LLMOps Architecture

Architecture Diagram Figure – LLMOps Architecture Diagram

The MLAngles LLMOps platform employs a multi-region AWS cloud architecture designed for high availability, scalability, and security. Below is a detailed explanation of each component and their interactions within the platform topology.

Core Infrastructure Components​

Traffic Management & DNS

  • Route 53: Manages DNS routing and provides intelligent traffic distribution between regions, ensuring optimal latency and failover capabilities
  • Internet Gateway: Enables bidirectional communication between VPC resources and the internet

Load Balancing & Auto-Scaling

  • Application Load Balancers (ALB): Distribute incoming traffic across multiple instances in both regions, providing health checks and SSL termination
  • Auto Scaling Groups: Automatically adjust the number of Frontend and Backend instances based on demand, ensuring consistent performance during traffic spikes

Application Layer​

Frontend Services

  • Deployed across multiple availability zones with auto-scaling enabled
  • Serves the web interface and user-facing components
  • Distributed across public subnets for direct user access

Backend Services

  • Handles API requests, model inference, and data processing
  • Deployed in both public and private subnets for security segregation
  • Integrated with auto-scaling groups for dynamic resource allocation

Application Modules (1, 2, 3)

  • Represent different microservices or functional components of the LLMOps platform
  • Each module can scale independently based on specific workload requirements

Data & Storage Layer​

RDS (Relational Database Service)

  • Provides managed database services for persistent data storage
  • Configured for multi-AZ deployment ensuring high availability
  • Positioned in private subnets for enhanced security

Security & Compliance Services​

  • IAM Role: Manages access permissions and service-to-service authentication
  • AWS WAF: Web Application Firewall protecting against common web exploits
  • KMS (Key Management Service): Handles encryption keys for data at rest and in transit
  • Secrets Manager: Securely stores and rotates database credentials and API keys
  • VPC: Provides network isolation and security boundaries for all resources

Monitoring & Operations​

  • CloudWatch: Centralized monitoring for metrics, logs, and alarms across all services
  • SNS (Simple Notification Service): Sends alerts and notifications for system events
  • S3 Backup: Automated backup storage for disaster recovery and data retention

Network Architecture​

Multi-Region Design

  • Two identical regions configured for active-active or active-passive failover
  • Ensures business continuity and reduced latency for geographically distributed users

Subnet Strategy

  • Public Subnets: Host internet-facing resources like load balancers and NAT gateways
  • Private Subnets: Contain backend services and databases, accessible only through internal routing

Gateway Configuration

  • Internet Gateway: Provides internet connectivity for public resources
  • Internal Gateway: Manages communication between VPCs and private resources

This architecture ensures the MLAngles LLMOps platform delivers reliable, secure, and scalable LLM operations with built-in redundancy and comprehensive monitoring capabilities.
