An increasing number of applications, such as smart cities, mobile-health and smart grids, require to ubiquitously distribute and access real-time information from, and across, a vast variety of devices, ranging from embedded sensors to mobile devices. While the problem of ubiquity is solved at a computing and network connectivity level, it is by no means solved with respect to (1) real-time, and (2) resource efficient (e.g. battery life and network), data distribution. This webcast will unveil PrismTech’s “DDS Everywhere” product strategy and will introduces a series of Innovations that have extended the OpenSplice ecosystem to seamlessly share data between embedded devices, traditional IT infrastructures, cloud applications and mobile devices.

☐ With the DDS Everywhere platform we are making DDS available
on any device
☐ That means that:
☐ You can get DDS data from your system to anywhere
OpenSplice DDS
☐ You can exploit the power of DDS across devices and technologies
☐ You have a single technology end-to-end that provides optimal efficiency,
scalability, performance and more importantly data-centricity!
