The virtual machines themselves kept running fine, but nobody could reach them, and there was a risk that some machines might lose the ability to save data properly. This indicates that even managed cloud infrastructure can experience failures in critical shared network components,” said Pareekh Jain, CEO at EIIRTrend & Pareekh Consulting.
Neil Shah, vice president at Counterpoint Research, said the real culprit here is the SDN orchestration control plane, where a routine internal network update or configuration tweak introduced routing failure across multiple zones. “While most of the physical nodes are distributed for exactly this redundancy purpose, they are still tightly coupled to a singular shared orchestration fabric, so if that control plane crashes, then everything comes crashing down, and the physical distributed nodes become irrelevant.”
Stretched clusters fall short
Although the outage did not bring down virtual machines, the incident undermined the primary reason enterprises deploy stretched clusters.
