Zhang Xiaodan, chief architect of Alibaba cloud hybrid cloud: evolution and development of government enterprise hybrid cloud technology architecture

In recent days, , Zhangxiaodan, chief architect of Alibaba cloud hybrid cloud platform, shared IT Architecture Technology , It also looks forward to the development of the government enterprise hybrid cloud technology architecture .

Cloud computing has experienced more than ten years of development , Never thought of as “ Old wine in new bottles ” And was questioned , To be widely used in the field of consumer Internet , And then to the traditional government and enterprise customers' general recognition and rapid promotion in the field of government Internet business , At present, it has entered the tradition of comprehensively replacing government and enterprise customers IT The critical stage of infrastructure .

The so-called replacement , In China's government and enterprise market , It is based on the VPC & A unique cloud evolution path based on hybrid cloud and its extension scheme （ Non European and American public cloud extends the evolution path ）. In the past , Before Internet enterprises and small enterprises go to the public cloud , It mainly compares the technical product capabilities among public cloud manufacturers . however , Large and medium-sized government and enterprise customers go to the hybrid cloud , It is to comprehensively compare the technical product capabilities of hybrid cloud and traditional architecture .

Architectural technical insight

IT The architecture adapts to traditional applications from traditional platforms , Go back to the cloud platform to adapt to traditional and cloud applications

Tradition IT The architecture has passed through nearly 30 The development of , Form a data center characterized by hardware definition IT Infrastructure platform . These platforms are based on a variety of proprietary hardware systems , By system integrators and software ISV Do ecological support , Make customer application development focus on business logic , Various complex availability 、 Continuity 、 Extensibility 、 Security and other functions , Completed by differentiated hardware system （ Including proprietary OS And middleware ）. This stage , It's tradition IT The infrastructure adapts to the traditional application software stage .

The Internet business is developing rapidly , Promote the digital transformation of government and enterprise customers , cause IT The scale of software and hardware increases rapidly . Continue to support... With proprietary hardware systems and commercial software suites , Excessive investment in software and hardware , Supporting manpower also needs to increase linearly . So , Cloud architecture came into being . Various distributed microservice applications , Achieve more high availability directly at the software layer 、 Continuity 、 Extensibility 、 Security and other functions , No longer with IT Infrastructure is tightly coupled , Use a large number of common server systems and IaaS/PaaS Cloud platform replaces traditional mainframe / Small computer proprietary system . This stage , It is the stage for distributed applications to adapt to the cloud platform . At this stage, the investment in proprietary hardware system is greatly reduced , However, a large number of software development and operation personnel are required , Many customers do not have such conditions .

Development of cloud native technology architecture , Push IT The architecture returns to a higher-level cloud platform to adapt to cloud applications .

This stage is actually a deep foundation 、 The process of making thick middle platform . Software application architecture , To the business center 、 Data center 、 Low code platform 、 Collaborative platform development . The distributed microservice framework is becoming containerized 、Mesh、Serverless Development , The application deployment architecture is developing towards modularization, multiple locations and multiple activities . Database to HTAP Off line hybrid processing 、 Big data is integrated into Lake warehouse / Integrated development of flow and batch ,IT Infrastructure is integrated with hardware and software 、 Deposit is separate 、 Heterogeneous computing pool 、 Development of lightweight safety containers . Final , Make cloud applications lighter 、 Low coding , A large number of non functional requirements 、 Enterprise features , Even the code production is implemented by cloud platforms at all levels .

