Glad it was helpful!

Means a lot 🙏🏻

Glad you liked it!

Yes, working on it.

Sure, will announce a dedicated series on this.

Appreciate your support 🙏🏻🙏🏻

Thanks, Hariom.

There are already two courses on my channel 1) Python interview questions for DevOps ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-4fecE98pUL0.html 2) Python for Beginners ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-CFVJOvBbJfg.html

@@LogicOpsLab thank you but is it sufficient for fresher who want to switch in devops .

@@mayurmadan7956 Indeed. For Python, yes!

Welcome!

On the context of "how does kubernetes helps with microservice architecture." The answer can be multifold, it depends how a person is explaining it. Here's how Kubernetes helps with microservice architecture: Containerization: Kubernetes is built around containers, which are an ideal packaging format for microservices. Containers package the application and its dependencies into a single unit, making it easy to deploy and manage microservices independently. Scaling: Kubernetes enables automatic scaling of microservices. You can define scaling rules and policies for individual microservices based on factors like CPU utilization, memory usage, or custom metrics. This ensures that your microservices can handle varying workloads efficiently. Service Discovery and Load Balancing: Kubernetes provides built-in service discovery and load balancing. Microservices can communicate with each other using service names, and Kubernetes takes care of routing traffic to the appropriate instances. This simplifies communication between microservices. Resource Isolation: Kubernetes enforces resource isolation and resource quotas. Each microservice can be allocated specific CPU and memory resources, ensuring that one service does not adversely affect others. Now, this is not the complete list, there can be several other aspects, as well..

Can you please help me with the timestamp?

@@LogicOpsLab FB question came on 20:40 but m not able to track for federated cluster

Could be possible, people are getting smarter these days.

Here's a simplified overview of the recovery process: Detection: When the master node becomes unavailable, whether due to a crash or other reasons, the Kubernetes nodes and other components in the cluster will detect the loss of connectivity to the control plane. Failover: Kubernetes has a mechanism called "leader election" that allows other nodes to elect a new master from the available nodes. This process is often managed by tools like kube-controller-manager and kube-scheduler. A new master node will be elected, and control plane services will be rescheduled on this new master. Etcd Recovery: The etcd cluster may also need to recover if the etcd nodes on the failed master were part of the etcd cluster. Etcd is designed for high availability and can handle failures, but the recovery process may take some time. If the etcd cluster suffered a quorum loss (e.g., losing the majority of its nodes), you may need to intervene manually to restore the quorum. Cluster Stability: Once a new master is elected and etcd is stable again, the Kubernetes cluster will regain its stability, and you can resume managing and deploying applications in the cluster. It's important to note that the specific steps and configurations for recovery may vary depending on your Kubernetes setup, including the choice of networking, cloud provider, and other infrastructure components.

Good question.

Ha ha. I also felt he was simply telling anything. Many places he wasnt even clear

Agree 💯 , even I feel more knowledgeable without CKA certification😅😅 , the way he's answering I am afraid 😅

Don't worry, you aren't losing out on much. He is not answering properly, plus most of his answers did not make sense.

@@LogicOpsLab yes, could you please make videos on the same interview which will answer properly for us

@@sabapathan8018 Yes, started a separate series for the same.

@@LogicOpsLab > plus most of his answers did not make sense. I understand his English was not very clear, but his answers were satisfactory. I found that he had knowledge of everything that you asked..it's just that he couldn't frame his answers properly.

@@neerajkumar81 The stakes were high for this position.

Hi, Kiran. Please comment down the correct answers as feedback. This will help other folks, as well.

True. He was rejected, and wasn't able to clear the interview.

@@LogicOpsLab can you please guide me, I am 1 years of exp. and have hands on exp on aws eks with both node as a service and fargate as a service (serverless), api gateway,lambda ,R53 and various Aws services, have done linux configurations inside ec2 and have self learned on docker and k8s and know a bit of shell scripting also , I want to switch from this job because i am not getting challenging work and brainstorming projects

Trained hirer here. Have you ever heard about proxy certifications? In order to find out if the candidate is real or not we always start with basic ones and then increase the difficulty level. I think he's doing just fine. Also, he had put 32 videos here before some dumbass girl threatened his job. This used to be one stop solution for junior to mid senior level interviews. Gone are the days. 😢😢

Thanks for the feedback.

Thanks for the feedback

What do you think?

At a few places, yes.

Please switch on the subtitles
