AWS Blueprint — LABP-Stack

Production-ready cloud architecture for VoIP, AI and Automation platforms. Designed for scalability, security and operational resilience.

This blueprint represents the reference infrastructure used across LABP-Stack deployments and consulting projects.

Status: MVP + Production Ready
Scope: Contact Centers, Voice Platforms, AI Gateways
Cloud: AWS-Oriented Architecture

Core Components

Amazon VPC with segmented subnets (Public / Private)
EC2 instances (Asterisk, Media Gateways, AI Services)
Application / Network Load Balancer
RDS / DynamoDB for metadata and control data
S3 for call recordings and artifacts
CloudWatch for metrics, logs and alerts

High-Level Architecture

Users (Voice / Web / API)
        ↓
AWS Load Balancer (ALB / NLB)
        ↓
API Layer (Railway / AWS / Containers)
        ↓
VoIP Core (Asterisk / SBC / AI)
        ↓
Automation & Storage (n8n / S3 / DB)

This layered design enables independent scaling of voice, AI and automation components while maintaining operational stability.

MVP Deployment Model

Single VPC
2–3 EC2 instances
Basic ALB / NLB
S3 lifecycle policies
CloudWatch basic monitoring

Target: Proof of concept, pilot projects, controlled production.

Production Deployment Model

Multi-AZ architecture
Auto Scaling Groups
Redundant SIP trunks
Multi-region backup
Disaster Recovery Plan (DRP)
Centralized logging

Target: High-volume contact centers, carrier-grade platforms, mission-critical systems.

Security Architecture

TLS / SRTP encryption
IAM Roles with least privilege
Network isolation via Security Groups
WAF for API protection
Geo-blocking and fraud detection
Encrypted storage (S3 / RDS)

Operations & Observability

Structured application logging
CloudWatch dashboards
Automated alerting
Backup automation
Capacity monitoring

Designed for 24x7 operations and proactive incident management.

Integration with LABP-Stack
