SugarCRM Database Deployment Variants DB in separate Service Template DB external to Service Template

Objective Consider scenarios when components or services required by a deployment may be: – 1) Shared across deployments – 2) Already existing/provided by a 3 rd party not part of any existing Service Template (i.e. under the control of a separate and autonomous administrative entity) 2

When To Split? DB has a different lifecycle than the PHP App – E.g. DB is really shared across multiple client apps DB service is offered by a different Administrative Entity (AE) – DB AE controls lifecycle of the DB. PHP AP AE consumes DB on DB AE’s terms – AE for App and DB both use TOSCA gaining the benefit the awareness of each other’s models Lifecycle awareness Federation 6

Using an “External” DB Single Service Template specifies: – PHP App fully specified as part of deployment as a complete tier – DB is partially specified DB is hostedOn a DBMS (R3) DBMS instance is specified (C3) – Address and port – DBMS type not necessarily relevant (leave abstract if possible) DBMS container/tier is out of scope TOSCA engine must resolve lifecycle states of DBMS 7
