Hello everyone , I am a little weeks , Zhou qiluo's Zhou , This article explains traditional databases and cloud native databases through interesting scenarios , Let you understand the trend of future database , Originality is not easy. , If you think the article is well written , Remember that Sanlian supports poor bloggers

Brief introduction of database

Whether using wechat , Or the king , These applications that serve users have a very important thing , That's it data , Why can we find out the game records of the year before last , Why does wechat chat log in sync , In fact, these data are stored and managed in some way , Database is the product of data management , Complete the basic operations of adding, deleting, modifying and querying data , Up to now, database technology has also gone through several stages , Next, I will start from the manual management stage , File system stage and database management system stage , Describe the development process of the original database .

Manual management stage

In the early days of computer , Computer technology is immature , The software and hardware are not perfect , Computers in this period are computers , There is no storage device directly storing data on the hardware , Software , There is no operating system and upper software , The data processing method is batch processing .

Data manager	people
Data oriented object	An application
Data independence	Not independent , Dependent procedure
Data sharing	No sharing
Data structure	Unstructured
Data control	Application control

File management phase

The main mark of this stage is that the computer has special software for managing the database , file system ,20 century 50 S to 60 years , With the continuous progress of computer technology , Computers are no longer satisfied with data processing , Also used to manage data , First, from the hardware , With a hard disk , CD and other direct storage hardware devices , On software , The operating system was born , And there is special software for managing files , It is called document management system for short , This is the document management stage .

Data manager	file system
Data oriented object	An application
Data independence	Poor independence
Data sharing	Poor sharing
Data structure	There is a structure in the record , The whole has no structure
Data control	Application control

Database system phase

Here ⼀ In phase , The data in the database is no longer ⾯ Answer to sb ⽤ Or a program ,⽽ yes ⾯ Respond to the whole ⽤ Of .

Data manager	Database management system
Data oriented object	The whole application
Data independence	High physical and logical independence
Data sharing	High sharing
Data structure	Overall structure
Data control	Database management system for control

What is the current situation of traditional databases ？

Traditional database is a collection of data organized and stored according to a certain data model . This data set has the following characteristics ： The data structure is independent of the application that uses it , The increase in data 、 Delete 、 Change 、 It is managed and controlled by unified software .

Long before the birth of Cloud Computing , Traditional self built database is the only choice for all developers . However, as the number of users increases and the business complexity increases , The shortcomings of traditional self built databases are becoming more and more obvious .

Such as security issues , Need to prevent all kinds of attacks , Self built databases need to be implemented by ourselves , And the cost is high , At the same time, we also need to repair the database security vulnerabilities . The question of reliability , Stand alone example , There is no data disaster recovery processing , Need extra cost to establish data disaster recovery . High hardware cost , In order to deploy the database , Developers need to buy expensive database servers . Disposable hardware costs are high , Also consider hardware loss , The cost of later maintenance and replacement of hardware . The operation and maintenance cost is high , It takes a lot of manpower and material resources to maintain the hardware 、 Maintain the operating system 、 Maintain database software and so on .

In addition to self built database , There is no better choice ？ The answer is yes , Using cloud native database allows you to apply for a database instance that can basically solve all the above problems in a few minutes , Isn't it a beautiful thing .

What is Yunyuan ？

Cloud native （Cloud Native） It's a way to build and run applications , It's a set of technical system and methodology .

Cloud+Native,Cloud For cloud platform ,Native Indicates that the cloud environment is considered in the design of the application , Native applications run in the best posture on the cloud , Make full use of and give full play to the flexibility of cloud platform + Distributed advantage .

With the development of times and Technology , Evolving , Container technology 、 Microservices 、 Sustainable delivery 、DevOps, Four key points of cloud primordial .

What is cloud native database ？

Cloud native database , It is built through cloud platform 、 Deploy and distribute database services . It uses PaaS In the form of , Compared to traditional databases , Cloud native database provides better accessibility and scalability .

Advantages and characteristics of cloud native database ？

Fault tolerance mechanism ： The fault-tolerant mechanism of cloud native database includes automatic migration after downtime , Automatic fault isolation , Load balancing, etc

Stretch and stretch ： It can scale automatically according to the usage rate , Second expansion , Greatly reduce the user's use cost

Safe isolation ： Cloud database uses shared pooling technology to improve computing efficiency 、 Storage 、 Utilization of network and other resources , In addition, the isolation of multi-user security and stability is also considered , Avoid information disclosure or attack

Flexible billing ： Support the formulation of multiple pricing strategies according to volume , Users can choose the optimal measurement mode according to their business conditions , Thus saving user costs

Easier to manage ： It can achieve the transformation from self-service operation and maintenance to automatic operation and maintenance , Have the ability of automatic anomaly analysis and diagnosis

Ultimate experience ： User's application for database 、 establish 、 monitor 、 Fault location is done in the simplest way , Give users an extremely convenient experience

……

At the end

Clouds are hot , Software development is undergoing a cloud native transformation , Everything starts to build from scratch on the cloud , Cloud database is superior to traditional database in function and reliability , In addition, the blessing of scalability , Let cloud native database represent the future trend of database .
