>>
>> = Rationale =
>> Skywalking includes these primary parts:
>>  1. Provide an anto-instrument sniffer, which is based on Javaagent and
>>  collects events and traces happened inside JVM, with little CPU/Memory
>>  cost.
>>  1. An extendable `tracing data protocol suit` with gRPC and HTTP
>>  implementations, is compatible for other language agent or SDK.
>>  1. Provide Collector, which accepts the `tracing data protocol suit`,
>>  and does the analysis and aggregation inside for detecting the
>>  relationships among applications and services, generating the metrics,
>>  and altering.
>>  1. Provided our own UI, which visualizes the topological graph of
>>  related applications and services, trace stack, metrics and alerting.
>>
>> Also, Skywalking team is passionate about community cooperations.
>> Skywalking is a supported tracer and member of
>> [[OpenTracing|http://opentracing.io]]. Also we take part in the
>> [[https://github.com/TraceContext/tracecontext-spec|TraceContext
>> Specs]], which is about `tracing context propagation format`. The
>> founder of the project, Sheng Wu, is the member of these organizations,
>>
>> There is a strong need for an open, easy-to-use APM towards helping
>> today's DevOps people to monitor their running systems, while also being
>> easy and transparent to maintain and modify.
>> The Skywalking has been an hot open source project in GitHub. We feel
>> that by moving to Apache it will help us work in a more global and open
>> way, presenting the project as a commercial friendly but vendor neutral

>> hope is also to make the Skywalking releases more reliable, as is

>> Skywalking was originally created by [[https://github.com/wu-sheng|Sheng

>> == Known Risks ==
>> The project is well known in global tracing and APM field, and live more

>> challenge for us. So far, the contributors, committers and confirmed
>> product use cases are all from China.
>> === Language and Culture ===
>> Concerns have been raised about language challenges and, as is typical
>> for developers not strong in english, aware that the community can be
>> shy in a debate or disagreement when english is used. Having looked
>> through the project's history this concern can be seen to be minor. The
>> commitlog is in english, and so are the tickets and the pull requests.
>> The website and documentation is equally both english and chinese. The
>> community has been strict upon itself to ensure it became and stays so.
>> The use of chinese should not be seen as a problem, it is a multilingual
>> world, but it is important that english speakers feel included and able
>> to contribute freely to the project without having to ask for
>> translations. To deal with poor or broken english it's important that a
>> gentler and inclusive community is fostered.
>>
>>
>> === Orphaned products ===
>> The contributors and community cooperation brings the project from a
>> small concept into a real APM system. So far, many companies, e.g.
>> Huawei DevCloud, dangdang.com, tydic, jd.com, have their own
>> independency contribute team for Skywalking. So this is not risk of any
>> signs of orphaned or abandoned code.
>>
>> === Inexperience with Open Source ===
>> The founder of the project, Sheng Wu, is an open source lover. He has
>> contributed for these open source projects: OpenTracing-Specification,
>> OpenTracing-Java, Motan, Hprose, OpenTracing specification-zh, and
>> apache/incubator-rocketmq.
>>
>> Hongtao Gao, our committer team member, is the major maintainer of
>> [[https://github.com/shardingjdbc/sharding-jdbc|sharding-jdbc]] and
>> [[https://github.com/elasticjob/elastic-job|elastic-job]] since 2014.
>>
>> The project are following these two experienced open source people's
>> guidance. And glad to learn from the Apache Way.
>>
>> === Homogenous Developers ===
>> The confirmed contributors list:
>> https://github.com/OpenSkywalking/Organization/blob/master/README.md#
>> contributors.
>> As mentioned above in the [[#community|Community]] section.
>>
>> === Reliance on Salaried Developers ===
>> First of all, most members of the PMC and Committer Team, are paid by
>> their employers (Huawei, Tydic, dangdang.com and OneAPM) to contribute
>> to this project. But we have to say, many of them have more than one
>> employer in the past 3 years contribution, but the contributions are
>> never stopped. We don't just depend on salaried contributors only.
>> Skywalking itself and the distributed tracing field are very attractive
>> and important for every company the contributors work in, and they have
>> no reason to stop them. Contributions and new committers are expected.
>>
>> === Relationships with Other Apache Products ===
>> HBase was used as a backend before being rewritten, and that ZooKeeper,
>> httpcomponents, log4j and junit are used. Also we are considering all
>> java projects, especially big data technology, e.g. Hadoop, Hbase,
>> Cassandra.
>>
>> === A Excessive Fascination with the Apache Brand ===
>> The ASF has a strong brand, and that brand is in itself attractive.
>> Skywalking will benefit from world wide collaboration and use cases. The
>> Apache brand will be duly respected and honored in regards to  marketing
>> and publicity. Further more, with the help of Incubator PMC, we will
>> make every effort to follow the rules and policies of the ASF.
