Automating stateful apps with Kubernetes Operators simplifies management of complex workloads by handling critical tasks like scaling, backup and failover automatically. This reduces downtime and human errors that are common in manual deployment processes. By Keval Bhogayata.
Kubernetes controllers are mostly applicable when it comes to managing simple apps. But when dealing with complex or stateful apps, they have limitations. These native controllers cannot automate application-specific operations and workflows, making it difficult to manage tasks like database provisioning, upgrades, and failover reliably.

While Operators automate many tasks, teams still need robust monitoring and alerting solutions to ensure apps are working as expected. Observability tools provide the visibility needed into app performance and stability that bridges automation with assurance. By integrating observability with Operators, Kubernetes can truly become a resilient platform. Excellent read!
