What Is Scaling In Kubernetes?
Scaling in Kubernetes simply means adjustment (dynamically), adjustment of the number of running models of an application or service based on the requirement/need. In Kubernetes with the help of scaling, we can easily manage our resources, and make sure they are consistently available and capable of handling variable requirements. In simple words, I would say it is the process of dynamically adjusting available resources.
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.
