Design Microservices Architecture with Patterns and Principles - Microservices Health Checks: Liveness, Readiness, and P

The video tutorial discusses the importance of health checks in microservices, which help monitor the health and performance of individual components in a system. It explains the three types of health checks: wireless, readiness, and performance checks. Wireless checks ensure a microservice is running, readiness checks confirm it can handle requests, and performance checks assess its efficiency. The tutorial emphasizes the need for quick issue identification and resolution to maintain system reliability and suggests using health events for informed decision-making and creating self-healing services.

Why is it crucial to monitor the health of individual microservices?

• To ensure the entire system is always online

• To increase the speed of the system

• To prevent cascading failures in the system

• To reduce the cost of system maintenance

What is the primary purpose of a liveness check in microservices?

• To assess the security of a microservice

• To check if a microservice is ready to handle requests

• To monitor the performance of a microservice

• To determine if a microservice is still running

What does a failed readiness check indicate about a microservice?

• The microservice is performing optimally

• The microservice is not running

• The microservice is not ready to handle traffic

• The microservice is secure

Which type of health check would you use to monitor response times and error rates?

• Liveness check

• Readiness check

• Performance check

• Security check

What is a potential benefit of implementing health checks in microservices?

• Faster system shutdowns

• Elimination of all system errors

• Reduced need for system updates

• Increased system visibility and reliability
