Take advantage of the holiday, finally the "large Web site technology architecture Core Principles and Case Analysis" this book read. This book gave me a new understanding of the site architecture, the whole book is more simple and easy to understand, so that people who get started more easily understood. It introduces a lot of technical concepts. To reverse proxy and CDN and so on. I write two articles, is

This post is used to record some of the good information about the design learning on the Internet that will continue to be updated. http://www.tech-q.cn/forum-28-1.html Web idea-Architecture design http://www.cnblogs.com/sunli/Internet system Architecture related Blog Http://hi.baidu.com/injava/blog Internet, search engine, system architecture, Java E

easy to imagine, the biggest problem is how responsibilities are assigned. On the system architecture design of the biggest problem, in fact, is the allocation of responsibilities, allocation of reasonable, the implementation will be very flexible, the contrary will make the structure is very chaotic.The life cycle of software can be summarized into four basic processes, analysis, design, implementation, testing, of course, this is only the most sket

We know that the VPS server is a virtualization technology, build VPS server virtualization software and new cloud architecture solutions are many, they have advantages and disadvantages, therefore, different VPS Server service providers may use different virtualization technology to build VPS servers, Similarly, the construction cost of the VPS server will be different. The more common VPS virtualization technologies are: OpenVZ, Virtuozzo, VMware,

This series of blog posts will use the Microsoft Ria technical solution Silverlight and the scalability management framework managed extensibility framework (MEF), with the plug-in architecture design as the wire, I share my skills and experience in implementing plug-in system architecture design in the RIA system built based on Microsoft Silverlight technology. In view of my limited ability, if you have an

General design process of software architecture: first design the conceptual architecture, determine the most critical design elements and interaction mechanisms, and then design the actual architecture considering the application of specific technologies. What is a conceptual architecture? Features of the conceptual

C/S and B/S architecture comparison, s ArchitectureOverview In this rapidly expanding information society, we have to say that we are entering a brand new era, that is, the information age. A major and notable feature of the Information Age is the application of computer networks. Computer Networks have evolved from the initial centralized computing to the Client/Server stage (with two levels of C/S and three levels of C/S) to the most popular Browser

Distributed, microservices, cloud architectureJava language development, cross-platform, high-performance, high-availability, secure, service-based, modular, component-driven development modelFrom now on, I will record the process and the essence of the recently developed Springcloud micro-service cloud architecture, and help more friends who are interested in developing the Spring cloud framework, hoping to help more good scholars. Let's explore how

, such as secondary without the right to vote and priority set to 0. Of course you can add a arbiter (arbiter) in a replica set schema, arbiter cannot hold a copy of the data, and the arbiter plays a controlling role in the replica set architecture, when replica The primary is not available in set, and it is necessary to re-elect other members as new primary. A replica set can have up to 12 members, and only 7 members can be voted on at the same

After the conceptual design is complete, the architecture needs to be refined. We will build a development architecture for the development code section. This work is generally completed by an architect or Senior Programmer of a project team or company. The designer needs to comprehensively consider the business functions, non-business functions, and quality attribute requirements in the conceptual design.

and rarely changes , such as the product's category information, popular commodity information, and so on. In this way, when the application reads the data, it goes to the cache first, such as the cache is not or invalidated, and then fetched in the database, and re-written to the cache for the next visit. Therefore, it can improve the system performance, improve the data reading speed and reduce the storage access pressure .③ Distributed Cache Architectur
