How SNCF Connect & Tech migrated their infrastructure to the Cloud and increased developer autonomy with Gatling Enterprise

SNCF Connect & Tech efficiently manage large network traffic, but with the increasing number of sessions/second and constantly changing government policies for ticket management, managing network traffic efficiently and continuing to provide impeccable customer service became their priority.

Until 2018, with their previous load testing tool, the organization's developers had limited autonomy to manage their projects. Testers struggled with transferring performance-qualifying processes to the project teams, relied heavily on the tool, and struggled to manage their teams, backlogs, tests, etc.

The organization searched for a tool specializing in load testing for developers that provides autonomy, regularly checks the application's performance, and enables them to migrate part of their infrastructure to the cloud without performance issues and with lower costs.

In 2018, they deployed a self-hosted Gatling Enterprise integrated with Maven to test how the application behaved when many sessions/second were open during the sale of online tickets. For 300+ projects, they conducted soak tests to assess applications' stability and peak tests to evaluate applications’ behavior when faced with high traffic.

SNCF Connect & Tech commenced their infrastructure migration in 2020 with the help of hybrid AWS infrastructure. Further, they deployed resources to build a community of agile developers with Gatling to support their projects through this infrastructure migration process and completed the transition process in 2021.

Gatling's Community within SNCF Connect & Tech created a knowledge base and boot camps around load testing. The community empowered 50+ developers to be more agile and autonomous. A trained team can script, launch, and run a simulation in less than three days. Also, the developers can now easily update test scenarios, generate several tests throughout the day, and implement an Application Programming Interface (API) for retrieving and comparing test results.

Today, SNCF Connect & Tech can successfully manage 120 terabytes of data per month with more than 2.5+ million website visits daily and 25+ million downloads of the SNCF Connect & Tech application, with low infrastructure costs.
