Insights & Resources

CloudWatch Logs Insights bills $0.005 per GB scanned and high-cardinality custom metrics multiply costs. Cardinality budgets, sampling rules, and FinOps fixes.

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.

Nine recurring program mistakes still show up in 2026 reviews—especially after AWS closed Migration Hub to new customers on November 7, 2025. Practical fixes tied to AMS (MGN), DMS, AWS Transform, Org/SCPs, FinOps bubble costs, and the Migration Lens checklist.

On May 6, 2026, AWS made its managed MCP server generally available in 2 regions—with IAM guardrails, CloudWatch metrics, and CloudTrail logging—while the March 25, 2026 Agent Plugin for AWS Serverless brought packaged SAM/CDK skills into Cursor and Claude Code.

A curated, production-tested guide to microservices patterns on AWS — what to use, what to skip, and what changed in 2026 (App Mesh EOL, VPC Lattice, Powertools idempotency, Step Functions sagas).

Every Terraform command you actually need on AWS — modernized for Terraform 1.10+, with deprecated commands flagged and AWS-specific gotchas for state, workspaces, providers, and the new import/removed/ephemeral primitives.

AWS just made OpenAI's frontier models, Codex, and production-ready Managed Agents available inside Amazon Bedrock — wrapped in IAM, PrivateLink, Guardrails, and CloudTrail. Here is what changes for CTOs evaluating OpenAI direct vs. AWS.

Most teams buy Bedrock Provisioned Throughput too early or too late. This is the break-even math — by token volume, by model family, and by traffic shape — that we use in real FinOps engagements to decide which Bedrock pricing mode wins.

AWS Lambda can now mount S3 buckets as a POSIX file system. At roughly $0.023 per GB-month for large files it is about 13× cheaper than EFS — but a 60-second write-back delay, broken advisory locks, and atomic-rename quirks will break naive ports. Here is when to use it, when to wait, and how to wire it up safely.

Anton Babenko's Terraform Claude Skill is the biggest jump in AI-assisted IaC since Copilot. We tested it on a real AWS stack — VPC, EKS, S3 + KMS, IAM — and documented exactly what it fixes, what it misses, and what AWS teams should layer on top.

Bedrock Automated Reasoning checks ground LLM outputs against formal logic policies you encode and mathematically validate that the response is consistent with the policy. This guide covers when to use Automated Reasoning vs contextual grounding, how to author the policy in production, the integration with Bedrock Guardrails, and the regulated use cases (HR, insurance, eligibility, regulatory determinations) where the difference matters.

CloudTrail Event History on the default plan isn't your audit trail — it's a 90-day story you tell auditors. A production CloudTrail setup with multi-region trails, KMS encryption, log file integrity validation, and CloudTrail Lake as the queryable layer for incident response and compliance evidence.
