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 discussions that began at Structure 09: Last week I attended Structure 09, one of the better cloud computing conferences. Everyone I could hear the echo of the need for a service catalog; often it was implicit. For example, everyone spoke about the need for standardization and multi-tenancy, about the need to abstract computing resources from the application to enable moving workloads as needed.  Which in my mind requires you to a) know what the workload is, b) ...

Amazon Makes the Cloud Sticky

Stateless applications may be the long term answer to scalability of applications in the cloud, but until then, we need a solution like sticky sessions (persistence) Amazon recently introduced “stickiness” to its ELB (Elastic Load Balancing) offering. I’ve written a bit about “stickiness”, a.k.a. what we’ve called persistence for oh, nearly ten years now, before so I won’t reiterate again but to say, “it’s about time.” A description of why sticky sessions is necessary was offered in the AWS blog announcing the new feature: Up until now each Load balancer had the freedom to forw...

Can You Teach an Old Developer New Tricks?

When SOA was declared dead there was a spate of articles and blogs on why the architecture “died.” Most pundits came to the conclusion that like many innovations it wasn’t the technology to blame but rather people. Architects lacked the skills to properly leverage SOA; business  stakeholders failed to look at SOA as a strategic architecture, choosing instead to use it as a tactical integration-solving solution; network and systems’ administrators did not understand the unique characteristics and issues a well-designed SOA raised within the network and on systems; and developers w...

Dev and Production | @DevOpsSummit #DevOps #SDN #ContinuousDelivery

The Importance of Licensing to Equalize Dev and Production We’re all aware that dev/test != production environments. While the software stacks upon which applications are deployed may be (and hopefully are) the same, there still remains a whole lot of “infrastructure” (that’s everything else) that isn’t the same. Routers, switches, security devices, load balancers, caches, and other devices dedicated to ensuring the secure delivery of applications to hungry consumer and corporate users simply don’t exist in the dev/test environment. That’s particularly true as organizations cont... (more)

The Virtual Public-Private Cloud Connection

Secure, optimized tunnels to a remote site, e.g. the cloud. Haven’t we been here before? In the continuing discussion around Business Intelligence in the cloud comes a more better (yes I did, in fact, say that) discussion of the reasons why you’d want to put BI in the cloud and, appropriately, some of the challenges. As previously mentioned, BI data sets are, as a rule, huge. Big. Bigger than big. Ginormous, even. One of the considerations, then, if you’re going to leverage a cloud-based business intelligence offering – or any offering in which very, very large data sets/files a... (more)
