Enomalism Beta Program ¶ The Enomalism cloud computing platform currently in beta and is available to select Enomaly partners. Please enter tickets using the New Ticket link above. Full source code is available under Browse Source. What is Enomalism? ¶ Enomalism is an open source web-based virtual infrastructure platform. Designed to answer the complexity of managing globally disperse virtual server environments. Enomalism helps to automate the transition to a cloud computing environment by reducing an IT organizations overall workload. The easy to use dashboard can help with issues including deployment planning, load balancing, automatic VM migration, configuration management, and capacity diagnosis.

In this article, I briefly introduce the concepts of Xen virtualization and Linux clustering. From there, I show you how to set up multiple operating systems on a single computer using Xen and how to configure them for use with clustering. I should point out that a cluster implemented in this manner does not provide the computational power of multiple physical computers. It does, however, offer a way to prototype a cluster as well as provide a cost-effective development environment for cluster-based software. Even if you're not interested in clustering, this article gives you hands-on experience using Xen virtualization.

While consolidating physical to virtual machines using Xen,we want to be able to deploy and manage virtual machines in the same way we manage and deploy physical machines. For operators and support people there should be no difference between virtual and physical installations. Integrating Virtual Machines with the rest of the infrastructure, should have a low impact on the existing infrastructure. Typically, Virtual machine vendors have their own tools to deploy and manage virtual machines. Apart from the vendor lock-in to that specific virtual machine platform , it requires the administrators to learn yet another platform that they need to understand and manage, something we want to prevent. This paper discusses how we integrated SystemImager with Xen, hence creating a totally open source deployment framework for the popular open source Virtual Machine monitor. We will document both development of our tools and go more in depth on other infrastructure related issues when using Xen System Imaging environments in combination with Virtual machines can also be used to ensure safe production deployments. By saving your current production image before updating to your new production image, you have a highly reliable contingency mechanism. If the new production environment is found to be flawed, simply roll-back to the last production image on the virtual machines with a simple update command! Xen has become one of the most popular virtualisation platforms over the last year, although not such a young project, it is now rapidly gaining acceptance in the corporate world as a valuable alternative to VMWare.

The Enomalism Virtualized Management Dashboard (VMD) is a powerful web-based virtual server manager. Designed to answer the complexity of managing globally disperse virtual server environments. Enomalism helps to ease the transition to a virtualized environment by reducing an IT organizations overall workload. The easy to use dashboard can help with issues including deployment planning, load balancing, automatic VM migration, configuration management, and capacity diagnosis.

XenMan is an intuitive, graphical management tool aimed at operational lifecycle management for the Xen virtualization platform. XenMan is built on the firm design philosophy that ease-of-use and sophistication can, and should, co-exist in a single management tool. So, XenMan should hopefully prove valuable to both seasoned Xen Administrators as well as those just seeking an introduction to Xen Virtualization. With XenMan's secure, multi-node capabilities, administrators can safely manage their entire environment from a single, centralized console. Most common administrative tasks like starting/stopping/provisioning virtual machines (Guest OS's) typically involve just a few mouse clicks with XenMan; as do server management operations like scanning OS configurations or acquiescing individual servers for maintainance.
