At 7 o'clock in the evening on July 26, 1882, 15 arc photoelectric lamps connected in series on the 6.4-kilometer power supply line on the Bund lighted up. On this day, China's power industry started from Shanghai. For more than 100 years, China's power industry has achieved leapfrog development, and the 3 trillion power empire, the State Grid, has now become the world's largest utility company. In the 21st century, the digital economy has become a new battleground great power game, carrying electricity as a basic hub of the country's energy industry, entered the ranks of global competition. Unfortunately, standing at the door of digital transformation, China's power industry has been slow to enter.
In recent years, only a few power companies have achieved cloud business on the edge, and many power companies have even seen a "bad tail" project on the cloud. Where is the difficulty in the digital transformation of the traditional power industry? The power industry experienced digital transformation
"Mirror Flower Moon"?
Over the past 20 years, Oracle databases, minicomputers, and centralized storage have been basically the “standard configuration” of the IT infrastructure of domestic power companies. As the system equipment ages, the performance of this "chimney" IT architecture becomes increasingly degraded.
In addition, power companies often use industry-specific software and hardware systems, and the complexity of system integration is high, which means that the system cannot be upgraded and expanded on a large scale, not to mention docking with new technologies applied by upper-layer applications.
How to implement a new generation of IT infrastructure to support digital services on the basis of maintaining stable operation of IT systems has become a core challenge facing the current power industry transformation.
At the same time, China has a vast territory and IT levels vary greatly in different regions. Many power companies in second- and third-tier cities do not have IT talent in first-tier cities. The rapid iteration of new technologies and the operation and maintenance of IT systems have made power companies feel pressured.
Taking IT operation and maintenance as an example, as the technology used by the old system gradually withdraws from the market, power companies cannot obtain corresponding maintenance support from the original manufacturer. Without technical transformation or daily operation and maintenance by corresponding technical personnel, once the system In the event of a collapse, the electricity business of enterprises and ordinary people will not be guaranteed.
It must be said that domestic power companies are burdened with excessively heavy historical burdens. The road of IT system transformation is full of hardships and challenges. Without industry successful experience to refer to, the digital transformation of the entire power industry is like a mist and difficult.
Is the digital transformation of the vigorous power industry really a "mirror month", or "getting the fog and seeing the moon"?
Cloud was born "model room" on the first core business
In 2016, the State Grid ushered in the beginning of the "13th Five-Year Plan", in which the integrated "State Grid Cloud" platform was the highlight of the State Grid's core informatization construction. After three years of exploration, the domestic power industry has finally heard good news: the first power company that successfully launched its core business in the cloud was born!
At the end of 2019, State Grid Heilongjiang Electric Power Co., Ltd. (hereinafter referred to as Heilongjiang Electric Power) relied on Qingyun's QingCloud cloud platform and QingStor® NeonSAN® integrated solution to migrate its core business system ERP to the cloud. So far, its marketing system, network management system, office system, ERP system and other core business systems have all been migrated to the cloud.
Like the national subsidiaries of State Grid Power, Heilongjiang Power has always faced the rigidity of the traditional "chimney" IT architecture, the aging of the ERP system, the decline in performance, the complexity of the Oracle custom database, the inability to expand, and the obsolescence of equipment and lack of vendor maintenance Problem, the migration of core business to the cloud is very difficult. However, not only successfully achieved Heilongjiang Electric Power IT infrastructure transformation, also received the full support of the operation and the operation and maintenance of the core business, to create a cloud-level textbook on the core business of "Open House", the IT transformation called "hard core ":
In terms of architecture upgrades, the migration from the minicomputer to the x86 open architecture has been carried out, and the entire core business has been cloudized, which has greatly improved the ability to continue operations.
In terms of performance improvement, a high-availability, high-performance distributed data storage platform is built, and Oracle database performance has been improved by more than 10 times in multiple dimensions compared to previous architectures.
In terms of cost reduction, the cost of x86 general equipment is significantly lower than that of special customized equipment, and the overall cost of supporting spare parts and operation and maintenance personnel is also reduced.
