balancing I. 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 needs of large distributed systems (websites), large traffic, high concurrency, and massive data. Therefore, you need to scale hor

Service-Oriented Architecture (SOA) is a component model that appliesProgramDifferent functional units (called services) are linked by well-defined interfaces and contracts between these services. Interfaces are defined in a neutral way. They should be independent of the hardware platform, operating system, andProgramming Language. This allows services built in various such systems to interact in a unified and universal manner. This neutral interfac

As the saying goes, standing on the shoulders of giants to see the world, general learning is also the first overview of the overall, and then one by one part of the break, and finally formed a train of thought to understand the specific details, Tomcat's structure is very complex, but Tomcat very modular, found the most core Tomcat module, The problem can be edged and understood, and the overall architecture of Tomcat is essential for further insight

This paper is compiled from Oracle documentation Warehouse Builder 11g Architecture and components Oracle Warehouse Builder is an information integration tool that can transform data into high-quality information using an Oracle database. The Oracle database is the central component of the Warehouse Builder architecture because it hosts the code generated by the Warehouse Builder repository and Warehouse

This article mainly introduces the architecture of the distributed monitoring system of the company. First, let's talk about what this system is used for. Our system is a GIS monitoring system that monitors vehicles in real time. It can be combined with maps to know where the car is located in real time, in-Vehicle basic information, because of the listening and photographing functions. Its structure is as follows: Because this system involves multi

ArticleDirectory Overview Relationship between Silverlight and. NET Framework A Brief Introduction to the Silverlight Platform In fact, I am hesitant to talk about the Silverlight architecture. Generally, many people are reluctant to look at these theoretical things. However, it is helpful to understand your understanding and be familiar with Silverlight. Although you may be confused when you are reading it, I think I should reve

I think many people have the desire to write their own frameworks, which can be used by various applications. However, for various reasons, I often imagine that I did not implement it step by step, and I am one of them. Whether you are a newbie or a newbie, you are welcome to visit. No matter whether it's a brick or a performance, why not leave traces to commemorate it? You need to plan your life, and the architecture is the same. If you don't have a

In software architecture design, layered structure is the most common and most important structure. Microsoft's recommended layered structure is generally divided into three layers, from the bottom to the following: Data access layer, business logic layer (or to become a domain layer), the presentation layer, as shown in the figure: Fig. 1:3 Layered Structure Data access layer: sometimes called the persistence layer, its function is mainly responsib

Common Parent Class Businessbase My friend's comments gave me a lot of motivation to write this series of articles, it seems that everyone is more concerned about this series. In order to follow the article to do a foreshadowing, I in the first half of this article to explain the overall structure of the blogengine.net, the latter part is mainly for the Businessbase class analysis. After downloading the s

Here we will talk about application servers in a three-tier architecture. For e-commerce websites, mature architectures are basically hierarchical. The layered structure is suitable for the human brain's way of thinking, and is very effective in solving scalability. Currently, major solution providers in the market have Corresponding Hierarchical solutions in e-commerce and general WEB application fields. There is almost no dispute over software

Background information NetEase Aesthetics in August 2016 on-line, is based on products and technology as the core, to a wealth of beauty products library, users use a collection of ideas for content carrier community-based products. Like most start-up Team technical architecture selection, in order to quickly go online, aesthetics in the beginning to choose a single application mode, all t

Datastore analysis In the fourth article in this series, I've given you an analysis of blogengine.net global configuration. In this article I will do a simple analysis of the more classical part of the blogengine.net Datastore, this datastore mainly completes the blogengine.net three major extension features (Extension,widget,theme) Data storage section, which provides a unified storage model for extended features. Datastore is based on the provider

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 l

Continue the previous discussion .... If ASP is used to process web application systems with complex business logic, the following disadvantages may occur: 1. Complicated ASP content: If complicated data processing is required, ASP will become much more complicated. 2. Security: Writing Data Reading and maintenance in ASP is not safe because hackers may find your aspProgramTo know your database, data table, fields, and even your business logic. 3. transaction processing is not easy: If y

It is also a heavy function point. Analyze the architecture before analyzing the source code to help understand the source code. In fact, before the advent of jquery, Dean Edwards's Cross-browser Addevent () design was already excellent, and the design idea of the jquery event system was based on that idea, so let's analyze the event bindings of Dean Edwards's predecessors first. A. jquery event prototype--dean Edwards cross-browser addevent () desi

Custom Theme Personalized theme is a perfect blog system in the necessary, but also a bright spot. In this article I will show you the third development feature of BlogEngine.NET, which is the custom theme. The emphasis of this paper is on the development specification and realization principle of blogengine.net. If you are familiar with the architecture of BlogEngine.NET, then developing a own theme is a very simple matter, if you do not know, then
