WizFi Microservices 🚀

---

🔑 Highlights

• ✅ 8+ Microservices (Frontend, Auth, User, Admin, Billing, Payments, Analytics, Notifications)
• ✅ Kubernetes (k3s) orchestration with NGINX Ingress
• ✅ End-to-End SSL/TLS via Let’s Encrypt + cert-manager
• ✅ PostgreSQL with Persistent Volumes for data durability
• ✅ Monitoring & Alerting stack (Prometheus, Grafana, Alertmanager → Slack)
• ✅ Infrastructure as Code with Terraform on AWS EC2
• ✅ Helm-based deployment for modular rollouts & upgrades
• ✅ CI/CD pipelines with GitHub Actions

📌 This is a portfolio-grade project that demonstrates real-world DevOps engineering and cloud-native practices end-to-end.

🚀 Setup & Deployment

1️⃣ Infrastructure (Terraform on AWS EC2)

cd terraform
terraform init
terraform apply

2️⃣ Cluster Setup (K3s)

curl -sfL https://get.k3s.io | sh -

3️⃣ Deploy Microservices

kubectl apply -f k8s/

4️⃣ Helm Deployment

cd wizfi-microservices-helm
helm install wizfi ./ --namespace wizfi

5️⃣ Ingress + SSL/TLS

kubectl apply -f manifests/ingress.yaml

Access via: https://wizfiservices.duckdns.org

⚡ CI/CD Workflow (GitHub Actions)

-Build & Push Docker Images → GitHub Container Registry

-Deploy to K3s via kubeconfig secret

-Auto-SSL Renewal via cert-manager

-Automated Testing with curl-based health checks

📊 Monitoring & Observability

-Grafana Dashboards for cluster + microservices

-Prometheus Alerts → Slack notifications

-Node Exporter + Kube State Metrics for system health

🚀 Future Improvements

-🔒 Service Mesh with Istio or Linkerd

-🌍 Multi-node HA setup

-📦 Canary Deployments & Progressive Delivery

-☸️ Kubernetes Operator for automation

-📈 Advanced SLO/SLI tracking
