Google API 用の Private Service Connect エンドポイントを使用するゲート付き上り（内向き）パターンで説明されている設計オプションも、このパターンに適用できます。具体的には、Cloud Storage、BigQuery、その他の Google Service API へのアクセスを提供します。このアプローチでは、VPN、Cloud Interconnect、Cross-Cloud Interconnect などのハイブリッド ネットワーク接続とマルチクラウド ネットワーク接続を介したプライベート IP アドレス指定が必要です。
ベスト プラクティス
Cloud Storage バケットと Pub/Sub トピックへのアクセスを制限します。
必要に応じて、 Google Cloud
ソリューション スイートなどのクラウド ファーストの統合データ移動ソリューションを使用してください。これらのソリューションは、ユースケースのニーズを満たすために、データを効率的に移動、統合、変換するように設計されています。
API ゲートウェイ、ロードバランサ、または仮想ネットワーク アプライアンスを使用して、VM インスタンスでホストされている一般公開されたデータ分析ワークロードと通信します。セキュリティを強化し、これらのインスタンスにインターネットから直接アクセスできないようにするには、次のいずれかの通信方法を使用します。

This pattern applies primarily to\nsetups that follow the\n[*analytics hybrid multicloud* architecture pattern](/architecture/hybrid-multicloud-patterns#analytics-hybrid-multicloud-patterns),\nwhere:\n\n- Workloads that are running in a private computing environment or in another cloud upload data to shared storage locations. Depending on use cases, uploads might happen in bulk or in smaller increments.\n- Google Cloud-hosted workloads or other Google services (data analytics and artificial intelligence services, for example) consume data from the shared storage locations and process it in a streaming or batch fashion.\n\nArchitecture\n------------\n\nThe following diagram shows a reference architecture for the handover\npattern.\n\nThe preceding architecture diagram shows the following workflows:\n\n- On the Google Cloud side, you deploy workloads into an application VPC. These workloads can include data processing, analytics, and analytics-related frontend applications.\n- To securely expose frontend applications to users, you can use Cloud Load Balancing or API Gateway.\n- A set of Cloud Storage buckets or Pub/Sub queues uploads data from the private computing environment and makes it available for further processing by workloads deployed in Google Cloud. Using Identity and Access Management (IAM) policies, you can restrict access to trusted workloads.\n- Use [VPC Service Controls](/vpc-service-controls) to restrict access to services and to minimize unwarranted data exfiltration risks from Google Cloud services.\n- In this architecture, communication with Cloud Storage buckets, or Pub/Sub, is conducted over public networks, or through private connectivity using VPN, Cloud Interconnect, or Cross-Cloud Interconnect. Typically, the decision on how to connect depends on several aspects, such as the following:\n - Expected traffic volume\n - Whether it's a temporary or permanent setup\n - Security and compliance requirements\n\nVariation\n---------\n\nThe design options outlined in the\n[*gated ingress* pattern](/architecture/hybrid-multicloud-secure-networking-patterns/gated-ingress),\nwhich uses Private Service Connect endpoints for Google APIs, can also\nbe applied to this pattern.\nSpecifically, it provides access to Cloud Storage, BigQuery,\nand other Google Service APIs. This approach requires private IP addressing over\na hybrid and multicloud network connection such as VPN, Cloud Interconnect\nand Cross-Cloud Interconnect.\n\nBest practices\n--------------\n\n- Lock down access to Cloud Storage buckets and Pub/Sub topics.\n- When applicable, use cloud-first, integrated data movement solutions like the Google Cloud [suite of solutions](/data-movement). To meet your use case needs, these solutions are designed to efficiently move, integrate, and transform data.\n- Assess the different factors that influence the data transfer options,\n such as cost, expected transfer time, and security. For more\n information, see\n [Evaluating your transfer options](/architecture/migration-to-google-cloud-transferring-your-large-datasets#step_3_evaluating_your_transfer_options).\n\n- To minimize latency and prevent high-volume data transfer and movement over\n the public internet, consider using Cloud Interconnect or\n Cross-Cloud Interconnect, including accessing\n Private Service Connect endpoints within your Virtual Private Cloud for\n Google APIs.\n\n- To protect Google Cloud services in your projects and to mitigate\n the risk of data exfiltration, use VPC Service Controls. These service\n controls can specify service perimeters at the project or VPC network level.\n\n - You can [extend service perimeters](/vpc-service-controls/docs/overview#hybrid_access) to a hybrid environment over an authorized VPN or Cloud Interconnect. For more information about the benefits of service perimeters, see [Overview of VPC Service Controls](/vpc-service-controls/docs/overview).\n- Communicate with publicly published data analytics workloads that are\n hosted on VM instances through an API gateway, a load balancer, or a\n virtual network appliance. Use one of these communication methods for added\n security and to avoid making these instances directly reachable from the\n internet.\n\n- If internet access is required,\n [Cloud NAT](/nat/docs)\n can be used in the same VPC to handle outbound traffic from the instances\n to the public internet.\n\n- Review the\n [general best practices](/architecture/hybrid-multicloud-secure-networking-patterns/general-best-practices)\n for hybrid and multicloud networking topologies."]]
