Root cause analysis as code in SRE systems

Root cause analysis (RCA) hinges on scale and the human factor. Meta’s approach with DrP demonstrates how to turn debugging into a reproducible engineering process. The problem does not manifest immediately — until the system reaches organizational scale. Incidents begin to recur, but each time they are investigated anew. Knowledge of where to look for … Read more

Platform Program split at Uber under growth pressure

Platform Program split became a key step for Uber when the growth of the team began to hinder development. This decision changed both the architecture and the organization simultaneously. The problem manifested not at the code level, but at the level of team interaction. When Uber’s engineering organization grew to about 100 people, the division … Read more

Kubernetes Gateway API instead of Ingress NGINX

Migration from Ingress NGINX is becoming mandatory: EOL and vulnerabilities make the transition to Kubernetes Gateway API a matter of resilience and security. The problem does not manifest immediately — until control over incoming traffic becomes a point of systemic risk. Ingress NGINX has long been the de facto standard for Kubernetes, but its lifecycle … Read more

Symbolic execution for BPF malware analysis

Symbolic execution simplifies the analysis of BPF malware and eliminates a bottleneck in reverse engineering. This approach allows for the automatic reconstruction of “magic” packets to trigger backdoors. The problem does not manifest immediately — until the analysis of BPF malware encounters the complexity of the filters themselves. The classic Berkeley Packet Filter operates as … Read more
