Amazon Web Services (AWS), the e-commerce giant's cloud computing arm, has launched its Managed Blockchain service for wider use among enterprise clients.

AT&T, Nestle, Accenture and others are already using the service, AWS announced Tuesday.

Initially revealed last November, Amazon Managed Blockchain is said to allow clients to create and manage blockchain networks more easily and economically using open-source frameworks like Hyperledger Fabric. Until now, the service was previously available only in "preview," meaning interested firms could sign up for approval to use the service.

With that stage now over, the service is available for general production use, said AWS’ chief evangelist, Jeff Barr, in a separate blog post, adding: 

Support for the ethereum network is still in the works and is expected to be made available later this year, AWS said.

It's worth noting that the service is currently available only in AWS' U.S. East (Northern Virginia) region, although more areas are expected to be opened up in the "coming year."

Nestle Oceania’s digital technology manager, Armin Nehzat, said:

Securities and derivatives trading platform Singapore Exchange (SGX), on the other hand, is working with AWS to move its existing work on Hyperledger Fabric to Amazon Managed Blockchain, said its head of blockchain technology, Andrew Koay.

Accenture, non-profit foundation MOBI (Mobility Open Blockchain Initiative) and enterprise asset management company TrackX are also using the service, according to AWS.
