Platform-as-a-service (PaaS) is a kind of cloud computing service in which, rather than having to build and maintain their own infrastructure, a client is able to develop, run, and manage applications on a platform that is provided by a third-party provider. The provider hosts both software and hardware, freeing the client from having to install and handle them in-house.
Cloud Foundry builds the runtime environment directly without requiring dependency management from the user.
IBM is the only vendor to offer integration with blockchain for smart contract development.
