Introduced:There are a lot of explanations on JPDA (Java Platform Debugger Architecture) online, for example. I do not repeat the invention of the wheel, this set of articles mainly from the practice of code Analysis, carefully analyze the characteristics of the platform, and some of the problems clarified and misunderstanding.Practice:If we look at JPDA from the functionality of Java Remote Debug and use the socket's communication, the whole process

Today, my colleague asked me what is the use of web service in the system? What is the difference between it and the general direct writing on the client? What are the advantages?
It is really interesting to answer this question. Since I have asked this question, it means that there are some preconditions for not reaching an agreement. It is easy to explain the technology itself.
Therefore, we should first clarify the background of recommending the use of the SOA
High concurrency Server Architecture Evolution of large website architecture
Three server requirements:
High Performance: rapid response to a large number of requests
High Availability: uninterrupted, automatic failover occurs, which is called fail over (Failover)
Scalability: Cross-machine communication (TCP)
In addition, any network system structure can be abstracted into a C/S
Recently, the company requested that the architecture of a product be changed from two layers to three layers (the reason is: For security review, a three-layer architecture is required because the database port is only open to the server ), when I heard it, I fainted.
The initial architecture of the product was three layers. Later, due to various requirements du

In the technical documentation, we often find that topology, architecture, and struct are not strictly differentiated. Sometimes we can see that a topology becomes a pure echure, and sometimes a struct becomes a pure echure.From a rigorous point of view, how should we define and distinguish them for correct use? My personal understanding is as follows: 1. the focus of topology is network deployment, such as the distribution of data centers. architechu
Advantages and disadvantages of C/s architecture:Advantages1. Because the client is designed independently, it can realize the personalization2. Because the client needs to be installed, it can not need to be installed and loaded repeatedly3. Because the client is independently developed, it has the ability to design the client securely4. If you encounter different operating systems, you need to develop a set of clients for different operating systemsDisadvantages1. Because the client is not req
