17 . 01 Motivation 

18 .Motivation Dashboard VS Pulsar-manager • Focus on management • Focus on simple monitoring • Simple monitoring • Weak management • Multi-cluster, multi-environment • Multi-cluster is not management • More suitable for cloud supported • JWT authentication authorization and management • Deployment simple 

19 . 02 Operation 

20 .Operation 

21 .Multiple environments 

22 .Multiple clusters • Geo replication • Global tenants, namespace • Topics management by cluster 

23 .Clusters management • Set basic configuration • Set failure domains • Isolation policies 

24 .Clusters management 

25 .Tenants management • Create Tenant • Delete Tenant • Update Configuration 

26 .Tenants management 

27 .Namespaces management • Create Namespace • Delete Namespace • Update Policies 

28 .Namespaces management 

29 .Topics management • More info(Storage, segment, cursor) • Create Topic(Persistent, non-persistent) • Delete Topic • Update Configuration • Topics monitor(Aggregated data)
