Microsoft has decided to shut down its Azure-based blockchain-as-a-service platform and is asking users to migrate their data to an alternative of their choice.

According to a blog post on Monday, the software giant has been quietly informing customers about the best way to jump ship before September 10. Support for new implementations or member creations has also been discontinued.

No reason has been given for the decision and Microsoft did not respond to CoinDesk’s attempt to contact it by phone.

Instead, it has been recommended to use the Quorum Blockchain Service from ConsenSys (which it acquired from the developer, JPMorgan), an Ethereum-focused blockchain company based in Brooklyn, New York.

Starting in 2015, Azure Blockchain was once designed as a type of “sandbox” that allowed partners to interact with different blockchain technologies and services, from smart contracts to tax reporting.
