How To Perform Load Testing

In addition, the structure of cloud computing itself has spawned a large number of new services that can be used to assist in testing; For example, the resilience of the cloud improves load and performance testing, enabling developers to quickly and economically expand their software. In this article, the authors will introduce the interaction between cloud computing testing and software testing from two perspectives. By abstracting infrastructure, resource pools, and resilient usage models, cloud computing has a profound impact on the design and development of applications. It is natural to expect that this destructive power will have a significant impact on quality assurance. Testing is an integral part of software engineering design. ...

Now almost any application, such as a website, a web app and a mobile app, needs a picture display function, which is very important for the picture function from the bottom up. Must have a forward-looking planning picture server, picture upload and download speed is of crucial importance, of course, this is not to say that it is to engage in a very NB architecture, at least with some scalability and stability. Although all kinds of architecture design, I am here to talk about some of my personal ideas. For the picture server IO is undoubtedly the most serious resource consumption, for web applications need to picture service ...

A, virtualization virtualization refers to the ability to simulate multiple virtual machines on the same physical machine. Each virtual machine has a separate processor, memory, hard disk, and network interface logically. The use of virtualization technology can improve the utilization of hardware resources, so that multiple applications can run on the same physical machine with each other isolated operating environment. There are also different levels of virtualization, such as virtualization at the hardware level and virtualization at the software level. Hardware virtualization refers to the simulation of hardware to obtain a similar to the real computer environment, you can run a complete operating system. In the hardware virtual ...

The development of the Internet today is not the era of fish, but the time of fast fish eating slow fish. The winning principle of Internet products is a word-"fast". In various forms of product development, we always implement one of the values is "fast", how should we understand and interpret "fast"? What are the ways to implement this principle? First, rapid iteration, quick to do the Internet product is different from the traditional software development, we are faced with hundreds of millions of users such a huge user group, who they are, what preferences, what kind of habits, how to use our products, ...
