Debunking the "No Such Thing as A Private Cloud" Myth

_Once upon a time, a network engineer scrawled an amorphous shape upon a whiteboard and wrote “Internet” thereon.  The amorphous circle, a ‘cloud’, soon became the de facto way that we represent “not my problem”, or outsourcing.  Hence, the “cloud” in cloud computing means that cloud is predominantly an outsourcing...

Nicira & Citrix are Warming Up

Some exciting news on the open cloud front.  Nicira’s openvswitch (think: open source Cisco Nexus 1000V) made it in as the default vSwitch in the latest release of the Xen Cloud Platform.  For those who aren’t aware, the Xen Cloud Platform is an open source provider/cloud-focused management framework for clouds....

Cloudscaling on a Tear - 2009 in Review

We’re a little late in posting this due to the holidays, but I have some exciting stats to share with you.  In 2009 the Cloudscaling blog became one of the hottest destinations for cloud knowhow.  A big part of that success was our unique perspective on cloud computing.  We aren’t...

How Clouds Enable Global Reach

Over a year and a half ago, I mentioned that there were four key aspects to cloud computing: scalability, leverage, speed, and reach.  All of these still hold true today.  In particular, the one area that was underdeveloped was the notion of using clouds for global reach. As you know,...

More on Amazon's SAS70 Type II

Amazon hasn’t been forthcoming since my last post on their control and control objectives, which is disappointing, but expected.  I still believe that transparency here is more important than security through obscurity.  Hiding the controls and control objectives doesn’t provide much in the way of particular security benefits, although I’m...

Why is Amazon's SAS70 Audit Bogus?

At first glance it seems like Amazon’s recent announcement of a successful SAS70 audit is grounds for celebration[1]. Certainly it has met with fanfare on Twitter and blogs. Unfortunately, a SAS70 audit isn’t what most people think it is. Worse yet, Amazon’s reluctance to provide details of the audit provides...

State of the Cloud - Cloud Camp in the Clouds

I recently gave a short, 5-minute ‘lightning talk’ at Cloud Camp in the Clouds.  This is the first ‘virtual’ (online) event for the Cloud Camp folks.  I want to particularly thank the organizers Reuven Cohen, Dave Nielsen, and Sam Charrington for allowing me to give our perspective and also to let us...
