The application of e-government in cloud platform architecture

1, Cloud base

Cloud, as an extension of it virtualization and automation, is being known to a growing number of people, the advantages of the cloud is very clear, the first to fully utilize the server computing resources, can allocate storage space, flexible scheduling and high reliability of the application of security and data security, can be obtained at any time, on-demand use, free expansion, get good scalability, system architecture flexibility greatly enhanced.

As a provincial e-government platform, across a number of urban areas, the overall system includes the provincial backbone platform and the corresponding operation group and management group, as well as the city level of the center, and the lower part of the county node composition, all parts play their important role, all the application platform, The system monitoring platform and control platform are all assembled in the provincial center platform to complete the relevant functions of e-government.

2, Cloud architecture

2.1 Cloud Advantage

Using cloud architecture concept in e-government IT system architecture, can bring us the following multiple technical advantages:

2.1.1 Storage dynamic extension

Using cloud storage technology to move State of the addition and expansion of disk space, from terabytes to PB order of magnitude easily dynamic expansion, at any time to meet the growing data requirements, so as to obtain a better capacity/price ratio.

2.1.2 Server virtualization

to virtual a server into multiple servers, the environment is completely isolated from each other, the integration of heterogeneous platforms and application integration, efficient use of resources, coupled with load balancing and highly available technology, To maximize the use of server resources and the protection of high reliability, significantly reduce the number of servers, to achieve low carbon emission reduction, to obtain a higher sex/price ratio, reduce TCO, and achieve higher Rio, so that the fish and bear the cake.

2.1.3 High Availability (high-available) and load balancing (load Balance) technologies in high reliability and load balancing

Cloud architectures to enable full and high availability of back-end databases and load balancing of front-end applications, A large burst of access can also be easy to deal with, balance server pressure and request hot spots, to achieve a perfect and efficient fast access experience.

2.1.4 Automation task

uses cloud architecture for unified management, erection of automatic installation server and Automatic Update upgrade server system, completion of automated operating system installation, automated update detection and upgrade services, automated data backup and monitoring work, Thus significantly reducing the labor intensity of IT departments, "one-click Installation" "One-click Upgrade" from the ideal into reality.

2.1.5 Centralized management and asset monitoring

Cloud ArchitectureCentralized management platform, can realize the physical server and Virtual server resources and performance monitoring, registration and management of assets, to achieve automated monitoring and report generation, the emergence of intelligent discrimination and active through mail, SMS, log alarm and other multiple ways to inform managers, centralized management, Making it possible for a person to manage hundreds of thousands of servers makes each employee a veritable generalist.
