Autoscaling Kubernetes Pods and Nodes

Needless to say, having autoscaling capabilities for your cloud-native application is considered the holy grail of running applications in the cloud. In short, by autoscaling, we mean a method of automatically and dynamically adjusting the amount of computational resources, such as CPU and RAM, available to your application. The goal of autoscaling is to add or remove resources based on the activity and demand of end users. So, for example, an application might require more CPU and RAM during daytime hours, when users are most active, but much less during the night. Similarly, for example, if you are supporting an e-commerce business infrastructure, you can expect a huge spike in demand during so-called Black Friday. In this way, you can not only provide a better, highly available service to users but also reduce your cost of goods sold (COGS) for the business. The fewer resources you consume in the cloud, the less you pay, and the business can...