From a technical point of view , Cloud native architecture is a set of architecture principles and patterns based on cloud native technology , The purpose is to maximize the separation of non business code in cloud applications , So that cloud service providers CSP Cloud platform （ cloud IT Infrastructure and cloud application development and operation platform ） Take over a large number of non functional features in cloud applications （ Such as elasticity 、 toughness 、 Security 、 Observability 、 Gray scale, etc ）, Make the business no longer troubled by non functional business interruption , Light weight 、 agile 、 Highly automated features .

notes ： Generalized cloud native architecture = Cloud native technology + Cloud architecture principles + Cloud application architecture pattern + Cloud Applications + cloud IT Basics

Bimodal IT Applications will coexist for a long time , but IT Infrastructure needs to be consolidated into the whole stack faster IaaS cloud

At present , Cloud Architecture has been widely used in the Internet business of government and enterprise customers , But the main business management and core production application , Still running in traditional IT On the basic technology architecture . In the past 20-30 year , Government and enterprises have accumulated a large number of application systems with traditional centralized architecture . These application systems are difficult to be low-cost in the short and medium term 、 The whole ecosystem cooperates to reconstruct the cloud native architecture application , Customer 3%-5% Of IT Proportion of personnel , It is not enough to support such rapid refactoring and post transformation IaaS cloud , Most of them still run in the traditional IOE framework . With the Internet application of government and enterprises 、 Big data applications IaaS Behind the clouds , Customers need to maintain two sets of different end-to-end technology stacks at the same time .

Especially in the areas with the greatest pressure of operation and maintenance IT Infrastructure , Various closed systems based on traditional proprietary hardware , And software and service IaaS、DBaaS Such as system , In the technical architecture 、 Operation and maintenance methods 、 In terms of ecosystem , There are very big differences . Not accelerating the integration into the cloud platform , Not only can government and enterprises not reduce TCO, There are not enough resources to learn more about cloud architecture .

If the hybrid cloud IaaS+ platform （ Containing database 、 Big data platform ）, It can adapt to traditional applications at the same time 、 Cloud native applications and other mature cloud applications , It supports customers to step by step for some old applications 、 Internet applications will be put into the cloud after cloud native reconstruction , It also supports customers' understanding of traditional application code 、 Technical tools 、 Make a few cloud ready changes to the O & M organization system , Smooth migration to the cloud , Replace traditional centralized IT infrastructure , It can well support the comprehensive application of traditional government and enterprise applications to the cloud .

The products of cloud manufacturers replace the products of many traditional manufacturers , The aim is to create a higher experience cloud OS

Alibaba cloud's strategy is to build a deep foundation 、 Make a thick platform 、 Strengthen the ecology 、 Do a good job in service , Layer by layer IaaS/ PaaS/ DaaS/ SaaS Wait for cloud platform and cloud OS.

Do deep foundation , The essence is to develop software to define the data center and IaaS cloud OS. Software defines the data center , That is to regard the construction, operation and maintenance of the data center as a business , The process of this business 、 organization 、 personnel 、 Systematic data modeling of data , Then all business operations and data are encapsulated into services based on data modeling , Through layered nested service cloud platform and API Interface , Realize flexible arrangement and organization .

Make a thick platform , It is to continuously build a software definition development center and a business center OS、 The software defines the data management center and data center OS, Make the customer on our double stage , Can be low cost 、 Development, application and processing use data of high complex land . meanwhile , We will try to make the technology stack a layer of cloud OS And the lower clouds OS decoupling , So that it has the ability to flexibly adapt to the heterogeneous and cloudy lower layer of customers IaaS platform .

The reason why we want a cloud vendor to replace the original numerous computing 、 Storage 、 The Internet 、 Safety and other products , The purpose is to break the traditional closed proprietary software and hardware technology stack in each single vertical professional field , With the help of software, we can define the hierarchical and nested calculation in the data center 、 Storage 、 The Internet 、 Security database 、 Large databases and other service-oriented platform architectures , Use unified cloud platform software to manage and control scheduling capabilities , Integrate IT Infrastructure various standardized hardware resources , Provide flexibility on demand 、 Differentiation SLA Of IaaS service .

future , In every country and region, cloud computing market , There will be many full stacks IaaS The cloud manufacturer's products are used by government enterprise customers . These cloud vendors help customers do a good job in system integration and comprehensive services , It can not only reduce the overall TCO, It can also improve the comprehensive service experience . It's like open source Linux Wide application of products , It has replaced many original commercial basic operating systems , Not only did it not create a global market monopoly , It also helps customers lower the server OS Procurement costs for . Customers worry about the monopoly of suppliers , Meet the bidding procurement demand , Hope to introduce product technology competition , It is not suitable to use traditional “ parts ” Level decentralized competitive procurement 、 High cost self-assembly integration mode , It is appropriate to introduce full stack clouds from different cloud vendors to solve the problem on demand .

