TL;DR
Direct answer: Private cloud for an analytics agent is isolation with a managed update and model path. An air gap is a physical cut: no path, media only. Do not call a locked VPC an air gap. Choose private cloud when you need isolation and still want patches. Choose air-gap when exits must be physical.
Isolation, credentials, resume, and quota exist in both forms. Desktop is neither. This page is a selection, not a plant diagram.
What you'll learn:
- A definition of private cloud that a reviewer can quote
- Three scoring axes: connectivity, updates, model exit
- Choose-A / choose-B against air-gap
- Steps to refuse a mislabel
- An illustrative 8 / 42 / 88 desk
- Failure modes: VPC-as-air-gap, hidden model, unpatchable ops
The hub on premise AI lists both forms. This cluster is the selection.
What private cloud means for an analytics agent
Key Definition: Private cloud for analytics agents is a VPC or equivalent network boundary you operate, where the long task, credentials, and artifacts stay isolated, while an allowed channel still carries updates and, if you choose, an in-boundary model path. It is not an air gap and not a warehouse purchase.
Public AI overviews such as Google Cloud’s page on artificial intelligence treat models as services you place. That placement is the agent runtime in a network you control. The model may sit in the same VPC. It may not. Write the line.
A data warehouse can already live in a VPC. This page is not “buy another store.” It is the agent next to sources you already have. PostgreSQL documentation is a reminder that the database can stay yours. The agent still needs isolation, resume, and quota around it.
Enterprise data security solutions already sell VPC patterns. Data security and compliance writes the policy. This form is where that policy allows a channel. If the policy forbids every channel, you want private GPT, not this page.
Embed an AI data analyst can call the same runtime whether the host is SaaS or private cloud. The task shape does not change. The network does.
Selection framework: connectivity, updates, model exit
Fill three cells. This form is the row where connectivity is constrained but not zero.
| Requirement | SaaS proof | Private cloud | Air-gap |
|---|---|---|---|
| Connectivity | Vendor path | Your VPC / plant net | None at runtime |
| Updates | Vendor | Managed channel you allow | Signed media |
| Model exit | Often vendor API | In-boundary or allowed API | Preloaded weights |
| Ops | Vendor | Your SRE + vendor channel | Room + media owners |
A path is still a path
If a packet can leave with a ticket, you have private cloud, not an air gap. Say it. Reviewers can live with a named path. They cannot live with a synonym.
Managed updates are the point
The form exists because plants still need patches. If you refuse the channel and also refuse media, you have an unpatchable island. That is not a form. That is neglect.
Private cloud vs air-gap
| Need | Choose private cloud | Choose air-gap |
|---|---|---|
| Isolation from the public internet | Yes | Yes |
| Vendor or internal patch channel | Yes | No |
| Physical exit only | No | Yes |
| Remote ops | Often | Rare |
| Private AI three exits already mapped | Then pick this or that | Then pick this or that |
Choose tenant cloud if you still want a channel
Most analytics teams should land here. The VPC runtime keeps the job isolated and lets you take a model or runtime update without walking a disk. If that is acceptable, do not buy air-gap theater.
Choose air-gap if a reviewer fails any packet
When the written rule is physical, private GPT is the preload list. A connected VPC is the wrong PO. Do not stretch the subnet into that word.
Landscape of isolation products
Engine docs such as Apache Spark documentation describe compute you can place in a VPC. The isolated network still needs the agent runtime around that compute. A Spark job without a task id is not the decision job.
| Product | Isolation story | Agent test |
|---|---|---|
| Warehouse VPC | Store is private | Does the agent key leave? |
| Private cloud runtime | Task is private | Resume and quota exist |
| Air-gap pack | No path | Media list complete |
| Desktop | Client is local | Not this selection |
API security still applies inside a VPC. The OWASP API Security Project is the independent map for object-level authz on the task API. Isolation is not a reason to skip it.
Draw two diagrams, not one. Diagram A is the warehouse and its peers. Diagram B is the agent: queue, workers, artifact store, console, model endpoint, log sink. If B is missing, you selected a store. Reviewers who only see A will approve a network and then discover prompts leaving through an undocumented API. Keep B on one page. Date it. When the model endpoint moves, redraw B the same week.
Write the allowed egress as a short table: destination, purpose, owner, ticket path. “None except patch and DNS” is a valid row. “None except the model we forgot” is how selections fail. If the table is empty because someone said “it is isolated,” you do not have a selection. You have a slogan. Bring SRE and security to the same review so the channel and the deny list are the same document.
Fund the patch path in the same quarter as the install. A VPC that cannot take a runtime update without a six-month change board will rot. Isolation without a cadence is how CVEs accumulate behind a proud subnet. Name the cadence on the PO. If you cannot name it, you are not ready to leave the SaaS proof.
A warehouse VPC is not the agent VPC
Teams draw one cloud. The agent network is a second drawing: queue, store, console, model. If you only drew the warehouse, you have not selected a form. You have selected a store.
