Amazon Web Services (AWS) is coming around to the blockchain craze after all.

The company still isn’t planning its own service based on blockchain — “We don't build technology because we think the technology is cool,” AWS CEO Andy Jassy told reporters at the annual re:Invent conference last month, after being asked about AWS' blockchain plans.

But the company is launching a portal to support its customers’ integration of blockchain services built on AWS.

“AWS provides the broadest and deepest capabilities with the largest global infrastructure for building end-to-end blockchain solutions,” Ale Flores, global segment lead for Blockchain at AWS wrote in a blog post announcing the new AWS Blockchain Partners Portal. “We invite you to check out current blockchains and review reference architecture, deployment strategies, and development tools on our new portal page.”

Oh, and the company will launch an AWS Blockchain Competency next year, according to the blog.

Several companies have already built blockchain-based applications that are available on the portal “as one-click deploy.” These include a Sawtooth product for deploying distributed ledgers; a financial-grade ledger platform called Corda from R3; and a health care app by PokitDok that automates transaction processing.

Additional services from Samsung, Quorum, and Virtusa will be available in 2018.

Amazon is also seeking proposals related to health care and life sciences; financial services; supply chain management; security; or compliance. “For example, based on feedback from our health care and life sciences customers, we are interested in seeing proposals for identity resolution, auto-adjudication, and supply chain integrity applications,” Flores wrote.

It was probably only a matter of time until AWS boarded the blockchain train. Most other enterprise cloud and IT service providers already offer a service based on the technology or have one planned for early 2018.

Early adopter IBM launched a beta version of IBM Blockchain, an enterprise blockchain service based on the Linux Foundation’s Hyperledger Fabric, back in March. In August, Microsoft announced software to help enterprises adopt blockchain. Oracle debuted its Blockchain Cloud Service in October. And VMware plans to trial its blockchain technology next year.
