Data Protection is not just about backup these days, but instead concentrates on two all important concepts for a business: disaster recovery and business continuity. While backup is a part of Disaster Recovery, restoration is all important. If it is not possible to restore your data in a timely fashion the backup has failed. So technologies that allow us to access our data immediately provides a level of business continuity. But how is this achieved? So where do you save your critical data is is readily restorable? Is your backup integrated into your monitoring software? Have you tested your restore today?

As I was flying home recently, the gentleman beside me was talking about his need to do the “cloud thing” as a means to backup his data. He recently experienced a multi-retail shop backup failure where the local backup disk was corrupted and the backups failed to happen. I also experienced a backup failure, when my backup software was upgraded. In both cases, the backup software did not mail out, or alert the appropriate people of the failure. Even if the backups did work, the data was still corrupted. So the question is, how can cloud based backups help with either of these scenarios?

There has been quite a bit of hype on whether virtual desktops provide more security than traditional desktops. All the marketing literature I have read says that it does improve overall security, but I believe this marketing literature makes several assumptions that are just not true in most organizations, and really do not account for the myriad ways data can be accessed, by limiting our scope to just virtual desktops instead of the full desktop experience we are thereby limiting our thoughts on security. Are virtual desktops more secure?

I am not sure how other people have learned their craft and mastered the technology they support, but for me, the learning started after the books ended. I have learned so much more from breaking something and having to find the fix than I ever did from reading a book. Back in the day around 2005, VMware released The VMTN Subscription. This was an amazing program that was something like the Microsoft MSDN subscription. These programs gave you the ability to run any of the core software packages for a year at a time for a subscription fee.

The October conference schedule is now complete and it was a tough one but very rewarding. The events that happened in October were numerous and overlapping in some cases. Travel was one week here and the next week there, yet we managed to get through it. Of the mass of conferences, I attended two, IPexpo as a guest and The ExecEvent and Hacker Halted as a speaker. I discovered something very strange, virtualization and cloud security are merely after thoughts. I felt this should have changed by now, but alas this is not the case. Is it that our scope is incorrect, or is it that there is no Return on Investment on security tools, procedures, etc?

The Virtualization Practice was recently offline for two days, we thank you for coming back to us after this failure. The reason, a simple fibre cut that would have taken the proper people no more than 15 minutes to fix, but we were way down on the list due to the nature of the storm that hit New England and took 3M people off the grid. Even our backup mechanisms were out of power. While our datacenter had power, the rest of the area in our immediate vicinity did not. So not only were we isolated from reaching any clouds, but we were isolated from being reached from outside our own datacenter. The solution to such isolation is usually remote sites and location of services in other regions of a county, this gets relatively expensive for small and medium business, can the Hybrid Cloud help here?

There have been a large number of Announcements that have been made for VMworld Copenhagen with respect to virtualization and cloud security. This shows quite an interesting growth in the market, and that even 1 month apart there is still more to be announced within the virtual and cloud security spaces. There are three very interesting announcements that show further integration between vendors.

VMworld EMEA, IPExpo, The ExecEvent, Citrix Synergy, oh my!

This month (October 2011) there are a slew of conferences on virtualization and cloud technologies being held in Europe. The question becomes which to attend! If you are in the United States, this could be expensive considering the current Euro to Dollar exchange rate but if you are already in Europe one of these events is well worth attending, each has there own take and focus. But after the success of VMworld US, is there anything more to announce?
