About this document

This document provides suggestions for how to setup xenon based application system in various use cases.

Blue/Green deployment

TBD

see Side-by-Side-Upgrade

Multiple GEO system

Use Case

  • cross datacenter replication (east coast, west coast)

TBD

Active/Standby with different node group

Scenario

Two node groups: ACTIVE and STANDBY. ACTIVE group receives all requests. STANDBY group receives data in near real time and both systems will have identical data.

Use Case

  • backup node group
  • usage for read transactions such as data warehouse

Recommendation

Continuous Migration

Use MigrationTaskService to periodically pull all data from ACTIVE to STANDBY. MigrationTaskService has continuousMigration flag that will continuously query data and reflect to STANDBY node group.

Manual Replication

Subscribe to a service, then manually replicate to a service associated with the other node group (issue updates, in a eventual way)

Multiple nodegroup system

Scenario

Read operation intensive system

Scenario

Use Case

  • high traffic contents oriented website such as blogs
