Summer of open source | Ali open source nearly 100 tasks online

About Come and participate to win huge prizes~

In 2021, the China Open Source Software Promotion Alliance COPU will lead the release of the "2021 China Open Source Development Blue Book", which covers the overall situation analysis, developer analysis, project analysis, and field cases of global open source today, and draws an "open source digital ecological map" . Let us fully see the Chinese power in the open source field.

The report states:

• The domestic company ranks first in the open source activity of Ali , and some index values are even the sum of other companies, and they are also doing well in terms of communityization/opening;
• Dubbo and RocketMQ two cloud-native middleware open source projects are in the Apache Software Foundation China project open source quadrant first square (globalization + influence two dimensions);
• China's Top 20 project list Nacos, Seata two middleware open source projects on the list.

This year, the 14 open source projects of Alibaba Cloud's native open source family have joined a series of university open source activities supported by the Open Source Software Supply Chain Lighting Program of the Institute of Software of the Chinese Academy of Sciences-Summer 2021. Official website of the event: _ https://summer.iscas.ac.cn/ _

Through this activity, students can experience in-depth real-world software development under the guidance of top open source instructors, and feel the charm of open source technology co-construction. There are no shortage of project mentors participating in this plan, such as the top Apache projects PMC & Committer, CNCF TOC, etc. The projects involve many popular directions such as microservices, containers, serverless, and chaos engineering.

Project Introduction

Apache Dubbo

Dubbo is a high-performance RPC framework open sourced by Alibaba in 2011, and it has gradually transformed from an RPC framework to a microservice ecosystem. Graduated from the Apache Software Foundation in May 2019 and became a top-level Apache project. In 2021, Dubbo 3.0 Preview was released, directly announcing the blueprint for the next-generation cloud native technology.

Open Messaging

In the era of cloud computing, messaging has become a key link in modern data-driven architecture. Message middleware can connect data sources, data processing engines, and applications. However, there are still two major problems in the messaging field on a global scale: First, the lack of vendor-neutral industry standards has led to the high complexity and incompatibility of various messaging middleware, and correspondingly caused the company's products to be inefficient and chaotic. And supplier lock-in and other issues. Second, the existing solution framework does not fit the cloud architecture well, that is, the non-cloud native architecture, so it cannot effectively provide technical support for emerging business needs such as big data, stream computing, and the Internet of Things. OpenMessaging discarded the historical baggage and went lightly, hoping to solve these shortcomings. In addition to linking cross-platform, cross-language, cross-product and cross-cloud standards, OpenMessaging will provide Cloud Native capabilities for cloud computing, hybrid cloud architecture, and achieve seamless migration of multi-cloud platforms. It is committed to providing financial, electronic One-stop solutions for business, IoT, big data and other fields. It has been developed for more than 4 years, and has so far included many popular open source projects including API Spec, OpenConnect, OpenChaos, OpenSchema, and DLedger.

Serverless Devs

Serverless has been a hot topic in the field of cloud computing in recent years. With its advantages such as extreme flexibility, pay-as-you-go, cost reduction and efficiency improvement, it has been sought after by many people. Cloud vendors are also constantly deploying in the serverless field. But with the development of time, some serious problems have been exposed in the serverless field. For example, manufacturers are locked in serious, there is no suitable developer tools, and the program is difficult to debug... For this reason, Serverless Devs came into being to solve Developers’ most fundamental demands in the development of Serverless applications are their own responsibility, with an attitude of open source and openness, to promote the goal of continuous advancement in the serverless field. Serverless Devs was born by Alibaba. It is not limited to Alibaba Cloud. It is open to cloud computing. Embrace the Serverless architecture with more Serverlessors. Serverless Devs is an open source project in the serverless field initiated by Alibaba. Its purpose is to contribute to an open source, open and vendor-free serverless developer tool with developers. It is hoped that this tool can be used by developers to develop Serverless applications. The life cycle plays a role, and it is hoped that developers can play with Serverless like using a mobile phone.

Dragonfly

Dragonfly is a P2P-based intelligent image and file distribution tool. It aims to improve the efficiency and speed of file transfer and maximize the use of network bandwidth, especially when distributing large amounts of data, such as application distribution, cache distribution, log distribution, and mirror distribution. In Alibaba, Dragonfly is called 2 billion times a month, and the amount of data distributed is as high as 3.4PB. Dragonfly has become an important part of Alibaba's infrastructure. Although container technology simplifies operation and maintenance most of the time, it also brings some challenges: for example, the efficiency of image distribution, especially when the image distribution must be replicated on multiple hosts. Dragonfly can perfectly support Docker and PouchContainer in this scenario. It is also compatible with containers in other formats. Compared with the native method, it can increase the container distribution speed by 57 times and reduce the registry network egress traffic by 99.5%. Dragonfly can make all types of files, mirrors or data distribution simple and economical.
