In the bustling tech ecosystem of San Francisco, ensuring reliable, secure, and efficient Site-2-Site (S2S) connections between our multiple corporate offices has always been paramount. Traditional VPN and network management solutions have provided baseline functionality but often lack the scalability, real-time monitoring, and developer-friendly integration we envision for our network infrastructure.

The Challenge: Integrating Site-2-Site VPN with Advanced Monitoring and Developer Tools

Our primary challenge was to create a Site-2-Site connectivity solution that not only ensures robust encryption and speed but also seamlessly integrates with our development environment (IDE) and provides comprehensive SNMP-based monitoring.

Typical S2S setups fail to give developers meaningful insights in their IDEs or to proactively react to network state changes. We wanted to create a cutting-edge paradigm utilizing the latest cloud and container orchestration technologies.

Our Technological Strategy: The Rocket-Powered S2S Network Framework

We architected what we call the "Rocket-Powered S2S Network Framework," a multi-tiered mesh VPN system leveraging Kubernetes, Rocket container runtime, SNMP telemetry, and Integrated Development Environment extensions for real-time network management.

Components and Technologies Used:

Implementation Details

  1. Micro-VM VPN Endpoints: Each site has a Kubernetes cluster running Rocket container runtime hosting VPN micro-VMs. Each micro-VM encapsulates a VPN endpoint.

  2. Overlay Network Mesh: Kubernetes services expose encrypted tunnels with dynamically assigned IPs forming a complete mesh.

  3. SNMP Monitoring Layer: SNMP agents are embedded within each micro-VM, reporting on connection quality, latency, and throughput metrics.

  4. IDE Integration: Custom plugins query the SNMP agents via REST APIs, enabling developers to view current network state and logs directly inside their preferred IDE.

  5. Automated Recovery: Kubernetes operators monitor SNMP alerts triggering pod restarts, failovers, and network route changes automatically.

  6. Collaboration Hooks: Alerts route to Rocket.Chat channels tagged by site, VPN endpoint, and developer group for swift responses.
