Please describe your proposed solution.

PART 1 (current proposal)

Kubernetes is the most popular workload orchestration platform in the world. It has become a staple for deploying software to support production environments, particularly for web3 companies. This is no different in Cardano. Many stake pool operators and dapp developers build their software as Docker containers and deploy them onto Kubernetes.

Decentralized Orchestras

A Maestro Decentralized Orchestra is composed of the following workloads and services:

• Cardano Node
• Cardano DB Sync
• DB Sync Koios functions
• Scrolls Reducers
• Redis database
• Postgres database
• REST API for querying Postgres and Redis serving blockchain data

Requirements for running an Orchestra

• A Kubernetes cluster

PART 2 (future proposal)

Vet and onboard Orchestra operators to distribute query traffic from a load balanced proxy to Orchestras around the world. This is similar to the approach taken by Koios and Freeloaderz.

PART 3 (future proposal)

Public monitoring dashboard and auto rotations based on the health of orchestras.

How does your proposed solution address the challenge and what benefits will this bring to the Cardano ecosystem?

The Maestro Orchestra is a tool that will alleviate the burden of running Cardano infrastructure and make it easy for dApp developers to interact with the network: point to a Kubernetes cluster and apply an Orchestra operator.

Cardano developers can leverage powerful infrastructure code to bootstrap quick and efficient access to the network. They can also contribute to the repository to help improve the Kubernetes operator for the entire ecosystem. This will create a network effect that we have already seen in many open source Cardano projects.

Orchestras are being leveraged internally as part of the Maestro platform. This effort will help expand our platform to the rest of the ecosystem as part of a feature-complete open source project.

As a result of this project, developer onboarding onto the Cardano ecosystem will be much easier and will lead to Cardano becoming a top blockchain for building dApps and collaborating with the rest of the ecosystem.

How do you intend to measure the success of your project?

There are a number of key ways to measure the success of this project

• Cardano developer adoption: the number of organizations leveraging orchestras to build dApps
• Github activity: stars, issues opened and closed, and forks
• Survey sent to the community to gather user data and address feedback

Please describe your plans to share the outputs and results of your project?

The project will be an actively maintained Github repository in the maestro-org Github organization.

What is your capability to deliver your project with high levels of trust and accountability?

Maestro has a proven track record in providing Cardano infrastructure services: Blockchain Indexer, Transaction Manager and Turbo Transaction. In particular Maestro’s indexer endpoints averages 300,000 requests / day and is being used to power top projects and dapps on Cardano. This project is an extension of what Maestro has already built internally.

What are the main goals for the project and how will you validate if your approach is feasible?

The final deliverable of this project will be a Github repository that includes the following:

• The Kubernetes operator implementation to facilitate the management of an Orchestra
• Instructions for how to install and use the operator

The repository will be actively maintained during the allotted development time until the final deliverable described above is fully implemented. Before completion, any code that is made public will be freely available to use by any developer in the ecosystem.

The ultimate goal of this project is for it to become a key piece of open source infrastructure in the ecosystem. The Orchestra will significantly decrease the time it takes for Cardano developers to access on-chain data and build scalable dapps.
