Sir, I finally got a job as a DevOps engineer even though I had a one-year gap and didn't have any certifications. After all this, I got a job with a better package than some experienced engineer colleagues. The company is product-based, and I built a resume in one hour, then got the interview and received the offer letter on the same day. This was something I did not expect; my life changed in 2-3 days. I was so hopeless. Thank you, sir, for your videos, and I'm still learning from them every day.
Some video tutorials takes days in conceptualising and execution and this is one such tutorial. However, all that effort is worth if you(subscribers) find the video informative. Service Mesh and Istio is a complex topic. Hope I simplified it for you all. Do let me know 😊
Thanks for uploading this video and for your efforts in making this video , Is the video related to Kubernetes troubleshooting series or else it's different
Yes, True @Abhishek, I saw many tutorials but this was simple and easy to digest ServiceMesh and Istio concept.😅 Thanks once again for your continous series...
Never came across a tutorial so engaging and so well explained for anyone to understand the concept clearly and you kept it Simple which reaches everyone, when you get the basics right you get it everything! you nailed it Abhishek, thanks
@@AbhishekVeeramalla and I can say that all your efforts have been fruitful to everyone and I wish this video becomes available to anyone who wants to learn in right way
Hi Abhishek, I just wanted to take a moment to express my gratitude for the incredible work you're doing on your TH-cam channel. Your ability to break down complex topics like service mesh into simple, easy-to-understand explanations is truly impressive. Your videos have been an invaluable resource for me, making the learning process much smoother and more enjoyable. Thank you for your dedication and for sharing your knowledge so generously. Keep up the fantastic work!
these concepts are everywhere, if anyone wants they can go for official documentation too. but the confidence fills up only after you explaining them Abhishek. Thanks !!
Papa telling you the truth, i was telling my mate few days back that I will be studying Istio mesh soon.. And today your video popped up😅... I was thinking about kubernetes trouble shooting again your videos popped up... You are reading our minds Annaa... ❤❤❤❤
@@AbhishekVeeramalla the best part is you look like vijay sethupati as well, that's why people are liking you more slim version of sethupati... Today I looked at you closely annaa you are similar to him calm 😌 nd sweet 🍬🍭
I'm delighted to have stumbled upon this video. The explanations provided are excellent and incredibly valuable. Thank you for all the effort you put in.
Abhi i love watching your videos and performing the demos.. Your series in k8s and that of Mumshad also motivated me to becoming a CKA,CKAD and CKS certified.. If you have time pls Demo Autoscaling in k8s using KEDA with prometheus and aws sqs as trigger, your way of teaching is unique.
if I remember correct then Microservices was introduced to better utilize the existing systems/infra & reduce the cost but it has caused more cost, requiring more infra where most tasks will be done to maintain that bloated infra. means it has caused a whole new ecosystem around.
Hi Abhishek... Appreciate for teaching these concepts.. One request from my side.... Need detailed view on Cloud Service Mesh concepts... I'll be waiting for this video...
Super Work. Its very best explnation like kodekloud istio course(PAID one). kindly upload AKS service mesh(Istio) setup and configuration . your video is always handy for learners.

Hi Anna, since week im looking for Istio related stuff but i didn't get complete understanding. I hope this video will answer all my questions. Thanks.

@AbhishekVeeramalla I am confident that this video is among the best. Despite its challenging content, it effectively addresses all my doubts. Additionally, I kindly request a practical video covering all deployment strategies-a topic frequently asked about in all interviews.” 🎥🚀
Hi, great video! After applying the sidecar injector with Istio, I'm encountering the 426 Upgrade Required issue. Could you provide any guidance on how to resolve this problem or where I might be going wrong in the configuration?
Hey Abhishek, if the resources are limit for namespace. How istio create sidecar container ?after app pod creation? Does this use the same resources available in the namespace .
Hi Abhishek, Never heard of admission controllers. But this explanation makes sense now how our client requests actual validated at control plane. I have a quick doubt..? What happens if one of admission controller is not present and i make a contradictive request. Example: in the example you showed on requestQuota, assume requestQuota admission controller is not enabled. What happens when you deploy pod which requires more cpu than actual resource quota of the namespace..! ?
Another master piece thank you Abhishek. Is there any plan to have some videos on Airflow? or its not in the scope of DevOps? Once again thank you for this.
Woww thank you Abhishek bro for doing it am really waiting for this content, also we are looking for service mesh on high level and how to use it . also can you please do some videos on Helm charts and to convert our deployment files to helm charts
Kiali is mainly focusing on the traffic management, but I need a lit bit more information about my cluster. So, I have tried an open source APM tool called Apache SkyWalking. It is giving a detailed info about our clusters, but I'm unable to configure apache skywalking with istio. If possible can you make a video on this ?......So that many of the people will also know about this open-source APM tool. Thanks in advance😄

Hi bro, in realtime perspective, we will have multiple nodes in our organizations right, so while implementing istio, using that "istio-injection-enabled" we can restrict the implementation of Istio to the particular namespace level only right?? it doesn't have apply across all the cluster wide ? correct me if iam wrong!!
Hi Abhishek, Thanks again for the wonderful video it’s highly knowledgeable, could you please suggest if we can use in our environment service mesh with ingress resource, ingress controller? Also request to make a video on Hashicorp vault how the secrets injects in kubernetes pods with every possible combination like static secrets kv enginee injection to k8s, dynamic secrets injection vis agents to k8s as per your way 🙏
@@AbhishekVeeramalla There is no kube-apiserver pod for eks or doks. Even when you check for pods running in the kube-system namespace. You only find network plugins, storage csi, kube-proxy and not the main k8s master nodes components.

hey, I got the same error. It might be due to the resourcequota we applied earlier to limit the CPU and memory usage. We did that to check the validation admission controller. To resolve this, run - 'kubectl delete resourcequota quota-demo' Verify if the quota limit is removed - 'kubectl get resourcequota' Now the pods will be up and running. If still any issues, just try restarting the deployments - 'kubectl rollout restart deployment '

Hey Abhishek, if the resources are limit for namespace. How istio create sidecar container ?after app pod creation? Does this use the same resources available in the namespace .
should we also use istio to manage redis kafka traffic or just install redis and kafka outside istio?
Thank you so much
You're most welcome
Hi Abhishek as the trafiic management is done using Envoy so is there an issue with the latency going forward? Thanks
Amazing question brother. Yes, that is one of the main drawbacks when istio is setup for large clusters.

What happens if one of admission controller is not present and i make a contradictive request.

in realtime perspective, we will have multiple nodes in our organizations right,
so while implementing istio,
using that "istio-injection-enabled" we can restrict the implementation of Istio to the particular namespace level only right??
it doesn't have apply across all the cluster wide ?

Bro please do a video for sending logs from kubernetes to S3 using any tool
Guys, Can i get any recommend channels for DevOps ideas & real time project
Hey, there are 40+ real time projects on the channel. Check the real time projects playlist
Sir service mesh done explain API GATEWAY also
