Sda

SDA (software defined architecture)

Physical Infrastructure

Proxmox Server Specifications

The foundation of the architecture is a physical server running Proxmox VE hypervisor.

Component	Description
Hypervisor	Proxmox Virtual Environment (VE)
Virtual Machines	Multiple Talos OS nodes forming a Kubernetes cluster
Containers	LXC container serving as a router

Virtual Machine Configuration

# Example Talos configuration structure (simplified)
machine:
  type: controlplane  # or worker
  network:
    hostname: talos-node-1
  kubernetes:
    version: v1.26.0

Networking Architecture

Network Components

Component	Function
Proxmox Virtual Bridge	Creates isolated network segments for VMs and containers
LXC Router	Routes traffic between internal and external networks
Kubernetes Overlay Network	Enables pod-to-pod communication (Cilium, Flannel, etc.)

Control & Automation

API Management Layer

This architecture leverages multiple declarative APIs for infrastructure management:

API	Responsibility
Proxmox API	Manages physical resources, VMs, and containers
Talos API	Provides declarative OS configuration and maintenance
Kubernetes API	Orchestrates applications and services

Benefits of This Architecture

Immutable Infrastructure: Talos OS provides an immutable, declarative operating system
High Availability: Kubernetes manages service availability and distribution
Resource Efficiency: Consolidates multiple services on a single physical server
Isolation: Separate network segments and container boundaries
Automation: API-driven management at all levels
