Infinito.Nexus Architecture Overview

Introduction

Infinito.Nexus (Cyber Master Infrastructure Solution) is a modular, open-source IT infrastructure automation platform designed to simplify the deployment, management, and security of self-hosted environments.

It provides a flexible, scalable, and secure architecture based on modern DevOps principles, leveraging technologies like Ansible, Docker, and Infrastructure as Code (IaC).

An additional optional security layer allows full server encryption during installation using LUKS based on this solution:

Key Points

  • Modular role-based architecture

  • Infrastructure-as-Code (IaC)

  • Docker-based containerization

  • Centralized Identity & Access Management (IAM)

  • Security by Design

  • Integration instead of forced migration

  • Optional full disk encryption layer for servers

Architecture Layers

1. Automation Layer

  • Ansible Playbooks & Roles

  • Git-managed configuration repository

  • Inventory-driven infrastructure definition

2. Container Orchestration Layer

  • Docker Compose service deployment

  • Per-role service templates

  • Automated health checks & updates

3. Security & Identity Layer

  • Centralized user management via LDAP

  • Single Sign-On (SSO) with Keycloak

  • Secrets management via Ansible Vault

4. Networking Layer

  • Secure VPN via WireGuard & OpenVPN

  • Nginx Reverse Proxy with automated TLS via Let’s Encrypt
