Ideal for SaaS application Scalability: as the number of users increases, the system architecture does not need to be adjusted, but only needs to increase/enhance the corresponding hardware devices (application servers and database servers) you can. Generally, the application architecture is scalable. It generally refers to the implementation of "scale out", that

interaction between different objects. This interaction typically manifests itself as a series of messages between different objects.Component diagrams help visualize the high-level structure of a software system.A class diagram describes an object in an application system. This description does not refer to any particular implementation of the system itself.A hierarchy diagram is used to describe the logi

unacceptable.Expansion of CPU capacityCPU load dispersion is easier because the CPU's calculation does not have a dependency, that is, the result of the current request does not depend on the result of the last request. The stateless of the HTTP protocol is a good example. This CPU can not hold, I directly clone a few completely together, and the cloned service is generally referred to as the application server.The boundaries between the application

listens to me can quickly enter my role, ask a specific question, and understand my requirements.So how can you draw a high-quality architecture diagram?First you need to understand that the purpose of your drawing is to show whether it is business or technology, whether it is a whole or a part, whether it is completed or pending.After determining the purpose, it is necessary to determine what the key fact

1. When asked about the Linux architecture (which is how the Linux system is structured), we can refer to the answer: in large terms, the Linux architecture can be divided into two pieces:(1 User Space: User space is also included in the user's application, C Library(2 kernel space: Kernel space includes, system call, kernel, and platform architecture-related cod

application, get content and cache for the next visit. Squid servers can be either one or an array organized by a certain set of rules.PHP application can also be one or an array, the situation of a single server is relatively simple, array words need to consider the client session to answer the problem, the solution has two:1, Array server sharing session reply, such as unified use memcached storage session;2, the front-end server can determine which PHP server the client is processing, and al

Before the feeling a little bit confused, the structure of the design diagram first put up, compared to say.Models that the CAMCOCO architecture can support:1, b/s procedures, such as CRM and so on, and access to ordinary sites are no different, are from the Web server to operate;2, the app's server-side program. The app can be native, or it can be HTML5. The app has access to rest data through the Web serv

In the evening, the application of the architecture of the previous research to comb the next, organized an architectural plan, posted here to back upHere are a few key points for a personal understanding of the architecture:1.