In terms of operation and maintenance convenience, all the middleware of SAP is deployed on Qingyun QingCloud cloud platform, which has acquired the ability of the cloud platform itself to be automated and easy to maintain and expand. The Oracle database is deployed in the form of a physical host, which is easier to maintain than a small computer, and the difficulty of spare parts procurement and daily operation and maintenance is greatly reduced.
In terms of business support, relying on Qingyun's QingCloud cloud platform, resource allocation is more flexible and flexible, data utilization is more centralized and intelligent, service integration is more unified and efficient, application development is faster and more convenient, and comprehensively improve the IT architecture's ability to support various businesses during the digital transformation stage .
From the perspective of the national power industry, the power of Heilongjiang Power is not large, and IT investment is not high, but it is the digital pioneer in the power industry that first "eats crabs" and then successfully "breaks the situation." What is the reason?
In fact, Heilongjiang Power is one of the earliest power companies in the industry to try to build a cloud platform, and its technological innovation capability ranks in the forefront of the national subsidiary of State Grid.
According to the person in charge of the informationization of Heilongjiang Electric Power, "information reform is hard work and good at spending limited money on the blade." As early as 2016, Heilongjiang Power Cloud Platform adopted multi-cloud heterogeneity, merged and managed the State Grid Cloud 1.0, OpenStack and other platforms, and successfully launched the test system to the cloud.
However, with the increase in business volume and Internet business needs, Heilongjiang Power also encountered a bottleneck when using the OpenStack cloud platform: based on the open source properties of OpenStack, the underlying system and storage are not stable enough for large-scale deployment, and the versions are frequently upgraded We have to fix bugs again, making it difficult to carry the core business system of power companies.
This is undoubtedly an important point for transformation and upgrading for Heilongjiang Electric Power, which hopes to seize the opportunities of digital transformation and enhance its core competitiveness.
How to migrate a large number of core businesses to the cloud to ensure capacity expansion on the cloud, and at the same time data exchange and related extensions with new Internet services, has become a new challenge facing Heilongjiang Electric Power.
So, how does Heilongjiang Power, which has an old and complicated IT system and a limited budget, successfully "break the game"? State Grid Heilongjiang Electric Power "hard core" IT transformation
Carefully analyzing the existing IT architecture of Heilongjiang Electric Power, there are actually two major flaws:
One is that the SAP architecture of the ERP system is old, each component is in a tightly coupled state, and the system performance is low.
Second, the hardware architecture is specially customized, which is costly and not easy to expand.
In fact, to realize the upgrade and transformation of the ERP system, migrating the new generation of data architecture from the minicomputer to the x86 open platform is not only a technical task, but also a complex project with no details.
If you don't know enough about the original IT system, SAP and Oracle technologies, the migration to the cloud will be very difficult. This puts higher requirements on cloud computing vendors' resource allocation, diagnostic consulting, program formulation, and risk control capabilities.
In response to the IT system transformation needs of State Grid Heilongjiang Electric Power, its cloud computing partner Qingyun QingCloud implemented detailed diagnosis and consultation:
First, for the SAP architecture, Qingyun QingCloud has been adjusted to re-separate the components in the original system that are tightly coupled. HA (High Available, availability) after switching when the split long been significantly improved, in about 10 minutes when the length of the original handover, the HA of the new architecture in the switching time of about 1 minute.
This split deploys the main components of the system separately, which improves the stability of the entire system. It does not occur that the system is overloaded due to business growth and loses response to the front end.
Second, the hardware architecture, Qingyun QingCloud renovation work will be divided into two: one is to build an open architecture, which uses cloud services and universal x86 servers, building an open architecture, instead of the original architectural design of proprietary hardware. In this way, there is no need to purchase new proprietary hardware equipment, which greatly reduces the IT procurement cost of the enterprise and the difficulty of subsequent upgrade and maintenance.
The second is the use of distributed storage, that is, distributed storage QingStor® NeonSAN® as the core storage platform, replacing the original dedicated centralized storage, which helps to completely break the bottleneck of current centralized storage in terms of performance and scalability.
Taking single-volume performance as an example, the traditional mechanical disk single-volume IOPS generally does not exceed 200, while QingStor® NeonSAN® distributed storage can achieve a single-volume 100,000 IOPS, and the performance is improved by about 500 times. As the number of distributed cluster nodes increases, the performance and capacity of the entire distributed storage will increase accordingly.
