Cloud and Virtualization Flashcards
What are some benefits of implementing cloud and virtualization?
It requires less energy, less equipment, less space, and can help with data recovery.
What is a public cloud?
A cloud that provides services to the general public.
What is a private cloud?
A cloud that provides services to specific entities or companies such as the government.
What is a hybrid cloud?
A hybrid cloud is a cloud that consists of two or more clouds. The degrees of access vary per user
What is a community cloud?
A community cloud is specifically customized for a certain community, such as the Heathcare community. The customization is what differentiates it from a public cloud.
What are some different cloud services?
- SaaS (Software as a Service)
- PaaS (Platform as a Service)
- IaaS (Infrastructure as a Service)
What is SaaS?
Software as a Service. Software as a Service is access to software on a subscription basis. An example is Netflix.
What is PaaS?
Platform as a Service. Platform as a Service provides a platform for developing, running, and managing applications without the complexity of building and maintaining the underlying infrastructure. An example is Heroku.
What is IaaS?
Infrastructure as a Service. Infrastructure as a Service is a cloud computing model where essential computing resources, such as virtual machines, storage, and networks, are provided as a service over the internet. An example is IBM Cloud’s Virtual Servers.
What is virtualization?
Virtualization is the ability to abstract or separate the operating system from the physical hardware
What is a hypervisor?
A hypervisor is a program, firmware, or hardware that adds an abstraction layer on top of the physical hardware.
What are the two hypervisors used in virtualization?
Type 1 Hypervisor a.k.a. Bare Metal
Type 2 Hypervisor a.k.a. Hosted
What is a type 1 “Bare Metal” hypervisor?
A type 1 “Bare Metal” hypervisor is a virtualization software that runs directly on the physical hardware (bare metal) of a server without the need for an underlying operating system
What is a type 2 “Hosted” hypervisor?
A type 2 “Hosted” hypervisor is a virtualization software that runs on top of the existing operating system
What uses all the RAM, processing power, and hard drive space devoted to one service?
A dedicated server
