This technology allows multiple operating systems to run simultaneously on a single physical computer.
Virtual Machine
(VM)
Running a virtual machine is known as “virtualization”.
The practice of running potentially dangerous or unstable programs in a virtualized environment.
Sandboxing
Sandboxing separates virtual machines from the host system.
This is any outdated or obsolete computer system, application, or technology that is still in use.
Legacy
This technology runs user desktops on a cloud server. Also called “Desktop as a Service”.
Virtual Desktop Infrastructure
(VDI)
True or False:
Virtual machine processing and network connections are managed through a hypervisor.
True
Hypervisors manage almost all aspects of the virtual machine environment.
This modular application instance contains the operating system, code, dependencies, and everything else needed to run an application.
Virtual machine
This modular image contains the code and dependencies needed to run an application.
Application container
What hypervisor type runs on bare metal?
Type 1 Hypervisor
On a “bare metal” system, the hypervisor is the primary operating system.
This hypervisor type runs on top of an existing operating system.
Type 2 Hypervisor
Type 2 hypervisors run on top of Windows, Linux, macOS, or any other operating system.
This is the general name for scalable servers acting as remote applications and services with flexible service costs.
Cloud computing
These are cloud services running from an organization’s own virtualized local data center.
Private cloud
This describes cloud services available to anyone on the Internet.
Public cloud
This is a mix of both private and public cloud services.
Hybrid cloud
A shared cloud infrastructure used by several organizations.
Community Cloud
This cloud model includes CPU, network, and other hardware, but the operating system and applications are usually the customer’s responsibility.
Infrastructure as a Service
(IaaS)
A cloud model where all software, hardware, and ongoing maintenance is managed by the cloud service provider.
Software as a Service
(SaaS)
Notable examples include Google Mail and Microsoft 365.
A cloud model which provides a framework for building applications.
Platform as a Service
(PaaS)
Name the cloud characteristic:
The purchase of equipment and software for an organization to build their own cloud.
Internal or private cloud
Name the cloud characteristic:
Services are available with a third-party cloud provider, and these services are available to anyone on the Internet.
External or public cloud
Name the cloud characteristic:
The customer is billed based on the use of storage, egress, ingress, and other fees for cloud services.
Metered services
Name the cloud characteristic:
The costs associated with cloud services are at a fixed rate.
Non-metered
Name the cloud characteristic:
Application instances will automatically scale up and down as demand changes.
Rapid elasticity
Name the cloud characteristic:
Redundant systems are in place to protect against any unplanned outages.
High availability
Name the cloud characteristic:
Customer data is duplicated across multiple locations.
File synchronization
