AI Infrastructure

Kubernetes is no longer just a container orchestrator — it is the production operating system for AI. According to the CNCF Annual Cloud Native Survey (January 2026), 82% of container users now run Kubernetes in production, and 66% of organizations hosting generative AI models use Kubernetes to manage some or all of their inference workloads. For network engineers, this convergence of cloud-native infrastructure and AI workloads represents the most significant architectural shift since the move from hardware-defined to software-defined networking. ...

Microsoft’s MOSAIC technology replaces traditional laser-based optical cables with MicroLED-powered interconnects that cut data center networking power consumption by up to 68%. Announced in March 2026, MOSAIC uses hundreds of parallel low-speed channels on medical-grade imaging fiber to deliver 800 Gbps throughput over 50 meters — ten times the reach of copper — while consuming only 3.1–5.3W per link compared to 9.8–12W for conventional optics. With a working proof-of-concept transceiver built in collaboration with MediaTek, Microsoft targets commercialization by late 2027. ...

AWS Bedrock AgentCore Code Interpreter allows attackers to exfiltrate sensitive data using DNS queries even when running in “Sandbox” mode — and AWS says this is intended behavior, not a vulnerability. Security researchers from Phantom Labs and Sonrai Security have independently demonstrated that DNS resolution capabilities bypass sandbox isolation, enabling credential theft, S3 bucket enumeration, and full command-and-control channels through a protocol that every firewall permits by default. Key Takeaway: If your organization deploys AI agents with code execution capabilities in AWS, the word “sandbox” does not mean what you think it means — DNS-based exfiltration works regardless of network mode, and overpermissioned IAM roles turn a DNS covert channel into a full data breach. ...
