IBN has helped us with our hybrid IT infrastructure by migrating several services onto Azure including both On Premise as well as Office 365 Services (SharePoint).
Their team of experts are very knowledgeable so they can assist you right away when problems arise or questions come up during implementation phase. Nothing that comes into mind at this time but if there was anything then it would be their follow through once project completion date came around for each service migration/deployments were done successfully without any issues experienced afterwards.
