Don't ask me why I always pay attention to the pulse , Because there is truth in the pulse . Today's topic is ： Why are big factories keen on making wheels ？

There are too many discussions about building wheels , Take a few pictures at random .

In fact, it's not just big factories , Many medium-sized companies also make wheels , As the saying goes, there are hundreds of different kinds of people . The reasons for making wheels can be summarized in the following categories .

1、 Other people's wheels don't work well

Many wheels of open source products are ready , But there is often satisfaction 80%-90% The needs of , in order to 10% Make a wheel , There are also a lot of people in .

2、 In order to demonstrate technical strength , Good promotion

What you make is always the best .

3、 I really don't want to make , Your need priorities are too low

Some middle ground teams , Divide the service users into one ring and two rings N Ring , When your needs are outside the Third Ring Road , What do you do ？ I can't count on it , You can only make it yourself .

4、 By making wheels , Enhance technical strength .

Talk to people about business systems these days , It's not easy to talk . Chat JVM tuning ,RPC/message/ Distributed scheduling comes from a set of , It can also be called “ Unified communication language ”, Both the interviewer and the interviewer are happy .

Is there any advantage in building wheels ？
To the old G say , There are .

After all, business is king , In order to meet the business , Try every means to solve the problem . If no wheels are available , You can change one . That year dubbo No maintenance , Dangdang also tossed dubbox. The tools you rely on / The platform team doesn't answer your needs , You have to make it yourself .

How to tune a company's many “ wheel ”？ It looks innovative , May be “ Build a broken car behind closed doors ”！ The old G Think , There are several directions to consider .

1、 Or determine the service relationship between the organization and the business at the company level .

The Top-Down Problem solved , Don't let the children below scramble for territory and toss around . For example, the social business department and e-commerce business department of a factory ,RPC frame / news / journal / Whether the scheduling task management needs to be unified ？ You don't have to , The group company assesses the revenue of the final business division , You focus more on making basic wheels , There is less manpower to do business services . Of course, this tests the management ability of the leadership , How much does it cost to do things , Whether it is a contract responsibility system , people // goods / matter / Business accounting ledger .

If there is a middle office team to do the function of basic middleware , Also clarify the assessment of the team . The needs of social business unit and e-commerce business unit , You should be satisfied . Don't distinguish between intimacy and estrangement ,KPI It's aligned , Let the people below do things and brush their faces .

For example, in some companies , If you don't know what platform to build , Relationship with several other platforms in the company , You can't be promoted to a certain level .

3、 Encourage cooperation . It is said that the income of Microsoft employees is similar to impact relevant .

impact Emphasis on cooperation , Talking to the boss review At the same time, you should also write what teams you work with and what results you get , The more performance you get through a cooperative team , The higher the performance appraisal . So as to avoid involution .

4、 It depends on the insight of the technology leader . As the saying goes, it's better , The next must be the next .

Mr. Wang Yuan of Netease sighed and said , If DDB This product has long been open source , There is no ShardingSphere What's the matter . Good things that others open source , You look unhappy today , Self made possibilities 2 No one has maintained it since . But there are millions of open source people adding new features and fixes bug, This is it. open Power . Technical leaders have to judge , What should stand on the shoulders of giants , What should keep its originality , And what should be shared , Have stronger vitality .

Some wheels are very popular today , It may be a grain of sand in the long river of history .

Today you laugh at other people's code low, Maybe future generations will mourn and not learn from it , It also makes future generations mourn for future generations .

To build the wheels , Have to be careful , Encourage everyone .
