Planning Database as a Service Implementation Project

People, process and planning are the three key elements to success in a private cloud journey. Some common questions i hear from field/customers often relates to tasks involved in setting up Database-as-a-Service(DBaaS) using Oracle Enterprise Manager 12c from scratch and how these tasks are mapped to current IT roles and responsibilities - overall list of activities that needs to be performed to setup and achieve DBaaS and who does what during the implementation process.

In terms of roles, responsibilities and users, you will map to these categories

  • Project Manager is responsible for working with all stakeholders, project team and coordinating in planning and delivering DBaaS implementation project
  • EM Admin sets ups Cloud management infrastructure and is responsible for overall EM 12c installation/configuration and Administration
  • Cloud Admins are responsible for managing the Cloud infrastructure(Servers, Network, Storage) and related Administration
  • SSA Admins or Cloud DBAs are responsible for Self Service portal setup, managing quotas, policies, target DBs S/W provisioning/ongoing Administration
  • SSA Users or End users of Cloud who actually requests for DB instances to be rapidly provisioned on-demand from Self Service portal


Here is a sample Work-breakdown structure(WBS) listing down tasks involved and with individual owners mapped. Note - we have all type of use cases covered in the plan (DBCA, RMAN, Schema as a Service, Snap Clone) and you can pick up any or mix or all of these tasks in your plan depending on your use cases and requirements for implementing DBaaS -
