Hyperledger Cello aims to bring the on-demand “as-a-service” deployment model to the blockchain ecosystem to reduce the effort required for creating, managing, and terminating blockchains. It provides a multi-tenant chain service efficiently and automatically on top of various infrastructures, e.g., baremetal, virtual machine, and more container platforms. An Operator, on the other hand, is a method of packaging, deploying and managing a Kubernetes application which in this case, is a Hyperledger Fabric Deployment.
Kubernetes is the preferred choice of many developers when it comes to deploying their Fabric Application. The cello project provides a way for them to quickly set up their fabric infrastructure while still maintaining a high level of customization whenever required. Operators allow us to make our application highly automated by describing the various events and the resulting actions making operators fit for implementing highly sophisticated business logic in the production stage.
The cloud-like capabilities that are encoded into the Operator code can provide advanced user experience, automating such features as updates, backups, and scaling. All of this is accomplished using standard Kubernetes tools, CLI and API.
