 Uncloud covers all the essentials for operating apps in production without overwhelming you with the complexity of
 traditional container orchestrators like Kubernetes or Swarm:
 
+* Initial machine and network setup
 * Zero-downtime rolling deployments
 * Health checks and automatic restarts
 * Automatic HTTPS and reverse proxy configuration
 * Scaling services across multiple machines
-* Cross-machine service communication
