chap 9 Flashcards
enables a single computer to host multiple independent virtual computers that share the host computer hardware.
Virtualization
separates the applications from the hardware. It provides organizations with on-demand delivery of computing services over the network. ex AWS

9.1.1.3 Traditional Server Deployment
3 types
wasted resources// This occurs when dedicated servers sit idle for long periods waiting until they are needed to deliver their specific service. Meanwhile, these servers waste energy.
Single-point of failure – occur when a dedicated server fails or goes offline. There are no backup servers to handle the failure.
server sprawl//when org , hen an organization does not have adequate space to physically house. when server takes MORE space,
The hypervisor, also called the Virtual Machine Manager (VMM), is the br
Type 1 (native) hypervisor – 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.
Type 2 (hosted) 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 of a Type 2 hyperviso
Virtual Machine Requirements
Processor support – Processors, such as Intel VT and AMD-V, were specifically designed to support virtualization. The virtualization feature on these processors may need to be enabled. Processors with multiple cores are also recommended as the additional cores increase speed and responsiveness when running multiple VMs.
Memory support – Consider that you need memory for your host OS and will now need enough RAM to meet the requirements of each VM and their guest OS.
Storage - Each VM creates very large files to store operating systems, applications, and all of the VM data. You must also factor in that an active VM will require a few GB of storage space. Therefore, large and fast drives are recommended.
Network Requirements
1/This is a computer that exists within a computer
2/ This is the physical computer controlled by a user.
3/This is the operating system of the host computer.
4/This is the operating system that is running on the VM.

he cloud provider provides access to operating systems, development tools, programming languages, and libraries used to develop, test, and deliver applications. This is useful to application developers. The cloud provider manages the underlying network, servers, and cloud infrastructure. ?? providers include Amazon Web Service, Oracle Cloud, Google Cloud Platform and Microsoft Azure.
Platform as a Service PAAS
The cloud provider manages the network and provides organizations access to network equipment, virtualized network services, storage, software, and supporting network infrastructure. . Organizations do not need to invest in capital equipment and only pay for usage on-demand. The provider network includes redundancy and eliminates a single point of failure in the provider network infrastructure. The network can also scale seamlessly based on current requirements. ??? providers include Amazon Web Service, DigitalOcean, and Microsoft Azure.

can be found on some laser and inkjet printers which also have the capabilities of copy machines. These are called multi-function devices (MFDs).
The scan is uploaded to a storage location in the cloud such as Google Drive or Apple iCloud. The MFD may have specific cloud locations that are preconfigured or allow you to configure your own. You log in using the scanning prompts either in the software or on the MFD screen if it has one. ?
The scan is sent to a network folder on the LAN. The scanning prompts should ask for the path to the folder to which you wish the scan to be saved.
?
The scan will be created as a file attachment in an email. The scanning prompts will ask for the hostname or IP address of the SMTP server and, often, the email account credentials. ?
