Guide to Kubernetes Scaling: Horizontal, Vertical & Cluster
Blog post from Spacelift
Kubernetes is a container orchestration system designed to simplify the process of deploying and managing containerized apps, offering support for scalability and high availability. It can be scaled at either the workload or cluster level through horizontal scaling (adding extra instances) and vertical scaling (resizing existing resources). Key auto-scaling mechanisms include Horizontal Pod Autoscaler (HPA), Vertical Pod Autoscaler (VPA), and Cluster Autoscaler. To ensure predictable and reliable scaling, it's important to use appropriate resource requests and limits, assign workloads to the most suitable Node type, utilize Pod Disruption Budgets, and maintain a correct rollout strategy for each Deployment.
