About

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 a 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 migration. Multi-cloud: this refers to the use of more than one 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 AWS customers, who decided that 'multi-cloud' makes sense for strategic reasons). The only straightforward way is when cloud providers offer a range of compute solutions, ranging from PaaS (Elastic Beanstalk, or Google App Engine) to IaaS (EC2, or Google Compute Engine VMs). The reality is that PaaS ties you down to one 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.

Style and Approach

Kubernetes is a container orchestration technology - a way to create and deploy clusters of machines running containers, usually Docker containers.

Features
  • Docker, Kubernetes and the cloud platforms: 
  • Understanding the inter-relationships
  • Pods and containers: Pods are the basic building block in K8S
  • Each pod holds one or more containers that are tightly-coupled to each other
  • ReplicaSets: Higher-level abstractions that provide scaling and auto-healing (they encapsulate pods, and bring new pods back up if the old ones crash)
  • Deployments: Even higher-level abstractions that provide versioning, fast rollback, rolling updates and more.
  • Services: 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-balancing
  • Other K8S objects: StatefulSets, Secrets, ConfigMaps, Jobs and CronJobs and more
  • CKA test tips: We don't reveal any information about the test that we should not, such as specific questions

Loonycorn is Janani Ravi and Vitthal Srinivasan. Between them, they have studied at Stanford, been admitted to IIM Ahmedabad, and have spent years working in tech, in the Bay Area, New York, Singapore and Bangalore. Janani spent 7 years at Google (New York, Singapore); Studied at Stanford and also worked at Flipkart and Microsoft. Vitthal also worked at Google (Singapore) and studied at Stanford; Flipkart, Credit Suisse and INSEAD too. They think they might have hit upon a neat way of teaching complicated tech courses in a funny, practical, engaging way, which is why they are so excited to be here. They hope you will try their offerings, and you'll like them.
