Techniques are disclosed for efficiently updating multiple computing systems in potentially heterogeneous computing environments. Embodiments provide for efficient patching of multiple software applications executing in multiple execution environments. For example, a custom installation tool can be provided to each of the computing devices in the cloud infrastructure system. The computing devices can execute the custom installation tool and identify, retrieve, and apply the necessary patches to applications on the computing devices. The patch-related processing across the multiple computing devices may occur in parallel such that at least a portion of the processing is performed concurrently from one another.
