OPEN SOURCE
& DIGITAL SOVEREIGNTY
Leverage open-source technologies to achieve true digital sovereignty and control. Escape vendor lock-in, own your infrastructure, and maintain full autonomy over your data and systems.
SOVEREIGNTY CAPABILITIES
The work we do to take an organisation from vendor-captive to genuinely sovereign — across platforms, productivity tools, hosting, identity, and engineering capability.
Open-source platform engineering
Kubernetes, Proxmox, OpenStack, Postgres, Linux. Standards-based platforms that you can operate, audit, and migrate without paying tribute to a vendor.
Self-hosted SaaS alternatives
Mattermost instead of Slack. Nextcloud instead of Drive. GitLab instead of GitHub Enterprise. The same productivity, owned by you, hosted where you choose.
Sovereign hosting
Capacity on Tasmanian Cloud — sovereign infrastructure operated in lutruwita/Tasmania on Tasmanian-owned hardware. No foreign jurisdiction, no shared control plane.
Migration off proprietary stacks
Wave-based migration off AWS, Azure, GCP, or proprietary SaaS. Mapped dependencies, honest TCO, and rollback at every step. We move you out of lock-in, not just to a different vendor.
Identity and access on open standards
Keycloak, OIDC, SAML, SCIM. Standards-based SSO that integrates with whatever you already have — and keeps integrating when you swap one of the pieces out.
Engineering capability transfer
We bring your team along. The skills are portable, the tools are open, and the lock-in evaporates over time. Your engineers come out the other side more valuable, not less.
SOVEREIGNTY BY ARCHITECTURE
Sovereignty as a discipline
We've operated Tasmanian Cloud since day one. Sovereignty isn't a marketing claim — it's the architectural starting point for everything we build.
Open source, not 'open core'
We deploy genuine open-source platforms with permissive or copyleft licences — not 'open core' products with paywalled enterprise features that recreate the lock-in.
Migration without drama
We've migrated organisations off SaaS, off hyperscalers, and off proprietary on-prem. We know the edge cases, the cleanup work, and where the surprises usually live.
Tasmanian-owned
TWN Systems is owned and operated in lutruwita/Tasmania. The control plane stays in Australia. The engineers stay in Australia. The data stays where you put it.
SOVEREIGNTY QUESTIONS
What is digital sovereignty?
Digital sovereignty means an organisation has meaningful control over its digital systems — where the data lives, who can access it, what jurisdictions apply, and the ability to change vendors without prohibitive cost. It's the opposite of vendor lock-in.
Why open source for sovereignty?
Open source removes the single-vendor dependency that drives lock-in. The code is auditable, the contracts are non-coercive, and migration is technically possible because the tooling and skills are portable. Proprietary equivalents make sovereignty structurally hard.
Do we have to leave AWS/Azure/GCP entirely?
No. We don't argue for full repatriation. Genuinely cloud-native or bursty workloads stay on hyperscalers. Predictable, sovereign-relevant, or sensitive workloads move to sovereign capacity. Hybrid is the realistic destination for most organisations.
How long does a sovereignty engagement take?
We start with a discovery and reference architecture (4-10 weeks combined). Pilot migrations run 6-12 weeks. Full estate migrations are typically 3-12 months in waves. Steady-state is ongoing — sovereignty is a posture, not a project.
