Recently, the 6th Shanghai Artificial Intelligence Conference Spring Forum came to a successful conclusion. With the theme of "Digital Intelligence Facing the Future", the conference invited top scholars from academia and technological experts from countries and regions at home and abroad to discuss the research, talent, technology of artificial intelligence and the difficulties of industry development. As a basic software in the era of digital intelligence transformation, AntDB was invited to participate in this conference, and its technical leader Bei Mo delivered a speech on "AntDB helps financial/telecom carriers upgrade and transform their core transaction system" in the "Smart Finance" forum. From theories to practices, the keynote speech showed the path and feasible solutions of core transaction system upgrade and transformation in all aspects.

The difficulties of core transaction system upgrade and transformation

In the times of digital intelligence transformation and continuous development of new technologies such as artificial intelligence and meta-universe, all industries have ushered in new development opportunities and challenges. Database, as one of the basic software, is the base for digital intelligence transformation and the basic technology supporting the development of new technologies such as artificial intelligence. The core transaction system is vital to the IT system in the financial and telecom industries, and is a key factor affecting the success of the transformation of these industries.

As the core transaction system, in terms of database performance, relies on the original library in traditional centralized deployment, the limit of connection number, disk operations and other characteristics, it has difficulty in large-batch concurrent processing and improving the performance; in capacity expansion, the license cost is too high according to the number of instances / CPU, which can not adapt to new business needs. Therefore, the transformation of IT core system into distributed architecture is imperative.

AntDB boost the upgrade and transformation of core transaction system of finance and telecom industries

The general direction of database evolution is to evolve to distributed architecture through technological innovation and X86. Distributed databases are used to solve the horizontal expansion of database, and combine with business scenarios to complete the upgrade and transformation of core system.

AntDB is a product born to meet the request of carriers at the beginning of the 21st century when foreign brand databases could not meet the globally rare demand of ultra-high frequency and ultra-high concurrent communication data management in China. From the first generation of fully self-developed in-memory database to the current distributed streaming real-time data warehouse widely compatible with SQL ecology, after 15 years of refining in the core business of telecommunications, it has formed four features:

• Amount - A huge number of subscribers. More than 1 billion mobile the phone owners using AntDB database in the background.

• History - A history of solid implementation. It has been applied in the core billing system of telecomm carriers since 2008, and has experienced 15 years of careful refinement.

• Speed - Fast execution performance. AntDB can handle millions of core telecom transactions per second at its peak.

• Stability - A stable and reliable product. It has been running stably in the core system of telecom carriers for 15 years.

So, what are the advantages of AntDB as a general-purpose enterprise-class relational database in the upgrade of core transaction systems in finance and telecom industries?

Firstly, the stability and security have been proven trusted in the core business systems of carriers for many years;

Secondly, multi-tenancy capability isolates database instances from logical layer to physical layer to ensure no interference between services and flexible scheduling of underlying computing and storage resources for sudden business peaks;

Thirdly, AntDB hyper-converged database provides built-in data processing pipeline, so that the data processing plane and business operation plane are independent of each other and do not interfere with each other, and the real-time data processing is guaranteed;

Fourthly, the built-in data lifecycle management system automatically isolates hot transaction data from warm and cold ones, and the computing and storage engine automatically optimizes the selection.

Fifthly, it relies on the AIOps engine to empower the system operation and maintenance with intelligence.

Most importantly, AntDB has helped many customers in telecom, transportation, finance and other industries to realize the upgrade of core transaction system, and the products and service capabilities have been recognized and praised by many customers.

Core transaction system upgrade and transformation solution

The technical director of AntDB, Bei Mo, shared the case of AntDB helping to upgrade and transform the core transaction system of telecom and finance industries.

Firstly, he introduced that AntDB helped a customer in the telecom industry to make breakthrough progress and complete the "first" migration of data of core accounting database in the country. The highlights of the case are mainly reflected in the Raft-based highly available architecture, smooth expansion and performance improvement: the overall efficiency of key business processing is improved by 10%, the overall time of accounting processing is shortened by 1/3, and the online dynamic expansion of data slice is completed within hours with no transaction interruption.

After that, he introduced the application of AntDB in the massive detailed ticket library and the upgrade of a provincial CRM core system of China Mobile. In the massive detailed ticket library, AntDB stores the call records of about ten million mobile phone users, involving billing, detail ticket query and statistics. The application highlights here are mainly in the following two aspects: AntDB adopts distributed dual-center deployment architecture, compared with the original four-node RAC, the performance is greatly improved and the cost savings is nearly 80%; the massive storage platform is designed with a capacity of hundreds of terabytes, billions of records are added every day, and the database stores 3+1 months of data in a cycle. A provincial CRM core system of China Mobile adopted applications of architectural innovation, read-write splitting, micro-library, to achieve low-cost, low-risk business replacement of the way to achieve Oracle/AntDB heterogeneous dual-plane database to ensure business continuity.

Finally, the case of AntDB in a big data platform of a life insurance company in the north is shared: the solution adopts distributed database, which included high availability configuration with one master and one slave database, and makes full use of the function of analysis and calculation of AntDB to deploy the big data platform. For the complex big data query, calculation, table association and other scenario requirements, AntDB highly available distributed database proved its OLAP capability and helps the big data platform to complete the upgrade.

AntDB can perceive the scenario changes brought by technological development and can conduct technological innovation with future-oriented insight because it has been serving the telecom carriers who are closest to technological changes. The hyper-converged streaming real-time data warehouse of AntDB version 7.2 integrates multiple engines and capabilities in the overall architecture to meet the increasingly complex business needs of enterprises for mixed loads and mixed data types; through the cloud-native "streaming real-time data warehouse engine", streaming computing and database are integrated and innovated from the kernel level. It can meet the needs of real-time processing scenarios such as real-time business analysis and real-time reporting, as well as the needs of asynchronous transaction scenarios such as Internet+. We believe that with the further development of digital intelligence, AntDB will integrate and innovate more new technologies with database according to the needs of future scenarios to help enterprises better meet future challenges.
