Virtualizing Business Critical Applications – A Reference Architecture

Virtualization Security, Configuration Management, Service and Capacity Management, Provisioning and Lifecycle Management, and Backup/Recovery are essential functions that must be added to a virtualization platform when virtualizing business critical applications. VMware vSphere is clearly the market leading and most robust virtualization platform – and clearly the virtualization platform most suitable as the foundation of a virtualization system designed to support business critical applications. However, the virtualization platform must be complemented with third party solutions in these areas in order to create a system that can truly support business critical applications in an effective manner.

Cloud and hosting providers are aggressively investing in new Intel Xeon servers that can have as many as 32 cores per server (4 processors with 8 cores per server). Some of this investment is in response to current demand for actual capacity from customers. Some of it is investing ahead of the curve so that the cloud vendor is properly positioned when the demand arrives. The growth and the hype in the cloud is such that there is highly likely to be an overbuild of capacity at some point and then a crash and a period of consolidation – just as there was with ASP’s and the .com companies.

Which is better – Virtual Desktop Infrastructure or Presentation Virtualization? If you have, say, a Citrix XenApp PV solution – you may may be tempted at the reduced cost per license of VDI – XenDesktop appears to be almost half the cost per user than XenApp. Maybe you’ve a VMware vSphere back-end and the thought of having one platform to manage is appealing. Maybe you have a different solution – perhaps Quest’s vWorkspace or Ericom’s Webconnect and are wondering what all this fuss about moving between PV and VDI is all about?

During the Virtual Thoughts podcast on 6/29/2010, the analysts discussed various hardware aspects of virtualization trying to determine if the hypervisor was to move into the hardware? and if so how much of it? as well as whose hypervisor? and lastly such a move part of any business model?

Virtual Thoughts is a monthly podcast that looks at the entire scope of virtualization to discuss new trends and thoughts within the virtualization and cloud communities.

This weeks podcast started with a discussion of TPM/TXT and the boost it gives to virtualization security. Since TPM/TXT is based in the hardware and provides a measured launch of an operating system, the next logical discussion was on whether or not the hypervisor would be placed into the hardware?

There is a cardinal rule that we should all know about, especially for those of us who have spent a lot of time developing kickstart scripts for automated builds of the VMware hosts in your environment, that you do not use windows word editors like Notepad or WordPad when working with Linux files. If you use notepad to edit Linux files it will add unwanted line feeds (LF) to the file which may cause the file to be misinterpreted. If you must use Microsoft Windows as your client OS use Microsoft WordPad which does not modify the file in this way.

VMware has already demonstrated a penchant for using open source technologies to fundamentally disrupt the value propositions for the products from competing vendors in the systems software and applications platform businesses. This has put the operating systems businesses at Microsoft and Red Hat, and the applications platform businesses at Microsoft, Red Hat, IBM and Oracle under pressure, by providing a cost effective and fully functional alternative to the traditional licensed software models of these companies. It is entirely possible that VMware will pursue the same approach in the management software industry thereby disrupting the business models and product positions of CA, IBM/Tivoli, HP, BMC as well as many of the vendors currently in the VMware ecosystem.

There is a great deal of marketing hype about which hypervisor is better but I have spent some thinking about this and really have to wonder if the hypervisor is what we should really be focusing or concentrating on. A lot of third party vendors are starting to port their products to be able to work with both hypervisors but what about the management server itself? When third party application vendors design their applications to work with VMware or Microsoft hypervisors they have been writing plug-ins for their product to work inside the management server systems and or its client.

Systems Management Frameworks have provided an indispensable function to enterprises with large and business critical networks and data centers. However, frameworks have become a category of expensive and slow to innovate legacy software leading many enterprises to conclude that they must move beyond these products in order to properly monitor their newest environments including those that are based on virtualization and public clouds. New virtualization and cloud focused tools are providing support for these environments that is not present in legacy management frameworks. Self-learning analytics may replace the frameworks as the “manager of managers” or new frameworks may emerge out of the open source movement.
