Autoscaling in Kubernetes

In the deployments chapter of this series, we've seen how to scale our deployments manually. That way, whenever there is unusual traffic, we can scale our deployment accordingly. But, monitoring our traffic continuously and manually scaling our application to handle such traffic spikes is tedious.
What if there is a way to monitor our pods and scale them automatically whenever there is an increase in CPU usage, memory, or some other metric like QPS? This is called autoscaling(scaling automatically based on some metrics). Kubernetes can do that job for us. Not only pods, if we're running on cloud infrastructure, K8s can also spin up additional nodes if the existing nodes can't accept any more pods. In this chapter, we'll learn how different auto-scalers (Horizontal Pod Autoscaler, Vertical Pod Autoscaler, Cluster Autoscaler) work with complete hands-on.

SIr, If Cluster Auto Scaling searching un schedule pods automatically new vm will create . But if un schedule pods are present with other reasons.

why didn't you explain about the target and uncapped target in VPA, I am specially looking for it only. Can anyone explain me in well about all 4 parts of recommendation in case of VPA

@rsrini7 2 ай бұрын

So the HPA target is compared with deployment request right ? limit is optional so it wont compare ?

I deployed my database, mongodb, with replicaset. I have 3 replicas. i use headless service the name is "mongo". i know that i only can R/W in the PREMARY database and only /R from the SECONDARY database . connection string is like this "mongodb://mongo-0.mongo,mongo-1.mongo,mongo-2.mongo:27017" i dont know if this coonection string act like load lancer or i need to have two connection string . 1-"mongodb://mongo-0.mongo:27017" to write in database , PREMARTY 2- "mongodb://mongo:27017" to read data from data base , a load lancer

u r telling i think wrong in increse pods means scale out u r telling the scale up and derese means scale down i think

@PavanElthepu Жыл бұрын

Hmm! With you. Scale up is generally used to increase resources, and scale-out means adding more pods. However, Scale up and Scale out are used interchangeably generally. Here is the reference from K8s official documentation: "This means that the HPA is still capable of scaling up if one or more metrics give a desiredReplicas greater than the current value."
