Architecture change- service resources- Add cosmos db and Storage account

Additional cosmos DB and Storage account is needed to in services resource group to support shared schemas. This database/ SA would be in addition to all the partition specific cosmos dbs/ SAs

Design

  1. We already have a module for cosmos db. The same can be leveraged to create cosmos db in service resources.
  2. We already have a module for Storage account. The same can be leveraged to create Storage Account in service resources.

Module Requirements

  • Required modules are already present

Template Requirements

  • Database will be named with the suffix of "system" to distinguish from table or db

  • Database will be created as part of the service Resource Template

  • Database will be locked

  • Database location and replication location will be consistent in naming patterns to Data Partitions

  • Database by default will use the same type of throughput settings as other CosmosDBs.

  • Storage account will be named with the suffix of "system" to distinguish from other SAs

  • Storage account will be created as part of the service Resource Template

  • Storage account will be locked

  • Storage account location and replication location will be consistent in naming patterns to Data Partitions

Acceptance Criteria

  1. Architecture Diagram Change
  2. Modify Central service to add the additional database/ SA.
  3. Ensure all Module Unit Tests Pass
  4. Ensure all Template Unit Tests and Integration Tests Pass
  5. Update all required documentation
