Delve into advanced Kubernetes features like monitoring, alerting, logging, and auto-scaling. Gain insights into creating resilient, self-adaptive clusters and applications with minimal manual intervention.

The world of DevOps has exploded with the help of technologies like Kubernetes and Docker.  
In this course, you will learn about more advanced Kubernetes features such as monitoring, alerting, logging, and scaling - crucial concepts for any DevOps professional. You will learn how to monitor clusters, how to send alerts when potential issues arise, and how to query the whole system’s metrics and logs. 
By the end of this course, you will have the required knowledge to make your clusters and applications truly dynamic and resilient, so that they require minimal manual involvement and are self-adaptive.

Advanced Kubernetes Techniques: Monitoring, Logging, Auto-Scaling

Our goal is to deploy an application that will be automatically scaled (or de-scaled) depending on its use of resources. We'll start by deploying an app first, and discuss how to accomplish auto-scaling later.



In this lesson, we will first deploy an app and see how to change the number of replicas based on memory, CPU, or other metrics through `HorizontalPodAutoScaler` resource.
