As organizations rushed to embrace digital business transformation initiatives in the last year in response to rapidly changing economic conditions, the number of mission-critical applications that now need to be managed has increased significantly. A large percentage of those applications are based on a microservices architecture that, while being more resilient and flexible than legacy monolithic applications, are a lot more difficult to manage. Each microservice has dependencies on other services that it invoked over an application programming interface (API). Those dependencies span the underlying infrastructure, other microservices, and monolithic applications that may be running on the same cloud, in another cloud, or in an on-premises IT environment.All of those dependencies are forcing IT organizations to revisit how they monitor those increasingly complex environments.
