Is Physics holding you back? Reply

One of the more interesting aspects of distributed application development is to be aware of the physics involved in the deployment. Any signal experiences a propagation delay resulting from the finite speed of light, which is about 300,000 kilometers per second, or 1 nanosecond per foot. While getting a faster middleware such as RTI Data Distribution Service is part of the solution, the comprehensive way to address this issue is by distributing the intelligence in the network. More…

Designing information models for distributed applications Reply

The technologists in edge environment spend significant time tuning the network links, but they often miss opportunities to make optimal use of available bandwidth by not focusing (enough) on tuning the data model. This (relative) lack of attention to the data model, while regrettable, can be better understood if we account that until recently, edge devices were weak (could not collect or process enough information), few (not choking the network, though bandwidth is always an issue), or not (richly) context-aware (taking advantage of other information available on the network) The science of tuning the information model for a distributed application can benefit from the advances in building information models for the enterprise applications.
