Method and proof.
How an island is built with a declarative and reproducible method, and how it is verified to work before it is handed over.
Infrastructure built by a method.
Every island is built with a declarative method: the infrastructure is described in full, and that description is what produces the system. The final state does not depend on manual steps or on anyone's memory. The same description always produces the same island, so building it, repairing it and rebuilding it are the same operation.
An immutable base.
The base system is read-only. It is not modified during operation, neither by an error nor by an unauthorized access, and its state can be verified at any time. If an island is compromised, the response is to rebuild it from its description, with the guarantee that it returns to a known, clean state.
Everything described and versioned.
All the infrastructure is described and versioned. Nothing is configured by hand. Every change is recorded with date and author, so the way an island is built is verifiable at any time, without depending on anyone's memory.
The recovery test.
Before an island is handed over, a real recovery test is run. The island is rebuilt in full from its description and its data is restored. It is then confirmed that the data has returned intact and that the system is operational. The time the recovery takes is measured and documented. Recovery is verified and recorded before delivery, not assumed.
One infrastructure per client.
Each client has its own island. There is no co-tenancy of servers, storage or network with any other client. The client team accesses its applications with a single identity and two-factor authentication, under a Zero Trust model: no application is reachable without prior validation and no port is open to the internet.
How it works.
The method describes how the island is built and tested. The how it works page describes the full path of the service: the phases, the available tiers and what gets delivered.
