Most organizations prefer to deploy containerized applications into K8s because of its scalability and flexibility. But as the number of microservices increased and application pods are distributed across multiple clusters and cloud providers, managing and scaling them has become complex.
While scaling, it is harder to configure complex communication logic between microservices. Also, there are additional concerns like securing and observing these connections. Without a proper management system for communication, service downtime and security breaches among distributed services become common.
