You are currently viewing version 1.3 of the Apigee hybrid documentation.This version is end of life. You should upgrade to a newer version. For more information, seeSupported versions.

This section explains which data is stored in your local runtimeplane for Apigee hybrid, and which data is maintained in the management plane (in theApigee Cloud).

Data stored in the runtime plane

You manage the runtime plane services, including data stored in theruntime plane. The following data is stored by the runtime Cassandra (and accessed from or by the management plane through MART):

• Key management system (KMS) data, including companies, developers, developer apps, API products, OAuth tokens (including access and refresh tokens, and authorization codes), and API keys
• Key value map (KVM) data (can be created/managed using KVM policies)
• Environment cache data
• OAuth data, including access tokens, refresh tokens, and authorization codes
• Quota data, including buckets and counters

For information on securing data in your runtime plane, seeSecuring the runtime installation.

Data stored in the management plane

The following data is stored in the management plane:

• API proxies
• TargetServers
• Truststores and keystores

You create these entities in the management plane (for example,in the hybrid UI or with theApigee APIs), and the related data isreplicated in the runtime plane by the Synchronizer, which pullsthis data down and stores it in the runtime plane where the MP canaccess it.

For more information, seeSynchronizer.

Data sent from the runtime plane to the management plane

The runtime plane sends the following data (asynchronously) tothe management plane:

• Analytics
• Deployment status events
• Debug data

Data sent to Stackdriver for your Google Cloud project

• Log data
• Metrics

Data stored only in the management plane

• Audit logs
• RBAC
• Users

For information about the various types of data generated by thehybrid services, and the mechanisms by which hybrid collects andsurfaces this data to you, seeData collection overview.
