Can the inherent abstraction of virtualization succeed where SOA did not?
My first read through a post on the Cloud Front Office led me to scoff disdainfully at the re-emergence of a concept central to a successful SOA implementation: the service catalog. Oh, we called it "registry" and then "registry/repository (reg/rep)" and finally "governance" but the concept behind it was exactly the same. Take a gander at the description of a cloud service catalog apparently growing out of discus...

The importance of stress-testing in production
Everyone is still a-twitter over the problems the web experienced last week right after the news of Michael Jackson’s death. There have been
numerous stories on the fact that the Internet nearly fell over itself and died under the strain of trying to support the rush of millions of users as they queried, clicked, watched video, read blogs and news reports on the subject.
The Internet itself, of course, was just fine. The infr...

The concept of an “intercloud” is floating around the tubes and starting to gather some attention. According to Greg Ness you can “Think of the intercloud as an elastic mesh of on demand processing power deployed across multiple data centers. The payoff is massive scale, efficiency and flexibility.”
Basically, the intercloud is the natural evolution of global application delivery. The intercloud is about delivering applications (services) from one of many locations based on a variety o...

Somebody has to be first
Recently Microsoft came up with a solution, supported natively in IE8, to protect against clickjacking attempts. Apparently some folks have decided that because Microsoft has a history of implementing proprietary solutions that this one, too, must be proprietary. These same folks must also have very little understanding of today’s web application architectures, as they declared the solution pretty much useless based on some pretty poor assumptions regarding the...

I was chatting with my mother a couple weeks ago about cloud (she’s a used-to-be programmer turned project manager for a Fortune 500. Don’t look at me like that, I keep telling you it runs in the family) and one of the problems she lamented about was that folks don’t seem to understand how entrenched COBOL and the mainframe is in the organization. It’s so entrenched that given the choice between a client-server application and a COBOL application that did the same thing they chose the COBOL prog...

Whether you are aware of it or not, if you’re deploying applications in the cloud or building out your own “enterprise class” cloud, you’re going to be using load balancing. Horizontal scaling of applications is a fairly well understood process that involves (old skool) server virtualization of the network kind: making many servers (instances) look like one to the outside world. When you start adding instances to increase capacity for your application, load balancing necessarily gets ...

But browser support is only half the solution, don’t forget to implement the server-side, too.
Clickjacking, unlike more well-known (and understood) web application vulnerabilities, has been given scant amount of attention despite its risks and its usage. Earlier this year, for example, it was used as an attack on Twitter, but never really discussed as being a clickjacking attack. Maybe because aside from rewriting applications to prevent CSRF (adding nonces and validation of the same...
