REST job submission instead of SSH in data pipeline

Transitioning from SSH to REST-based job submission changes the behavior of the data pipeline at the architectural level. This is about manageability, fault tolerance, and resource control. The problem does not manifest immediately — until the system hits a scale limit. In this case, over 700 jobs were executed via SSH to EMR clusters. This … Read more

WebRTC routing reduces latency in voice AI

WebRTC routing is becoming critical for voice AI, where audio stream continuity and minimal latency are essential. We analyze how the reworking of routing changes system behavior under load. The problem does not manifest immediately — until the moment the system scales to global real-time traffic. In the classic WebRTC model of “one port per … Read more

HSM vault for E2E backup without trust in the platform

HSM backup vault enhances end-to-end encryption for backups. The architecture eliminates platform access to keys and introduces verifiable trust. The problem arises when backups leave the device and enter the cloud. Even with end-to-end encryption, the question remains: who controls the recovery keys and how can it be proven that the provider does not have … Read more
