| # Dragonfly Graduation Proposal | ||
|
|
||
| [Dragonfly](https://d7y.io/) joined the CNCF as a sandbox project in October 2018 and became an | ||
| incubating project in April 2020. In January 2020, [Nydus](https://nydus.dev/) became | ||
| a sub-project of Dragonfly and was widely used for image acceleration. | ||
| In April 2021, the Dragonfly v2.0 was released after architectural optimization and code refactoring. | ||
|
|
||
| After an extensive period of development and production experience, Dragonfly is not only widely used in image acceleration, | ||
| but also has many use cases in file distribution and AI model distribution. The community has made great progress in growing, | ||
| it is governed by partners including Alibaba Group, Ant Group, Baidu Group, Dalian University of Technology, ByteDance, | ||
| Intel and JiHu. The project maintainers believe that Dragonfly is ready for graduation. | ||
|
|
||
| ## Introduction | ||
|
|
||
| Dragonfly provides efficient, stable and secure file distribution and image acceleration based on P2P technology | ||
| to be the best practice and standard solution in cloud native architectures. | ||
| It is designed to improve the efficiency and speed of large-scale file distribution and used in the fields of file distribution, | ||
| AI model distribution, cache distribution, log distribution and image distribution. | ||
|
|
||
| With the production practice, Dragonfly based on P2P technology to accelerate the image is insufficient to support | ||
| faster container launching, such as the Function as a Service (FaaS). | ||
| Therefore, we created Nydus as a sub-project of Dragonfly to address this need | ||
| and [Nydus Snapshotter](https://github.com/containerd/nydus-snapshotter) become a sub-project of containerd | ||
| which is an external plugin of containerd for Nydus. | ||
| Nydus implements a content-addressable file system that enhances the current OCI image format with | ||
| faster container launch speed, better image space and network bandwidth efficiency, and end-to-end data integrity. | ||
|
|
||
| ### Image Acceleration | ||
|
|
||
| Dragonfly supports various container clients such as containerd, Docker, cri-o, ORAS, etc. | ||
| It provides three solutions for image acceleration. The first solution is to use Dragonfly to distribute | ||
| images based on P2P technology, which is suitable for large-scale cluster. The second solution is to use Dragonfly and | ||
| Nydus to distribute accelerated images, which is suitable for large-scale cluster and faster container launching. | ||
| The third solution is to use Nydus to distribute accelerated images, which is suitable for faster container launching. | ||
|

|
||
| ### File Distribution | ||
|
|
||
| Dragonfly supports large-scale file distribution and uses P2P technology to eliminate the impact of | ||
| origin bandwidth limitations. It supports file distribution of protocols including HTTP, HDFS, etc. | ||
| Additionally, it also supports different object storage protocols includes S3, OSS, OBS, etc. | ||
|
|
||
| Add [Dfstore](https://d7y.io/docs/concepts/terminology/dfstore) to expand the file distribution capability, | ||
| it can depend on different types of object storage, such as S3, OSS, OBS, etc. to provide stable object storage capabilities. | ||
| Dfstore uses the entire P2P network as a cache when storing objects. Depend on object storage as | ||
| the backend to ensure storage reliability. In the process of object storage, P2P cache is effectively | ||
| used for fast read and write storage. | ||
|
|
||
| ### AI Infrastructure | ||
|
|
||
| Dragonfly supports distributing data during AI training and AI inference. | ||
| In the AI inference, Dragonfly supports [Triton Server](https://github.com/triton-inference-server/server) and [TorchServe](https://github.com/pytorch/serve) | ||
| to use Dragonfly distribution model. In the AI training, [Fluid](https://github.com/fluid-cloudnative/fluid) downloads | ||
| dataset through Dragonfly when running based on [JuiceFS](https://github.com/juicedata/juicefs). | ||
|
|
||
| There are many use cases in the community, using Dragonfly to distribute data based on P2P technology. | ||
| In the inference, the concurrent download model of the inference service can effectively relieve the bandwidth pressure of | ||
| the model registry through Dragonfly, and improving the download speed. Users can embed the model into the | ||
| accelerated image and use Dragonfly and Nydus for faster container launching. | ||
|

| ## Graduation State Criteria | ||
|
|
||
| ### Have committers from at least two organizations. | ||
|
|
||
| Dragonfly has [maintainers (committers) from](https://github.com/dragonflyoss/Dragonfly2/blob/main/MAINTAINERS.md) | ||
| Alibaba Group, Ant Group, Baidu Group, Dalian University of Technology, ByteDance, Intel and JiHu. | ||
|
|
||
| ### Have achieved and maintained a [Core Infrastructure Initiative Best Practices Badge](https://bestpractices.coreinfrastructure.org/). | ||
|
|
||
| Dragonfly’s OpenSSF best practices badge can be seen [here](https://bestpractices.coreinfrastructure.org/projects/7103). | ||
|
|
||
| ### Have completed an independent and third party security audit with results published of similar scope and quality as [this example](https://github.com/envoyproxy/envoy#security-audit) which includes all critical vulnerabilities and all critical vulnerabilities need to be addressed before graduation. | ||
|
|
||
| The security audit is almost over with OSTIF. When the security audit is over, I will update the content as soon as possible. | ||
|
|
||
| ### Explicitly define a project governance and committer process. The committer process should cover the full committer lifecycle including onboarding and offboarding or emeritus criteria. This preferably is laid out in a GOVERNANCE.md file and references an OWNERS.md file showing the current and emeritus committers. | ||
|
|
||
| - See [GOVERNANCE.md](https://github.com/dragonflyoss/Dragonfly2/blob/main/GOVERNANCE.md) that describes governance | ||
| guidelines and maintainer responsibilities. | ||
| - See [OWNERS.md](https://github.com/dragonflyoss/Dragonfly2/blob/main/OWNERS.md) about current and emeritus maintainers. | ||
| - See [CONTRIBUTING.md](https://github.com/dragonflyoss/Dragonfly2/blob/main/CONTRIBUTING.md) for general contributing guidelines. | ||
|
|
||
| ### Explicitly define the criteria, process and offboarding or emeritus conditions for project maintainers; or those who may interact with the CNCF on behalf of the project. The list of maintainers should be preferably be stored in a MAINTAINERS.md file and audited at a minimum of an annual cadence. | ||
|
|
||
| - See [GOVERNANCE.md](https://github.com/dragonflyoss/Dragonfly2/blob/main/GOVERNANCE.md) that describes governance | ||
| guidelines and maintainer responsibilities. | ||
| - See [MAINTAINERS.md](https://github.com/dragonflyoss/Dragonfly2/blob/main/MAINTAINERS.md) about current maintainers. | ||
|
|
||
| ### Have a public list of Project adopters for at least the primary repo (e.g., ADOPTERS.md or logos on the Project website). For a specification, have a list of adopters for the implementation(s) of the spec. Refer to [FAQs](https://github.com/cncf/toc/blob/main/FAQ.md#what-is-the-definition-of-an-adopter) for guidelines on identifying adopters. | ||
|
|
||
| The public list of Dragonfly adopters is in the [ADOPTERS.md](https://github.com/dragonflyoss/Dragonfly2/blob/main/ADOPTERS.md). | ||
