Tdsql-c serverless: help start-ups achieve cost reduction and efficiency increase

7 month 15 Number , I had the pleasure of attending

ArchSummit 2022 Global architects Summit （ ShenZhen Railway Station ）

, Among them, teacher Yang jueji explained TDSQL-C Serverless  The database gave me a deep impression .

TDSQL-C Serverless Its feature is that it enables enterprises to use water 、 electric 、 Use cloud database services like coal . Users do not need to pay for idle databases , How much to use . This technology can help enterprises greatly save costs in many business scenarios .

Because I used to be responsible for purchasing the company's servers , So I know that the cost of cloud servers is not small . And in response to some activities , The configuration is still very expensive , But in fact, in most cases, server resources are rarely used . especially 2020 Because of the epidemic , We have returned many servers , But actually, I didn't return much money . So if you can pay according to the actual use , That will save a lot of money for our enterprise .

Before listening to this class , I don't think it's a problem to charge for not using ECS , Isn't everyone doing this ？ But is this really reasonable ？TDSQL-C The person in charge of Yang jueji said ：" This is not reasonable ”. Why can't we use cloud servers like natural water ？ The bulk of cloud server costs is nothing more than computing resources and storage resources . Why can't we charge by use ？

I understand there are two reasons ：

First of all ： It's technically difficult to implement .

second ： Enterprises have no motivation .

Yeah , If you can make money easily , Who would work so hard to make money ？ But teacher Yang jueji and his team , Did this thing .

TDSQL-C Serverless Application scenarios of

• Scenarios where business data is not accessed for a long time .

• Scenarios with low frequency of business visits . such as ： Personal blog , Vertical community forums or some business wechat apps .

• Enterprise internal development and testing environment . Use it at work , Rarely used after work .

• Usual CPU Few resources are used , More resources are used only when there are occasional activities or complex queries .

In the above scenarios , Use TDSQL-C Serverless It can significantly reduce the cost of cloud servers . at present TDSQL-C Serverless This product has been widely used in Tencent . such as , Tencent cloud 、 Cloud hosting of wechat apps 、 Tencent Lexiang community, etc , If you need it, you can try it first .

Technological innovation is not so easy

How to achieve it specifically ？ We can see from the following architecture diagram ,TDSQL-C The computing layer and storage layer are separated .

After the separation of calculation and storage , Then you can charge separately . Finally, we can realize no charge without using . But in the process , There are many problems that need to be solved . such as , You have to support the automatic expansion and contraction of instances according to the business load , And the speed should not be too slow , After all, I sometimes do activities and go up very soon ; Another example , If the application has not been accessed by users for a long time, it stops , What if someone suddenly uses it ？ How to give users the fastest response in this scenario ？ These solutions are explained by teachers in class , If you are interested, you can find this information .

My inspiration

Existence is unreasonable , Even these habitual things often limit our imagination , No imagination, no innovation . Technological development often brings a lot of opportunities for innovation , This is an inspiration I got . in fact , If you are willing to ask more why , You will find that many services are not necessarily like this in the future . For example, current mobile phones still need to charge high hardware costs . In the future, when the hardware cost is getting lower and lower , More and more resources are used on the cloud , Is it possible to pay for the use of resources ？ This is possible . Another example is smart cars , In fact, it is the same truth with mobile phones . Stretch it out , All things are intelligent , All computing resources are used 、 Storage resources . You see , This technology of teacher Yang may be one of the most mainstream technologies in the future , Worth waiting for .

Finally, share the teacher's PPT：
