|Optimized for administrators deploying and maintaining cluster-wide services.
|Some scope for customization. Charts allow users to provide values specific to their environment.
|Greater scope for customization. More complex operations, workflow and event-driven automation, lifecycle management can be added.
|Shorter development time to build.
|Longer development time to build. Operator SDK provides tools to assist in the process.
|Good for day-1 operations such as installing the application and performing simple updates.
|Provides a broad spectrum of day-1 and day-2 automation capabilities, for full lifecycle management of the application.