Customers pursue the black box experience of cloud products , We also need to have independent control over the cloud architecture

We buy and use a autonomous vehicle or smart phone , The aim is not to assemble flexibly 、 Disassemble and maintain the car or mobile phone , Instead, these products are black boxed, safe and stable 、 Simple and flexible control experience . The hybrid cloud product is a more complex one 、 Large enterprise platform system , But we also hope that our customers will get “ Manipulating a hybrid cloud is like manipulating a “ Autopilot ” The same experience , Send out various startup 、 brake 、 Route selection 、 Constant speed and other instructions and operations , Can be stable and reliable 、 Accurate and timely control experience , In addition, all kinds of sensitivity on the intelligent driving dashboard 、 accuracy 、 Comprehensive feedback , And a complete and effective emergency service system , It can enhance the confidence of customers .

At present , Hybrid cloud platforms are still in the process of development , It still relies heavily on cloud vendor services , Various fault emergency recovery operation platform tools are embedded 、 Quick start auto recovery capability , And self expansion and contraction / Upgrade and patch 、 Maintenance and change and other operation and maintenance capabilities need to be continuously improved . At this stage , We need to synchronize “ White box ” Open and transparent sharing of our cloud architecture construction concept and operation and maintenance experience , Listen to the front-line practice feedback from customers , Create, design and improve the cloud platform together “ Black box ” Service ability .

Public cloud and hybrid cloud architectures are both unified and different , From one-way ability transmission to mutual promotion

Most public cloud businesses of cloud manufacturers have experienced 10 The investment period is about years , With the help of large-scale applications of Internet customers , It has obtained the scale economy and shared economic dividends of the public cloud , Begin to tend to standardization and high efficiency , Entered a win-win stage with customers . However, the technology and management of the offline hybrid cloud market for government and enterprise customers are very different , The cost of offline delivery of decentralized operation and maintenance is very high .

for example ： It is only for the purpose of meeting the requirements of centralized measurement and quality control before the manufacturer , It is often necessary to invest 10000 physical servers , Build various heterogeneous multi-core systems 、 many Region Multi version cloud instance centralized test and verification environment for stock customers .

So , Only adhere to the unified core infrastructure of public cloud and hybrid cloud , To improve the internal R & D efficiency of cloud manufacturers , Share public cloud agile iterations 、 Bonus of grayscale verification . Public cloud and hybrid cloud develop independently , Insufficient R & D investment , It is easy to cause version dating for customers 、 Forced replacement and other problems .

however , Adhere to the consistency between the core infrastructure of public cloud and hybrid cloud , Does not mean that the public cloud will be large-scale 、 Distributed DevOps Build the software architecture and organization management mode mapped out by the operation and maintenance system and force them to customers , Instead, you need to target the hybrid cloud customer scenario , Comprehensively reconstruct the applications in the cloud management platform / Cloud products 、 Tenant / Cloud platform operation and maintenance system , Meet the needs of customers for comprehensive cloud deployment of traditional and cloud native applications and centralized construction, operation and maintenance management . meanwhile , We also hope that our customers can learn and master the principles and concepts of cloud architecture , Promote some organizational processes step by step 、 Supporting cloud transformation of the governance system , In order to give full play to the advantages of cloud architecture more efficiently .

