Maintain Pipelines
Introduction
In this lesson, we explore how to maintain and optimize CI/CD pipelines in Azure DevOps. This guide covers essential concepts and strategies to ensure your pipelines remain healthy, efficient, and secure.
Monitoring Pipeline Health
Understanding pipeline health is critical for a smooth CI/CD process. In this section, we cover a range of topics related to health monitoring, including:
- An overview of pipeline health monitoring and its significance.
- Identification and analysis of key performance metrics.
- A review of the analytics tools available in Azure DevOps.
- Techniques for handling flaky tests, along with strategies and tools to minimize test instability.
- How Azure Test Plans can enhance your CI/CD process.
- Best practices for dependency and security scanning to maintain robust pipeline health.
Note
Regular monitoring of your pipeline's health allows early detection of issues and deviations, ensuring a reliable CI/CD workflow.
Optimizing Pipeline Concurrency
Efficient management of pipeline concurrency is key to balancing performance and cost in Azure Pipelines. This section delves into:
- An introduction to pipeline concurrency and its role in CI/CD.
- The core benefits of effectively managing concurrency in your pipelines.
- Practical strategies and best practices for optimizing concurrency.
- How to improve performance while effectively controlling costs through proper concurrency handling.
Key Information
Balancing concurrency is essential for scaling efficiently. Overloading pipelines can lead to performance bottlenecks and increased costs.
Migrating from Classic Pipelines to YAML
Migrating from Classic Pipelines to YAML is a transformative step for modernizing your CI/CD process in Azure Pipelines. In this section, you will learn:
- An introduction to pipeline migration and the benefits of using YAML.
