● INSIGHTS
Cloud / AWS in practice
Cloud optimization is not a search for cheaper instances. Teams control cost and reliability together only when billing mechanics, permissions, networking, delivery, and operational ownership share one design.
● RECOMMENDED READING
From billing mechanics to security-driven spend
Begin with hidden AWS costs to learn how line items grow, then use the LLMjacking case to trace how a security incident becomes operational spend. Continue structural application change in the separate modernization hub.
What should an AI gateway control? Enterprise requirements and implementation pathsCloud / AWS in practice · July 29, 2026A practical framework for putting security, key exposure, departmental cost, guardrails, and observability behind one enterprise AI gateway, with four implementation paths compared.→
How MCP 2026-07-28 changes AgentCore operationsCloud / AWS in practice · July 27, 2026How MCP's request-oriented model changes deployment and state ownership across AgentCore Runtime, Gateway, and targets, with a practical dual-version migration path.→
Why we added Blacksmith to GitHub Actions: 1,527 jobs, performance, and costCloud / AWS in practice · July 23, 2026Why 801 PLANET runs GitHub Actions jobs on Blacksmith, using six months of data from 1,527 jobs, 1,487 Docker builds, and actual invoices. We also map when AWS CodeBuild is the better fit.→
An AWS Account With No Keys and No Docs — How $1,650/mo Became $400Cloud / AWS in practice · July 20, 2026We re-read a six-year-old service's abandoned AWS account through API inventory and measured metrics, then executed an Aurora major upgrade and rightsizing with zero-downtime tooling. Monthly cost dropped to a quarter without touching application code.→
A $455K AWS Cost Alert Arrived — The Response Made It WorseCloud / AWS in practice · July 19, 2026An AWS alert put one day of S3 data transfer at $455,000. The estimate was wrong, but we still had to investigate account compromise. The incident shows why billing communication is part of cloud security.→
Invisible on the Console, Only on the Invoice — AWS's Hidden CostsCloud / AWS in practice · July 10, 2026Nobody broke in, yet money leaks every month. Missing VPC endpoints, cross-AZ data transfer, always-billed public IPv4, logs kept forever. AWS hidden costs with real Seoul-region rates and how to claw them back.→
Anatomy of an AWS Bill Shock — LLMjacking, and the Costs You Never SeeCloud / AWS in practice · July 9, 2026One leaked access key can burn tens of thousands of dollars a day on Bedrock. How LLMjacking works, the AWS account-management essentials, Bedrock key management, and the guardrails that cap the blast radius.→
● COMMON QUESTIONS
Common cloud cost and security questions
Why can an AWS bill rise when compute usage looks stable?+
Data transfer, NAT, logs, snapshots, and managed-service calls can grow outside the compute line. Compare service-level usage and unit changes before treating the total as one number.
Should cost optimization start with Savings Plans?+
Remove idle capacity, oversizing, excessive retention, and inefficient network paths first. Evaluate commitments after the usage baseline becomes stable enough to avoid locking in waste.
Why is LLMjacking both a security and a cost incident?+
Stolen credentials can invoke expensive models and resources, turning unauthorized access directly into usage growth. Permission scope, anomaly detection, and cost alerts belong in one response system.
