EU Sovereign ServiceNow AI: Data Residency in the AWS Region of Your Choice

Why EU Sovereignty Has Become a Procurement Gate

For any EU-headquartered organisation buying AI tooling in 2026, data residency is no longer an architecture preference. It is a procurement gate. The combination of GDPR enforcement, sector-specific guidance from regulators like BaFin and the DPC, and the cumulative effect of the Schrems II ruling has made it standard to require that personal data be both stored and processed inside the EU.

ServiceNow development data is not innocuous. Even when developers think they are working with anonymised structures, the reality is that ticket bodies, knowledge articles, CMDB exports, user records, and audit logs routinely contain personal data within the meaning of Article 4(1) GDPR. Anything fed into an AI development assistant inherits that classification.

SnowCoder addresses this in two ways: through baseline GDPR compliance for every tier, and through pinned data residency in the AWS region of your choice (including EU regions) on Enterprise and Enterprise+ plans.

What "EU Sovereign" Means on Enterprise and Enterprise+

The Enterprise and Enterprise+ tiers pin the entire SnowCoder data path to a single AWS region of your choice. That includes:

• Storage of conversation history, Yeti Drive files, and audit logs in in-region S3 and RDS
• Inference traffic routed through in-region inference endpoints, never crossing region boundaries
• Operational logs and observability streams confined to the same region
• Backup and disaster recovery to a secondary AWS region within the EU, never outside
• Per-tenant isolation guarantees that survive even at the storage-key level, with per-record salts

In plain terms, no data your organisation puts into Yeti AI Chat, Yeti Drive, Yeti Build Agent, or Instance Audit ever leaves your chosen AWS region on Enterprise plans. Any region AWS offers is on the table - EU, UK, US, APAC, Middle East, or Africa. The choice is yours and is recorded in the DPA at contract.

The GDPR Posture Behind the Region Pin

Region pinning is necessary but not sufficient. GDPR compliance also requires the right contractual scaffolding and the right operational controls. SnowCoder ships:

• A Data Processing Agreement (DPA) executed at contract signature, naming SnowCoder as processor and the customer as controller
• Standard Contractual Clauses where applicable, with sub-processor disclosures kept up to date
• Per-tenant data deletion procedures aligned to Article 17 (right to erasure), with documented turnaround
• Subject Access Request support workflows aligned to Article 15
• Breach notification procedures aligned to the 72-hour clock under Article 33

The DPA is reviewed annually and re-issued on material change. Customers on Enterprise and Enterprise+ also receive a region-specific schedule that confirms the residency commitment in writing for the procurement file.

Mapping Residency to Specific Controls

The most common procurement question is "how do I evidence residency to my internal audit?" Below is the control mapping SnowCoder customers cite in their evidence pack.

Control Domain          | SnowCoder Control          | Evidence
------------------------+----------------------------+------------------
Data Location (storage) | AWS S3 + RDS, single region| Region tag in
                        | with bucket policies that  | bucket policy
                        | deny cross-region copy     | (DPA Annex B)
------------------------+----------------------------+------------------
Data Location (compute) | Inference endpoints        | Endpoint ARN
                        | scoped to chosen region only| in DPA Annex B
------------------------+----------------------------+------------------
Encryption at rest      | AES-256-GCM with per-      | KMS key policy
                        | record salt + PBKDF2       | scoped to region
                        | (100k iterations)          |
------------------------+----------------------------+------------------
Encryption in transit   | TLS 1.3 only               | TLS config in
                        |                            | ALB listener
------------------------+----------------------------+------------------
Authentication          | OAuth 2.1 + PKCE,          | Auth provider
                        | refresh-token rotation,    | logs, retained
                        | replay-attack detection    | in chosen region
------------------------+----------------------------+------------------
Tenant isolation        | Per-tenant encryption      | Tenant key
                        | keys, per-record salt      | inventory
------------------------+----------------------------+------------------
Backup residency        | Cross-region backup to     | Backup config
                        | second EU region only      | export
------------------------+----------------------------+------------------
Sub-processors          | Disclosed list, all EU     | DPA Annex C

This table is intentionally specific. It maps to the actual artifacts a Data Protection Officer needs to attach to a Record of Processing Activity, not to vague marketing language.

Where AI Models Fit Into the Residency Story

The trickiest part of any AI residency commitment is the model layer. Many AI tools advertise EU storage but then send inference requests to US-based foundation models. That is not residency. That is residency theatre.

SnowCoder on Enterprise and Enterprise+ routes all inference through models hosted inside your chosen AWS region. The 100,000+ vector ServiceNow knowledge base and the 17,000+ code examples that underpin retrieval-augmented generation are also stored in-region. Both the vector index and the embedding endpoint live inside the chosen region boundary.

The practical effect: a prompt about a sensitive HR Service Delivery flow never touches a US inference endpoint, never crosses an Atlantic fibre, and never appears in a US-region observability log.

Residency Versus Sovereignty: A Word on Vocabulary

Residency and sovereignty get used interchangeably in vendor marketing. They are not the same thing. Residency is a location commitment. Sovereignty layers a jurisdictional commitment on top: that no entity outside the data's jurisdiction can compel disclosure.

SnowCoder Enterprise and Enterprise+ offer full residency in any AWS region you choose, including EU regions. For organisations that need to assess sovereignty risk more deeply, the DPA includes:

• A government access request procedure with notification commitments where lawfully permitted
• A list of jurisdictions in which SnowCoder operates legal entities
• The current sub-processor list, scoped to EU entities only for Enterprise and Enterprise+ customers when an EU region is selected

Customers in highly regulated sectors are encouraged to walk through these documents in a working session with the SnowCoder team before signature. Talk to Sales for the kick-off.

How AWS-Region Residency Sits in the Tier Structure

SnowCoder ships on three commercial tiers:

• Standard: GDPR-compliant baseline, DPA on request, default multi-region storage
• Enterprise: Adds SAML SSO, advanced audit, dedicated success engineering
• Enterprise+: Adds dedicated CSM, 24/7 SLA, pentest report access under NDA, and the highest level of contractual and operational commitments. The AWS-region-of-choice data residency option is included on this tier and is also available on Enterprise

Full feature comparisons sit on the pricing page. The Enterprise+ residency commitment is in addition to the four commercial safeguards documented on the enterprise security page: per-tenant isolation, two clearly separated lanes for humans and agents, destructive-change confirmation, and a token budget as a hard stop.
