These development and testing practices ensure the performance of critical applications and resources to deliver loyalty-building user experiences. Because pre-production environments are used for testing before an application is released to end users, teams have no access to real-user data. What is synthetic monitoring?

As patient care continues to evolve, IT teams have accelerated this shift from legacy, on-premises systems to cloud technology to more build, test, and deploy software, and fuel healthcare innovation. Amid so much change, teams can no longer rely on time-consuming, manual approaches for building, testing, operating, and upgrading software.
