# Deploy Oracle Database@Google Cloud - Source: https://docs.oracle.com/en/solutions/deploy-oracle-database-at-google-cloud/index.html - Date: 2025-10 - Type: reference-architecture - Services: exacs, adb-d, google-cloud - Tags: database, multicloud, autonomous ## Summary (catalog) ExaCS and ADB-D on Database@Google Cloud. RAC for active-active HA, ASM for storage redundancy. Backups to OCI Object Storage via Autonomous Recovery Service. ## Architecture (fetched from source) Architecture This architecture shows a detailed topology for Oracle AI Database@Google Cloud : Description of the illustration google-detailed-arch.png google-detailed-arch-oracle.zip The architecture displays application resources within a VPC of a Google Cloud project, located in a single zone of a Google Cloud region. An application subnet in the VPC connects to Oracle AI Database@Google Cloud using the ODB network in the OCI child site, located in the same Google Cloud region. The client subnet of the Oracle Autonomous AI Database Serverless , the Oracle Exadata Database Service on Dedicated Infrastructure client subnet, and the backup subnets of Oracle Database Autonomous Recovery Service are defined in the ODB network . The VCN extends into the OCI region to enable connections to other resources within OCI. The OCI region hosts the following OCI services: OCI Vault , OCI Object Storage , and control plane. This architecture supports the following components: - Google Cloud region A Google Cloud region is a geographical area that contains data centers and infrastructure for hosting resources. Regions are made up of zones, which are isolated from each other within the region. - Google Virtual Private Cloud Google Virtual Private Cloud (VPC) provides networking functionality to Compute Engine virtual machine (VM) instances, Google Kubernetes Engine (GKE) containers, database services, and serverless workloads. VPC provides global, scalable, and flexible networking for your cloud-based service. - Google Cloud zone A zone in Google Cloud is a deployment area for resources within a region. Zones are isolated from each other within a region, and are treated as a single failure domain. - Google Cloud project A Google Cloud Project is required to use Google Workspace APIs and build Google Workspace add-ons or apps. A Cloud Project forms the basis for creating, enabling, and using all Google Cloud services, including managing APIs, enabling billing, adding and removing collaborators, and managing permissions. - ODB network The ODB network creates a metadata construct around the Google Virtual Private Cloud (VPC), serving as the foundation for all database provisioning. The ODB network enables support for Shared VPC by abstracting and centralizing network configuration - such as subnets, CIDR ranges, and routing. This allows network administrators to manage connectivity independently of database deployment workflows. - OCI region An OCI region is a localized geographic area that contains one or more data centers, hosting availability domains. Regions are independent of other regions, and vast distances can separate them (across countries or even continents). - OCI virtual cloud network and subnet A virtual cloud network (VCN) is a customizable, software-defined network that you set up in an OCI region. Like traditional data center networks, VCNs give you control over your network environment. A VCN can have multiple non-overlapping classless inter-domain routing (CIDR) blocks that you can change after you create the VCN. You can segment a VCN into subnets, which can be scoped to a region or to an availability domain. Each subnet consists of a contiguous range of addresses that don't overlap with the other subnets in the VCN. You can change the size of a subnet after creation. A subnet can be public or private. - Oracle Autonomous AI Database Serverless Oracle Autonomous AI Database Serverless is an Oracle Autonomous AI Database . You have a fully elastic database where Oracle autonomously operates all aspects of the database lifecycle from database placement to backup and updates. - Oracle Exadata Database Service on Dedicated Infrastructure Oracle Exadata Database Service on Dedicated Infrastructure enables you to leverage the power of Exadata in the cloud. Oracle Exadata Database Service delivers proven Oracle AI Database capabilities on purpose-built, optimized Oracle Exadata infrastructure in the public cloud. Built-in cloud automation, elastic resource scaling, security, and fast performance for all Oracle AI Database workloads helps you simplify management and reduce costs. - OCI Object Storage OCI Object Storage provides access to large amounts of structured and unstructured data of any content type, including database backups, analytic data, and rich content such as images and videos. You can safely and securely store data directly from applications or from within the cloud platform. You can scale storage without experiencing any degradation in performance or service reliability. - OCI Vault Oracle Cloud Infrastructure Vault enables you to create and centrally manage the encryption keys that protect your data and the secret credentials that you use to secure access to your resources in the cloud. The default key management is Oracle-managed keys. You can also use customer-managed keys which use OCI Vault . OCI Vault offers a rich set of REST APIs to manage vaults and keys. Recommendations Use the following recommendations as a starting point when deploying multicloud workloads. Your requirements might differ from the architecture described here. - High Availability Oracle Autonomous AI Database and Oracle Exadata Database Service provide high availability through several built-in features that ensure minimal downtime and data protection. It leverages Oracle Real Application Cluster (RAC) for active-active clustering, enabling database instances to run on multiple nodes, ensuring continuous availability even if one node fails. Additionally it offers Oracle Automatic Storage Management (ASM) with redundancy, fault tolerance, and fast recovery options, making it a robust platform for mission-critical workloads. - Backup Oracle Autonomous AI Database in Oracle AI Database@Google Cloud is automatically backed up to OCI Object Storage in the OCI region. Both the backup and restore processes are initiated through Oracle Autonomous AI Database . Autonomous AI Database also can have customer initiated backups through the Autonomous AI Database service. All recovery is done through Autonomous AI Database via console, command line, or API interfaces. Oracle Exadata Database Service has a choice of using Oracle Database Zero Data Loss Autonomous Recovery Service or OCI Object Storage for automatic database backups. Autonomous Recovery Service dramatically shortens backup windows by configuring database-optimized automatic backups and implements an incremental backup forever strategy. It reduces recovery time by using virtual full backups to immediately restore instead of having to apply multiple days of incremental backups in a traditional recovery. - Security Oracle Data Safe is an OCI cloud-native tool that enables you to achieve data privacy and data compliance for your Oracle databases. Oracle Data Safe empowers organizations to understand data sensitivity, evaluate data risks, mask sensitive data, implement and monitor security controls, assess user security, monitor user activity, and manage Oracle Database 23ai SQL Firewall—all in a single, unified console. These capabilities help to manage the day-to-day security and compliance requirements of Oracle databases. Considerations When deploying this architecture, consider the following information. - Tenancy The tenancy must support OCI identity domains. You can create an OCI tenancy when signing up. - Network Connectivity Plan your network connectivity in advance to define your network address space (CIDR) and topologies. Create the ODB network in the same Google Cloud project as the VPC to which you will connect. The CIDR blocks for any Google Cloud VPCs and OCI VCNs must not overlap. - Configuration Database subnet
