Client Server System Architecture

Now almost any application, such as a website, a web app and a mobile app, needs a picture display function, which is very important for the picture function from the bottom up. Must have a forward-looking planning picture server, picture upload and download speed is of crucial importance, of course, this is not to say that it is to engage in a very NB architecture, at least with some scalability and stability. Although all kinds of architecture design, I am here to talk about some of my personal ideas. For the picture server IO is undoubtedly the most serious resource consumption, for web applications need to picture service ...

1, cloud base cloud, as an extension of it virtualization and automation, is well-known for more and more people, the advantages of the cloud is very obvious, first of all, can make full use of server computing resources, to 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 to achieve 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 branch center ...

The storage system is the core infrastructure of the IT environment in the data center, and it is the final carrier of data access. Storage in cloud computing, virtualization, large data and other related technologies have undergone a huge change, block storage, file storage, object storage support for a variety of data types of reading; Centralized storage is no longer the mainstream storage architecture of data center, storage access of massive data, need extensibility, 　　Highly scalable distributed storage architecture. In the new IT development process, data center construction has entered the era of cloud computing, enterprise IT storage environment can not be simple ...

Game Architecture Analysis-game Cloud series five talk about architecture, divided into two, one is the software level of the Code architecture, and the other is the hardware level of the system architecture. Software level, module division, Code reconfiguration and business layer architecture. System level, to network, deployment, server cluster-oriented. The architecture of software hierarchy lies in the development of early code. Hardware-level system architecture, in the late deployment of the server online.   Today's content is primarily biased towards the system architecture in the gaming domain. Talk about system architecture, no outside of those technologies, what load balance ah, what database ...

Speaking of architecture, divided into two pieces, one is the software level of the Code architecture, and the other is a hardware-level system architecture. Software level, module division, Code reconfiguration and business layer architecture. System level, to network, deployment, server cluster-oriented. The architecture of software hierarchy lies in the development of early code. Hardware-level system architecture, in the late deployment of the server online.   Today's content is primarily biased towards the system architecture in the gaming domain. Talk about system architecture, no outside of those technologies, what load balance ah, what database vertical, horizontal partition Ah, front-end/back-end cache ...

ERP product in the end, b/S or C/s structure? In the ERP industry, the war of words on C/s and b/s began in 2000, has not ceased. 　　Until today, the survey data of related products and their use in the enterprise seem to have given the answer. Obviously, b/S and C/s have different advantages and characteristics, they can not replace each other. For example, for the browse-oriented, input simple applications, b/S technology has a great advantage, now the global overwhelming web site is evidence, but for interactive complex ERP and other enterprise applications, B ...

Original: http://hadoop.apache.org/core/docs/current/hdfs_design.html Introduction Hadoop Distributed File System (HDFS) is designed to be suitable for running in general hardware (commodity hardware) on the Distributed File system. It has a lot in common with existing Distributed file systems. At the same time, it is obvious that it differs from other distributed file systems. HDFs is a highly fault tolerant system suitable for deployment in cheap ...

Introduction Cloud application developers and DevOps have successfully developed tens of thousands of applications for IaaS (Amazon AWS, Rackspace, etc.) and PAAs (Azure, Google App Engine, Cloud Foundry, etc.) platforms. These platforms provide basic security mechanisms such as authentication, Dos attack defense, firewall policy Management, logging, basic user and account management, but security concerns remain the primary obstacle to enterprise cloud implementations. Security concerns for the cloud, deploying from a secure configuration ...

Using the latest 4, 8-way IA server architecture of High-performance server cluster system, the use of the leading VI (Visual Interface) technology, effectively eliminates the communication bottleneck between nodes in the system, and the system uses load balancing technology so that user equipment can be fully utilized,    and achieves 4 9 reliability, has the extremely high product price-performance ratio, provides a strong database server platform for the Internet application. ...

1 Introduction with the progress of science and technology, the environment complexity of IT industry is increasing day by day, more http://www.aliyun.com/zixun/aggregation/13546.html "> It budgets are used to maintain the infrastructure and maintain the normal operation of the application, rather than to better meet customer needs. The emergence of the cloud seems to bring new hope to people, so some people make such a prediction-the future cloud era. 2 Cloud Architecture System Design 2.1 cloud architecture concept and special ...
