Project Scalability

Now, we need to test the project scalability. For that we are going to perform load testing and spike testing using Apache JMeter.

Points to be covered:

Load test plan

• Hardware resource usage estimation
• Number of users
• Expected throughput at each microservice
• Estimated usage of resources

Spike Testing

• System’s capacity limits (at what load do you get significant failure rates).
• Improvements that can demonstrate increased capacity.
• Increase service instances from 3 per service to 5 instances per service for above two measurements for throughput and for failure rates.

Understanding load testing

• How many requests can you process per second
• Improve the throughput

Understand fault tolerance:

• Why system continues to run even with injected failures.
• What is the impact on performance, compared to your previous load tests?

User experience and client-side performance
