Your challenge

(Micro) Services and Integrations

Don’t think Enterprise Integration is only about ESBs. It’s much more. To align all systems and applications within your company, you need a combination of tools. Think ESB, think microservices, think workflows. Confused? Read this page and all will be clear.

We’re fans of an API first strategy. Still, it’s crucial to integrate applications, data and business processes in your internal IT landscape. Here, microservices are the perfect way to enable single transaction management. But when it comes to the heavy lifting, you’ll always be needing an ESB. It’s the integration backbone that sets the standards and makes the rules! Let’s see what a great enterprise integration solution is made of.

Mapping and routing

This is a no brainer for people that know their integration, but still. Mapping and routing make sure the right messages are sent to the right place and at the right time, without creating a domino effect when something goes wrong. This makes them two main features of your integration solution, and therefore your digital transformation as a whole. Mapping and routing depend on CDMs: message translators that are implemented in your ESB.

Business rules

Your enterprise integration solution is your central meeting point between your applications. This makes it the best place in your IT landscape to implement your business logic. How should data be created? And how should it be edited and exchanged between your applications? The detailed logic will always be inside each single application, but the overall logic should be right where your data meets: in your middleware.

Adaptors and Connectors

Do you work with SAP, SalesForce, Google, AWS, Azure or a any other software stack? Then you need to connect them with your own software. A good enterprise integration solution therefore has plug-ins for all common software applications. This means you don’t have to build the connections yourself, which saves time and helps you speed up time to market. Speaking of agility!

Automation is a blast, but the fact remains that sometimes, a business process needs human interaction. Your enterprise integration tool should therefore know how to deal with both standardized data flows and human intervention. This calls for flexibility, which can be created with workflows. Integration workflows make sure that the show goes on, no matter the event, timing, data format or form of human support.


Finally, microservices! And you thought we wouldn’t mention them. Although we’re true believers of enterprise integration tools, we can’t deny that a microservices implementation is the way to go for single transaction management. They are your fire and forget whereas enterprise integration tools guard the overall processes. Together, they make the ultimate integration solution, so implement both and make them work together as a team.


When you follow an API first strategy, you collect all your info at your API gateway. At the same time, it’s important that you analyze the consumption and quality of your services at your ESB: the so-called second level of your integration. Whereas APIs collect data on who enters your systems and why, ESB analytics tell you more about the technical details and how your services perform.
