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 µsec. 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,
