OpenNebula has a dedicated Quality Assurance (QA) team that deals with both unit and functional tests with a wide range of scenarios. Maybe, in some environments, VMware hypervisors are required due to strict software certification licenses, which are not so easy to circumvent in Enterprise software. VMware Server: It is a free (not open source) hypervisor, available for installation on Linux and Windows; it includes a Java web interface such as ESX, but with fewer features. VirtIO devices are supported natively by recent Linux releases, and their downloadable drivers are available even for Windows. After the Xen dominance in the past, the Kernel-based Virtual Machine (KVM) has grabbed more attention from the public in recent years (http://www.linux-kvm.org/). Federation: It is the ability to combine together different clusters, dislocated in different physical positions, enabling higher levels of scalability and reliability. paravirtualization, meaning that virtual machines required a modified operating system if they were to run well with negligible virtualization overhead. Now you have an overview of what the OpenNebula project is and how it fits into the cloud computing environment. Enterprise cloud computing is the next step in the evolution of data center virtualization. As in Xen, KVM supports paravirtualization thanks to the implementation of VirtIO devices. It runs on the the same logic that applies to a power grid providing energy to different houses, where a consumer does not need to know how the power is produced or how it is delivered to the house. 2.5 Min Read More. For performance reasons, the core of OpenNebula is written in highly optimized C++ code, giving good scalability. On the lowest level, there are drivers that directly talk to the underlying software OS components. Who. For a Public cloud, the main feature is exposing the cloud resources to externals with one or more standard interfaces, such as the cloud interfaces that enable the reachability of cloud resources, in a secure way, to external users, with OCCI and EC2 standard API interfaces.

We will mainly take into consideration VMware ESXi because of its Xen-/KVM-like architecture than the other two VMware products considered independently. OpenNebula is an open source management tool that helps virtualized data centers oversee private clouds , public clouds and hybrid clouds . Each virtual network is isolated with a firewall, ebtables (http://ebtables.sourceforge.net/). However, keep in mind that the infrastructure used by OpenNebula is common. It works at the Address Resolution Protocol (ARP) level, also known as the data link layer in the OSI stack. Finally, OpenNebula includes support for a range of VMware hypervisor versions (http://www.vmware.com/products/datacenter-virtualization/), that including the following: VMware ESXi: It is a free (not open source) hypervisor, the simplest of the whole family, and natively includes only a command-line interface, and runs on its own kernel (not on Linux, as Xen/KVM do). VMware hypervisors historically offer better performance and are better integrated with Windows virtual machines. Virtual Machine drivers: These are hypervisor-specific and they are used for managing the virtual machine instances on the current hosts. For similar reasons, another open source project has been ported to support the KVM interface in gaining a full virtualization environment, QEMU. It is used to manage all the other deprivileged instances. $35.99; $35.99; Publisher Description.
