Cello can make use of Docker APIs to manage blockchain clusters. Equally, if not more important, it can be integrated with a Hyplerledger Explorer dashboard to bring detailed operational knowledge and ledger detail to the enterprise IT team.

Cello can:

• Provisioning customizable blockchains instantly (e.g., a 6-node fabric chain using PBFT consensus)
• Maintaining a pool of running blockchains healthy with no manual operations involved
• Checking the system’s status, scaling the chain numbers, changing resources, etc. through a dashboard

Hyperledger Cello (HLC) is a blockchain provision and operation system, which helps people use and manage blockchains in a more efficient way.

Based on advanced blockchain technologies and modern PaaS tools, Cello provides the following major features:

• Manage the lifecycle of blockchain networks, e.g., create/start/stop/delete/keep health automatically.
• Support customized blockchain network config, e.g., network size, consensus type.
• Support multiple underly infrastructure including bare-metal, virtual machine, vSphere, native Docker host, swarm and Kubernetes. More supports on the way.
• Extends with advanced features like monitoring, logging, health and analytics capability by integrating with existing tools like ElasticStack.

Using Cello, blockchain developers can:

• Build up a Blockchain as a Service (BaaS) platform quickly from scratch.
• Provision customizable Blockchains instantly, e.g., a Hyperledger fabric v1.x network.
• Check the system status and manage chains, upload smart contract and test… through dashboards.
• Maintain a pool of running blockchain networks on top of bare-metals, virtual clouds (e.g., virtual machines, vsphere Clouds), container clusters (e.g., Docker, Swarm, Kubernetes).

Forma - a multi-cloud orchestrator

Multi-cloud Remote Blockchain Infrastructure Orchestrator

If you can blindly trust other parties to have your infrastructure and centralize it for the whole network, then a blockchain is not what you need.

In a “Blockchain as a Service” a cloud provider keeps all the infrastructure for every company. They make it quite easy to get started but what if you want the infrastructure on your premises, or if you’d like to use another cloud provider for the infrastructure?

In the end, companies get locked into their offerings, after all, that’s their business, to sell their infrastructure with value added services such as centralized Blockchain services.

On the other hand, Forma doesn’t centralize the infrastructure (as it connects remotely to your infrastructure) nor takes control away from the companies.

This enables a whole new world for the Enterprise Blockchain world:

• Networks can today be made of multi-cloud infrastructure.
• Components will be able to be migrated from one cloud provider to another — without lock-in.
• Companies don’t have to blindly trust a single party to keep everything for them (all the data). We don’t store it, therefore, don’t access it.

But also, it brings all the benefits that a Blockchain as a Service would:

• No company has to invest hundreds of hours setting up their infrastructure.
• Forma streamlines the tasks that require coordinated information from multiple companies, such as installing smart contracts.
• Onboarding new companies is easier than ever, making the network effects the center of the networks’ growth.
