JencoMart has built a version of their application on Google Cloud Platform that serves traffic to Asia. You want to measure success against their business and technical goals. Which metrics should you track?
A.
Error rates for requests from Asia
B.
Latency difference between US and Asia
C.
Total visits, error rates, and latency from Asia
D.
Total visits and average latency for users from Asia
E.
The number of character sets present in the database
Answer is C; more complete imo. Those aligning to D should note that average latency is not the only metric available to measure and is too specific.
"Total visits" covers the business requirements:
- Optimize for capacity during peak periods and value during off-peak periods.
- Expand services into Asia.
"Error rates" covers business requirement:
- Guarantee service availability and support. ** if service is unavailable, errors are reported!
"Latency" covers technical requirement:
- Decrease latency in Asia.
I understand the Case Study is already deprecated by here is my 5 cents:
I chose C. Total visits, error rates, and latency from Asia.
Here's why this option is the most appropriate:
Total Visits: Monitoring total visits helps in assessing the application's capacity to handle peak and off-peak periods, which aligns with the goal of optimizing capacity. It also provides insight into the success of their expansion efforts in Asia.
Error Rates: Tracking error rates is crucial for ensuring service availability and support. It directly relates to the goal of guaranteeing availability by identifying and resolving issues that could lead to service disruptions.
Latency from Asia: Monitoring latency specifically for users in Asia addresses the technical goal of decreasing latency in this region. It's a direct measure of the performance improvements and user experience enhancements expected from the cloud migration.
