Welcome to this week’s Uptime Sync. This issue covers a 500 GB production MariaDB migration from Amazon RDS to EC2 with a rollback path, GitHub’s September availability report, and Docker Hub’s security advisory. We also look at how one team systematically improved reliability, Envoy Gateway’s load-testing results, and lessons from a VMware migration using Proxmox and Terraform.
On the tutorial front: a closer look at cron, zero-downtime Postgres upgrades with logical replication, and ways to avoid AWS NAT Gateway costs. We also cover reducing storage initialization impact after an RDS PostgreSQL snapshot restore, removing excessive permissions from Kubernetes service accounts, and why running the same Postgres query twice can return different results.
This week’s projects bring you httptap for tracing HTTP requests through DNS, connection setup, TLS, wait time, and transfer; Cozystack for a free Kubernetes-based cloud platform; AI Job Search for running a Claude Code-based job application workflow on your machine; and Agent Containers for running command-line coding agents in restricted Docker images.
