Organizations have practiced application performance management and monitoring for as long as there’s been software. Over the years it has evolved and changed to accommodate different methodologies like Agile, but traditional monitoring and testing can’t keep up with the new paradigms necessary for cloud-native applications built using containers and with microservices. That’s where observability comes in. As software architectures become more complex, observability has become an essential part of the testing environment to help identify and resolve issues early on in the development life cycle. Ultimately, testing and observability share the same goal: To make sure systems are running smoothly.
