+# OCI multicloud landing zone for Azure
+
+Oracle Cloud Infrastructure (OCI) partnered with Microsoft Azure to develop and distribute HashiCorp Terraform/OpenTofu modules that streamline the provisioning process.
+
+When you use both OCI Multicloud Landing Zone for Azure (OCI LZ) and Microsoft Verified Modules (MVM), multiple templates empower Oracle Database@Azure. These Terraform/OpenTofu modules use four (4) terraform providers, AzureRM, AzureAD, AzAPI, and OCI, covering IAM, networking, and database layer resources. Apply these reference implementations for a quick start deployment, or customize them for a more complex topology fit to your needs.
+
+The following diagram illustrates where Terraform or OpenTofu can be introduced to streamline the identity, access, networking, and provisioning processes within Oracle Database@Azure.

+
+## Prerequisites
+1. Complete, at a minimum, steps 1-2 of the [Onboarding with Oracle Database@Azure](https://docs.oracle.com/iaas/Content/multicloud/oaaonboard.htm).
+1. Have a Terraform/OpenTofu, OCI CLI, Azure CLI, and python (minimum 3.4) environment. For more information, see the [Oracle Multicloud Landing Zone for Azure README](https://github.com/oracle-quickstart/terraform-oci-multicloud-azure?tab=readme-ov-file#prerequisites).
+
+### Dependencies
+The [Oracle Multicloud Landing Zone for Azure](https://github.com/oracle-quickstart/terraform-oci-multicloud-azure) modules and templates use multiple Terraform providers.
