[Cloud Technology] How do medium and large-scale enterprises deploy multiple data centers?

Introduction to With the acceleration of the modernization process, the scale of enterprise business and the speed of iteration are not what it used to be. In the medium and large power systems that have a certain scale, they will face the pressure of digital upgrade, including complex organizational structure management, computing resources Flexible expansion, IT operation and maintenance efficiency and other requirements. Deploy an industry-specific cloud based on the attributes of the power industry. This cloud not only has the security and stability characteristics of localized deployment of proprietary clouds, but also enjoys the flexibility of public cloud to use cloud services on demand and pay for usage. But when it comes to large-scale or cross-regional cloud platform deployment scenarios, deploying services in different regions and data centers will face many problems. How does Alibaba Cloud Hybrid Cloud use the region logic of the proprietary cloud to form a multi-region architecture + hybrid cloud multi-cloud management platform capability, so as to realize the deployment of a proprietary cloud in multiple regions and solve the problem of large-scale users and multi-data center deployment problem?

Japanese director Yaguchi Shiyasu once filmed a self-disaster comedy film "Survival Family", which tells the story of a sudden global power outage, all electric tools stopped working, and an ordinary family fled from Tokyo to Kagoshima in order to survive. . Although the performance is slightly exaggerated, the shutdown of the world without electricity is impressive. Electricity has become an important industry deeply bound to human society.

As the center of electric energy production and consumption, the electric power system involves complex network links of power generation, transmission, transformation, distribution and power consumption. In order to support this complex system, the power system also has corresponding information and control systems in each link to measure, regulate, control, protect, communicate and dispatch the electric energy production process to ensure that users receive safe and high-quality electric energy at all times. .

In traditional power companies, the old "chimney-style" construction architecture model is still the majority. Information and control systems operate independently, data standards are not unified, and decentralized construction and management have led to the formation of "data islands". Great waste of human and physical resources.

At the same time, with the acceleration of the modernization process, the scale of enterprise business and the speed of iteration are not what it used to be. In the medium and large power systems that have a certain scale, they will face the pressure of digital upgrade, including the management of complex organizational structures and the elastic expansion of computing resources. , IT operation and maintenance efficiency and other requirements.

The current common practice is to deploy an industry-specific cloud based on the attributes of the power industry. This cloud not only has the security and stability characteristics of localized deployment of proprietary clouds, but also enjoys public cloud on-demand use of cloud services and pay-per-use Flexibility. However, in the process of use, large-scale or cross-regional cloud platform deployment scenarios are often involved. The deployment of services in different regions and data centers will face the following problems:
1. How to manage cloud resources in different regions in a unified way, and match the distribution of permissions with the actual usage scenarios and organizational structure of users;
2. The guarantee of high availability. When a data center fails or a disaster occurs, other data centers can normally provide services to the outside world;
3. Compliance requirements, the unified management and authority allocation of multiple data centers need to comply with the user's internal regulations, as well as the requirements of laws and regulations;
4. The access of many applications or businesses needs to work together across multiple data centers, how to realize the linkage and sharing of resources between each data center;

Alibaba Cloud Hybrid Cloud uses the region logic of the proprietary cloud to form a multi-region architecture + hybrid cloud multi-cloud management platform capabilities, so as to realize the deployment of a proprietary cloud in multiple regions and solve the problem of large-scale user deployment in multiple data centers.

The proprietary cloud region (Region) is divided into a central region and a normal region in terms of architecture design. Proprietary Cloud Multi Region has the following characteristics:
• One cloud, providing unified management and control, unified operation and maintenance, and unified monitoring capabilities.
• Consistency, consistent with the architecture of Alibaba Public Cloud.
• Compatibility, forward compatible with the deployment form of a single region, and backward support for the expansion deployment of multiple regions.
• Availability, fault domain isolation, when the central Region fails, it does not affect the use of cloud instance resources that the cloud platform has applied for. When a problem occurs in a common region, it does not affect the use of other regions.

The multi-region architecture focuses on the unification of cloud management and control levels, with a single center for unified management, unified operation and maintenance, and unified measurement.

The read and write services of basic services are deployed in the center, and the basic services of ordinary regions only need to deploy service nodes and provide read services, and the central region will uniformly manage, control, operate and maintain.

Unified management, control, operation and maintenance in the central region. The Aliyun hybrid cloud management platform (Apsara Uni-manager) can effectively manage multiple regions. The hybrid cloud management platform is committed to creating a unified cloud management portal for enterprises with thousands of people and personalized experience. , Carry out global intelligent optimization from applications, cloud resources, hardware, etc., to achieve the best ratio of resource allocation and intelligent risk early warning capabilities, provide customers with intelligent command with integrated supervision and control, and empower corporate business.

Faced with the management of complex organizational structures in large power systems, the central Region can be regarded as the headquarters of the organization, and the hybrid cloud management platform is the intelligent commander stationed in the headquarters. It mainly adopts a decentralized and domain-based management model. At the level of cloud resource use and maintenance, administrators with a regional resource management authority can only manage the equipment and use related functions in their own jurisdiction, but cannot manage resources in other regions. And equipment. At the business and data configuration level, the administrators of each management area also only need to pay attention to the business and data resources in the area, and cannot view or modify the resources in other areas without authorization.

Through the hybrid cloud management platform, a sub-domain collaboration mode under centralized management is formed, so that the central region and ordinary regions are constructed on a provincial basis, cross-local network deployment, resource sharing, and collaborative management, saving supporting investment.

At the same time, applying the flexible switching and configuration capabilities of Region centralized management or edge Region autonomous management can make maintenance management more flexible, make full use of regional operation and maintenance resources, improve regional operation and maintenance efficiency, and reduce product use and operation in the region where the central region is located. Maintenance pressure to optimize the operation and maintenance process of cross-regional collaboration.

At present, Alibaba Cloud Hybrid Cloud has served a number of leading companies in the power industry through a multi-region architecture + hybrid cloud multi-cloud management platform solution. For example, it has helped China Southern Power Grid build the industry’s first dispatch automation system platform based entirely on new Internet technologies. The cloudification and migration of 76 sets of dispatching systems saved hundreds of millions of dollars in overall construction costs. The cloud-based SCADA system processes more than 60,000 messages per second. The whole system is deployed in 70 seconds with one key and quickly expands in 10 seconds. The AI accuracy rate of day-ahead load forecasting is as high as 97%, exceeding the level of manual forecasting.

As a necessary part of the national economy and people’s livelihood, electricity consumption has now put forward higher requirements for the digitization, automation and intelligence of the power system. Alibaba Cloud Hybrid Cloud is committed to promoting data collection and transmission in power generation, transmission and distribution, and power consumption and dispatch. , Storage and utilization capabilities, which in turn automates the business processing of the enterprise, the informationization of business management, and the scientificalization of strategic decision-making.

Note:
cloud region (Region) refers to the collection of infrastructure services in a certain region as a region based on geographic location. Each area is independent of each other and can be divided according to multiple dimensions, usually according to the city where the data center is located. The proprietary cloud service deploys various applications based on the geographical location of the area; it can also be divided according to compliance requirements and can be divided according to different choices. The area stores data to meet regulatory compliance requirements.
