How We Handle Deploys Without Downtime

Here’s how we ship new versions of our platform without interrupting your services.

If you’re like us, you’ve probably deployed something late at night hoping nothing breaks.

At Improved Connections, we designed our deployment process to be boring — in the best way. Every update goes through a zero-downtime process, built for both static and full stack apps.

🔄 Our Deployment Process

  1. Build: Code is built in an isolated container.
  2. Pre-flight check: Health checks run on the new version before routing traffic.
  3. Blue-green switch: Once verified, traffic is routed to the new version instantly.
  4. Rollback plan: If anything fails, we roll back to the previous stable version in seconds.

Here’s what a minimal deploy script might look like:

#!/bin/bash

echo "Building new version..."
docker build -t app:latest .

echo "Running health checks..."
./scripts/healthcheck.sh || exit 1

echo "Routing traffic to new version..."
kubectl set image deployment/app app=app:latest

echo "Done."
