A very common specialism in CRM development is integration with other systems such as SAP and Exact, for example to keep contact and invoicing data synchronous, but also to enrich data in CRM with data from, for example, a postal code supplier, the land register, the insolvency register, and so on. In addition, it is also very common to link customer portals and all kinds of customized software to CRM.
These integrations are almost always done through web services which take care of the data transport from one system to another.
Microsoft Azure offers various tools to realize this. Most of the time we use a combination of Azure Service Bus with Azure Logic Apps, Azure Function Apps and/of Azure API management. These products integrate very nicely with Dynamics 365 CE/CRM.
Beside Azure solutions you may also choose for custom made integration software based on, for example, .NET Web API supplemented with Azure Service Bus.
