Manufacturing and defence: operational sovereignty, export control and continuity.
In manufacturing and defence, the question is not only where the data is hosted. It is to understand how the organisation can keep working, collaborating and deciding when access to a supplier, a technology or certain data is restricted.

Three defining requirements shape this field.
Sovereignty is not just about where data is located. It includes the ability to operate the systems, recover the information, change supplier, sustain operations and keep the skills needed to act without excessive dependence.
In an international environment, not all information can be accessible to every employee, partner or subcontractor. Export control, confidentiality and nationality rules can require fine-grained partitioning, access restrictions and precise traceability of exchanges.
Incident, change, access, approval and archiving processes have to stay understandable and auditable. The evidence has to be produced at the moment of the action, not reconstructed afterwards.

The Atlassian Data Center exit has a timetable.
The official Atlassian timetable sets three deadlines for the Data Center products concerned.
An industrial environment kept on premise for good reasons therefore has a decision to work through, with time on its side. We scope that decision in the assessment Controlled Data Center Exit, in 6 to 10 weeks: the sequence is set out on Atlassian Cloud migration.
What we put in place
| Requirement | What it means in practice | What BleuLemon puts in place |
|---|---|---|
| Operational sovereignty | Continuing to operate without depending on a single supplier | Reversibility architecture, export of data and configurations, documentation, alternative hosting, tested exit scenarios. |
| Export control | Restricting access according to the applicable rules | Separate scopes, dedicated groups and permissions, access workflows, logging, partitioned test environments. |
| Sensitive data | Preventing uncontrolled circulation | Classification, anonymisation or masking for testing, sharing rules, periodic review of permissions. |
| Traceability | Being able to reconstruct a decision or an action | Timestamped workflows, approvals, a usable history, archiving of closed projects outside the active instance. |
| Supplier continuity | Preparing a real exit, not a theoretical one | Recovery tests, retention of usable formats, contractual and operational documentation of reversibility. |
The real test of sovereignty is not going in with a supplier. It is the ability to leave without losing control of your operations.
Archiving has its own page: Jira archiving before migration, with Aquarius, our extraction solution that can be consulted outside Jira.
Our references in this industry.
Safran is among BleuLemon's references. The scope of the engagement remains covered by a confidentiality agreement: we present the arrangement and the indicators in a meeting, never beyond what the client has authorised.

Frequently asked questions
A question that finds no answer here is dealt with in a thirty-minute conversation, about your actual context rather than a general case.
Talk to an expertWhat does "operational sovereignty" actually mean?
The ability to keep working if a supplier becomes unavailable, if an offer changes or if a legal or commercial constraint limits its use. That requires recoverable data, documented configurations, in-house skills and a realistic exit path.
How do you take export control into account?
By translating the applicable rules into permissions, scopes, access workflows and logging. The setup depends on the client's context: countries, data, programmes, subcontractors and categories of authorised people.
Do you necessarily have to stay on premise?
No. The point is not to favour one architecture on principle, but to choose a target that fits the requirements for confidentiality, continuity, access and reversibility.
How do you prove the traceability of a change?
Each change can involve a requester, an impact assessment, approvals, an execution window and an outcome. The history stays available and can be archived in a usable format for closed projects.
