practice of combining multiple physical network links to create a single logical link with increased bandwidth.
* Component Redundancy: Refers to having multiple hardware components (e.g., power supplies, hard drives) to provide fault tolerance.
* Scalability: The ability of a system to adapt and handle increased workloads by adding resources.
