metasys system extended architecture

I. Overview of Message Queuing Message Queue Middleware is an important component in distributed system, which mainly solves the problems of application coupling, asynchronous message and traffic cutting front. Achieve high performance, high availability, scalability and eventual consistency architecture. is an indispensable middleware for large-scale distributed systems. At present in the production enviro

I chatted with my colleagues yesterday and asked my colleagues a question. Since we already have such an excellent framework as spring and equinox, is it because we are working on the system, you can ignore the system architecture. This seems to be a very simple problem, but after studying the system, I think it is hel

Before discussing the nlayerapp project, let's first learn (or repeat) the hierarchical/multi-layer architecture and application system design principles. Many of my friends will think that these are old-fashioned content. As long as they are software practitioners, they will be very familiar with this content. But is that true? I will sort out this part here. On the one hand, it will lay the foundation for

the GPU. While it is often possible to hear Windows7 's big update on a DirectX 11.0 API, DirectX is also important for the graphics architecture of Windows systems, but that's not all. A graphics architecture includes how to use the GPU to speed up a wide variety of graphics applications (2D, 3D, print, etc.), display to the final display device, and include device detection and control. Windows 7 update

uses the Master/slave architecture. An HDFS cluster consists of a namenode and a certain number of datanodes. Namenode is a central server that manages the file system's namespace (namespace) and client access to files. The Datanode in a cluster is typically a node that is responsible for managing the storage on the node it resides on. HDFs exposes the namespace of the file system, allowing users to store

Portability Windows is designed to run on multiple hardware platforms. The original version of Windows NT supports the x86 and MIPS architectures. For the Alpha AXP platform of Dec (acquired by Compaq and then merged with HP), although it is a 64-bit processor, Windows NT runs in 32-Bit mode, Windows has also tried to support it. During Windows 2000 development, a native 64-bit version was not released. In the fourth-generation processor architecture,

(Handler) that conforms to the specific rule. Can you summarize what features are included in the end? Dataannotation: At first glance the data annotations seem to be of little relevance. It is actually used to correlate the event and handler, indirectly through the event trigger command, and this configuration is on the method, in attribute way support (similar to MEF).IoC: In fact, it is only a very primitive instantiation of the object, the

utilization multi-CPUThis architecture, which divides multiple processes, typically has two strategies: one that is broken down by function, such as a process that is responsible for network processing, a process that is responsible for database processing, and a process that calculates a business logic. Another strategy is that each process is the same function, and it only shares different computational tasks. Using the first strategy of the

Systems Overview (System Overview)Aerospike is a distributed, extensible NoSQL database built for three main goals: Create a resilient, extensible platform that meets today's web platform applications Provides the same robustness and reliability as traditional databases (for example, ACID) Provides operational efficiency (minimum manual participation) first published on Proceedings of VLDB (Very Large Databases)in, Aerospike

function partition in RPC rules and is an RPC framework for remote invocation between systems built in the Java language. Hessian:hessian is a lightweight remoting onhttp tool that provides RMI functionality in an easy-to-use way. Simpler and faster than Webservice,hessian. The binary RPC protocol is used because the binary protocol is used, so it is well suited for sending binary data. The core/minor structural elements of the RPC framework have been described in detail in one of my p

For traditional enterprises, it is necessary to innovate the mobile Internet application, and also consider the integration with the original system, and increase the requirement of the Cloud Platform network

information is designed to ensure that users can achieve unified user verification. This also shows that users cannot fully describe their basic information, especially in some professional fields. Such as information about family members of users in banking and insurance, and interests in social networking websites. This information needs to be extended by external applications. To provide a good user experience and good integration, the user

Reprinted Please note: http://blog.csdn.net/herm_lib/article/details/7252329 I have had several IM system development experiences, and one is still running online. Prepare to briefly introduce the architecture of IM systems for large-scale commercial applications. One of the most important aspects of designing this architecture is low coupling. The whole

Distributed File system also comes in handy.There is also a very common technology CDN acceleration at home and abroad. At present, the field of competition is fierce, it has been relatively cheap. Domestic and north-South Internet problem is more serious, using CDN can solve this problem effectively.The basic principle of CDN is not complicated, it can be understood as intelligent Dns+squid Reverse proxy cache, then need to have many machine room no

Of course, every step of the extension there will be a lot of technical implementation of the details, the subsequent time will write the article alone to analyze those details.After scaling up to meet basic performance requirements, we gradually focus on "usability" (that is, the SLA that we usually listen to when people brag,

the software reuse can be fully supported. A typical application of layered mode is layered communication protocols, such as the Iso/osi seven-tier network model. Hierarchical architecture also decomposes software systems by object and class, not by function. Design Requirements: The coupling between layers and layers should be as loose as possible, so that the specific implementation of a layer can easily be
