Self-healing networks of Infrastructure Processing Units (IPUs) and associated methods and apparatus. The self-healing IPUs manage other processing units (XPU) clusters by seamlessly migrating the IPU responsibilities to another IPU in the networked environment (e.g., data center) that may be available when an IPU failures or becomes unavailable. A central Resource Manager is used to monitors the health of the IPUs in the data center and in the event of in IPU failure, locates another IPU and assigns it to take over the failed IPU's functions. Replacement and workload migration of a failed XPU in an IPU managed XPU cluster with a remote XPU that is network connected is also supported. The IPU monitors the health of the XPUs in its cluster an informs the Resource Manager of an XPU failure which locates another XPU in the data center and assigns it to the cluster that has the failed XPU.
