Rolling Updates: Ensuring Zero Downtime

Overview

Kubernetes, provides flexibility and control over application deployments, enabling seamless scaling and updates without downtime. Understanding how to effectively scale applications and manage rolling updates can significantly enhance application’s performance and stability.

Scaling Applications in Kubernetes

Scaling involves adjusting the number of replicas — instances of a particular application pod — running in a cluster. Scaling can be performed manually or automatically, based on specific metrics like CPU usage or memory consumption.

Manual Scaling

Manual scaling is achieved by using the kubectl scale command. For example, increasing or decreasing the number of replicas for a deployment ensures that the application can handle varying loads efficiently.
