Virtualization 1
Enables a single computer to host multiple independent virtual computers that share the host hardware.
This happens when a dedicated server fails or goes offline. There are no backup servers to handle the failure.
What is single-point of failure?
This is the physical computer controlled by a user. VMs use the system resources of the host machine to boot and run an OS.
What is a host computer?
Separates the applications from the hardware.
What is cloud computing?
This Cloud is made up of two or more clouds where each part remains a distinctive object, but both are connected using a single architecture.
What is a Hybrid Cloud?
This happens when dedicated servers sit at idle for long periods waiting until they are needed to deliver their specific service.
What are wasted resources?
This occurs when an organization does not have enough space to physically house underutilized servers. The servers take up more space than is warranted by the services that they provide.
What is a server sprawl?
This is the operating system of the host computer
What is a host operating system (host OS)?
Examples of this are Office 365, Gmail, iCloud Mail, Outlook, Yahoo, and Exchange Online.
What is Cloud-based email?
Examples of this are Google Drive, OneDrive, Box, and Dropbox.
What is cloud file storage?
A special program used to manage the resources and various VMs.
What is a hypervisor?
This is the operating system that is running in the VM. Drivers are required to run the different OS version.
What is a guest operating system (guest OS)?
This is a computer that exists within a computer
What is a Virtual Machine (VM)?
Cloud-based applications and services offered are for a specific organization or entity, such as the government.
What is a private cloud?
The provider's computing resources are pooled to serve multiple consumers using a multi-tenant model.
What is resource pooling?
Also called bare-metal hypervisor and typically used with server virtualization. It runs directly on the hardware of a host and manages the allocation of system resources to virtual operating systems.
What is a type 1 (native) hypervisor?
This is hosted by an OS and is commonly used with client-side virtualization. Virtualization software such as VirtualBox and VMware Workstation are examples.
What is a type 2 (hosted) hypervisor?
Where information is stored somewhere else, and is remotely accessible over the network normally over the internet.
What is the cloud?
Cloud services are available over the network using many devices.
What is broad network access?
Includes tools and services used to deliver the applications, Includes OS and applications stack, and is typically requested by application and software developers.
What is Platform as a Service (PaaS)?
Requires 1 GHz 32-bit or 64-bit processor, 32 GB of memory, and 15Gb of Hard disk space (per Virtual OS)
What are the Windows 7 virtual PC requirements?
Needs Windows 8 Pro or enterprise 64-bit OS, 64-bit processor with second level address translation, BIOS-level hardware virtualization support, minimum 4GB of RAM, and at least 15GB of hard disk space per virtual OS.
What are the Hyper-V Windows 8 requirements?
Needs Windows 10 Pro or Windows server (2012 or 2016), 64-bit processor with SLAT, CPU support for VM monitor mode extension (VT-c on Intel CPU's), minimum 4GB of RAM, and at least 15GB of hard disk space per VM.
What are the Hyper-V requirements for Windows 10?
Software applications (e.g. email, Office 365, etc.) are provided over the network on a subscription basis and are typically used by end users
What is Software as a Service (SaaS)?
Includes network, computers (virtual or dedicated), and storage, and is typically used by organization infrastructure and network architects.
What is Infrastructure as a Service (IaaS)?
