Why Kubernetes manages microservice deployment in Microservices - Quick Recap

Recall & Review

beginner

What is the main reason Kubernetes is used to manage microservice deployment?

Kubernetes automates the deployment, scaling, and management of microservices, making it easier to handle many small services reliably.

beginner

How does Kubernetes help with scaling microservices?

Kubernetes can automatically add or remove instances of microservices based on demand, ensuring the system runs efficiently.

What role do containers play in Kubernetes managing microservices?

Containers package microservices with everything they need to run, and Kubernetes manages these containers to deploy and run microservices consistently.

intermediate

Why is self-healing important in Kubernetes for microservices?

Kubernetes can detect when a microservice instance fails and automatically restart or replace it, keeping the system healthy without manual work.

intermediate

How does Kubernetes simplify updates and rollbacks for microservices?

Kubernetes supports rolling updates, allowing microservices to be updated without downtime, and can roll back changes if problems occur.

What does Kubernetes primarily manage in microservice deployment?

A Containers running microservices

B Only the database connections

C User interface design

D Hardware maintenance

Kubernetes manages containers that run microservices, handling deployment, scaling, and health.

How does Kubernetes handle a failed microservice instance?

A It sends an email to the user

B It ignores the failure

C It automatically restarts or replaces the instance

D It shuts down the entire system

Kubernetes self-heals by restarting or replacing failed microservice instances automatically.

What feature allows Kubernetes to update microservices without downtime?

A Full system reboot

B Manual restart

C Static deployment

D Rolling updates

Rolling updates let Kubernetes update microservices gradually to avoid downtime.

Why is scaling important in microservice deployment with Kubernetes?

A To change the color of the UI

B To increase or decrease microservice instances based on demand

C To reduce the number of developers

D To backup data manually

Scaling adjusts the number of microservice instances automatically to match user demand.

What does Kubernetes use to package microservices for deployment?

A Containers

B Virtual machines

C Physical servers

D Spreadsheets

Containers package microservices with their dependencies for consistent deployment managed by Kubernetes.
