Appistry recently announced a new version of its service-enabling platform for high-volume data and transaction processing. Appistry Enterprise Application Fabric (EAF) version 3.7 includes a new performance-enhancement feature called "Affinity" that allows applications to better scale in a service-oriented architecture (SOA).
EAF works across multiple computers in grid implementations, and the Affinity feature helps find data and run it on the associated machine, which improves overall system performance. It can partition data within an application fabric and cache dynamic data for quicker access.
The Affinity capability was developed by Appistry as it worked with GeoEye, a provider of satellite imagery that is used in clandestine programs and in MSN's Virtual Earth map service. GeoEye also provides satellite photos to the press.
"Affinity allows you to bring the data closer to the application and have that data live within a fabric," said Sam Charrington, Appistry's vice president of product management and marketing. "As a service request comes in to find the [GeoEye] image, Affinity can find that image on the exact machine, and the work can happen on that machine without moving the image around."
Affinity's Fabric serves customers with extreme transaction processing needs, as exemplified by GeoEye. The satellite-imaging company processes lots of data, and it is planning to launch its highest resolution earth-imaging satellite next spring. GeoEye's new satellite cameras will be capable of resolving a distance that's less than half a meter in length, Charrington said. Each of the images (about 20 gigabytes in size) will cover an area that's about the size of Texas, and the satellite will produce about five terabytes of data every single day.
While GeoEye may have the world's best photogrammetrists (image-processing experts), the company needed help on IT, Charrington said. Things like the OS-level programming and building out applications for multithreading, as well as distributed computing -- that stuff is hard for them, Charrington said, "and these guys are literally rocket scientists."
Appistry's EAF enables SOAs using grid computing, but the Fabric works differently than an enterprise service bus in an SOA.
"The way to think about a fabric and a bus is that a bus is communications infrastructure, but it doesn't really do a lot for the endpoints," Charrington explained. "And we are a platform for building the endpoints. So a bus will help you connect your services together, and we will help you build the services."
Appistry's technology features "scale-out virtualization," which lets developers and operators see the fabric connecting a grid of computers as one thing.
"The developer who is developing an application that is going to run on the fabric doesn't need to think about all of the traditional distributed computing issues -- which are the most complex issues in the development realm," Charrington said. "They simply develop their application as if it's going to run single-threaded on a single computer, and the fabric software virtualizes that application out across as many computers that are required for their needs -- it could be 10 or it could be hundreds."
Sentrigo Inc. released its new Hedgehog vPatch database security software product Tuesday. The product addresses patching inconsistencies that seem to affect busy Oracle database administrators (DBAs), who don't always have time to test and patch. However, users of Microsoft SQL Server database in the enterprise can take a lesson here too.
Software provider Starfish Retention Solutions has announced the upcoming launch of its first product, Starfish Office Hours. The company said this will be the first in a series of products intended to help higher education institutions improve retention and graduation rates by aiding in the delivery of programs designed to help at-risk student populations.
Unisys announced Monday that it is offering companies a free 30-day unified communications trial using Microsoft solutions. The offer is currently available through Microsoft's sales personnel.
As part of its Innovative Digital Education and Learning initiative (IDEAL-NM), New Mexico is launching a statewide program to standardize on a single electronic learning platform--Blackboard--spanning K-12, higher education, adult education, and government. The initiative will also support a new statewide virtual high school.
The University of North Carolina and the North Carolina Community College System have signed on with Blackboard to deploy that company's electronic learning platform across 68 individual campuses.
Semantics is a sub-field of linguistics that focuses on meaning making in language. Therefore, the Semantic Web we're still reaching for will be based on a set of definitions, languages, and standards that can base a search on the detection of meaning and not just on a simple character string. The Semantic Web will at least be smarter than the current Web.
