1. Create your local micro-cloud on-premise, say with OpenStack and Kubernetes, so that you can start and scale up quickly
2. Use open data and open standards and avoid any layered product that is offered by the cloud provider, it will lock you in.
3. Automate deployments as much as you can, so that is reproducible and can be run on-premise

The idea I’m currently advocating is to apply the Raiffeisen model to IT to foster a complementary alternative to public clouds and big outsourcers so that heterogeneous enterprises in a local territory can team up to create a small micro-cloud and save.
