Use Oracle Integration to connect E-Business Suite with SOA to Financials Cloud

Blog: PaaS Community


Most deployments of Oracle E-Business Suite are integrated with other commercial or bespoke applications so companies can run their processes with agility. Oracle software-oriented architecture (SOA) Suite is a popular choice to provide integration to EBS for its broad connectivity options and EBS Adapter capabilities.

When you move your applications to the cloud, there are more opportunities to modernize and integrate with other cloud services and SaaS applications. Oracle Integration takes integration and connectivity capabilities beyond yet reusing what is developed and running on SOA Suite.

This architecture presents the end state of moving an EBS instance to OCI along with the integration built with SOA Suite in a secure setup and the components needed to connect Oracle Integration with SOA Suite and EBS. This architecture also shows integration with Oracle Financials Cloud.


This architecture shows the deployment of Oracle E-Business Suite in a single availability domain inside a single Oracle Cloud Infrastructure region, along with existing integrations built using Oracle SOA Suite. Oracle Integration connects to SOA using the Integration connectivity agent to provide reuse of integrations built with SOA and connectivity to other SaaS applications and cloud technologies.

The architecture includes two compartments, both of which have Cloud Guard enabled to provide maximum security based on Oracle’s security best practices. In addition, the compartment where the database system and the autonomous database private endpoint are deployed is a security zone compartment.

Each compartment contains a virtual cloud network (VCN), which are connected through a local peering gateway, allowing network traffic between the two. Components are in different subnets and fault domains to provide high availability. The databases are accessed only through the bastion host and the application virtual machines (VMs) are accessed through the load balancers.

The database and the application instances that are deployed in their private subnets on OCI are backed up to OCI Object Storage by using a service gateway. A service gateway provides access to Object Storage without traversing the internet. You can use the automatic and on-demand database backups feature to back up applications and the database.

Use a network address translation (NAT) gateway to enable outbound connection from the application instances in the private subnets to the Internet to download patches and apply operating system and application updates. With a NAT gateway, the hosts in private subnet can initiate connections to the Internet and receive responses, but don’t receive inbound connections initiated from the internet.
