Course End Projects:

Project 1: IT Software Containerization

As a Kubernetes developer demonstrate the packaging of your web application in a Docker
container image. Use the container image on Google Kubernetes Engine cluster as a
load-balanced set of replicas that can scale to the needs of your users. Scale a deployed
application in Google Kubernetes Engine then deploy a new version of your app without
having zero down time and finally deploy it to the cluster.

 

Project 2: Social Media underlying infra challenges

As a Kubernetes Developer, complete the features of the application Scalability by
demonstrating how to create Cluster with auto scale feature, How to resize the existing
cluster size in order to meet infra requirements of already running application in production,
& Finally how to auto scale the application in terms of Replica set and deployments.
