Virtualisation

Hardware level

QEMU

Xen

  • Xen Hypervisor is an open source virtualization platform that powers the world's largest clouds in production and is the foundation of many commercial products. Xen powers public clouds such as Amazon Web Services, Rackspace Public Cloud and many others. Examples of Xen based server products include Huawei UVP, Oracle VM and XenServer. Examples of client products and appliances include QubesOS, XenClient and Netscaler. Xen is 9 years old, mature and its stability and versatility is second to none.

KVM

  • KVM (for Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware containing virtualization extensions (Intel VT or AMD-V). It consists of a loadable kernel module, kvm.ko, that provides the core virtualization infrastructure and a processor specific module, kvm-intel.ko or kvm-amd.ko. KVM also requires a modified QEMU although work is underway to get the required changes upstream. Using KVM, one can run multiple virtual machines running unmodified Linux or Windows images. Each virtual machine has private virtualized hardware: a network card, disk, graphics adapter, etc.

VirtualBox

VirtualBox config;

  • Enable host Linux modules: vboxnetflt and vboxnetadp
  • Enable host-only adapter 'virtualbox0' in VB Preferences > Network if not previously enabled, then select in guest preferences
  • Keep VM names lowercase and no spaces for easier command-line stuff

Install guest additions for mouse, etc.

Provisioning VirtualBoxes for local dev work;

Vargrant
  • Vagrant uses Oracle’s VirtualBox to build configurable, lightweight, and portable virtual machines dynamically. The first couple pages serve to introduce you to Vagrant and what it has to offer while the rest of the guide is a technical walkthrough for building a fully functional web development environment. The getting started guide concludes by explaining how to package the newly created vagrant environment so other developers can get up and running in just a couple commands.
vagrant package --vagrantfile Vagrantfile.pkg --include README.txt
  stored in ~/.vagrant.d/boxes
vagrant box add lucid32 http://files.vagrantup.com/lucid32.box
vagrant box remove lucid32
vagrant box list
  • Veewee is a tool for easily (and repeatedly) building custom Vagrant base boxes, KVMs, and virtual machine images.

Operating system level

  • Operating system-level virtualization is a server virtualization method where the kernel of an operating system allows for multiple isolated user-space instances, instead of just one. Such instances (often called containers, VEs, VPSs or jails) may look and feel like a real server, from the point of view of its owner. On Unix systems, this technology can be thought of as an advanced implementation of the standard chroot mechanism. In addition to isolation mechanisms, the kernel often provides resource management features to limit the impact of one container's activities on the other containers.

LinuX Containers

Linux-VServer

  • Linux-VServer provides virtualization for GNU/Linux systems. This is accomplished by kernel level isolation. It allows to run multiple virtual units at once. Those units are sufficiently isolated to guarantee the required security, but utilize available resources efficiently, as they run on the same kernel.

OpenVZ

  • OpenVZ is container-based virtualization for Linux. OpenVZ creates multiple secure, isolated Linux containers (otherwise known as VEs or VPSs) on a single physical server enabling better server utilization and ensuring that applications do not conflict. Each container performs and executes exactly like a stand-alone server; a container can be rebooted independently and have root access, users, IP addresses, memory, processes, files, applications, system libraries and configuration files.

Docker

  • Docker is an open-source engine which automates the deployment of applications as highly portable, self-sufficient containers which are independent of hardware, language, framework, packaging system and hosting provider.
  • dockerlite lets you run Linux apps in lightweight, isolated environments, using LXC (Linux Containers). Using BTRFS snapshots, dockerlite can save the state of a given environment in a frozen "image", and later, create more environments ("containers") out of that image.

CoreOS

  • CoreOS is Linux for the container world. Linux kernel + systemd. That's about it. CoreOS has just enough bits to run containers, but does not ship a package manager itself. In fact, the root partition is completely read-only, to guarantee consistency and make updates reliable. Use docker as a package manager to build and push your app. The primitive of an application is a container, not a one-off package. Build containers using docker, by hand, or however you see fit! [3]

Juju

  • Juju enables you to use Charms to deploy your application architectures to EC2, OpenStack, Azure your data center and even your own Ubuntu based laptop. Moving between environments is simple giving you the flexibility to switch hosts whenever you want — for free.

  • Packer is a tool for creating identical machine images for multiple platforms from a single source configuration.

Management

OpenStack

  • Nova is the project name for OpenStack Compute, a cloud computing fabric controller, the main part of an IaaS system. Individuals and organizations can use Nova to host and manage their own cloud computing systems. Nova originated as a project out of NASA Ames Research Laboratory.
  • Glance provides services for discovering, registering, and retrieving virtual machine images. Glance has a RESTful API that allows querying of VM image metadata as well as retrieval of the actual image.
  • Swift is a highly available, distributed, eventually consistent object/blob store. Organizations can use Swift to store lots of data efficiently, safely, and cheaply.
  • Cinder provides an infrastructure for managing volumes in OpenStack. It was originally a Nova component called nova-volume, but has become an independent project since the Folsom release.
  • Neutron (was Quantum) provides "networking as a service" between interface devices (e.g., vNICs) managed by other Openstack services (e.g., nova).
  • Keystone is the identity service used by OpenStack for authentication (authN) and high-level authorization (authZ). It currently supports token-based authN and user-service authorization. It has recently been rearchitected to allow for expansion to support proxying external services and AuthN/AuthZ mechanisms such as oAuth, SAML and openID in future versions.

OpenNebula

  • OpenNebula.org is an open-source project developing the industry standard solution for building and managing virtualized enterprise data centers and enterprise private clouds.
    • OpenNebula is an open-source cloud computing toolkit for managing heterogeneous distributed data center infrastructures.

Fabric

Capistrano

  • Capistrano is a utility and framework for executing commands in parallel on multiple remote machines, via SSH. It uses a simple DSL (borrowed in part from Rake) that allows you to define tasks, which may be applied to machines in certain roles. It also supports tunneling connections via some gateway machine to allow operations to be performed behind VPN's and firewalls. Capistrano was originally designed to simplify and automate deployment of web applications to distributed environments, and originally came bundled with a set of tasks designed for deploying Rails applications.

Synapse

Continuous process

"Continuous Integration is a software development practice where members of a team integrate their work frequently, usually each person integrates at least daily - leading to multiple integrations per day. Each integration is verified by an automated build (including test) to detect integration errors as quickly as possible. Many teams find that this approach leads to significantly reduced integration problems and allows a team to develop cohesive software more rapidly."