At the same time, the multi-copy and strong consistency mechanism of QingStor® NeonSAN® can improve the reliability of data as a whole, and can effectively avoid the deterioration of read and write performance and even unavailability caused by node hard disk failure.
It is worth mentioning that the reason why QingStor® NeonSAN® performs so well is thanks to Intel® Optane ™ technology, which provides better system efficiency and higher reliability.
Intel® Optane ™ DC SSDs are very different from traditional NAND SSDs. NAND solid-state disks have inconsistent size units for reading, writing, and erasing, and they need to be erased before writing to write.
However, Intel® Optane ™ media can be addressed in bits, and the read and write units can be defined in almost any size. At the same time, almost no junk data is generated, and the read and write efficiency is higher.
In hybrid read-write applications, the read latency of Intel® Optane ™ SSDs is almost unaffected by write operations, and this improvement in read-sensitive applications is revolutionary. At the same time, the improvement of Intel® Optane ™ media can make the entire disk write times reach 60, and the durability is more powerful.
Based on the blessing of the above two features, in the field of cache applications, the lower capacity Intel® Optane ™ can be used to achieve the effect of larger capacity and high performance NAND SSD.
Therefore, Intel® Optane ™ can provide a series of capabilities for accelerating the core business, including: metadata storage, temporary copy and hot data storage, hot data cooling migration, etc., providing more capacity for the core business in multiple ways , Faster storage capacity with lower latency. Considering Heilongjiang Electric Power is the first attempt to cloud ERP core business, IT infrastructure and large-scale transformation, under the important task is even more rigorous planning and steadily push forward.
In this regard, Qingyun QingCloud not only provides a detailed ERP cloud solution, but also provides a complete ERP migration and test solution, creating a complete set of "diagnosis consulting-migration testing-steady cloud" core business cloud service solution .
Before the official migration, Qingyun QingCloud first carried out a PoC environment simulation by building a sandbox environment, and then performed a migration simulation to record the migration steps, time-consuming, and unexpected problems. Finally, in accordance with the set sequence and step markers, the development system environment is switched and the production system environment is migrated, thereby completing the entire ERP production environment migration.
In order to minimize the risk in actual use, Qingyun QingCloud even simulated extreme conditions such as "destructive power failure" for testing. Facts have proved that Qingyun QingCloud still guarantees the continuity of the core business in the event of a sudden power failure, and will not cause data loss.
Qingyun QingCloud's complete set of service plans has fundamentally dispelled the doubts of Heilongjiang Electric Power. Eating the “Dingxin Pill” of Heilongjiang Power, thus steadily starting the “hard core” IT transformation journey, providing a model room for the core business of the traditional power industry, Shangyun.
There is a shortcut to the core business of the power industry
It is worth noting that in the power industry where digital transformation is generally difficult, can this job in the cloud business of Heilongjiang Power be directly copied?
According to incomplete statistics, 90% of the company's core business systems are based on database development. The database system represented by Oracle is recognized as the core of the enterprise IT system and has a wide range of users in banking, securities, insurance, energy, medical and other industries basis. This traditional IT architecture is exactly the same as Heilongjiang Power.
In other words, the solution cooperated by Heilongjiang Electric Power and Qingyun QingCloud is not only applicable to the power industry, but also applicable to other industries that are limited by "traditional centralized IT architecture and Oracle database".
From the perspective of application practice, Qingyun QingCloud "Oracle solution based on distributed storage" has already landed in many industries such as energy, finance, Internet of Things, education, medical care, retail, transportation and other industries, helping traditional enterprises to achieve cloud-based upgrade of core businesses In terms of, it has a very strong application.
It can be said that this solution has become an ideal shortcut for the traditional enterprise's core business to go to the cloud.
The reason is that Qingyun QingCloud is not only a leading large-scale cloud service provider in China, but also has rich industry experience. It can start from the actual business needs of customers and IT level, and use professional technology and services to support enterprises to steadily go to the cloud. .
Qingyun QingCloud has been unanimously recognized by the industry in terms of stability, scalability, and large-scale hosting of cloud architecture.
