This blog post comes with the third video of the Multi-Part Video Series on “Oracle Exadata Cloud Service for DBAs & Apps DBAs”. In this post, I’ll be discussing the Deployment Options available for Exadata i.e. Cloud Service (ExaCS), Cloud at Customer (ExaCC) and Exadata Machine.

Deployment Options
There are three deployment options available for Exadata:
- Exadata Cloud Service (ExaCS)
- Exadata Cloud at Customer (ExaCC)
- Exadata Machine
Let’s see the difference between these deployment options in brief.
- Exadata Management. In the traditional On-Premise Exadata, Exadata Database Machine is in the client’s datacentre and is the client’s responsibility to manage the Exadata hardware with Oracle. However, in ExaCS and ExaCC, Oracle manages the Exadata hardware and firmware and the client manages the Exadata operating system and the database.
- Data. In On-Premise Exadata Machine and ExaCC, the Exadata runs within the client’s datacentre but in ExaCS, Exadata is deployed on Oracle’s Public Cloud in one of the available regions such as US, Japan, South Korea, UK, Germany, etc i.e. in ExaCS, data doesn’t stay in the datacentre of the client.
Note: The client can restrict the data to a specific region in ExaCS.
- Services. No Cloud services are offered for On-Premise Exadata Machine. However, in ExaCC and ExaCS, Oracle provides the client with Cloud services such as Cloud Control Plane, Advanced Support Gateway, Oracle Object Storage instance, Cloud Tools, etc. Additionally, in ExaCC, Oracle Advanced Support Gateway service is provided.
- Model. In On-premise, the Exadata Database Machine is provided on the purchased-based but in ExaCC and ExaCS, Exadata is used as a service and are provided on the subscription-based model by Oracle.
Note: One can purchase a Compute Machine On-premise to create other machines, to deploy other Cloud instances like Java Service Cloud or SOA Cloud Service or Compute.
Why Is Cloud Control Plane Important?
Cloud Control Plane is a Cloud software which manages billing, identity, REST services, compute, storage, etc. Cloud Control Plane also manages other Cloud services running on the datacentre.
Note: Only one Control Plane is required for each datacentre, irrespective of the number of the Cloud Instances.
What Is The Role Of Oracle Advanced Support Gateway in ExaCC?
Architecture of ExaCC
The Oracle Advanced Support Gateway is used to send Exadata monitoring data to Oracle Support Team. In return, Oracle Support Team remotely manage Exadata Hardware, Patching Firmware, Infiniband Network via VPN to ensure the proper functioning of Exadata.
Why Should A Client Choose ExaCC Over ExaCS?
Here are a few reasons why the client should pick ExaCC over ExaCS:
- Data Residency Law. ExaCC follows the Data Residency Law in which the data remains only at the datacentre of the server.
- Security. Since the data resides in the datacentre, there is no risk of a security breach. The data is relatively more secure in an ExaCC.
- Complication. Clients may find it difficult to lift and shift to the Cloud. But in ExaCC, the client doesn’t have to shift their complicated systems to the Cloud. They can avail the Cloud services at their own datacentres.
