When you subscribe to Oracle’s Infrastructure as a Service (IaaS), you have access to all the compute, storage, and network services associated with it, to be used as you wish. If necessary, you can also subscribe to the Oracle Database Cloud Service (DBCS) and take advantage of the specific features and capabilities of this offering.
You can choose the most suitable deployment option for your business needs, as follows:
The single node on IaaS option consists of an all-in-one Oracle E-Business Suite Release 12.2.5 machine image that includes both the application tier and the database tier. Available on Oracle Cloud Marketplace, this image is updated when required, so you can quickly provision the latest image to explore new features.
This option is ideal if you wish to evaluate and test standard Oracle E-Business Suite functionality, and become familiar with the technology components and other features.
The multiple nodes on IaaS option allows you to provision one or more application tiers, plus a separate database tier, on the Oracle Compute Cloud Service. You can scale out the application tier as needed, and an automated provisioning tool enables you to create a new installation of Oracle E-Business Suite across Oracle Compute Cloud Service instances.
The flexibility of this option makes it ideal for supporting production workloads, as well as development, testing and training environments in all types of Oracle E-Business Suite installation:
The third option is a variant of the multiple nodes option offered by Option 2. It comprises the same components, but does not deploy the Oracle Database within a virtual machine on the Oracle Compute Cloud Service. Instead, it uses a subscription to Oracle’s Platform as a Service (PaaS) or Exadata Cloud Service to provide the Oracle E-Business Suite database needed.
As with Option 2, you have a choice of provisioning these multi-tier instances either from the Oracle Cloud Marketplace (for demo and fresh installs) or from on-premise instances (for cloning of existing Release 12.1.3 or 12.2 instances).
