Canary and Blue-Green Deployment Strategies

1. A canary deployment that increases traffic by 10% every 5 minutes is using which strategy?

Instant switch

Linear traffic ramping

Shadow traffic

Fixed percentage split

Submit

5. What is the primary challenge of maintaining two full production environments in blue-green deployments?

Increased operational complexity and resource costs

Slower deployment speed

Inability to perform rollback

Loss of monitoring capability

6. How does a canary deployment reduce deployment risk compared to traditional full rollouts?

By skipping automated tests

By limiting blast radius and enabling quick rollback on issues

By eliminating monitoring

By requiring more manual steps

7. In AutoOps+ canary deployments, what is a 'soak period'?

Time spent debugging failures

Duration the canary runs at current traffic level before increasing

Database synchronization time

Server warm-up period

8. Which scenario best justifies using a blue-green deployment over canary?

Testing with a small subset of users

Major database schema changes requiring instant cutover

Minor API endpoint updates

Gradual feature rollout

9. In blue-green deployments, session persistence becomes critical when which event occurs?

During initial deployment

During the traffic switch between environments

After 7 days

During database migrations

10. What is the primary benefit of using a shadow deployment before canary?

Eliminates all risk

Allows testing new version without impacting live users

Reduces infrastructure costs

Speeds up deployment by 50%

11. What is the primary advantage of a canary deployment over a full production release?

Immediate rollout to all users

Gradual rollout to a subset of users to detect issues early

Requires no monitoring infrastructure

Eliminates the need for automated testing

12. Which observability tool component is essential for canary deployment success?

Email notifications only

Real-time metrics, logs, and traces from both versions

Weekly reports

Manual log review

13. In a blue-green deployment, the inactive environment is typically used for what purpose before switching?

Backup storage

Testing the new version with production-like data

Running batch jobs

Serving static assets

14. What does 'traffic shifting' mean in the context of canary deployments?

Moving users between geographic regions

Gradually routing a percentage of requests from stable to new version

Switching all traffic at once

Distributing load across multiple data centers

15. Which deployment strategy allows immediate traffic switch with zero gradual rollout?

Canary deployment

Rolling deployment

Blue-green deployment

Shadow deployment

16. In AutoOps+, automated rollback in a canary deployment is typically triggered by which condition?

Manual operator decision

Predefined threshold breach in error rate or latency

Passage of 24 hours

User complaint submission

17. What is a key disadvantage of blue-green deployments compared to canary deployments?

Higher infrastructure costs due to duplicate environments

Slower rollback capability

Inability to run automated tests

Requires manual traffic switching

18. A canary deployment typically starts by routing traffic to the new version to what percentage of users?

50%

100%

5% to 10%

25%

19. Which metric is most critical when monitoring a canary deployment?

CPU utilization

Error rate and latency compared to stable baseline

Disk space usage

Number of concurrent connections

20. In a blue-green deployment, what do the terms 'blue' and 'green' represent?

Different geographic regions

Two identical production environments with different versions

Development and staging environments

Active and inactive database clusters
