Digest #203: AWS 100K Credits, Scaling GitOps, Git inside Postgres and OpenClaw Security

Reducing Go agent binaries by 77% and saving 70% on S3 at petabyte scale, to automating RDS to Aurora migrations and scaling GitOps in the enterprise. Also, MCP server security and scaling GitOps.

Welcome to this week’s edition of the DevOps Bulletin.

Big news this week includes an exclusive offer for DevOps Bulletin subscribers: up to $100k in free credits for building or scaling your stack on AWS. Our curated stories share how Datadog reduced its Go agent binaries by 77%, Netflix’s journey migrating RDS Postgres workloads to Aurora, enterprise strategies for scaling GitOps, rendering 100 million pixels per second over SSH, FinOps tips to reduce 70% of S3 cost, running Git inside Postgres, and why securing OpenClaw may be the wrong problem to solve.

Tutorials this week go deep into Postgres fundamentals, Docker BuildKit, and hard lessons from real-world SQL queries, as well as building Terraform review agents with Gemini, designing secure agent skills and MCP servers, and deploying a production-ready, scalable code modernization platform.

The open source picks include an autonomous Claude powered multi agent system that turns Linear issues into reviewed pull requests, a PostgreSQL proxy with connection pooling and sharding, a terminal dashboard for managing cron jobs over SSH, a VSCode extension that visualizes SQL lineage and dependencies, a local first AI agent task manager, and an S3 native Kafka compatible event streaming server built as a single Rust binary.

All this and more in this week’s DevOps Bulletin, don’t miss out!
