When it comes to building a fully operational ecosystem, a good network of integrations is essential. Integrations can be built in either a point-to-point fashion, where every system is directly connected to every other system, or in a pub-sub model.
A point-to-point integration is a pattern where data is published from one software tool directly to another. This is commonly accomplished by either the two tools having a supported integration (for example Hubspot’s integration with Magento) or a third-party tool such as Zapier.
When an integration layer is built, many systems are connected to each other through a central platform. They communicate to each other using a publication-subscription pattern in place of a standard messaging queue. Source systems publish information to relevant topic boards; other sources that are interested in getting information from the source systems can subscribe to those topics. When a publisher updates the topic, that information is immediately pushed out to all the subscribers.
When developing an integration layer, there is a bit more to build out. It requires infrastructure to run on top of, which means you need to manage said infrastructure and that it will be longer process to set up. But that extra work earns you a lot of pay off.
An integration layer enables the ability to take advantage of the full integration functionality of any third-party or custom tool, meaning you can shape your integrations around your business processes
An integration layer becomes a centralized area where all data in your system flows. This means that you have a central place to perform analytics, reporting, and build new products on top of all of your data
The beauty of the pub-sub model is that connecting new systems is incredibly easy. Nothing in your existing ecosystem has to be changed, and there is only one connection that needs to be made. And because it is custom built and can include an implementation detail we call a facade, there is no concern that the system won’t mesh with what you need it to connect to. Adding new use-cases has never been faster!
A key feature of the pub/sub model is that any system subscribed to receive notifications from another system will get notified about any updates without having to ping the source system for frequent checks. It is a one way flow of information that goes out to all subscribers in one push.
For any business interested in scalability, using an integration layer and pub-sub messaging patterns opens up a world of potential. The alternative of a growing network of point-to-point integrations becomes such a mess web of closely coupled systems. For a little more upfront work, your company will save a great deal of time getting new systems up and running once this new infrastructure is established, which to us is a no-brainer.