Traditional applications of government and enterprise customers in different cloud maturity stages , It will coexist with highly mature cloud native applications for a long time . therefore , Yes IaaS Unified monitoring of cloud platform 、 Storage / Database intra city replication 、 Fault emergency recovery 、 Disaster recovery switch drill 、 Migration hot upgrade 、 Self expanding and shrinking capacity 、 Flexible backup and recovery 、 Unified security control 、 cloudy / Enterprise level features such as hybrid cloud management have high requirements . These enterprise level features are often built and perfected in the hybrid cloud environment first , In turn, it will promote the improvement of public cloud technology architecture and operation and maintenance capabilities , To lay a good foundation for supporting some business applications of government and enterprise customers in the future .

Government and enterprise customers focus on digital intelligence in the cloud / agile / economic , More attention is paid to security in the cloud / Self operation and maintenance

Initial stage of cloud computing represented by public cloud services , The main driving force for customers to go to the public cloud is to reduce costs and increase efficiency 、 Agility and flexibility . But in proprietary and hybrid cloud environments , Government and enterprise customers CIO What we care about , First of all, the whole country IT Continuous safe and stable operation of the system , It can recover quickly and autonomously after a fault occurs , And the substitution of self controlled product technology . The second is the introduction of big data 、AIoT Digital intelligence and technical ability , Promote innovative business development . Third , Is the pooled sharing of resources 、 Stretch and stretch , as well as TCO The fall of .

Agile independent research and development of cloud native applications of large Internet enterprises on the public cloud 、DevOps Integrated operation and maintenance 、 A large number of self-developed software tool platforms 、 Software management software best practices , It is not suitable for most government and enterprise customers with few staff 、 The ability of software self-study is weak 、 Application software is distributed, outsourced and customized 、 Software and hardware system integration and centralization IT Background characteristics of cloud environment such as governance and organizational management . So , The hybrid cloud platform needs to give priority to the construction and improvement of the high availability continuity design of cloud products , And Applications / Platform intelligent operation and maintenance capability , Give priority to ensuring the safe and stable operation of various mature Cloud Applications on the hybrid cloud , And the demand for independent and controllable construction, operation and maintenance , Consider the economy 、 Mathematical intelligence 、 Flexibility and agility .

Alibaba cloud hybrid cloud technology capacity building

Adhere to the consistency with the core technology architecture of the public cloud , Reuse public cloud dividends

these years , The core technology architecture of Alibaba cloud's hybrid cloud platform is consistent with that of the public cloud , Maximize the reuse of public cloud technology R & D practice dividends , It avoids the possible push down and restart of the branch of the product technology route , Maintain the stability of product technology architecture 、 Smooth upgrading and sustainable development . meanwhile , We are on a hybrid cloud platform , Increased research and development 20 About miniaturized minimum number of servers starting scheme , Various affinities 、 Non affinity and heterogeneous multi-core multi cluster scheduling strategy , Cloud products IAC Baseline mode final operation and maintenance and automatic thermal upgrading capability , To meet the differentiated needs of hybrid cloud customers different from public cloud customers .

Agile on the public cloud DevOps Accumulated experience in operation and maintenance , It also ensures the safe and stable operation of the hybrid cloud for many years , There have never been major technical route errors or unverified technical solution failures .

More than one cloud Region The architecture meets the cloud building needs of hybrid cloud customers

More than one cloud Region It is a cloud platform system using a set of user accounts and permission systems , The single user account has the permission to open the global resource instance 、 management 、 Application publishing capability .

Usually , Large institutions or enterprises have businesses all over the country or even the world , They often choose to build one in the group headquarters “ Proprietary cloud ”, Each functional organization under the headquarters needs to build its own Region. For this complex “ Total score type ” scene , More than one cloud Region Architecture can well support the business interconnection , Higher performance through large-scale deployment 、 More flexible workloads .

Why do you say “ More than one cloud Region” Than “ It's cloudy Region” Have more advantages ?

