The PAC aims to promote engagement between various experts from around the world, to create relevant, value-added content sharing between members. For Neotys, to strengthen our position as a thought leader in load & performance testing. Since its beginning, the PAC is designed to connect performance experts during a single event. In June, during 24 hours, 20 participants convened exploring several topics on the minds of today’s performance tester such as DevOps, Shift Left/Right, Test Automation, Blockchain and Artificial Intelligence.

8. Performance Risks of Re-platforming (to Cloud)
▪ Don’t go big-bang
- Select suitable application to use as re-platforming pilot
▪ Not baselining existing application performance
- High risk if unable to perform a before and after performance comparison
▪ Insufficient resilience
- Take time to define and POC your DR provision

9. Re-architect

10. Monolith to Modular

11. Performance Risks of Re-architecting
▪ Container and microservice sprawl
- Too many, uncurated, unmanaged, uncontrolled
▪ Not following coding and configuration best practice
- New technology choices are great but don’t overlook best practice.
▪ Performance test components and services early rather than late
- Reuse, repurpose of components widens risk of performance defect impact

12. Manage the UX

13. Manage the UX – Monitor, Measure, Inform, Tune
▪ Monitor the UX
▪ Measure the quality
▪ Inform the Business
▪ Tune to optimise the UX

14. Performance Risks of not Managing the UX
▪ Insufficient monitoring coverage
- Disconnected from the UX – Consider APM (DynaTrace, Appdynamics, New Relic)
▪ EUE quality more than just first mile - > last mile
- Regular review of 3rd party affiliate and service impact on performance
▪ End user behaviour awareness
- Drives business ability to react to change, BI data mining easier than ever so take full
advantage

15. Visualise Performance
▪ Very important for performance awareness
▪ Feedback loop into Business and Dev
▪ Dashboard latest results and trends
▪ Keep it simple – Summary and drill-down
▪ Automate
- ELK, Grafana
