The Virtualization Practice

The OpenStack conference 2012 is full of OpenStack fans, aficionados, developers, and companies making a business using the ecosystem. However, I kept hearing that openstack was a replacement for VMware. So why is this even a possibility, and why did Rackspace and now HP build public clouds using this technology? The easy answer is to save money. But is that the only answer? What is OpenStack and why is it becoming important?

While at InfoSec World 2012′s summit on Cloud and Virtualization Security, the first talk was on Securing your data. The second was on penetration testing to ensure that data was secure. In essence it has always been about the data but there is a huge difference between what a tenant can do and what the cloud or virtual environment provider can do with respect to data protection and security. This gap is apparently becoming wider instead of smaller as we try to understand tenant vs cloud provider security scopes. There is a lack of transparency with respect to security, but at the same time there are movements to gain that transparency. But secret sauces, scopes, legislation, and lack of knowledge seem to be getting in the way.

Data Protection techniques should be implemented and tested long before they are needed. This is a necessary component of any IT organization. However, the most recent communities podcast brought to light several implementation aspects of Data Protection, specifically about Disaster Recovery: organizations still do not test their DR plans and organizations are waiting for a hardware refresh to implement a DR plan.

Data Protection is still an issue with many small businesses and smaller enterprises who virtualize; Specifically around the Data Protection Process and eventually where to store the data. When I speak to people they are struggling with whether or not to place the data on tape, blu-ray, into the cloud, or other disks. Medium and Large Enterprises already have such policies in place, but like everything else, when they virtualized the policies may have fallen by the road side and now need to be recovered, dusted off, and put into practice. The choice of where the data will ultimately reside when disaster strikes is an ongoing discussion in the virtualization community. Ultimately, Data Protection is just that, protecting the data from loss, destruction, and allowing for quick recovery.

Over the last few months an additional subproject codenamed Quantum has emerged which deals explicitly with networking and has particpation from networking giants Intel and Cisco as well as from Citrix. It’s a mechanism for defining network topologies aimed at providing Layer-2 network connectivity for VM instances running in clouds based on the OpenStack cloud fabric. It is designed to be extensible to allow higher-level services (VPN, QoS, etc) to be built on top, and to cleanly handle the “edge of network” problem (i.e. the binding of the cloud into the internet).
