Expert perspectives on AWS cloud consulting, generative AI, and enterprise solutions.
July 2026 field note: Aurora failover windows still force app timeouts above tens of seconds; DynamoDB hot partitions and short transactions remain the scaling levers — with a partition-math worksheet you can reproduce.
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.
July 2026: API Gateway REST integrations still default to a 29s timeout (quota increases possible for Regional/private); WebSockets bill per message and connection minute — bake both into SLOs 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 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.
July 2026: nine migration mistakes that still show up after Migration Hub closed to new customers on November 7, 2025 — Application Migration Service (MGN), DMS, AWS Transform, Org/SCPs, FinOps dual-run costs, and Migration Lens.
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).
July 2026 Terraform command reference for AWS — Terraform 1.10+ plan/apply/state, use_lockfile, import/removed/ephemeral, and the five Monday-morning checks that close real failure modes.
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.
