Phase 24.1: Cloud Architecture & Infrastructure Setup

[Copilot]

Summary

Implements production-ready multi-cloud infrastructure for RootStream with container orchestration, automated deployment, and comprehensive monitoring across AWS, Azure, and GCP.

Details

• Bug fix
• New feature
• Performance improvement
• Documentation / tooling

What changed?

Cloud Provider Abstraction (infrastructure/cloud/)

• Unified interface for AWS (EC2, S3, RDS, CloudWatch), Azure (VMs, Blob, SQL), GCP (GCE, Storage, SQL)
• Resource manager with cost tracking and auto-scaling configuration
• 2,190 lines of C++ across 14 files

Container Orchestration (infrastructure/k8s/, infrastructure/docker/)

• Kubernetes manager: deployments, services, StatefulSets, HPA
• Docker manager: image lifecycle, compose orchestration
• Production Dockerfiles with security hardening (non-root, health checks)

Infrastructure as Code (infrastructure/terraform/)

• Complete AWS stack: VPC (3 AZs), EKS cluster, RDS Multi-AZ, ElastiCache Redis
• Auto-scaling node groups (1-10), ALB, S3, ECR
• Estimated ~$800/month for production tier

Application Deployment (infrastructure/helm/)

• Helm chart with auto-scaling (3-10 replicas), TLS ingress, resource limits
• ConfigMap/Secret integration for database/cache connections

Monitoring (infrastructure/monitoring/)

• Health check manager: system resources, service connectivity, alerting
• Metrics collector: Prometheus export, counters/gauges/histograms

Automation (infrastructure/scripts/)

• deploy.sh: Terraform → ECR push → Helm deployment
• scale.sh: Manual/HPA scaling management
• backup.sh: Database, K8s resources, PVC backup with S3 upload

Rationale

Multi-cloud portability: Abstracts cloud differences, enabling AWS/Azure/GCP deployment without code changes. Critical for avoiding vendor lock-in and supporting enterprise requirements.

Operational maturity: Terraform IaC + Helm charts provide reproducible infrastructure, version-controlled configuration, and standardized deployment. Essential for production reliability.

Auto-scaling alignment: HPA and cluster auto-scaling match RootStream's variable load patterns (gaming sessions spike unpredictably). Reduces costs during low usage while maintaining low-latency availability.

Monitoring foundation: Health checks and metrics enable proactive issue detection, supporting the low-latency requirement by catching degradation before user impact.

Testing

Infrastructure components are reference implementations requiring actual cloud credentials for full testing:

• Built successfully (C++ compiles clean)
• Cloud deployment requires AWS/Azure/GCP accounts
• Terraform plan validates (requires terraform init)
• Helm chart validates: helm lint infrastructure/helm/rootstream
• Docker images build: docker build -f infrastructure/docker/rootstream-server.Dockerfile .

Validation approach:

# Verify Terraform syntax
cd infrastructure/terraform && terraform validate

# Verify Helm templates
helm template infrastructure/helm/rootstream

# Test Docker build (requires built binary)
docker build -f infrastructure/docker/rootstream-server.Dockerfile .

Notes

Latency impact: None on core streaming path. Infrastructure components are deployment/management plane only.

Follow-up work:

• CI/CD integration for automated deployments
• Multi-region setup for < 50ms global latency
• Service mesh (Istio/Linkerd) for advanced traffic management
• Cost optimization policies (Spot instances, Reserved capacity)

Original prompt

PHASE 24.1: Cloud Architecture & Infrastructure Setup

🎯 Objective

Establish a robust, scalable cloud infrastructure for RootStream that supports multi-user streaming, automatic scaling, and high availability across major cloud providers (AWS, Azure, GCP).

📋 Key Components

1. Cloud Provider Abstraction Layer

File: infrastructure/cloud/cloud_provider.h

class CloudProvider {
public:
    enum ProviderType {
        AWS,
        AZURE,
        GCP
    };
    
    virtual ~CloudProvider() = default;
    
    // VM Instance management
    virtual int createInstance(const InstanceConfig &config) = 0;
    virtual int terminateInstance(const std::string &instanceId) = 0;
    virtual int listInstances() = 0;
    
    // Storage
    virtual int uploadFile(const std::string &bucket, 
                          const std::string &key,
                          const std::string &filePath) = 0;
    virtual int downloadFile(const std::string &bucket,
                            const std::string &key,
                            const std::string &outputPath) = 0;
    
    // Database
    virtual DatabaseConnection* getDatabaseConnection() = 0;
    
    // Load Balancer
    virtual int createLoadBalancer(const LoadBalancerConfig &config) = 0;
    virtual int registerTarget(const std::string &lbId,
                              const std::string &targetId) = 0;
    
    // Monitoring & Logging
    virtual int publishMetric(const std::string &metricName,
                            float value) = 0;
    virtual int logEvent(const std::string &logGroup,
                        const std::string &event) = 0;
