According to Gartner’s Yefim V. Natis, VP & Fellow, a new enterprise architectural style is rising these days: Software-Defined Architecture (SDA).During the Gartner webinar entitled Software-Defined Architecture: Application Design for Digital Business (account required), Natis took a look at the challenges that modern IT presents to software architects and some of the design principles that help architects create better applications that last longer. Among other things discussed during this webinar, Natis introduced this idea of SDA as a natural development in software architecture following previous styles starting with the monolithic one of the 70s as depicted in the next graphic taken from the webinar’s slides (PDF): Source: A New Style Is Emerging in the Enterprise: Software-Defined Architecture
In the US alone, smart meters have been deployed to 4.6M commercial and industrial (C&I) customers, according to the Energy Information Administration. This represents only 11% of total deployment, but these smart meters serve nearly 340M megawatt-hours (MWh), making up 49% of all energy served by total advanced metering infrastructure (AMI) installed. [..] With these extensive deployments comes a high cost. Total capital costs per meter, including installation, range from $81 to $532, according to Siemens, and when multiplied by a million or so meters, costs can quickly inflate. One way utilities are accelerating their smart meter ROI is by using the AMI data to deliver shared utility-customer value, particularly for C&I customers. Source: Who Owns the Data? – EnerNOC Blog
Energeya offers a full suite for energy and commodity trading floors. This package is used in a number of companies in southern Europe, mainly Italy. One North European company is currently migrating to this package. The product that Energeye offers is based on an open source stack of standard components that deliver the basic functionality. On top of this stack is where the business logic is located that is developed in house. All of the most important commodities appear to have been covered; Each commodity comes as a separate pacakge on top of standard packages. No pricing is shown, but I would assume that it comes a whole lot cheaper than an OpenLink based applciation deployment.