First, at the management level ：

• Unified planning and construction 、 operating 、 Operation and maintenance ;
• Have the ability of unified resource view and regional autonomy ;
• Have unified account and unified authority .

From a development perspective ：

• A development , many Region Deploy , Code can be managed centrally 、 Global distribution 、 Visit nearby ;
• Big data computing can unify the view 、 Cross domain computing ;
• It can support cross domain network connection ;
• It can support cross domain data flow .

From the perspective of elasticity and disaster recovery ：

• Support cross domain elasticity of applications , Maximize the use of resources ;
• It can support local disaster recovery and cross domain disaster recovery ;
• More than one cloud Region It is a kind of product disaster recovery capability , White screen management can be realized .

More than one cloud Region The architecture is mainly used to isolate the production and research environment 、 High security level internal network and external network are strongly isolated 、 Scenarios such as strong separation required by the compliance of different businesses of the group . These scenes pursue a high degree of isolation , Ask for each Region Have your own completely independent account permissions 、 Cloud management operation and maintenance 、 Run the safety management system .

The headquarters and provincial and municipal branches are government and enterprise customers of multi-level legal persons , If the multi cloud architecture is adopted , Need to be on a cloud , Rebuild a complex multi cloud management system , Achieve account single sign on 、 Unified authority management , Cloud management integration . Due to the lack of address allocation during the construction of each cloud 、 Unified planning of resource naming , There is no original integrated design for multiple independent control systems , It is difficult to provide customers with an integrated management experience 、 Flexible data sharing across domains .

Alibaba cloud hybrid cloud is physically dispersed 、 Logically unified “ More than one cloud Region” framework , It solves this problem very well , Unified user account authority system 、 The global view of resources is uniformly provisioned , The cross domain calculation of the big data of the total segment is particularly suitable for the government enterprise headquarters for the secondary subsidiaries “ It should be managed by the headquarters as a whole , And maintain the independent vitality of subsidiaries ” The needs of .

“ One cloud, many cores ” Support government and enterprise customers IT The autonomous and controllable strategy has evolved smoothly

IT Autonomous and controllable infrastructure , The hybrid cloud platform is required to be compatible with the mainstream fiveorsix heterogeneous chip servers in the market , This is compatible with the features of our cloud products 、 Online rotation upgrade 、 High performance tuning and scheduling capabilities are required , The workload of R & D, testing, deployment, operation and maintenance has increased more than ten times . After nearly two years of continuous investment , Make constant efforts to develop , Nearly 100 cloud products on Alibaba cloud's hybrid cloud platform , Most of them have realized single AZ Internal isomeric multi-core multi cluster hybrid unit , Some cloud products achieve the same structure of mixed parts with different cores in the cluster , A few products only support single cluster , It also realizes the mixing of products .

• Multi cluster mixed part ： When a customer applies to create a cloud product service instance , As long as you choose the heterogeneous chip type and manufacturer , The relevant service instances can be accurately created on the product cluster of the corresponding chip .
• Cluster internal mixing department ： When a customer applies to create a cloud service instance of a cloud product , Just choose x86 or ARM Chip type , There is no need to choose different manufacturers . During the batch replacement of servers in the cluster , The normal operation of the created cloud service instance on the cloud product is transparent . future , We will also further develop support within the cluster x86 and ARM Heterogeneous chip mixing part .
• Mix the department according to the product ： about AZ Only one cluster of cloud products can be deployed in , Customers can use a cloud instance , Select different chip types for deployment of these cloud products . Expansion of different chips in a single cluster / Replace , Priority should be given to solving problems through the cluster internal mixing department , Then, it is developed into multi cluster heterogeneous multi-core mixed distribution , And the short-time shutdown and migration of the whole cluster .

