In-depth technical articles on AWS architecture, serverless, security, cost optimization, and cloud engineering best practices.
The official aws/agent-toolkit-for-aws repo ships 43 atomic Agent Skills across 13 category folders—plus aws-core, aws-agents, and aws-data-analytics plugins. Here is why that bundle matters for IAM and audit posture, how the tree fits together, and how to pair it with the May 6, 2026 GA AWS MCP Server.
GitHub Actions OIDC role sessions are short-lived by design—teams still paste static access keys into workflow logs until scanners or audits catch the diff; supply-chain writeups keep repeating the pattern into 2026.
Aurora storage replication is cross-AZ by design; writer failover targets typically complete in tens of seconds—plan application timeouts above that window or you ship self-inflicted outage amplification every failover drill.
Standard SQS queues sustain nearly unlimited throughput per queue (AWS-documented pattern) while FIFO caps at 300 TPS per API batch without high-throughput mode—your May 2026 architecture review should start from those numbers, not from Kafka slogans.
API Gateway REST APIs cap integration timeouts at 29 seconds; WebSocket APIs bill per message and connection minutes—your May 2026 API design should bake those numbers into SLO tables before picking protocols.
As of May 8, 2026, Lambda bills INIT time on cold paths (pricing change live since Aug 1, 2025), API Gateway REST integrations time out at 29 seconds, and picking ALB vs NLB still determines whether TLS termination and routing live on the edge.
CloudWatch Logs Insights charges about $0.005 per GB scanned (US East pricing, May 2026)—a “cheap query” run every minute across full indexes becomes a five-figure monthly line item faster than most teams model.
API Gateway REST integrations still max out at 29 seconds—if your Lambda keeps retrying a 35-second partner HTTP call without a bounded circuit, you burn capacity and duplicate side effects instead of failing fast.
