☸️ 5. Kubernetes

Best for: Container orchestration at scale.

Kubernetes (K8s) is an open-source platform for automating deployment, scaling, and management of containerized applications.

Key Features:

• Auto-scaling

• Self-healing services

• Helm charts for templating

💡 Pro tip: Use managed services like GKE, EKS, or AKS to simplify setup.

🛠 6. Sentry

Best for: Real-time error monitoring and debugging.

Sentry helps developers monitor and fix crashes in real time. It integrates with many programming languages and frameworks.

Key Features:

• Error tracking

• Performance monitoring

• GitHub/Slack integrations

✅ Free plan available for small teams and side projects.

📊 7. Prometheus + Grafana

Best for: Metrics collection and observability dashboards.

Prometheus scrapes time-series metrics and Grafana visualizes them beautifully. Together, they form the backbone of many DevOps monitoring stacks.

Key Features:

• Alerting and querying with PromQL

• Pre-built Grafana dashboards

• Flexible integrations (Kubernetes, Node Exporter, etc.)

📌 Use case: Monitoring infrastructure, applications, and custom services.