BI in a VPC is not the decision job
A business intelligence tool can sit in the same network. Pixels are not plan, SQL, and files. The agent form for this pillar is the runtime, not a dashboard lift-and-shift.
How to score VPC isolation vs a true air gap
- Input: The SaaS-proven task. Accept: Trail exists. Reject: No job to move.
- Input: A one-page connectivity diagram. Accept: Every egress named. Reject: “It is private.”
- Input: Update owner and cadence. Accept: Channel or media, not both undefined. Reject: “We will see.”
- Input: Model exit. Accept: In-VPC endpoint or weights. Reject: Unknown public API.
- Input: Kill-and-resume in the VPC. Accept: Same id. Reject: Chat restart.
- Input: The word you will write on the PO. Accept: “Private cloud” or “air-gap,” not both. Reject: Marketing synonym.
Desk sample: three requirements, two forms (illustrative)
Illustrative only. Not a customer result. Not an unpublished SLA.
A risk committee scores an opex question already proven on 8 entities (illustrative 42k rows, 88-edge pack). They need isolation, monthly patches, and no public model.
| Requirement | Private cloud fit | Air-gap fit |
|---|---|---|
| Isolation | High | High |
| Monthly patches | High (channel) | High only if media SOP exists |
| No public model | High if endpoint is in-VPC | High if weights preloaded |
| Remote SRE | High | Low |
| Ops cost (illustrative) | Lower | Higher |
Figure. Illustrative desk composite, not a customer result.
In this composite the private cloud form wins because patches are required and a channel is allowed. Air-gap would win only if the committee forbade the channel. Private cloud is the channel-allowed form of the same job, not a new analysis method.
Record who owns the egress table and who owns the patch cadence. Those two names should appear in the same review packet as the SaaS-proven task id. If either name is missing, postpone the move. Isolation without owners is how a subnet ages into an unpatched island. A quarterly reopen of the egress table is enough. Do not invent a second policy encyclopedia.
Scorecard: tenant cloud fit vs air-gap fit
| Signal | Pick private cloud | Pick air-gap | Pick neither yet |
|---|---|---|---|
| Job not proven | — | — | Stay on SaaS proof |
| Channel allowed | Yes | No | — |
| Any packet fails the policy | No | Yes | — |
| Desktop-only request | Different page | Different page | — |
| Replace the ERP | Refuse | Refuse | Refuse |
Choose A when isolation plus updates is the real need. Choose B when the cut is physical. Choose neither if the trail is still missing.
Evidence boundary
This page (private-cloud) is a first-party desk method on VPC vs air-gap selection, not a customer case and not an independent audit. The figures in the chart are an illustrative composite. They do not measure your warehouse, your model, or a published SLA.
A qualifying external review would need owner approval, an authorized read-only source, versions of the named objects, and a written accept/reject on the trail. Until that exists, do not cite this page as third-party recognition, a certification, or a media mention.
Record the freeze date, the reviewer name, and the file names you actually opened. If a later owner only reran a lint check, they should say so. Internal review is not independent validation.
Do not prove a negative privilege by writing to a production system. Read-only is the control. If a vendor offers write-back as “analysis,” treat that offer as a different product and a different risk.
Failure modes
Calling a locked VPC an air gap
The most common miss. Private cloud can be the right buy. The word air-gap is then a lie. Write VPC. Sleep better.
A model path you forgot to draw
The warehouse stays in the VPC. The prompt leaves. Private cloud failed the model line. Draw the endpoint or you have private AI theater.
Ops that cannot patch
You refused the vendor channel and never funded media. Private cloud without updates becomes an island of CVEs. Isolation does not excuse an unpatched runtime.
The hub on premise AI holds the ladder. Private GPT is the air-gap preload. Private AI is the three-exit map you should complete before this selection.
Choose VPC isolation or a true air gap
Score connectivity, update channel, and model exit. Do not call a locked VPC an air gap. This check uses only sources you authorize.

Frequently Asked Questions
Is a locked VPC the same as an air gap?
Bottom line: No. Private cloud still has a path you allow. An air gap does not. Do not swap the words.
Should most teams buy air-gap instead of this?
Bottom line: No. Most teams need isolation plus patches. Private cloud is that pair. Air-gap is the physical subset.
Does this replace our warehouse?
Bottom line: No. The warehouse is a source. Private cloud hosts the agent. It is not an ERP replacement.
Can we skip the SaaS proof if we already have a VPC?
Bottom line: No. Prove the job first. Private cloud moves a trail. A network is not a trail.
Do resume and quota still exist in this?
Bottom line: Yes. Isolation, credentials, resume, and quota do not disappear because the subnet is yours.
Conclusion
Private cloud is isolation with a managed update and a named model path. Air-gap is a physical cut and a media list. They are not synonyms. Desktop is not this selection. Prove the isomorphic job, draw every egress, then write one word on the PO.
If you later use the workspace, open InfiniSynapse only with authorized, sanitized inputs. After that proof, Book a Demo if the form is private cloud or a true air gap.
