What is the term for tailored software that connects different systems or services?

The term that refers to tailored software designed to connect different systems or services is custom integration. This approach involves creating specific applications or scripts that allow disparate systems or services to communicate and function together seamlessly. Custom integration often addresses unique business requirements or workflows that off-the-shelf solutions cannot effectively handle. It enables organizations to enhance interoperability among varied platforms, improving productivity and facilitating data sharing.

When discussing this concept, it's important to note that while terms like system interfacing and application middleware also relate to connectivity between systems, custom integration specifically emphasizes the tailored aspect of the solution, ensuring it meets the unique needs of the organization. Service binding generally refers to the act of connecting services in a more abstract manner, often within service-oriented architectures, but lacks the specific focus on tailored solutions that custom integration offers.
