K8S application cluster solution

• With the advancement of the construction of the bank's new-generation informatization operation and maintenance system, the speed of application system upgrading has increased significantly. The development of digital transformation has put forward higher and higher requirements for the agility of banking business needs, and it has become a general trend to promote agile development and agile deployment of resources.

• 
  

• background

• 
  

• A rural commercial bank in Jiangsu was established on November 27, 2001. It was the first rural commercial bank restructured from a rural credit cooperative in the country. The bank gave full play to its typical exemplary role as the “first mover in rural finance in China”, continuously deepened financial innovation, and steadily promoted business transformation, setting a number of “firsts” in the history of the development of rural commercial banks across the country. It has gradually become a regional commercial bank with strong core competitiveness.

• 
  

• "Science and Technology Leadership" is one of the important development strategies of the rural commercial bank. It insists on formulating IT development plans systematically and scientifically, and has achieved great results in the information operation and maintenance system. Not only has it accumulated a large amount of basic software and hardware resources in the basic environment, and has formed strong support for business departments; it has also promoted the establishment and implementation of a management mechanism for the entire operation and maintenance process through the formulation of a series of operation and maintenance-related technologies and quality standards. In terms of maintenance team building, a normalized interactive linkage mechanism has been formed.

• Focusing on the goal of promoting management uniformity, efficiency, coordination and safety, the rural commercial bank has joined hands with Suoxiang Technology to unify planning and promotion of the goals from the four aspects of safety, resource intensive, process control, efficiency and quality, and build a unified research and development. Support the cloud environment.

•  challenge

• 
  

• From the perspective of the overall operation and maintenance of the rural commercial bank, there are still difficulties and pain points in operation and maintenance:

• 
  

• solution

• In order to solve the current difficulties in the operation and maintenance of the rural commercial bank, Boyun built a "development and testing cloud management platform" according to its business needs:

• 01 IaaS platform construction

• 
  

• The bottom layer adopts the mainstream open source OpenStack+Ceph IaaS solution technology solution. At the same time, Boyun implements optimization functions such as performance optimization, IO path optimization, and virtualization stability improvement for native technology, which improves the utilization rate of development and testing virtualization, and improves business coverage and development resources. Gain experience to better support the innovation and development of Internet financial services.

  01	Improve R&D efficiency and quality, and realize business value

  02	Standardize management, improve management efficiency

  03	Save project cost and improve economic efficiency

  Based on the pain points of the rural commercial bank's overall operation and maintenance level, and based on the characteristics of its IT system architecture and business scenarios, a set of safe, reliable, and compliant development and testing cloud management platform solutions were tailored to achieve flexible resource allocation. Improve resource utilization and save costs, thereby promoting the rapid development of corporate business and benefits.

• Hardware resource sharing, flexible recycling, avoiding resource waste to the maximum extent;

• 
  

• Unified management of all server operation and maintenance work, further optimize the infrastructure operation and maintenance support team, and reduce operation and maintenance costs;

• 
  

• Change the decentralized R&D support tool set purchase to a centralized purchase, and ensure that the tool safety is guaranteed, bringing economic and safety benefits.

• 
  

• Improve the efficiency of team collaboration, realize the transformation of the management model to the standardized pipeline management model, help improve the efficiency of team collaboration, and provide every software developer with a smooth cloud development management experience;

• 
  

• Strengthened the bank’s management and control of R&D assets, and provided technical support for the realization of R&D asset security management and control. At the same time, this is also an important support carrier for best practices and knowledge accumulation, in line with the development strategy of “science and technology leader”, and provides experience for informatization construction. Precipitation is of great significance.

• 
  

• The development and testing of the cloud management platform has realized the transformation of the current resource application model. Compared with the traditional operation and maintenance work model, the R&D environment has been transformed from a decentralized, independent construction, and independent management to a centralized, unified network and unified management model;

• 
  

• The transformation of asset management from the status quo of their respective management to a centralized asset warehouse model;

• 
  

• The R&D standard is a shift from the status quo of self-customization of technology and development standards to a unified definition model of development and testing standards;

• 
  

• The R&D process control has shifted from the status quo of offline visits and inspections to an online visual review mode.

• 
  

• Use an integrated cloud management platform to realize unified management of heterogeneous clouds, unified management of physical machines and virtual machines, and unified visual scheduling of resources;

• 
  

• The cloud management platform provides resource process self-service function, and resource application is convenient and fast;

• 
  

• Built-in a variety of commonly used middleware software automatic deployment and installation functions;

• 
  

• The automated operation platform provides operation and maintenance personnel with a unified portal for automated operation and maintenance, reasonably audits operation and maintenance commands, and prevents the execution of high-risk commands.

• 
  

• Use the container PaaS platform to adopt K8S cluster management technology to realize the unified management of the container platform;

• 
  

• The management platform integrates CI/CD pipeline functions to assist IT personnel in DevOps work;

• 
  

• Visual container lifecycle management, application release, and version iteration update;

• 
  

• Container and host service monitoring, capacity monitoring;

• 
  

• The container is automatically and elastically scalable, and the scaling strategy can be customized to meet the performance requirements of financial services for underlying resources.

• 
  

• Lack of resources to apply for a work order process, relying solely on manual transmission of resource application information, is inefficient, consumes a lot of operation and maintenance manpower at the level of resource processes, and cannot improve work efficiency;

• 
  

• The resource utilization lacks multi-dimensional report display, and it is impossible to judge the shortage and actual use of resources from a macro perspective;

• 
  

• The problem of resource maintenance and classification makes it impossible to distinguish the ownership of resources from a business perspective, and idle resources cannot be effectively recovered, resulting in inefficient use of some resources.
