Enterprise E-commerce Platform

Project Overview

A production-grade, highly scalable e-commerce platform built entirely on Kubernetes with a microservices architecture. This project showcases enterprise-level DevOps practices including GitOps deployment, automated CI/CD pipelines, comprehensive observability, and zero-downtime deployments.

The platform handles high-traffic loads with auto-scaling capabilities, implements service mesh for secure inter-service communication, and maintains 99.9% uptime through robust infrastructure automation and disaster recovery procedures.

Platform Engineering & Infrastructure

DevOps & Infrastructure Stack

Production-grade DevOps implementation with enterprise best practices:

• Container Orchestration: Kubernetes 1.28+ / OpenShift 4.x with multi-zone deployment
• GitOps: ArgoCD for declarative continuous deployment and configuration management
• CI/CD: GitLab CI with multi-stage pipelines, automated testing, and security scanning
• Service Mesh: Istio for traffic management, security, and observability
• Container Registry: Red Hat Quay / JFrog Artifactory for secure image storage and scanning
• Secrets Management: HashiCorp Vault for secure credential storage and rotation
• Monitoring: Prometheus + Grafana with custom dashboards and alerting
• Logging: EFK Stack (Elasticsearch, Fluentd, Kibana) for centralized log aggregation
• Tracing: Jaeger for distributed tracing across microservices
• API Gateway: Kong / NGINX Ingress Controller with rate limiting and authentication
• Message Queue: Apache Kafka for event-driven architecture and async communication
• Caching: Redis cluster for session management and application caching
• Database: PostgreSQL with Patroni for HA, MongoDB for product catalog
• Backup & DR: Velero for cluster backup and disaster recovery
• Security: Falco for runtime security, Trivy for vulnerability scanning

CI/CD Pipeline Architecture

Comprehensive automated pipeline from code commit to production:

• Source Control: GitLab with branch protection and merge request workflows
• Build Stage: Multi-stage Docker builds with layer caching for optimization
• Test Stage: Unit tests, integration tests, and contract testing
• Security Scan: SAST (SonarQube), DAST, dependency scanning, and container scanning
• Image Build: Buildah/Kaniko for rootless container builds in Kubernetes
• Image Scan: Trivy and Clair for vulnerability detection in container images
• Registry Push: Signed and scanned images pushed to Quay with RBAC
• GitOps Sync: ArgoCD automatically deploys to staging environment
• Smoke Tests: Automated smoke tests run against staging
• Production Deploy: Blue-green or canary deployment with manual approval gate
• Health Checks: Automated health verification post-deployment
• Rollback: Automated rollback on failure detection

Observability & Monitoring

Comprehensive observability stack for production monitoring:

• Metrics: Prometheus for metrics collection with 100+ custom metrics
• Dashboards: Grafana with 20+ dashboards for infrastructure, application, and business metrics
• Alerting: AlertManager with PagerDuty integration for critical alerts
• Logs: Centralized logging with EFK stack, 30-day retention, and advanced search
• Tracing: Jaeger for end-to-end request tracing across all microservices
• APM: Application performance monitoring with custom instrumentation
• Uptime Monitoring: External monitoring with status page
• Cost Monitoring: Kubecost for resource utilization and cost optimization

High Availability & Disaster Recovery

Enterprise-grade HA and DR implementation:

• Multi-Zone Deployment: Services distributed across 3 availability zones
• Database HA: PostgreSQL with Patroni for automatic failover
• Redis HA: Redis Sentinel for cache high availability
• Kafka HA: Multi-broker Kafka cluster with replication factor 3
• Backup Strategy: Velero for daily cluster backups, database PITR
• DR Testing: Quarterly disaster recovery drills with documented runbooks
• RTO/RPO: Recovery Time Objective < 1 hour, Recovery Point Objective < 15 minutes
