China Airlines letter Li Huewei: Cloud computing Three steps business intelligence analysis and coping with Big Data era

Aviation Letter Air Information Group was formally established in October 2002, its predecessor is the CAAC computer room. Listed in Hong Kong in February 2001, after eight or nine years of development of the global existing staff of nearly 4,000 people. Li Huewei of China Civil Aviation Information Network Corporation outsourcing service Support department in the CCS Cloud Computing Summit Forum introduced, the aviation letter already has 30 years of service experience, is the central enterprise only engages in the information Service enterprise, this also lets the aviation letter the mission and the social responsibility to strengthen.

Aviation Letter It Construction

Aviation letter is the air travel industry's information technology and business service providers, a total of 7 major business areas. The platform currently handles more than 11,000 TPS per second, with an average daily passenger volume exceeding 1 million and a daily turnover of more than 1 billion yuan. Li Huewei said it would take more than 2000 hardware devices to support large-scale transactions, including network devices, storage devices, computing resources, and so on.

And, the letter has more than two PB of storage, more than 17000 of the network and optical access ports, hardware resources, the average utilization of more than 62%. These hardware resources are distributed in the East Four, also Zhuang, three Li Tun three data centers.

As the leading information service provider in the Aviation field, the first choice of the aircraft is the big machine platform, after 20 years of operation, to 1995, 1996 found some drawbacks. Li Huewei points out that as the business continues to evolve, we find that the entire platform is closed, the complexity of management is not easy to expand, unlike today's popular open systems, so our managers need specialized knowledge for software development and business development.

Li Huewei introduced that in 1995, developers for the mainframe at the bottom of the source code analysis, independent development of a set of interfaces, aviation letter to the entire mainframe migration, the core business functions migrated to the open platform.

Three steps to cloud computing

In 2006, the aviation letter began to touch on virtualization technology, using virtualization to improve application usage and reduce the use of computer room and power. It started migrating to X86 and virtualization platforms in 2008, and the entire migration process involved nearly 60 businesses, which took nearly a year. The virtualized data center of the migrated avionics includes not only the virtual machine, but also many X86 physical entity machines.

"So far, 90% of the data in the database is not running in the virtualization platform, 20% of the database running on the X86 server, in the future want to be able to migrate all resources to the virtualization platform." "Li Huewei points out.

In addition to virtual outside the Air China letter also developed its own cloud computing development blueprint. It is divided into three steps: Virtualization, virtualization, cloud computing. Li Huewei pointed out that as the first step achieved good results, we also found some management problems, especially for this configuration management. From 2009 to now, the aviation letter has been doing the whole platform optimization and improvement work.

Roadmap for the development of China's virtual infrastructure for navigation letters

For today's three cloud computing models, the airline has chosen a relatively secure private cloud model, and is planning to build an industry platform.

Li Huewei that virtualization is only a part of cloud computing, virtualization is a physical machine to meet a number of small logic machines for different services, while in the Data Warehouse platform is an OLAP system, so the parallel processing capacity is more important, this is the cloud itself a technology.

Business intelligence analysis and coping with large data age

2002 Air Passenger volume breakthrough 100 million, which means that the aviation letter is facing the growth of massive data, the aviation letter set up its own data Warehouse intelligence analysis platform. As the number of growth, also reflects the data load cycle is growing.

The Civil Aviation Authority forecasts that the 2020 air passenger volume will exceed 700 million, the aviation letter must face the Internet Data diversity request, the massive data, the unstructured data processing. And in the intelligent analysis requires rapid response, in the face of these challenges the letter has developed a large data development plan to X86 as a traditional data processing platform for unstructured data will be full open source and X86 low-cost solutions.

It is reported that the future framework of aviation letter is static data and structured data coexistence, reliance on reliability, manageability characteristics of customized development of business intelligence system tools. For unstructured data, the intelligent Analysis platform is developed in a flexible, customizable and distributed way.

Li Huewei finally concluded that, regardless of the route of the virtual road, or large data thinking, are derived from the demand. Most of the applications and technological changes come from the needs of their own or the customers ' industry. In the private cloud, do not cloud for the cloud, and blindly implement some applications will outweigh the loss, the aviation letter also traversed a similar detour, so must be from the needs of their own enterprises to consider.
