Ans: OpenStack is a free and open-source software platform for cloud computing, mostly deployed as infrastructure-as-a-service, whereby virtual servers and other resources are made available to customers.
Ans: OpenStack Nova is a component within the OpenStack open source cloud computing platform developed to provide on-demand access to compute resources by provisioning and managing large networks of virtual machines (VMs).
Ans: OpenStack Neutron is an SDN networking project focused on delivering networking-as-a-service (NaaS) in virtual compute environments. Neutron has replaced the original networking application program interface (API), called Quantum, in OpenStack.
Ans: OpenStack is an open source software that allows for the deployment and management of a cloud infrastructure as a service (IaaS) platform. OpenStacksupports both private and public cloud deployments. It fulfills two main requirements of the cloud: massive scalability and simplicity of implementation.
Ans: OpenStack Networking, otherwise referred to as Neutron, is one of many core projects within OpenStack. If we go back a little further, networking was actually part of the Nova project and was called Nova-networking.
Ans: Red Hat Enterprise Linux OpenStack Platform uses the Red Hat Enterprise Virtualization (RHEV) hypervisor, which is based on the open source KVM hypervisor. The distribution became available in June 2013 and runs on any hardware certified for Red Hat Enterprise Linux (RHEL).
Ans: OpenShift Container Platform (formerly known as OpenShift Enterprise) is Red Hat's on-premises private platform as a service product, built around a core of application containers powered by Docker, with orchestration and management provided by Kubernetes, on a foundation of Red Hat Enterprise Linux.
Ans: ESXi is a hypervisor but not a Cloud platform or toolkit. The VMware products that most directly map to OpenStack is not vSphere or ESXi, but vCloud Automation Center and vCloud Director. In fact, OpenStack does not have it's own hypervisorbut manages different hypervisors, such as KVM, Xen, Hyper-V, AND ESXi.
Ans: OpenStack works with popular enterprise and open source technologies making it ideal for heterogeneous infrastructure.” From AWS “Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides resizable compute capacity in the cloud. It is designed to make web-scale cloud computing easier for developers.
Ans: Enterprise Private Cloud. Our enterprise-class, hosted managed private cloud is a globally available service and is also built on the Openstack platform. It acts as a single pane of glass for provisioning, monitoring and management of resources via a self-service portal.
Ans: Newton Dashboard Screenshots. OpenStack is a Cloud Operating System that provides one versatile platform for all your compute, networking and storage resources. With the Ironic bare metal service, you can easily manage your servers as a driver to Nova Compute or as a standalone service.
Ans: OpenStack Compute (Nova) runs on a variety of hypervisors, including those from VMware, Citrix, and Microsoft, to name a few. ... KVM turns the Linux kernel into a hypervisor, and comes standard with many Linux distributions.
Ans: virsh is a command line interface tool for managing guests and the hypervisor. Thevirsh tool is built on the libvirt management API and operates as an alternative to the xm tool and the graphical guest Manager( virt-manager ).
Ans: The virsh program is the main interface for managing virsh guest domains. The program can be used to create, pause, and shutdown domains. It can also be used to list current domains. Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes).
Ans: Kernel-based Virtual Machine (KVM) is a virtualization infrastructure for the Linux kernel that turns it into a hypervisor. It was merged into the Linux kernel mainline in kernel version 2.6.20, which was released on February 5, 2007. KVM requires a processor with hardware virtualization extensions.
Ans: A hypervisor or virtual machine monitor (VMM) is computer software, firmware or hardware that creates and runs virtual machines. A computer on which a hypervisorruns one or more virtual machines is called a host machine, and each virtual machine is called a guest machine.
Ans: Examples of this type of hypervisor include VMware Fusion, Oracle Virtual Box, Oracle VM for x86, Solaris Zones, Parallels and VMware Workstation. In contrast, a Type 1 hypervisor (also called a bare metal hypervisor) is installed directly on physical host server hardware just like an operating system.
Ans: In computing, virtualization means to create a virtual version of a device or resource, such as a server, storage device, network or even an operating system where the framework divides the resource into one or more execution environments.
Ans: "Cloud computing is the delivery of shared computing resources, software or data — as a service and on-demand through the Internet." Most of the confusion occurs because virtualization and cloud computing work together to provide different types of services, as is the case with private clouds
Ans: A Type 1 hypervisor (sometimes called a 'Bare Metal' hypervisor) runs directly on top of the physical hardware. Each guest operating system runs atop thehypervisor. ... Each guest operating system then runs atop the hypervisor. Desktop virtualization systems often work in this manner.
