Day 17/40 - Kubernetes Autoscaling Explained| HPA Vs VPA

Welcome to day 17/40 of the Certified Kubernetes Administrator course. In this video, we will demonstrate Kubernetes Autoscaling and explore VPA, HPA, Cluster Autoscaler, and Node AutoProvisioning in Kubernetes.

In this video, you'll learn:
- What is scaling in Kubernetes
- Horizontal vs Vertical Scaling
- HPA vs VPA
- Cluster autoscaling vs. Node auto-provisioning
- Demo Implementing HPA by simulating load on the cluster

👨🏼‍💻 #40daysofKubernetes Challenge:

📖 Course Schedule:
I'll release 3-4 videos per week and host live Q&A sessions on weekends to answer your questions and guide you through the CKA certification process.

🕵🏻‍♂️ Who Should Watch:
This CKA course is designed for beginners, college students, and working professionals who want to learn Kubernetes from scratch, prepare for the CKA certification exam, or enhance their knowledge. It was designed based on the latest curriculum for the CKA exam in May 2024 and uses 1.30.2 as the Kubernetes version.

Let's start your Kubernetes journey together!

Your teaching style is amazing—thank you!

[CloudEnthusiastic]

Cmon Piyush Sir.... we are all with you...such a great content...I am not even thinking to take break while watching your video.... you are explaining in such a way that the person will be hypnotized.

[eapenmani]

Clearly articulate the autoscaling in K8s. Thank you

[nitinsaini]

Amazing content, following this series and gaining deep knowledge. Thanks for this sir 🙂

[nithinprabhakar]

Great explanation. Now tis concept is also clear!!

[subhralahari]

Thank you for such wonderful effort for your explanation on HPA and VPA

[sangativamsikrishna]

Thanks piyush for the explaining the HPA concept along with horizontal and vertical scaling concepts.

[mike]

Thank you so much for your explanation on HPA and VPA

[guntreddirajesh]

Great explanation, kudos to you Piyush, keep helping the community.we are here to support you

[AyanKhan-zhit]

I was really confused by hearing these concepts of k8s, services, autoscaling, resources, taint, tolerations, node affinity, etc. But after watching your videos, it feels like all these concepts are really easy, we just need to give some time and understand everything by practicing them along with the lectures.
Thank you for the amazing lectures Piyush!
I request you to explain the cluster autoscaler and Node Auto provisioning in some future videos

[somenghosh]

Very well put up .. once again rich content by Piyush

[radhikaGudidesi]

I always thought K8s was difficult to learn, but it is easy after watching your videos.

[MayurLokhande-ln]

echo "Very nicely and cleanly explained"
echo " Thank You sir"

[lokeshkassey]

Can we use HPA and VPA at a time (interview question) few internet references are saying yes, few no

[artbart]

Hello.As usual great explanation!
However i had an error running the load generator:
Error:
pod "load-generator" deleted
pod default/load-generator terminated (StartError)
failed to create containerd task: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: exec: "C:/Program Files/Git/usr/bin/sh": stat C:/Program Files/Git/usr/bin/sh: no such file or directory: unknown
I'm on Windows machine.
In my case this worked :

[vamsikrishna]

is this CKA course is relevant for role Devops engineer?

[sagarbirla]

Hi Piyush, number of Replicas are not going down even after the CPU Utilization is 0 and it's been 30 minutes

[vivekgautam]

what is the use of hpa.yaml ?
you only used deploy.yaml
