Why production readiness matters in Kubernetes - Quick Recap

Recall & Review

beginner

What does 'production readiness' mean in Kubernetes?

Production readiness means that your Kubernetes setup is stable, secure, and reliable enough to run real applications that users depend on every day.

beginner

Why is monitoring important for production readiness?

Monitoring helps you see how your apps and cluster are doing in real time, so you can fix problems before users notice.

intermediate

What role does automated testing play in production readiness?

Automated tests check your app and infrastructure automatically to catch bugs early, making your system more reliable.

beginner

How does security relate to production readiness?

Security ensures your Kubernetes cluster and apps are protected from attacks, keeping user data safe and services running.

beginner

What is the impact of not being production ready?

If you are not production ready, your apps might crash, lose data, or expose sensitive info, causing unhappy users and lost trust.

What is a key sign that a Kubernetes cluster is production ready?

A It has monitoring and alerting set up

B It runs only one pod

C It has no backups

D It uses default passwords everywhere

Monitoring and alerting help detect and fix issues quickly, which is essential for production readiness.

Why should you automate testing before deploying to production?

A To make deployment slower

B To catch errors early and avoid downtime

C To increase manual work

D To ignore security checks

Automated testing finds problems early, reducing the chance of failures in production.

Which of these is NOT part of production readiness?

A Ignoring logs

B Regular backups

C Security hardening

D Load balancing

Ignoring logs means missing important information about system health, which harms production readiness.

What happens if your system is not production ready?

A You get more users automatically

B Everything works perfectly

C You save money on infrastructure

D Users may experience crashes and data loss

Lack of readiness can cause failures that affect users negatively.

Which practice improves production readiness in Kubernetes?

A Skipping backups

B Disabling security policies

C Implementing health checks for pods

D Using default configurations without review

Health checks help Kubernetes know when to restart or replace unhealthy pods, improving reliability.
