Service Dependencies and Order
The three core services have dependencies that dictate the restoration order:
Consul should be restored first, as it contains:
-
Service discovery information
-
Configuration key-value pairs
-
Service mesh configurations
-
ACL tokens and policies
PostgreSQL should be restored second, containing:
-
User authentication data
-
Application state and transactions
-
Relational data with referential integrity
-
Audit logs and operational data
Elasticsearch should be restored last, as it contains:
-
Search indices
-
Log data and analytics
-
Time-series data
-
Cached and derived data
This order ensures that configuration and authentication systems are available before application data is restored.
