Nordstrom Case Study: DevOps is High-Fashion: Nordstrom’s Use of Service Virtualization for Agile Parallel Development
Nordstrom implemented service virtualization as a strategic tool to enhance collaboration between its development and operations teams while addressing challenges in environment stability and project timelines. By virtualizing 80% of environment components, they achieved significant improvements including reduced dependencies, cost savings, and the ability to conduct parallel development and continuous testing. This approach has led to better resource utilization and more agile delivery pipelines, supporting the company's evolving technological needs.
