architecture series

1. Starting from the ibm pc xt architecture... In the initial PC design, CPU, ram, and I/O are connected by a bus, and all components must work in the synchronous mode, the CPU determines the frequency at which other devices operate. This will bring about a locked to each other effect, that is, everyone is limited to a universal clock frequency (clock frequency) that all devices can withstand, the overall performance of the system is not high. 2. Th

Ribbon is a new feature introduced from sharepoint2010. It makes the sharepoint2010 operation interface consistent with the office2010 style, enhances the user experience, and makes the sharepoint2010 display style more vivid and compact. Here, let's take a look at the knowledge about the architecture of SharePoint ribbon. First, let's look at the general structure of SharePoint ribbon. From the above structure, we can see that the tab is at the top

In this article, we will {Tagshow (Event)} "> The configuration is analyzed and discussed. The configuration part is far-fetched. However, I always think this configuration part is relatively independent and there are many references for blogengine. net design and implementation. In an enterprise-level application system, it is essential to configure some system global parameters. How do we handle these configurations? Generally, there are three steps as follows: 1. Some variable parameters are

1. Local multi-dimensional dataset The local multi-dimensional dataset and local mining model allow you to analyze the workstation when the client workstation is disconnected from the network. When interacting with a local cube, admod. NET and analysis management objects (AMO) will also load the local cube engine. Only one process can access the local cube file, because the local cube engine will exclusively lock the local cube file when establishing a connection to the local cube.A process can

Data Distribution in the Aerospike-Architecture SeriesData Distribution (Data Distribution) The Aerospike database isShared-NothingArchitecture: each node in an Aerospike cluster is the same. All nodes are equal and have no spof. Using the Aerospike smart partitioning algorithm, data is distributed across nodes in the cluster. We have tested our method in many cases in this field. This random number function ensures that the Partition Distribution err

Load Balancing principles System expansion can be divided into vertical (vertical) scaling and horizontal (horizontal) scaling. Vertical scaling improves the server processing capability from the perspective of a single machine by adding hardware processing capabilities, such as CPU processing capabilities, memory capacity, and disks, it cannot meet the ne

mechanism in time to replace with another cache machine, at that time we use 120Gof large memory, due to the size of the project business constraints, or when the machine memory is full when it is more embarrassing, so do large sites or use it carefully, after all, this is what we have doneA number of attempts to improve performance.2: Pattern of shardsThis model is still widely used in large-scale Web sites, it is characterized by a large amount of data can be distributed through a number of a

DNS is currently one of the most indispensable servers on the Internet, and every day we surf the web with the help of DNS. The DNS server can resolve the domain name for us, locate the e-mail server, and locate the domain controller in the domain ... In the face of such an important server role, we need to do some in-depth research, this article tries to explore the DNS architecture, so that people can better understand the principle of DNS.
