Since the dawn of time and human communication and collaboration has played a very crucial role in the day-to-day activities of anything to be achieved, this would be done through verbal or written messages that play the role of data transfer from one person to another. Back to today's messaging patterns in real-time systems, there's little that compares to the simplicity of publishing/subscribing. The pattern has been creeping around since the days of the telegraph and is still used today in everything from stock exchanges to online gaming platforms. This seemingly simple architecture relies on a real-time messaging infrastructure to distribute messages across a network using a publish/subscribe model. A publisher sends messages (or publishes) out into the system, while subscribers receive them (or subscribe). Publishers and subscribers don't need to know about each other; they have no direct connection. What if you could take this simple pattern one step further? What if you could provide your clients with tools that would give them access to more than just messages? What if those tools provided insights into their data? You can do all this with Data Distribution Service (DDS). DDS is an object-oriented middleware standard from OMG that helps you build systems based on publish/subscribe messaging patterns. It provides APIs for sending and receiving messages and managing subscriptions and event notifications. DDS is like the internet because it has many different applications. The difference is that DDS provides scalable, high-performance and real-time interaction for publishers and subscribers. It eliminates the need for network programming that handles communications, as all connected nodes and applications rely heavily on DDS, which automates their interaction. If you're looking to do something massive that can actually build an entire city or a giant robot, you should keep a keen eye on DDS.
