The sharing economy is blooming all over the world in 2015，The most representative sharing economy company in China is Didi，After the merger with Kuaidi, it has become the largest car service company，Didi recently completed US$2 billion in financing，Valuation reaches US$15 billion，From the establishment of the company to becoming a giant，It only took 3 years。Rapid growth continues，Didi recently launched a ride-hailing business with high profile，Pony Ma Huateng, Chairman of Tencent’s Board of Directors, serves as its spokesperson，This is Ma Huateng’s first time endorsing a product，This shows how seriously Didi is valued in the Tencent system。The company is growing so rapidly，Huge investment、WeChat red envelope、Didi Team，All contributions are indispensable。There is another one that has received little attention from the outside world，How Didi’s technology successfully supported rapid business development？The answer is cloud computing，Didi technology can handle it easily，Tencent Cloud is the hero behind the scenes。

Compared to traditional Internet business，Didi has unique business characteristics。

Business has obvious peak 188bet online sports betting and valley characteristics，There will be more orders during rush hours，Carry out subsidized marketing such as free ride orders on Mondays, which will increase the number of orders；Business has very high requirements on stability and robustness，User cannot call a car，The driver cannot receive the order，Unable to complete billing，Will seriously affect user perception；Business related to payment has a high level of security，If hacked, it may disrupt the entire transportation system，Having resources like hundreds of millions of vouchers obtained by hackers will cause huge losses...

The above business characteristics require that the entire system has sufficient flexibility、Stability and security，It is difficult for start-ups to build a system that has the above capabilities at the same time，Lack of resources、Lack of talent、Lack of time、Lack of experience。

Didi CTO Zhang Bo revealed this when he was a guest at Tencent Cloud Living Room，Didi Technology has gone through a painful period。When established in 2012，Only two servers，Initially these two servers can basically solve all problems，At the end of 2014, Didi and Kuaidi received huge investments from Tencent and Alibaba respectively，launched a money-promoting marketing war that could be recorded in the annals of business history，Explosive growth in orders。Didi team expects orders to grow by 10%，And prepared a technical plan，After the marketing war begins，Orders increased by 500%，Far exceeded the team’s expectations。At this time, Didi’s original technical architecture cannot support it at all，The system is stuck、Many problems with downtime。

This phenomenon has become very common on the mobile Internet: overnight，Surge in business volume，Some of it is because of good luck，For example, footnotes；Some of it is because of marketing effects，For example Didi。Anyway，The success of the business 188bet online sports betting line will bring pressure to the technical line。

Didi’s solution is，Choose to migrate all businesses to Tencent Cloud。Tencent is an investor in Didi，What’s more important is that Tencent Cloud supports WeChat、QQ, these two giant applications，Experienced the great test of super applications such as WeChat red envelopes，In stability、Security、The flexibility can support Didi。

Why is Didi’s success inseparable from cloud computing?

If there is no cloud computing support，Didi’s business is almost unable to operate normally。If Didi purchases server resources by itself，One is being deployed、Not enough experience in operation and maintenance、Not enough time，And lack of experience，Not feasible；The second will cause huge waste，In the middle of the night、During business hours，Didi’s business volume will be low，Using cloud computing resources，Essentially sharing computing resources with all businesses on Tencent Cloud。Didi in order to migrate its business to Tencent Cloud，Conducted a lot of renovation work，At the same time, a new architecture design was carried out for the business、Hierarchical classification，Summarized a lot of technical experience in developing businesses such as Didi。

On the other hand，Didi also attaches great importance to big data，This also puts forward requirements for cloud computing。

Didi business after forming scale，Pay more and more attention to the value of big data，Didi CTO Zhang Bo said，Big data is the heart of Didi。Didi has been trying to apply big data in the following aspects:

1. Match supply and demand.Every time a passenger initiates a ride request，Which nearby drivers will the order be sent to，How to quickly select the most suitable one after multiple drivers grab orders，Didi already has an algorithm。The matching algorithm is continuously improved based on massive data analysis，The accuracy 188bet app download of the algorithm determines the user experience and overall efficiency，At this point，Uber、Didi people have been competing secretly。

2. Precision marketing.Didi’s rapid growth，Inseparable from red envelope marketing combined with WeChat。Didi Red Envelope is already a very complex marketing system，To whom the vouchers will be given、How many vouchers are given、Free special car ticket, express ticket or free ride ticket，These are determined by algorithms based on massive data analysis。

3. Supply and demand forecast.Based on massive historical order records in different cities、User location data、Vehicle location data，Didi is gaining more and more comprehensive control over the city’s traffic data。Based on these data Didi can discover urban traffic patterns from the data、Forecasting vehicle demand characteristics、Predict the city’s transport capacity，In turn to the driver、To the public、Provide advice to transportation planning department。

4. User portrait.Didi plans to connect the passenger data it has with Tencent’s personal credit system，Such a passenger’s bad behavior record will affect his personal credit report，In turn, if there is no similar behavior, you can get a higher credit score，With Tencent Internet Finance、Many e-commerce businesses are linked together，For example, in the future, users can use QQ credit to ride directly。

5. Automatic billing.In the future Didi can navigate based on intelligent routes，According to the origin and destination，And the waiting time for the journey，Traffic conditions、Weather and other factors，To achieve automatic billing。In this way, passengers can get off directly after taking the bus，Didi backend will deduct the fee，Avoid the waiting time between driver and passenger to confirm payment，And bad behaviors such as driver detours。

Prerequisites for each of the above big data applications，Both require 188bet sports betting app download strong data analysis capabilities，And this must be achieved through computing clusters。Although the market capitalization has exceeded 150 US dollars，Didi is still a young company，It’s hard to imagine it can do so many things on big data。Because big data has always been a lofty thing in the past，Need high-end talents、Requires a computing cluster、We need a powerful algorithm... Didi can easily eat the "big data" cake，Precisely because it uses cloud computing。Cloud computing platform can provide distributed computing capabilities、Massive data processing capabilities、Mass data storage capability、Even some basic big data mining capabilities。Business-level data mining still needs to be done by the entrepreneurial team themselves，So Didi has recruited corresponding talents，Form a professional team，Make big data the heart of Didi。

Didi is essentially a travel service provider based on the sharing economy，It needs to be robust、Stable、Flexible and secure system to meet complexity、Real-time and safe travel needs。Didi is also a big data company，It collects more and more travel data，And improve users’ travel experience based on these data、Improving the order-taking efficiency of drivers、Improving the city’s transportation efficiency，This is of huge value，It is also the cornerstone of Didi’s business model。Therefore，Whether it is satisfied with Didi’s basic business，Looking at the future based on the imagination of big data，Cloud computing is a major contributor to Didi’s success。

Didi is just the most representative example。More and more entrepreneurs are benefiting from the rapid development of cloud computing industry。Their business development cannot be separated from the cloud computing platform，Meanwhile，Cloud computing also helps them use big data to improve efficiency、Extend more businesses，Big data is originally out of reach for entrepreneurs，With cloud computing platform，Anyone can “eat big data”。The future cloud computing 188bet sports betting app download platform will help more entrepreneurs succeed，Become the infrastructure for Internet + business upgrade。
