Master Microservices with Spring Boot and Spring Cloud - Step 10 – Quick Review of Kubernetes Concepts – Pods, Replica S

The video tutorial explores key Kubernetes concepts, including pods, replica sets, and deployments. Pods are containers' wrappers with unique IPs, while replica sets ensure a specified number of pods are always running. Deployments facilitate seamless application upgrades without downtime, using strategies like rolling updates. Kubernetes' complexity is acknowledged, but mastering it makes it a powerful tool, widely adopted by cloud platforms and enterprises. The tutorial concludes with a teaser for the next topic: services.

What is the primary role of a pod in Kubernetes?

• To act as a wrapper for containers

• To provide security features

• To manage network traffic

• To store application data

How does a replica set ensure availability in Kubernetes?

• By scaling up the application

• By maintaining a specified number of pod instances

• By providing load balancing

• By managing network policies

What is the main purpose of a deployment in Kubernetes?

• To provide security updates

• To monitor application performance

• To facilitate seamless application upgrades

• To manage storage resources

Which deployment strategy involves gradually replacing old instances with new ones?

• Blue-Green Deployment

• Recreate Strategy

• Canary Deployment

• Rolling Update

Why is Kubernetes widely adopted by enterprises?

• Due to its limited features

• Because it is the cheapest option

• Due to its support by multiple cloud platforms

• Because it is easy to learn
