News: Citrix Acquires Cloud.com

Citrix has purchased Cloud.com and this poses some interesting changes to the overall virtualization and cloud markets. One also has to wonder about the timing of the announcement to coincide with the same day as the big announcements coming out of VMware. I see this purchase as a mixed blessing to the market place, but also a renewal for Citrix.

Start with SaaS Security: End with Data Security

The 6/30 Virtualization Security Podcast with Simon Crosby Founder and CEO of Bromium started with a discussion of SaaS security but soon went to a discussion of Data Security. Simon left Citrix not to long ago to form a new company, Bromium, to seriously look into how the hypervisor itself can provide better security for data manipulations than it does today. But first we started off with SaaS and how you can Identify the user within a cloud.

Replication Receiver Clouds: Protecting your Data

Security in the cloud and the virtual environment is ‘all about the data’ and not specifically about any other subsystem. It is about the data. As such the data has something it knows (the contents of the data), something it is (its signature), and something it has (its digital rights) and since it has these three elements, the data has all it has identity. However, protecting the data requires us to put things between the data and the real world such as firewalls, and complex role based access controls, as well as methods to replicate the data to other locations in a non-intrusive mechanism. The goal to such replication could be to ensure multiple sites have the same data (such as a hot-site) or to have the data available in another locations in case of disaster.

Virtualized Replication: vSphere APIs Expand

As a delegate for Tech Field Day 6 in Boston, I was introduced to SRM Replication as well as ZeRTO a third party replication tool. They seem to be as different as night and day but are they? Both work within the vSphere environment to replicate virtual disks regardless of storage type, and apparently hook into the same location within VMware’s API stack. This shows a maturity of VMware’s API stack that until now has been unknown and secret. In this one area, Microsoft Hyper-V is beating VMware vSphere: The availability of well known APIs that are easy for Third Parties to use. I now see a change in VMware’s behavior, can they continue this growth?

Where are my NOC Views: Virtualization Management Vendors

As a delegate for Tech Field Day 6 in Boston, I was introduced to many third party management tools. In the past I have been given briefings as well on various VMware, Hyper-V, and Citrix Xen Management Tools as well. Many of these tools are marketed directly for use by the administrator, but they have the tools can be used by more than the administrator. These tools should be marketed to management, administrators, as well as the network operations center (NOC). We need tools that perform continual monitoring and auditing so that we can know as soon as possible when a problem occurs.

Improving PaaS Security: Get your Developers Involved

The 6/16 Virtualization Security Podcast started as a twitter conversation with a comment about PaaS Security where James Urquhart, Krishnan Subramanian, Rich Miller, and myself went back and forth about PaaS security and the role of the developer. It was not quite a DevOps conversation but pretty close. Rich could not join us on this Podcast but hopefully will make a future one. PaaS security appears to be dependent on two things, the provider’s security, and how it is used.
