In a sea of virtualized layers of abstraction, shared services, and dependencies, the cloud has become increasingly complex. Our platform needed a full-stack approach, including virtual network infrastructure, containers, applications, and users. We knew APM was critical but no longer enough. We needed to go beyond APM.
