The Rubik’s Cube of IT

Rubik’s Cube was first patented in 1974. The first book talking about a solution algorithm was published in 1981. In 2007, computers were used to deduce the smallest number of moves to solve a cube, and in  2008 that number was further... Read more

Jedi Mind Tricks: HTTP Request Smuggling

How to defeat the ancient Jedi mind trick known as HTTP Request Smuggling.  HTTP Request Smuggling (HRS) is not a new technique; it's been around since 2005. It takes advantage of architectures where one or more intermediaries (proxies)... Read more

OVF: A few layers short of a full stack

OVF (Open Virtualization Format) apparently just isn’t getting enough mindshare out there in the discussions of cloud computing that focus on portability and interoperability. The goal of OVF is to provide a portable, interoperable non-vendor... Read more

Control, choice, and cost: The Conflict in the Cloud

One of the oft cited reasons in surveys that enterprises aren’t flocking to the cloud like lemmings off a cliff is “lack of control”. Problem is that articles and pundits quoting this reason never really define what that means. After all, cloud... Read more

Cloud Strategy: Apathy or Architecture?

What’s driving your organizational interest in cloud? Is it apathy or is it architecture? The whole debate surrounding the existence, or non-existence as it were, of “private” clouds seems to revolve around the definition of cloud. Yes, we’re... Read more

Cloud Fail: Who and How is more important than What and Where

According to the definition of cloud computing used by Avanade for a recently released and often cited study on the use of cloud computing, I could claim to be a cloud computing provider. And so could you. Basically, so could just about everyone... Read more

Dynamic Infrastructure: The Cloud within the Cloud

When folks are asked to define the cloud they invariably, somewhere in the definition, bring up the point that “users shouldn’t care” about the actual implementation. When asked to diagram a cloud environment we end up with two clouds: one... Read more

Interoperability between clouds requires more than just VM portability

The issue of application state and connection management is one often discussed in the context of cloud computing and virtualized architectures. That's because the stress placed on existing static infrastructure due to the potentially rapid... Read more

More on the Meta-data Menagerie

Rich Miller, in response to some questions I maintain on meta-data ownership and interoperability with regards to the CCIF's efforts in defining a cloud interoperability specification, had some questions of his own: The part I'm... Read more

Who owns application delivery meta-data in the cloud?

While the vast majority of folks are still debating what is or is not "cloud computing", there are already groups trying to get ahead of the curve by focusing on broader issues such as interoperability and portability. Indeed, by... Read more

Infrastructure 2.0: As a matter of fact that isn't what it means

We've been talking a lot about the benefits of Infrastructure 2.0, or Dynamic Infrastructure, a lot about why it's necessary, and what's required to make it all work. But we've never really laid out what it is, and that's... Read more

Load balancing is key to successful cloud-based (dynamic) architectures

Much of the dialogue today surrounding cloud computing and virtualization is still taking the 50,000 foot view. It's all conceptual; it's all about business value, justification, interoperability, and use cases. These are all good... Read more

The Dynamic Infrastructure Mashup

Infrastructure 2.0 is, at its core, about evolving to a new level of interconnectedness, one in which the underlying infrastructure becomes as flexible and adaptable as the applications and virtualization infrastructure it is responsible for... Read more

What's good for the network is not always good for applications

Just because you can, doesn't mean you should. I'm going to start this one by quoting Hoff who was quoting Andreas Antonopoulos of Nemertes Research Group who was paraphrasing a concept put forth by Doug Gourlay. From Rational... Read more

Managing Virtual Infrastructure Requires an Application Centric Approach

Thanks to a tweet from @Archimedius, I found an insightful blog post from cloud computing provider startup Kaavo that essentially makes the case for a move to application-centric management rather than the traditional infrastructure-centric... Read more

Cloud Computing: Achieving full interconnectedness

The saying goes that to forget (or in some cases blatantly ignore) the mistakes of the past is to be doomed to repeat them. ODBC. BPEL. JDBC. All three are extensible standards in the software industry that cause no end of headaches and... Read more

Cloud Computing: What's stopping service-oriented clouds?

Whenever there is a shift in architectural thinking about technology, such as is happening right now with cloud computing and virtualization, we start thinking forward, past the now, and into the future about how that technology might be... Read more

Why you should not use clustering to scale an application

It is often the case that application server clustering and load-balancing are mistakenly believed to be the same thing. They are not. While server clustering does provide rudimentary load-balancing functionality, it does a better job of providing... Read more

Cloud Computing: The Last Definition You'll Ever Need

The VirtualDC has asked the same question that's been roaming about in every technophile's head since the beginning of the cloud computing craze: what defines a cloud? We've chatted internally about this very question, which led to... Read more

Cloud Computing: It's the destination, not the journey that is important

How the cloud acts and is used is more important than where it physically resides Cloud computing and SOA suffer from the same lack of prescriptive architectures. They are defined by how they act rather than what they are, or from what they are... Read more

Infrastructure 2.0: The Feedback Loop Must Include Applications

Greg Ness calls it "connectivity intelligence" but it seems that we're really talking about is the ability of network infrastructure to both be agile itself and enable IT agility at the same time. Brittle, inflexible infrastructures... Read more
