Performance Testing for Digital Channels

Ensuring Uptime Under Extreme Traffic

Modern microservice architectures solve scaling problems but introduce complexity in monitoring transaction latency. This article shares key best practices for performance testing.

1. Defining the Load Profile

Before launching a test, analyze production logs to understand real-world transaction mix (e.g. 70% queries, 20% transfers, 10% payments).

2. Internal Latency Monitoring

Determine if delays occur at the API Gateway level, in the business logic processing layer, or in database locks. Profiling is essential.

3. Simulating Real Network Conditions

Load tests should introduce latency and packet loss to simulate real-world mobile connection behaviors of end-users.
