+# Implement Multicloud cross-region disaster recovery for Oracle Database@X (Azure, GCP, AWS)
+
+This repository allows you to deploy all the needed networking for implementing cross-region disaster recovery in oracle database@X (AWS, Azure, Google Cloud). 
+It configures all the networking detailed in the following reference architectures:
+
+- [Implement cross-region disaster recovery for Exadata Database on Oracle Database@Azure](https://docs.oracle.com/en/solutions/exadb-dr-on-db-azure/index.html#GUID-A43C87C3-C331-415A-9951-86C454C8E9C3)
+- [Implement cross-region disaster recovery for Exadata Database Service on Google Cloud](https://docs.oracle.com/en/solutions/exadb-dr-on-db-google-cloud/index.html#GUID-041B1ED9-43B8-41C3-90A6-1695668F7DB6)
+- [Oracle Database@AWS Achieves Gold MAA Certification for Maximum Availability Architecture](https://blogs.oracle.com/maa/post/oracle-databaseaws-achieves-gold-maa-certification)
+
+## Architecture diagram
+
+<img src="files/exadb-dr-db-azure.png" width="800" />
+
+## Requirements
+
+- An active Oracle Cloud Infrastructure Account.
+- An Oracle Exadata Database@X deployment in primary region and Standby region
+- API Key Authentication for OCI Terraform provider -> https://docs.oracle.com/en-us/iaas/Content/API/SDKDocs/terraformproviderconfiguration.htm
+- Terraform
+- Permission to manage virtual-network-family resources to a specific group within a compartment in your Oracle Cloud Infrastructure tenancy
+- VCN primary and VCN Standby OCIDs
+- Non-overlapping IP Addresses for Hub VCN Primary and Standby
+
+## Steps
+
+- Duplicate the "terraform.tfvars.template" file and rename it to "terraform.tfvars"
+- In the new "terraform.tfvars" file complete the "OCI Tenancy Credentials" and "Oracle Cloud Infrastructure Variables"
+
+## Deployment
+
+Create the Resources using the following commands:
+
+```bash
+terraform init
+terraform import oci_core_vcn.vcn_primary ocid1.vcn.primary-xxxxxxxxxxxxx
+terraform import oci_core_vcn.vcn_standby ocid1.vcn.standby-xxxxxxxxxxxxx
+terraform plan
+terraform apply
+```
+
+After successfully running terraform apply, the administrator should update the security lists and NSGs with the required ports, then complete the Data Guard association.
+
+Use the following command to destroy the deployment:
+
+```bash
+terraform destroy
+```
