CompTIA CloudNetX CNX-001 Flashcards
| Front | Back |
| Bare-Metal Hypervisor | Another name for a Type 1 Hypervisor |
| Cloud Infrastructure | The framework of physical and virtual resources enabling cloud computing |
| Cloud Load Balancer | A tool to distribute incoming traffic across multiple virtual machines or servers |
| Cloud Orchestration | Automating the management, coordination, and deployment of cloud services |
| Cloud-Native Applications | Applications designed specifically to run in a cloud environment |
| Container | An abstraction that packages an application and its dependencies to run consistently across environments |
| Disaster Recovery in Cloud | A strategy that uses cloud-based resources to ensure data and services remain available after a failure |
| Elasticity | The ability to dynamically allocate and scale resources up or down based on demand |
| Guest Machine | A virtual machine running on a host machine |
| Host Machine | The physical computer on which virtual machines are running |
| Hyper-Converged Infrastructure (HCI) | An IT framework combining compute, storage, and networking in a single system |
| Hypervisor | Software that creates and runs virtual machines by abstracting underlying hardware |
| IaaS (Infrastructure as a Service) | A cloud computing model providing virtualized compute, storage, and networking resources |
| Live Migration | VM migration performed while the virtual machine remains operational |
| PaaS (Platform as a Service) | A cloud computing model that provides a platform to develop, run, and manage applications |
| Resource Pooling | The practice of combining physical resources to serve multiple virtual environments |
| SaaS (Software as a Service) | A cloud computing model delivering software applications over the internet |
| Scalability | The capacity to handle an increasing workload by adding resources |
| Storage Virtualization | The pooling of physical storage from multiple devices into a single, manageable resource |
| Thick Provisioning | A storage method that preallocates storage in advance for a virtual machine |
| Thin Provisioning | A storage allocation method that allows virtual resources to exceed the actual physical capacity |
| Type 1 Hypervisor | Hypervisor that runs directly on physical hardware without an operating system |
| Type 2 Hypervisor | Hypervisor that runs on an operating system installed on the host machine |
| vCPU (Virtual CPU) | A logical CPU provided to a virtual machine by the underlying host machine |
| Virtual Machine (VM) | A software-based emulation of a physical computer |
| Virtual Network | A logically defined network that operates on physical network infrastructure |
| Virtualization | The process of creating virtual versions of physical hardware such as servers, storage, and networks |
| Virtualization Benefits | Increased resource utilization, reduced hardware costs, and improved scalability |
| VM Migration | The process of moving a virtual machine from one host to another |
| VM Snapshot | A saved state of a virtual machine that can be restored to later |
This deck focuses on virtualization concepts, hypervisors, resource allocation, and cloud infrastructure components.
