Why Choose DDS ?
WHY CHOOSE DDS ?
PERFORMANCE , SCALABILITY , ROBUSTNESS , AND QOS FOR INDUSTRIAL IOT AND CONSUMER IOT
The OMG DDS standard is a perfect fit for both the Industrial Internet of Things and large-scale Consumer IoT applications . It is already well-proven in mission-critical systems in industries ranging from smart transportation to healthcare to smart energy .
IS DDS RIGHT FOR YOU ?
Based on the use of DDS in thousands of applications , we can predict the need for DDS in new projects . If you answer “ yes ” to all of the following questions , DDS is likely to be your go-to solution .
• Do you have latency , network bandwidth / throughput , or scaling issues because you measure latency in ms or less , or you have more than 10 different applications , or you have more than a thousand data items to share ?
• If your system goes offline for 5 minutes ( or even 5 ms ), is it a serious problem ? Or , do you struggle to configure , startup , or failover to backup servers ?
• Are you building a system that will take more than a year to write , last more than three years , and is expected go through multiple versions or integrate with legacy applications ?
These questions help identify your critical performance , reliability , and integration needs . If you answer yes to any of these questions , you should evaluate DDS as a solution , since it offers many additional benefits .
KEY ADVANTAGES OF CHOOSING DDS
The OMG DDS middleware standard helps users reliably and securely harnesses ever-increasing amounts of device-generated data while processing the data in real-time , and acting on events as quickly as they occur . As a result , it enables smarter decisions , new services , additional revenue streams , and reduced costs . The OMG DDS middleware standard can also simplify the development , deployment , and management of IoT applications , speeding time-to-market . It provides :
• Ease of Integration : The data-centric approach used by DDS allows the definition of common and extensible data models for seamless Information Technology ( IT ) / Operational Technology ( OT ) interoperability . Its loose and anonymous data-sharing abstraction completely hides connectivity and topology details from applications .
• Performance Efficiency and Scalability : DDS implementations can achieve point-to-point latencies that are as low as 30 µ sec . and throughput of several million messages per second . It uses a very efficient wire protocol , content- and time-based filtering . When properly architected , DDS-based systems can achieve near-linear scalability .
• Advanced Security : The OMG DDS Security Specification defines a comprehensive Security Model and Service Plugin Interface ( SPI ) architecture for compliant DDS implementations . DDS provides standardized authentication , encryption , access control and logging capabilities to enable secure data connectivity end-to-end in an IoT system .
• Open Standard : The OMG DDS middleware specification is a mature , proven standard open to participation by both vendors and users . It enables end-to-end vendor interoperability and eases IoT system development and integration through fully open , future-proof APIs with no vendor lock-in .
• QoS-Enabled : A rich set of QoS policies allows DDS to control all aspects of data distribution , such as timeliness , traffic prioritization , reliability and resource usage .
• Scalable Discovery : For large-scale dynamic systems , DDS offers automatic discovery that provides plugand-play functionality to simplify system integration and orchestration .
• Applicability : DDS can transparently address peer-to-peer , device-to-device , device-to-cloud , and cloudto-cloud communication . Implementations are available for embedded , mobile , web , enterprise and cloud applications .
