JANUARY 8, 2014 02:00 PM EST When we talk about the impact of BYOD and BYOA and the Internet of Things, we often focus on the impact on data center architectures. That's because there will be an increasing need for authentication, for access control, for security, for application delivery as the number of potential endpoints (clients, devices, things) increases. That means scale in the data center. What we gloss over, what we skip, is that before any of these "things" ever makes a request to access an application it had to execute a DNS query. Every. Single. Thing. Maybe that's because we assume DNS can handle the load. So far it's done well. You rarely, if ever, hear of disruptions or outages due directly to the execution of DNS. Oh, there has been some issues with misconfiguration of DNS and of exploitation of DNS (hijacking, illicit use in reflection attacks, et... (more)

Finding New Life For SOA in the Cloud

We’ve been having quite a few discussions with analysts over the past few months on the subject of “cloud”. The interesting thing about these discussions is the vast array of points of view from which those analysts are viewing “cloud”. Some are focused on the network aspects, others on pricing/differentiation, and some are even very focused on what “cloud” means to applications – and the organizations that will, allegedly, take advantage of the cloud as a means of application deployment. One such analyst is Daryl Plummer of Gartner. Daryl has always been very application focuse... (more)

Cloud Balancing, Reverse Cloud Bursting, and Staying PCI-Compliant

One of the concerns with cloud bursting specifically for the use of addressing seasonal scaling needs is that cloud computing environments are not necessarily PCI-friendly. But there may be a solution that allows the application to maintain its PCI-compliance and still make use of cloud computing environments for seasonal scaling efficiency. Cloud bursting, a.k.a. overdraft protection, is a great concept but in some situations, such as those involving PCI-compliance, it can be difficult if not impossible to actually implement. The financial advantages to cloud bursting for orga... (more)

Management and Orchestration | @DevOpsSummit #DevOps #Microservices

Early (very early, in fact) in the rise of SDN there were many discussions around scalability. Not of the data plane, but of the control (management) plane. Key to this discussion was the rate at which SDN-enabled network devices, via OpenFlow, could perform “inserts”. That is, how many times per second/minute could the management plane make the changes necessary to adjust to the environment. It was this measurement that turned out to be problematic, with many well-respected networking pundits (respected because they are also professionals) noting that the 1000 inserts per secon...

Governance: Service Catalogs and the Cloud

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 serv... (more)
