Infrastructure 2.0 ≠ cloud computing ≠ IT as a Service. There is a difference between Infrastructure 2.0 and cloud. There is also a difference between cloud and IT as a Service. But they do go together, like a parfait. And everybody likes a parfait… The introduction of the newest member of the cloud computing buzzword family is “IT as a Service.” It is understandably causing some confusion because, after all, isn’t that just another way to describe “private cloud”?  No, actually it isn’t. There’s a lot more to it than that, and it’s very applicable to both private and public models. Furthermore, equating “cloud computing” to “IT as a Service” does both a big a disservice as making synonyms of “Infrastructure 2.0” and “cloud computing.” These three [ concepts | models | technologies ] are highly intertwined and in some cases even interdependent, but they are not th...

DNS Is Like Your Mom

Both are taken for granted but provide vital services without which you and your digital presence would be lost. In the case of DNS, that should be taken literally. Mom. She’s always there, isn’t she? She kissed away your bumps and bruises. You treated her like Google before you had access to the web and, like Google, she came through every time you needed to write a report on butterflies or beetles or the pyramids at Giza. You asked her questions, she always had an answer. You didn’t spend as much time with her as you grew older (and discovered you knew way more than she did, d... (more)

The Encrypted Elephant in the Cloud Room

Anyone who’s been around cryptography for a while understands that secure key management is a critical foundation for any security strategy involving encryption. Back in the day it was SSL, and an entire industry of solutions grew up specifically aimed at protecting the key to the kingdom – the master key. Tamper-resistant hardware devices are still required for some US Federal security standards under the FIPS banner, with specific security protections at the network and software levels providing additional assurance that the ever important key remains safe. In many cases it’s ... (more)

Doing VDI, Only Better

There are three core vendors and protocols supporting VDI today. Microsoft with RDP, Citrix with ICA, and VMware with PCoIP. For most organizations a single vendor approach has been necessary, primarily because the costs associated with the supporting network and application delivery network infrastructure required to deliver VDI with the appropriate levels of security while meeting performance expectations of users and the need to maintain high availability. It’s a tall order that’s getting taller with every mobile client introduced, especially when you toss in a liberal dose o... (more)

Dear Slashdot: You Get What You Pay For

Open Source SSL Accelerator solution not as cost effective or well-performing as you think o3 Magazine has a write up on building an SSL accelerator out of Open Source components. It's a compelling piece, to be sure, that was picked up by Slashdot and discussed extensively. If o3 had stuck to its original goal - building an SSL accelerator on the cheap - it might have had better luck making its arguments. But it wanted to compare an Open Source solution to a commercial solution. That makes sense, the author was trying to show value in Open Source and that you don't need to shel... (more)