Industry Cloud / Government affairs cloud / The group cloud and other public cloud operation modes are becoming mature

In order to transform the service pattern 、 Optimize the industry ecology or increase the operating income , Some government and enterprises have the need to operate the industry cloud on the basis of the proprietary cloud platform , Turn your cloud into a cloud that can provide external services 、 Can be operated “ Industry Cloud ”.

Unlike the VPC , The customers of the industry cloud are divided into two layers , The first layer is the government and enterprises using the cloud platform , The second layer is the customers of government and enterprises . The existence and operation requirements of two-tier users , Need to be able to differentiate between platforms and tenants , Change the management of cloud platform from “ Operation and maintenance ” Dimension extends to “ operating ” dimension , At the same time, it continuously precipitates industrial solutions .

Alibaba cloud is based on its public cloud operation capabilities and experience , It has inherent advantages in the industry cloud field , Manage by providing service catalog 、 Process approval 、 Billing and operational efficiency , Large scale practices to help customers build industry clouds . Especially the billing capacity , We have abstracted and simplified the billing system based on Alibaba cloud public cloud , Make it better available to end users , Provide flexible and convenient charging rule setting capability .

meanwhile , We have enhanced the cloud platform “ Scalable ” Ability , For special operational sales 、 Business process demands , It can be expanded through annotation exchange , Together with Alibaba cloud's ecological partners , Provide functions that meet actual business needs , Better support the industry cloud operation of customers .

A cloud of provincial government affairs 、 Alibaba cloud, a financial institution, industry cloud and other leading enterprises in the industry and government departments jointly invest in 、 Share business risks , The revenue sharing operation mode has been successfully operated for many years , Focus on the follow-up industries of the domestic hybrid cloud market 、 Regional concentration 、 The national / The provincial centralized industry cloud construction trend has accumulated a lot of meaningful experience . for example ： A provincial government affairs cloud pilot operation “ More than one cloud Region framework , It has been well promoted in the subsequent central enterprise customers of a large group . Cloud multi tenancy of a financial institution IaaS Cloud platform services , Safe and stable operation for more than three years , Trading application for small securities companies and financial institutions 、 The developed disaster recovery application provides good support for comprehensive cloud deployment .

Soft and hard integration 、 The separation of storage and computing creates a cloud native database

In the past 30 year , Government and enterprise customers rely on the traditional integration of software and hardware 、 Separate deposit and settlement “IOE” Centralized database architecture , Support and guarantee the construction and development of the customer's core business system , With the development of Internet business , The amount of data is increasing dramatically , The database is gradually changing from Shared Mem/Disk Centralized architecture for , towards Shared Nothing Distributed architecture evolution .Shared Nothing Distributed architecture database requires distributed transformation of application architecture , It is difficult for customers to quickly and comprehensively restructure all traditional applications .

A large number of traditional applications are still in use x86 Active / standby of the local disk of the physical machine /3 Open source of node election /RDS MySQL database . However, the architecture of computing and storage coupling can not play the role of cloud computing resource pooling 、 Elastic expansion and contraction 、 Advantages brought by technological dividends such as agile supply , The storage capacity of a single database is less than 6T,QPS/TPS Co., LTD. .

With DPCA based servers +25G The Internet +CDS The software and hardware of the distributed shared cloud disk 、 The separation of storage and computing is becoming more and more mature , Alibaba cloud hybrid cloud 2022 Will be launched in based on DPCA CDS、 Containerization 、Shared Everything Architecturally PolarDB O Shared storage database , It can provide highly compatible services for government and enterprise customers Oracle Syntax database engine , All database instance computing nodes share one data 1 Write 15 read （ Writing and reading more is in the process of research ）、100T Storage & 100 ten thousand QPS A large centralized library , And online agile elastic scaling 、 Flexible snapshot backup and recovery 、 Compute node failover RPO=0 And RTO<15s High availability 、 Enterprise level features such as separate pooling and sharing of computing storage resources , Meet the traditional application system of government and enterprise customers without distributed transformation , Can also IaaS The need to move to the cloud .
