Throughout the development of our microservices, we heavily leveraged dependency injection. As part of a .NET web application's startup process, you register the individual types that should be part of the inversion of control (IoC) container. Individual classes inject their dependencies as interfaces in their constructor arguments. This allows different concrete implementations to be used depending on the context. For example, an interface for a telemetry client may be utilized throughout the codebase. The concrete implementation in the live-service sends actual telemetry data to a remote endpoint. A mocked implementation is used in unit tests to validate the correct event would be sent at the appropriate time.
There is no one single plan for how to abandon ship, since everything will depend on, well, everything. But something has to happen, because a giant piece of space trash will be headed toward Earth—albeit very, very slowly, and with the oversight of the world’s top space engineers and scientists. But still, a worrisome situation. Ideally, the US Deorbit Vehicle, our Dragon, will be ready to shepherd the ISS to the atmosphere, over a safe zone in the Pacific Ocean.
