Ubicloud
Open source alternative to AWS. Elastic compute, block storage
...The system is designed to run workloads in a multi-tenant fashion, providing container and VM orchestration, security isolation, and billing mechanisms. It also addresses portability, encouraging workloads that can move seamlessly between providers in the network. Ultimately, Ubicloud envisions reducing vendor lock-in and creating a more democratic cloud marketplace by combining open-source infrastructure management with federated governance.
