Cloud Native applications have revolutionized how businesses function, providing unprecedented agility and scalability. Observability, application performance monitoring, and testing (APM/T) practices have become more crucial in distributed, scalable microservices across multiple clouds. However, harnessing their full potential in Kubernetes and Multi-Cloud Environments can be challenging. We propose a panel discussion highlighting the importance of observability and APM/T for managing and improving microservices in a multi-cloud environment.
