# Google Distributed Cloud GDC > Source-anchored research for Google Distributed Cloud GDC. Run status: COMPLETED. Parent: [MongoDB Atlas on GCP](https://llms-explorer.com/tree/mongodb-atlas-on-gcp/) · 3 facets · 16 facts · page: https://llms-explorer.com/tree/google-distributed-cloud-gdc/ ## How it works - Disconnected operation still requires a software supply process: Google documents downloading the distribution externally, transferring it on portable storage and checking its integrity inside the isolated environment. (low confidence) (verified as of 2026-10-20) — [source](https://docs.cloud.google.com/distributed-cloud/hosted/docs/latest/gdcag/overview) - Disconnected operation still requires a software import process. Google documents downloading distributions outside the isolated environment and transferring them on portable storage; its security documentation assigns validation and import of signed update binaries to the infrastructure operator. (high confidence) (verified as of 2026-10-20) — [source](https://docs.cloud.google.com/distributed-cloud/hosted/docs/latest/gdcag/overview) ## Comparisons and alternatives - GDC air-gapped hosts infrastructure and services on premises without requiring connectivity to Google Cloud or the public internet for infrastructure management. This differs from the connected GDC offering. (high confidence) (verified as of 2026-10-20) — [source](https://docs.cloud.google.com/distributed-cloud/hosted/docs/latest/gdcag/overview) - MongoDB identifies Enterprise Advanced as the MongoDB product available on GDC air-gapped; its earlier announcement calls the environment GDC Hosted. Treat this as a self-managed MongoDB deployment choice, rather than evidence of an Atlas service running inside GDC. (high confidence) (verified as of 2025-07-16) — [source](https://www.mongodb.com/docs/kubernetes/current/gdc-hosted.md) - The GDC air-gapped appliance is a distinct tactical-edge platform. Google documents a single-tenant model and a single cluster across three bare-metal nodes, with a feature set that differs from data-center GDC air-gapped. (low confidence) (verified as of 2026-10-20) — [source](https://docs.cloud.google.com/distributed-cloud/hosted/docs/latest/appliance/overview) ## Facts and statements - MongoDB documents installation of Kubernetes Operator from the built-in GDC air-gapped application marketplace; it manages the namespace in which it is installed. (low confidence) (verified as of 2026-10-14) — [source](https://www.mongodb.com/docs/kubernetes/current/gdc-hosted.md) - MongoDB requires appropriate Enterprise Advanced licenses for use on GDC air-gapped and directs licensing questions to user@example.test. (high confidence) (verified as of 2026-10-14) — [source](https://www.mongodb.com/docs/kubernetes/current/gdc-hosted.md) - The MongoDB announcement updated July 16, 2025 describes the Enterprise Kubernetes Operator working with self-hosted Ops Manager to deploy, monitor, back up, and scale MongoDB. That historical product naming should be checked against current operator documentation before implementation. (low confidence) (verified as of 2025-07-16) — [source](https://www.mongodb.com/company/blog/product-release-announcements/mongodb-enterprise-advanced-google-distributed-cloud-hosted) - Google distinguishes GDC connected from GDC air-gapped; connectivity and isolation properties of one variant should not be generalized to the other. (low confidence) — [source](https://docs.cloud.google.com/distributed-cloud/hosted/docs/latest/gdcag/overview) - Google publishes Golang API definitions for GDC air-gapped in google-distributed-cloud-apis. Its README describes an auto-generated read-only mirror with best-effort alignment to public API documentation. (low confidence) (verified as of 2026-10-23) — [source](https://github.com/GoogleCloudPlatform/google-distributed-cloud-apis) - WWT, AppFaktors and Google’s March 2025 architecture guidance identifies Infrastructure Operator, Platform Administrator and Application Operator roles, plus separation of duties, continuous staffing and multi-party change approvals, as GDC operational considerations. (low confidence) (verified as of 2025-03-18) — [source](https://www.wwt.com/article/app-modernization-framework-transforming-on-prem-legacy-systems-with-gdc) - Computer Weekly’s May 6, 2026 original analysis criticizes Google for answering general cloud sovereignty questions using GDC air-gapped assurances. This is independent editorial scrutiny of claim scope, not an independent test of MongoDB or GDC security. (low confidence) (verified as of 2026-05-06) — [source](https://www.computerweekly.com/feature/Is-cloud-data-sovereignty-all-just-a-case-of-Trust-me-bro) - Gartner published an October 2025 technical assessment of GDC air-gapped whose public outline includes limits of an air gap and operational independence; the public abstract does not expose the underlying findings. (low confidence) (verified as of 2025-10-23) — [source](https://www.gartner.com/en/documents/7096630) - MongoDB directs users to install its Kubernetes Operator through the built-in GDC air-gapped application marketplace. The integration uses Kubernetes to manage MongoDB deployments within the isolated environment. (high confidence) (verified as of 2025-07-16) — [source](https://www.mongodb.com/docs/kubernetes/current/gdc-hosted.md) - Google documents that the infrastructure operator may be Google, a contracted third party, or the customer, depending on sovereignty restrictions. Air-gapped deployment therefore does not by itself establish who performs infrastructure operations. (low confidence) (verified as of 2026-10-20) — [source](https://docs.cloud.google.com/distributed-cloud/hosted/docs/latest/gdcag/security) - Do not infer MongoDB appliance compatibility from data-center GDC air-gapped availability: MongoDB documents the latter integration, while Google separately documents appliance architecture and feature differences. The reviewed sources do not establish an appliance-specific MongoDB support matrix. (medium confidence) — [source](https://www.mongodb.com/docs/kubernetes/current/gdc-hosted.md)
