Validating Backend Modernization Through Front-End Performance Testing with Octoperf
We are launching with this post a new series of blog articles and LinkedIn posts titled "Feedback From the Field".
Defion, our partner based in the Netherlands and Spain (formerly "Computest"), is kicking things off with this project testimonial.
Enjoy the read.

Modernization Is Not Just an Infrastructure Exercise
A financial institution recently initiated a backend modernization program, transitioning from legacy components to a more scalable, service-oriented architecture.
The objectives were clear:
- Improve scalability and resilience
- Enable faster feature development
- Reduce operational complexity

The key question became:
Does the new backend architecture translate into stable and responsive user-facing systems under real-world load?
