Kubernetes is a powerful platform for orchestrating distributed computing but presents challenges when integrating legacy, stateful applications not built with its paradigm in mind. Stateless applications are better suited for Kubernetes, while stateful applications require careful consideration of clustering, replication, and persistence. The platform's evolution has improved support for external storage, but issues like distributed system fallacies and the complexity of containerizing existing applications persist. Modern solutions and tools, such as Apache Kafka and Portworx, address some of these challenges, while capabilities like the Horizontal Pod Autoscaler aid in process scaling. Developers are encouraged to adopt an incremental approach, starting with stateless applications and gradually incorporating more complex workloads, using platforms like Harness to manage deployments across diverse infrastructures.
