Anti-Design Pattern Series - Why Deployment Metrics Matter in Kubernetes - Blog #14

Updated: Apr 12, 2023






Introduction:


Metrics play a crucial role in detecting and predicting incidents in Kubernetes deployments. While logs and tracing are helpful for post-incident analysis, metrics enable real-time incident detection and capacity adjustments. In this blog post, we'll discuss why metrics are essential in Kubernetes deployments and how automation can help incorporate metrics into the deployment process.

Kubernetes deployments are highly distributed, making metrics more important than ever before. With ephemeral applications, understanding how they respond to changes in traffic volume is critical. By quickly obtaining vital information, you can pinpoint bottlenecks and adjust resource capacity for optimal performance.



However, the most crucial use case for metrics is knowing whether or not your deployment was successful. Just because a container is online doesn't mean the application is running or accepting requests. Incorporating metrics into every step of the deployment process is crucial, and automation is key.



Automated rollbacks and rollouts can be triggered based on metric analysis, and the deployment can be designated as complete or reverted after comparison to a baseline. Human intervention is not required in these processes, making metrics an invaluable tool for efficient and effective Kubernetes deployments.



In conclusion, metrics are not something you should look at once in a while. They should be incorporated into every step of your deployment process to ensure optimal performance and incident detection.
