Introduction

Cloud-native applications, designed to be highly scalable and flexible, require effective monitoring to ensure performance, reliability, and quick troubleshooting. Prometheus, a powerful open-source monitoring and alerting toolkit, is widely used for monitoring cloud-native environments due to its robust capabilities for time-series data collection and analysis. This course will guide you through leveraging Prometheus for cloud-native application monitoring, focusing on scalable insights and optimal performance.

Prerequisites

• Basic understanding of cloud-native architecture and containers
• Familiarity with Kubernetes, Docker, and microservices
• Experience with monitoring systems and basic metrics concepts
• Familiarity with Prometheus basics (optional but helpful)
