While participating in the GestaltIT Virtualization Field Day #2, I was asking PureStorage on whether or not SSD based storage was throwing hardware at a problem that is better fixed, by changing the code in question? What brought this thought to mind was the example used during the presentation which was about database performance. This example, tied to a current consulting problem, where fixing the database improved performance by 10x. This alleviated the need for over all storage improvements. So the question remains, is using SSD, throwing hardware to solve a basic coding problem?
While participating in the GestaltIT Virtualization Field Day #2, I was asking Symantec about Application Aware Backups. In other words, could one backup an entire application, regardless of how the application was defined. This concept goes hand in hand with Application Aware Security measures. We can always backup VMs and their data to remote locations, but can we backup or maintain the application interactions within a multi-VM Application regardless of how it is defined.

Virtualization and Cloud Security architects, pundits, and writers like myself often talk about protecting the data within the virtual and cloud environments. However, in order to protect that data we need to be able to determine how the data will be used, accessed, modified, and eventually removed. So, how can we understand data security without understanding the application around it. But there is an even more fundamental problem, how do we define the application and the security measures we should take?
The 2/9 Virtualization Security Podcast was a discussion on when would one use a virtual firewall. This was in response to being told that there are some people that would never use a virtual firewall for anything, and that got me thinking. Outside of the politics involved with using virtual vs physical firewalls, when would you use one? What are the cut offs, and best practices around using virtual firewalls. We were joined by Rob Randell of VMware to discuss this point.
I and others look at Virtualization Security constructs with an eye towards Cloud Security, but they are not necessarily the same. Granted for some clouds, virtualization security can lead to cloud security but this really depends on how the cloud’s architecture. Even so, what we know from Virtualization Security WILL apply to Cloud Security and will be the basis for best practices. But you say, my cloud does not use Virtualizaiton? Ah ha, I say, but it is still a cloud? And that implies there are similar security concerns. This was the discussion on the 1/26 Virtualization Security Podcast.
When you read many blogs and articles on cloud security, writers such as myself often mention jurisdictional issues as a big problem. Nor is the ability to Audit clouds the only problem. Yet both of these are huge issues for clouds today, but fundamentally, is the cloud flawed from a security point of view or are there plenty of security mechanisms available?
One of the questions I get from time to time is, can I store my data in the cloud? At the NEVMUG, this came up once more. There is currently a lot of uncertainty about cloud storage, specifically when it comes to critical and highly regulated data. Where should I store my data, dovetails nicely with discussions of going to the cloud as well as data protection is a key component of such a migration.
I was discussing yesterday how to use virtualization and cloud performance management tools as an early warning system for security issues. I have touched on use of New Relic, VMware vFabric APM, Quest vFoglight, and other tools that can make up such a early warning system before, but without the proper process in place, the tools will not be good enough.
At the end of last year and the beginning of this year the Virtualization Security Podcast featured two very different guest panelists to discuss cloud security, policy, and compliance: Phil Cox, Director of Security and Compliance at RightScale, joined us for the last podcast in 2011 and the George Gerchow of VMware’s Policy and Compliance Group, joined us for the first podcast of 2012. We asked is the public cloud ready for mission critical applications. The answer was surprising. Have a listen and let us know your thoughts.
