At the Ethereum Developer Conference on November 9, Microsoft announced that it would offer blockchain building blocks as part of its Azure cloud hosting platform; the Ethereum Blockchain as a Service (EBaaS) offering allows developers to quickly launch an Ethereum environment which includes code building blocks for SmartContracts and a semi-private testing environment with a blockchain which then can be migrated to the public Ethereum environment; the offering is in partnership with development house ConsenSys.
