Welcome to this week's Uptime Sync. This issue opens with Intercom's battle-tested playbook for upgrading Elasticsearch with zero downtime using dual-write strategies and snapshot restoration, an honest take from Charity Majors on why generative AI won't build your engineering team for you despite the hype, a clear mental model for thinking about Kubernetes that cuts through the complexity, practical guidance on choosing the right multi-agent architecture when building with LLMs, and the surprising story of how Tailwind CSS announced 75% layoffs as AI reshapes open-source business models.
On the tutorial front, you'll build centralized alerting across AWS organizations using CloudWatch, EventBridge, Lambda and CDK, monitor your Docker homelab setup with Coroot for full observability, harden Kubernetes security by integrating DevSecOps practices into your workflow, build a production-ready RAG system for just $5/month (while alternatives cost $100-200), optimize SQL indexes in PostgreSQL and MySQL for query performance, and master the prompt-chaining framework for writing effective LLM prompts that actually work.
To wrap things up, this week's projects bring you zrok for securely sharing web services and files through firewalls using zero-trust networking, CopilotKit for deploying deeply-integrated AI assistants inside your applications, undb as a no-code platform that doubles as a Backend-as-a-Service, autojump for intelligently navigating directories from the command line, and Memos: an open-source, self-hosted note-taking service with no tracking, no ads, and full data ownership.
