Overall solution design
Government affairs big data cloud platform overall architecture
Government affairs big data cloud platform overall architecture, as shown in the figure below:
Government affairs big data The overall architecture diagram of the data cloud platform
is divided into six major Part:
1, physical layer
The physical layer includes the cloud data center computer room operating environment required to run the government private cloud, as well as computing, storage, network, security and other equipment. The deployment of the cloud center computer room is designed according to partitions and is mainly divided into database area, business application area, storage area, system management area, network exit area and security buffer area.
2, resource abstraction and control layer
The resource abstraction and control layer uses virtualization technology to abstract underlying hardware resources, shield underlying hardware faults, and uniformly schedule computing, storage, network, and security resource pools. Its core is the virtualization kernel, which provides virtualization of host CPU, memory, and IO, and ensures cloud host migration, HA clustering, and dynamic resource scheduling through a shared file system. At the same time, network isolation of the multi-tenant virtualization layer is achieved through distributed switches. In the construction of storage resource pool, distributed storage technology is used to realize virtualization integration of service hard disks, and multi-copy (3-5 copies) technology is used to ensure high reliability of stored data.
3, cloud service layer
The cloud service layer provides three-tier cloud services: IaaS, PaaS and SaaS:
IaaS service: including cloud host, cloud storage (cloud data disk, object storage), cloud database service, cloud firewall, cloud load balancing and cloud Network (tenant subnet/IP/domain name, etc.). The IaaS layer service provides open API interface calls to the PaaS layer.
PaaS service: including message processing queue, general middleware (request agent, transaction processing, geographical information), data exchange platform, development and testing platform, providing standard and unified platform layer services for upper-level government applications, and providing API interfaces and SDK development kits , for SaaS layer software development and deployment calls.
SaaS service: including electronic supervision, administrative approval, collaborative office business applications, and government website groups that need to be launched in this period. The provision of this layer of services is completed by application software developers.
The above-mentioned cloud services provide self-service online full-process automated delivery to users commissioned by various departments and bureaus through self-service portals. Users can apply for services on the self-service portal. After approval, the corresponding cloud resources will be delivered to users for remote control.
4, cloud security protection
cloud security protection provides comprehensive security protection for the physical layer, resource abstraction and control layer, and cloud service layer, including anti-DDoS attacks, vulnerability scanning, host defense, website defense, tenant isolation, certification and auditing, Data security and other modules. Meet the deployment requirements of national security level 3.
5, operation monitoring and maintenance management
This module provides cloud platform operation and maintenance administrators with equipment management, configuration management, image management, backup management, log management, monitoring and reporting, etc., to meet the daily operation and maintenance needs of the cloud platform.
6, cloud server management
This module is mainly for government affairs big data cloud platform administrators to configure and manage the cloud services provided by the cloud platform to department and bureau commissioned users, including the release of service catalogs, definition of organizational structure, department and bureau commissions User management, cloud business process customization design, resource quota and billing policy definition, etc. The functions of this part are customized according to the provincial government affairs special operation requirements.
