The financial data center target architecture consists of 5 parts. The five functions are mutually written to realize the technical standardization of cloud data centers, service-oriented capabilities, rapid supply, resource flexibility, and management automation.

Infrastructure: It consists of servers, storage, network/security, etc. In addition, it also includes the infrastructure of the computer room, including air conditioning and refrigeration, integrated wiring, etc. The infrastructure of different data centers is interconnected through the DCI network.

Resource pool: including the production resource pool, development and test resource pool, external network DMZ (Demilitarized Zone) resource pool, hosting resource pool, disaster recovery resource pool, etc., with the OpenStack cloud platform as the management center. Each resource pool consists of storage resource pools (centralized storage or distributed storage), computing resource pools (virtual machine resource pools, physical machine resource pools), and network resource pools.

Service domain: The service domain provides various services in a unified package, including computing services, storage services, network services, VDC services, disaster recovery services, big data services, disaster recovery services, and service platforms. Computing services include EIP (Elastic IP address),

• BM;
• storage services include elastic fast storage and distributed storage;
• network services include VPC, VFW, VLB, VROUTER; VDC services include service catalog management, automated operation and maintenance;
• disaster recovery services include BKaaS (Backup as a Service), cloud master and backup disaster recovery;
• big data services include batch processing services, offline analysis services, and in-memory computing services;
• disaster recovery services include application stores, grayscale publishing, and elastic scaling;
• service platforms provide services for Various platforms to ensure basic capabilities, including resource SLA, resource scheduling, metering and billing, service orchestration, VDC, and standard API.

Application domain: Various applications for specific business domains built on the basis of the standard API provided by the service domain, including direct banking, e-banking, Internet micro-loans, mobile payment, Internet wealth management, etc.

Management domain: Provide operation management,

• including user management,
• resource management,
• service catalog,
• resource scheduling
• scheduling,
• metering
