Cloud Architecture

Own hardware first. Cloud where it makes sense.

Multi-cloud deployment architecture for the xsubi ecosystem — bare metal, edge, and cloud providers working as one mesh.

Architecture Philosophy

Control the core. Extend to the edge. Cloud is a deployment target, not a dependency.

Deployment Topology

roboNet drones form a unified mesh across all deployment targets

Cloud Providers

In Production

Cloudflare

Current Usage

  • DNS management for xsubi.com
  • Cloudflare Tunnel to learning.xsubi.com
  • CDN and DDoS (Distributed Denial of Service) protection
  • Email forwarding
  • Subdomain management
  • DDNS (Dynamic DNS) for dynamic IP

Planned

  • Workers for edge compute (roboNet relay)
  • Tunnel-based drone mesh bridge
  • R2 for artifact storage
Free Tier 100K Workers requests/day, 10GB R2
Planned — Q2 2026

Oracle Cloud Infrastructure (OCI)

Deployment Plan

  • ARM A1.Flex instance (roboNet edge drone)
  • Swarm member connecting to bare metal queen
  • Network recon from cloud vantage point
  • Cross-provider mesh validation

Why OCI

  • Most generous always-free tier
  • 4 OCPU ARM + 24GB RAM (free forever)
  • 200GB block storage included
  • 10TB/month outbound data
Always Free ARM A1.Flex — no expiration, no credit card charges
Planned — Q2 2026

Google Cloud Platform (GCP)

Deployment Plan

  • e2-micro instance (roboNet edge drone)
  • Lightweight mesh participant
  • Geographic diversity for latency testing
  • Cloud Functions for event-driven relay

Why GCP

  • e2-micro always free (us-west1, us-central1, us-east1)
  • 30GB HDD persistent disk
  • 1GB Cloud Storage
  • Strong tooling (gcloud CLI)
Always Free e2-micro — 0.25 vCPU, 1GB RAM, no expiration

Bare Metal Foundation

The core infrastructure runs on owned hardware — cloud extends, never replaces

In Production

xsubi Data Center

Infrastructure

  • Ubuntu Linux — KVM/libvirt hypervisor
  • Windows Server 2022 DC — Hyper-V
  • Kubernetes cluster (platform services)
  • PostgreSQL 16 (xmark, Grafana)
  • Prometheus + Grafana monitoring
  • Loki + Promtail log aggregation

Services

  • VM provisioning (KVM + Hyper-V)
  • Game server hosting
  • roboNet queen (swarm hub)
  • Jenkins CI/CD pipeline
  • Docker container registry
  • Redis session store

Cloud Deployment Roadmap

Q1 2026
Bare Metal + Cloudflare Foundation
Own hardware operational. Cloudflare DNS, tunnels, and CDN protecting all xsubi services. roboNet queen running on bare metal.
Completed
Q2 2026
Multi-Cloud Edge Deployment
Deploy roboNet edge drones to Oracle Cloud ARM and Google Cloud e2-micro. Validate cross-provider mesh connectivity and heartbeat reliability.
In Progress
Q3 2026
Cloudflare Workers Relay
Edge compute relay nodes on Cloudflare Workers. Sub-50ms message routing through the CDN edge network. Tunnel-bridged mesh between cloud providers.
Planned
Q4 2026
Federation + Cross-Cloud Recon
Multi-hive federation across providers. Network recon from each cloud vantage point. Unified monitoring through Prometheus federation.
Planned
