Secure Multi-Tenant Monitoring Platform on Kubernetes

Design and Implementation of a Secure Multi-Tenant Monitoring Solution Using Kubernetes, Grafana, Prometheus, Zabbix, and Azure DevOps

This project focuses on designing and deploying a secure, scalable, and multi‑tenant monitoring platform based on Kubernetes. The goal is to provide a centralized, cloud‑ready solution capable of monitoring infrastructure, applications, and network activity while ensuring strong authentication, automation, and continuous delivery.

Key Objectives

• Deploy a complete monitoring stack using Grafana, Prometheus, and Zabbix on a Kubernetes cluster installed with kubeadm.
• Implement secure authentication using SAML (Entra ID) for Grafana and LDAP/Active Directory for Zabbix and Azure DevOps.
• Ensure storage resilience through NFS‑based shared storage.
• Automate CI/CD pipelines using Azure DevOps Server to build, test, and deploy monitoring components.
• Integrate Trivy to scan Helm charts and Docker images for vulnerabilities.
• Provide a multi‑tenant architecture, enabling separate environments for different organizational units.

Architecture Highlights

• Kubernetes cluster deployed on‑premise with kubeadm.
• Grafana exposed via HTTPS with self‑signed certificates, secured by SAML (Entra ID).
• Prometheus for metrics collection and alerting.
• Zabbix deployed through Helm with LDAP authentication.
• Azure DevOps Pipelines used for automated deployments and configuration updates.
• NGINX Ingress Controller with TLS termination.
• NFS server for persistent and centralized storage.

DevOps & Security Features

• Automated CI/CD pipelines for monitoring updates.
• Infrastructure‑as‑Code using Helm and YAML manifests.
• Security scanning using Trivy (images + Helm charts).
• Authentication hardening (LDAP + SAML).
• Role‑based access management for multi‑tenant environments.

Deliverables

• A fully functional end‑to‑end monitoring platform.
• Comprehensive documentation including architecture diagrams, deployment procedures, and security guidelines.
• Demonstration of monitoring dashboards, alerts, logs, and integration with enterprise identity providers.

Impact

The project delivers a robust, enterprise‑grade monitoring ecosystem suitable for large organizations. It enhances visibility, improves security, and reduces operational overhead by leveraging automation and modern orchestration tools.
