We are currently using Opendaylight for our IoT solution at OASIS Digital (a water utility).
The support we have received is excellent - they really were very helpful when I was having some problems with it initially setting up my cluster of nodes within an Azure VM farm; their engineers quickly resolved this problem which made me feel more confident to continue working through other issues as well! It's still early days but so far everything looks good about ODL/opENNs integration into Microsoft Biztalk Server 2016 or even Apache Kafka where appropriate depending what your requirements might be? Again though there doesn't appear any major drawbacks yet either regarding how easy things seem simple enough that anyone can set them-up themselves given suitable knowledge / experience etc.. There does not need too much technical expertise required if you're already comfortable administering servers then yes definitely go ahead otherwise ensure someone else will assist along side yourself until such time comes :).
