Abstract: Embodiments described herein are generally directed to techniques for avoiding or mitigating shared-state damage during a split-brain condition in a distributed network of compute nodes. According to an example, a number, N, of nodes within the distributed computing system is determined. During normal operation of the distributed computing system, a unified state is maintained by synchronizing shared state information. The nodes are ordered by increasing importance to an application from 1 to N. A quora value, qn, is assigned to each of the nodes in accordance with the ordering, where q1=1 and each subsequent quora value, qn+1, is a sum of all prior quora values, q1 to qn, plus either 1 or a current value of n. These quora values may then be used to determine membership in the dominant or a yielding set to facilitate recovery from the split-brain condition by performing pessimistic or optimistic mitigation actions.

Abstract: Examples described herein relate to securing communication between a cloud platform and applications running on an on-premise private network of a tenant. The cloud platform includes a communication delegate mapped to a tenant of the cloud platform. The communication delegate may receive data traffic associated with the tenant and directed to an application hosted on an on-premise private network. The communication delegate may encrypt the data traffic to generate an encrypted data traffic using a unique certificate associated with the communication delegate and communicate the encrypted data traffic to the application via a secure communication tunnel specific to the tenant between the communication delegate and the on-premise private network.
