Look inside

You’re the new Kubernetes administrator at Interpop, a popular music streaming service that receives about a million requests per second. Your task is to help Interpop provide the high level of service that its customers expect by keeping its microservices running optimally. You’ll set resource requests and limits, ensuring enough CPU and RAM are available to ensure efficiency. You’ll “soup up” the app, preventing it from failing to run by using selectors and affinity for pod scheduling. Using Helm to install multiple Kubernetes resources at once, you’ll streamline the task of routing incoming requests to multiple Kubernetes services. When you’re done, you’ll be hitting a high note with your expertise in keeping Kubernetes services highly available and fault-tolerant.

This project is designed for learning purposes and is not a complete, production-ready application or solution.
