Digital Asset reported that Amazon Web Services (AWS) will cease operation of its fully managed blockchain service, 'Amazon Managed Blockchain (AMB)'. New customer sign-ups will be suspended from the 29th, and the service will also be terminated for existing customers in September next year. AMB is a fully managed blockchain infrastructure service that AWS has provided to enable users to build applications based on public and private blockchains. It allows businesses to access blockchain networks or query data in the AWS environment without having to directly build and operate blockchain nodes and related infrastructure.
