Zero basic to IT, how to choose software testing and cloud computing operation and maintenance? Many people who do not understand do not know how to choose, so for this question, let's first learn about what software test engineers and what cloud computing operation and maintenance engineers?

Software testing: (the process of comparing the actual output with the expected output) describes a process used to facilitate the identification of the correctness, integrity, security, and quality of the software. In other words, software testing is a process of reviewing or comparing the actual output with the expected output. The classical definition of software testing is the process of operating a program under specified conditions to find program errors, measure software quality, and evaluate whether it meets the design requirements.

What does software testing do? Software testing is to use testing tools to test the function and performance of the product according to the test scheme and process, and even write different testing tools according to the needs, design and maintain the test system, analyze and evaluate the possible problems of the test scheme. After executing the test case, you need to track the failure to ensure that the product developed meets the requirements.

Software testing is a simple but in-depth task. Next, let's take a look at what we need to learn in software testing with the editor of Xi'an software testing training.

5 types of high-level development languages: C++, JAVA, Python, Android, HTML5

Three enterprise-level databases: Oracle, MS SQLServer, MySQL

6 mainstream testing tools: HP UFT, HP LoadRunner, HP ALM, Selenium, JMeter, Robotium

Full-stack testing technology: functional testing, performance testing, black-box testing, white-box testing, interface testing, full-stack testing technology: functional testing, performance testing, black-box testing, white-box testing, interface testing, Amax B testing, testing, interface testing, PC testing, mobile testing.

Cloud computing has been developed for ten years. Today, great changes have taken place in cloud computing, from the types of technologies and functional products to the industry and market. Many enthusiasts' understanding and demand for cloud computing have also developed from the superficial concept at that time to the stage of longing for in-depth exploration. Due to the different personal abilities of the broad masses of enthusiasts, the technical level of other individuals is also different. Here are some suggestions for beginners and cloud computing engineers:

If you are a person who has not done any work related to cloud computing, you need to learn cloud computing, you need to have knowledge of operating system, network, application services and so on. There are already many manufacturers on the market that implement cloud computing. Microsoft, IBM, Google, VMWARE and Huawei in the business camp all have very mature products. If you have enough money to buy any cloud product, you will get very professional technical support and services. (just kidding, you can't afford it.) if you are just an ordinary enthusiast, I suggest you start with technologies such as KVM,XEN,OPENSTACK,DOCKER in the open source camp. Because of their open source (free) features, they have been widely popular with major IT Internet companies and enthusiasts in recent years.

To learn the cloud computing technology of the open source camp, we should learn from the perspective of the management and use of the Linux system (about 20 days), as well as a small part of computer network communication technology (about 5 days), so as to lay the foundation for the virtual network technology in the cloud. Then I will also have some understanding of SHELL development and database system (about 10 days). At this time, there are conditions for a comprehensive study of the core cloud computing technology. For example, KVM,OPENSTACK,DOCKER containers, cloud technologies (20 days) master the architecture, functional roles and Iaas,Paas,Saas hierarchical classification, and master the deployment and operation and maintenance capabilities of private clouds.

If you are a person who has already participated in the relevant work, you have some knowledge of the above. The suggestion to you is that while you are proficient in the above contents, you also need to learn the language of Python in depth, and be able to monitor and manage common servers such as cloud computing services, container services, cluster services, caching and other common servers on the cloud platform, as well as secondary development work. Only in this way can we count as a more comprehensive cloud computing expert. Because you will no longer be faced with the independent servers, computer rooms, and equipment of the past. Instead, tens of thousands of computers, and cloud computing systems distributed in different cities or countries, carry out omni-directional, efficient and stable management. To sum up, transfer to IT, software testing and cloud computing operation and maintenance are all suitable for Xiaobai zero basic learning, which can be selected according to their own preferences.
