Types of Scaling in Kubernetes
There are primarily two types of scaling,
- Horizontal scaling/Horizontal Pod Autoscaler (HPA): This feature can effortlessly add or release pod replicas automatically.
- Vertical scaling/Vertical Pod Autoscaler (VPA): This feature in which CPU and memory reservations adjust automatically.
- Cluster Autoscaler: In this feature an analysis of resources occurs, and we make essential adjustments in the deployment and handle the load.
Kubernetes Horizontal vs Vertical scaling
In Kubernetes, scaling is the most fundamental concept that makes sure applications run smoothly and consistently. Just consider a scenario where low resources are causing the application to freeze under the existing load. One potential solution is to manually assign the resources whenever this occurs, but it will take a lot of time. This is the place where scaling(moreover autoscaling) comes into action: the ability to scale applications to meet varying needs efficiently is one of the key features of Kubernetes.
