About Client:

The client is a global technology leader providing critical infrastructure software solutions that power the world's most demanding enterprises. With a vast portfolio built through strategic acquisitions and organic growth, the company delivers mission-critical software spanning diverse areas like enterprise operations management, cybersecurity, and automation. They serve a wide range of industries, including major financial institutions, telecommunications providers, and government agencies, enabling them to manage complex IT environments, ensure resilience, and drive digital transformation initiatives at a massive scale. Maintaining and modernizing their extensive software stack, often involving multiple underlying technologies, is crucial for their continued success and customer satisfaction.

Overview:

This case study details a strategic frontend modernization initiative focused on the widely-used Grafana observability platform, which was integral to the client's internal monitoring and potentially customer-facing reporting solutions. Over time, Grafana's evolution led to a mixed frontend codebase, with legacy elements built using Angular (often AngularJS or earlier Angular versions) coexisting alongside newer React components. This heterogeneity presented challenges in maintainability, performance consistency, and developer productivity.

DEFTeam was engaged to execute a complex migration project, converting key components from Angular to React. The scope was significant, encompassing not only specific Grafana plugins (custom or community-based ones critical to the client's workflows, built on Angular) but also potentially touching elements within the core Grafana application framework itself where Angular was still present or where plugin interactions required framework-level adjustments. The primary objectives were to standardize the frontend on React, eliminate technical debt associated with the legacy Angular code, improve overall application responsiveness and user experience, and create a more unified and efficient development environment for teams working within the Grafana ecosystem. This migration was essential for aligning the platform with modern web development standards and ensuring its long-term scalability and maintainability.
