Digest #204: AWS Data Centers Hit, Kubernetes Full Course, LLM Caching and AI Pentesting

AWS data centers struck by drones in UAE, 2,863 Google API keys exposed to Gemini, LLM caching architectures, Terraform feature flags, and AI pentesting tools.

Welcome to this week’s edition of the DevOps Bulletin.

From Iranian drone strikes taking down AWS data centers in the UAE and Bahrain, to Truffle Security finding 2,863 live Google API keys on the public internet that now silently authenticate to Gemini.

On the tutorial side, we get into designing caching architectures that cut LLM costs by 30% through semantic deduplication, building AI agents for infrastructure teams with proper safety guardrails, and a hands-on guide to pg_semantic_cache in Postgres that achieves 60-80% cache hit rates. Plus: debugging Go memory leaks with pprof, secure error-handling patterns in Go, and AWS cost optimization with up to 72% savings.

This week’s open-source picks include Shannon - an autonomous AI pentesting framework that validates vulnerabilities using real exploits, Titus - a high-performance secrets scanner with 487 detection rules, and safe-chain — a local proxy that blocks malicious npm and PyPI packages before installation.
