Deep dives into AWS architecture, serverless patterns, and cloud-native development. Learn from production-grade engineering.
Logs default to Never Expire, retention only cuts storage and not ingestion, the charge stops before deletion does, and every dimension combination is a separate billable metric.
The under-5% Spot figure is a cross-region historical average, the default allocation strategy is one AWS labels not recommended, and the EKS Auto Mode fee survives every discount.
An idle API Gateway cache invisible to request graphs, Lambda startup billed but not logged, and why savings figures cannot simply be added together. Including one my own scanner gets wrong.
CloudFront plans that bill while disabled, IPv4 addresses that stopped being free, gateway endpoints that never took over, and cross-AZ transfer that names no service.
Database Savings Plans have a Generation 7 floor, Redshift has no Savings Plan at all, ElastiCache coverage is Valkey-only, and GPU Capacity Blocks rose 38%.
Bucket Keys cover new uploads only, and a lifecycle configuration written before September 2024 changes behaviour the moment anyone edits an unrelated rule.
The July 2026 billing estimate bug, why off-hours scheduling saves less than the arithmetic promises, and what support priced as a percentage of spend really costs.
EKS, RDS MySQL 5.7 and MySQL 8.0 all crossed into extended support pricing in 2026. Every one defaults to on, Reserved Instances do not cover it, and only two actions stop it.
A deep dive into building scalable IoT platforms with AWS IoT Core, Kinesis, and Lambda, including patterns for real-time alerting and time-series analytics.
Step-by-step guide to building Retrieval-Augmented Generation systems using AWS Bedrock, FAISS, and LangChain for production-ready AI applications.
