We are in the process of finding a system integrator (SI) to implement a new integration platform as a service solution (iPass) (we are still deciding between Dell Boomi or Mulesoft) and I wanted to ask my peers if you have any advice on the SI's you have partnered for iPass implementation?

Have you looked at Digital Integration Hub on Gartner research? It’s a good option to implement end-to-end integration solutions that leverage Data Fabric, Microservices and APIs to build a modular solution

Dell Bhoomi, is an amazing solution integration platform, it is a very matured product that has been around for more than a decade with impeccable success stories. We have used it in one of our 3PL logistics and shipping business vertical wherein we had more than 20 sources of data from various customers' systems and in house applications. The integration was seamless without little or no deviations and failures. However, we need to have a good implementation partner and I would suggest to engage with Dell Bhoomi itself for the professional service, despite the ticket price being relatively high it is worth it given the quality of work and the end to end hand holding.
