Is your database "cloud native"?

Database is one of the three basic computer software , Surface software that is more likely to receive attention than operating systems , The database is like an iceberg buried in the deep sea , Although it exists, few people look at it .

Database is also called data management system , It means that the processed data is stored together in a certain way , It can be shared by multiple users 、 Data sets that minimize redundancy , A database can consist of multiple data table spaces （Tablespace） constitute , The user can run add to the data in the file 、 Intercept 、 to update 、 Delete and other operations .

With the rapid development of Internet , The amount of data is also growing explosively , In the past, traditional databases obviously could not keep up with the huge explosion of the Internet , Coupled with the booming development of Cloud Computing , Cloud database has become a new trend .

2014 year ,Amazon Introduction Aurora, With low performance 、 high-cost 、 The advantage of high availability attracts a large number of customers and followers , And after that 6 In the past years, it has been among the top three camps in the world .

Cloud on database is an irreversible trend , In the future, cloud databases will be divided into two types , One is “ Jian Yun Yun ” Of , The other is “ Cloud based construction ” Of . The real cloud needs to be in the architecture design 、 The development way 、 All phases and aspects such as deployment and maintenance are redesigned based on the characteristics of cloud , So as to build a new cloud database , Cloud native database .

Your database “ Cloud native ” Did you? ？

Cloud native （CloudNative） It's a combination ,Cloud+Native.Cloud Indicates that the application is in the cloud , Not the traditional data center ;Native Represents that the application is designed with the cloud in mind , Native designed for the cloud , Run in the best posture on the cloud , Make full use of and give full play to the flexibility of cloud platform + Distributed advantage .

The cloud native database is a database based on the cloud native architecture , We can compare it with the traditional database system .

It also needs storage and calculation , When there's too much data , The database needs to be expanded , The traditional expansion process is very long , And it's painful to shrink after the business peak , It often leads to a great waste of resources , It's also hard to cope with the fast changing capabilities required by the business layer , This is one of the biggest drawbacks of traditional architecture .

by comparison , Cloud native database uses virtualization technology to pool resources , This is the core logic of cloud nativity , Let the original independent data , Merge into an invisible cloud pool . For example, in the cloud native computing storage separation architecture , Business nodes can calculate freely according to their needs 、 Storage for rapid expansion and reduction of capacity and other operations .

The core of cloud native database is the separation of storage and computing , At the same time, it must have high performance 、 Highly scalable 、 Uniformity 、 Meet the standard 、 Fault tolerance 、 Features such as ease of management and multi cloud support . For example, we need to 10 Node cost 10 A query completed in minutes , In the use of 100 In the case of nodes, it only takes 1 minute .

As a cloud platform , The cloud native database uses PaaS In the form of , It's also often called DBaaS（ Database and services ）, With the increasing importance of cloud native data and massive computing , People attach importance to providing enterprises with enhanced reliability and scalability through the deployment of such services .

Think about the number of applications you need to use every day , From instant messaging applications such as wechat to applications such as AE And other highly specialized applications , Both require secure login 、 User profile 、 Custom features 、 Content delivery, etc , These are exactly the scenarios where cloud native databases can provide users with solutions .

The future of databases ： Cloud native + Distributed

World famous consulting company Gartner Pointed out that , The cloud will dominate the future of the database market , To 2022 year ,75% Will be deployed or migrated to the cloud platform , Only 25% The database will run locally .

As businesses become more digital 、 Intelligent , The amount of data storage faced by enterprises will be even greater , Facing the challenges brought by more emergencies , Want to reduce cost and increase efficiency , Better data intelligent decision-making , The database needs to fully enter the cloud native + The age of distribution .

Distributed database is composed of multiple interconnected databases , These databases are combined to form a single user oriented database . In fact, they are distributed in various data centers , Communicate through the central server .

The cloud native database is based on Shared Everything + Shared Storage The storage and computing separation architecture based on is used to realize resource pooling and efficient management . And distributed , Just use Shared Nothing The architecture of , Achieve horizontal data fragmentation 、 Horizontal expansion . The two are combined , Its essence is to perfectly combine the characteristics of the three .

Xuzhijun, chairman in office of Huawei, also stressed that ：“ As cloud native applications penetrate into various business scenarios of the enterprise , Cloud native is moving towards distributed , Unified and collaborative governance across cloud and region , New requirements such as ensuring a consistent application experience are becoming increasingly prominent .”

According to the IDC forecast ,2025 year , Two thirds of enterprises will release software versions every day , Innovation and delivery through agile development capabilities , To form differentiated market competitiveness . In this business trend , Business and enterprise operation and maintenance need to rely on the database provided by the cloud native , Realize the value of intelligent upgrading , Fully release the dividend of Cloud Computing .

Tencent cloud native database TDSQL-C

Last month, ,Distributed Cloud｜2021 The global distributed cloud conference was held in Shanghai , Tencent cloud native database TDSQL-C Won the “ Cloud native superior technology provider ” prize ,TDSQL-C It is a cloud native distributed database developed by Tencent （ primary CynosDB）, Based on Shared storage , It has realized strong expansion ability and super million level QPS High throughput performance of .
