Course Description

Kubernetes is a container orchestration technology - a way to create and deploy clusters of machines running containers, usually Docker containers.
Kubernetes is also one of the hottest topics in tech today, because it is perhaps the only straightforward way to architect a hybrid, multi-cloud compute solution.
Let's parse that:
Hybrid: This is a solution where an enterprise has a private cloud or on-premise data center, in addition to using one of the public cloud providers (such as AWS, GCP or Azure). Any firm migrating to the cloud is going to have to run a hybrid setup, at least during the migrationMulti-cloud:
This refers to the use of more than 1 cloud provider. Why is this so important? Well, because most large firms are unwilling to be completely locked into one provider, particularly after events like Amazon's acquisition of Whole Foods (that gave pause to a whole lot of potential AWScustomers, who decided that 'multi-cloud' makes sense for strategic reasons)Only straightforward way:
Most cloud providers offer a range of compute solutions, ranging from PaaS (Elastic Beanstalk, or Google AppEngine) to IaaS (EC2, or Google Compute Engine VMs). The reality is that PaaS ties you down to 1 cloud provider, and IaaS is a lot of hassle, during migration and beyond.
Kubernetes is supported by each of the Big-3: GCP has a special relationship with Kubernetes (since K8S originated at Google) but now AWS and Azure support it as well. Kubernetes has won the battle of the container orchestration systems.
This is why containers running on Kubernetes constitute the hottest compute choice for a hybrid, multi-cloud world.
Here is now is what this course contains:
Docker, Kubernetes and the cloud platforms: understanding the inter-relationshipsPods and containers: Pods are the basic building block in K8S; each pod holds one or more containers that are tightly-coupled to each otherReplicaSets: Higher-level abstractions that provide scaling and auto-healing (they encapsulate pods, and bring new podsback up if the old onescrash)Deployments:
Even higher-level abstractions that provide versioning, fast rollback, rolling updates and moreServices:
Front-end abstractions (think of them as similar to load-balancers) that are loosely coupled with backend pods. Services provide a static, stable network frontend IP, as well as load-balancingOther K8S objects: StatefulSets, Secrets, ConfigMaps, Jobs and CronJobs and moreCKAtest tips: We don't reveal any information about the test that we should not, such as specific questions. But we do discuss the test format, what to expect, pitfalls to avoid,and strategies for successHope you enjoy the course!
Who this course is for:
Cloud Architects looking to understand the compute choices on AWS, Azure and GCPTechnical decision makers evaluating a hybrid, multi-cloud solutionDevops professionals looking to master KubernetesAnyone seeking to take and pass the CNCF Certified Kubernetes Administrator test

needs to be updated to reflect common issues found in current GKE environment. Namely the resource-limited-pod.yaml fails to run in the setup.

By Joe McCormick on 11/14/2020

I enjoyed the course but wish it was more up-to-date.

By Yogesh BS on 11/7/2020

Sample yaml files could have been provided to download and use
If there any config required it could have been done

By Peter Ware on 10/20/2020

The class and examples were very useful for my needs. It was a very thorough introduction and did not assume pre-knowledge. I like that you explained why things were done. A couple of times when exercising the examples I hit CPU resource issues or setup issues that were not covered in how to get around these issues.

By Mohan Bethur on 9/27/2020

Overall good training. Labs are good.
But lot of repetition which can be avoided.
Like that "disk space" required on Google to install curl can get irritating.

By Sajith Sathiadevan on 9/25/2020

Course is little outdated but caters to the concepts well. It would be better if the course is updated with sections on Persistent Storage and PVCs

By Li Wang on 9/24/2020

He does not know how to talk.............

By Raj Lalsangi on 9/23/2020

A good, fast paced introduction. Just the right amount of information for an introductory course.

By Hanna Loboda on 9/22/2020

Not happy with the labs, terrible formatting issues each time I copy paste the code from text file provided. Wish there was a way to load all the yaml files into my GCE and use it from there.

By Dheeraj Kandula on 9/21/2020

Rushing through a lot of technical jargon without explaining what they are.

By Daniel Florez on 9/20/2020

The course seems to need updates since Google Cloud Console has had some changes made to it that make it more of a challenge to keep up with the lessons, especially since it seems that my environment is not the instructor's same environment, which has led to issues with starting pods due to insufficient CPU since setup of the learning environment on Google has changed enough. The course didn't mention that every command and file input that is run in the videos is included in the text file, I happened to find that by pure curiosity but would have been great being explicit about that.

By Brian Chang on 9/17/2020

SW folks are pretty precise, indirection means different thing from abstraction, bare metal specifically moves to polling instead of scheduling to improve efficiency. i.e. no OS. Any inaccuracies will stand out and bug the audience for a little while, so when they are spaced out through out the course, it becomes hard to focus on the message itself. Others may be better adjusted to accents, but the heavy Indian accent is not the best way to present the material. I am only 10 minutes in. I hope as he goes deeper he gets more in his zone for him to be precise enough for SW folks.
