1. Summary
To write an abstract, it generally requires about 300 words. Write a certain subsystem in the platform, what specific work you are responsible for in the project, and what methods and approaches have been used to solve practical problems. To have good results, the writing content and questions need to be fascinating and arouse the teacher's interest in reading.
- Note: Do not write a system as a platform, for example, to implement it in a small system under a certain platform, so as to prevent false larges. Even with project experience, this is not easy to grasp. You need to look at the problem from the perspective of the platform and refrain from bluffing.
2. Text requirements
It is generally required to write 2000-2500 words within 120 minutes. This number of characters is not good enough, so I basically finished writing. It is important to start with the topic of the thesis. The domain of the topic must be clear, otherwise the writing will be biased. Here are a few error-prone problems:
- Narrowing or expanding the scope of the thesis may lead to partial topic: cloud-native architecture, do not divorce from the cloud (November 7, 2020 paper test question 3, service cloud is a trend, according to the actual project needs how to cloud, elastic scaling, service, and automation Wait to meet the meaning of the topic).
- The key terminology prevents errors: such as continuous integration/continuous deployment (CI/CD), make no mistake.
- Explain the key points and combine specific projects to avoid holes.
- Writing requires high-level construction, and the structure should not be described in too much detail, and specific issues can be discussed.
3. Summary
- At the end of the thesis, we must summarize the experience and lessons, solve the ideas and the direction of the problem, do not stop the thesis abruptly, to prevent the content of the whole article from being clear.
Due to the epidemic, the computer software test was cancelled in Beijing in 2020, so I chose to go to Shanghai for the test just during the CIIE. I also enjoyed the bustling night scene of the Magic City Shili Foreign Market in the evening. In the morning exam, the questions are generally not big; the first question of the case analysis in the afternoon is a must-do question, followed by 4 choices 2. Essay writing 4 choices 1 generally have their own best direction, so don’t worry, it’s time Quite nervous. The author wrote a summary, a little more than 300, and more than 2,200 in the body of the paper. I feel that the number of words is still lacking, so I must practice writing. The test on the computer keyboard still depends on handwriting. I feel that the synthesis and case analysis are still passable. There was no preparation and exercise in the thesis. I made some mistakes that shouldn’t be made during the rush. For example, the key terminology was wrong. CI/CD was written as AI/CD. The biggest problem is that there is no close connection to the topic. "The things behind the words are extremely different from the traditional ones, so let me mourn my thesis in advance.
4. Features of cloud services
Cloud servers have advantages that cannot be ignored in terms of performance, cost, flexibility, and work continuity. Renting cloud servers is not only a requirement for user development, but also a trend in the era of cloud computing technology.
Elastic scaling and dynamic expansion
Insufficient memory and disks can be dynamically expanded and purchased on demand to save costs.
Better overall performance
In terms of performance, cloud hosts can take advantage of elastic computing. Customers' businesses can be switched to the cloud freely and seamlessly, and they can have more powerful computing capabilities. At the same time, in order to maintain their own competitive advantages, cloud service providers will continue to use the latest technology and hardware equipment to upgrade, whether it is from a cost perspective, a technical perspective, or a security perspective, it is advantageous.
Customized solutions according to needs
Another advantage of cloud hosting is that solutions can be customized according to the characteristics of the enterprise itself. Various industries such as e-commerce, education, games, and media have different needs. The cloud solution based on cloud host rental is a solution that tailors CPU, memory, bandwidth, and high defense to meet the needs of users according to the business needs of enterprises.
Better business continuity
The speed of market changes is accelerating, so that the business is facing changes at any time. It is very difficult to transfer business data from a physical server in one place to a physical server in another place. The use of cloud servers will be very easy, fast, and safe, whether it is transfer between regions or global areas, which not only guarantees corporate business, but also achieves better continuity in changing conditions.
Lower usage cost
For enterprise webmasters, the purchase cost of traditional physical server rental is relatively high. The cloud host is a huge cloud resource pool established by cloud service providers. Enterprises only need to pay for the required resources, without having to bear equipment procurement and operation and maintenance costs. In addition, cloud hosting is more open than traditional servers. Especially under the trend of big data and artificial intelligence, the processing of massive data still needs to rely on cloud computing to complete.
Good performance configuration
Cloud servers have independent public network IP addresses, memory, CPU resources, independent execution programs, and system configuration. With independent host function, you can install the program by yourself and restart the host separately. Independent IP addresses such as HTTP, FTP, SSH, SendMail, Mysql, etc. are all independent, and only users can use them independently, unlike virtual hosts that are shared by many people.
Strong scalability
The cloud host can provide services other than WEB and FTP, and users can configure their own environment, install components, set up services, and install software. It is equivalent to a small server, generally has complete functions, and can install any software you need. The expansion function of cloud hosting rental is very strong, and it is fast and efficient.
Highly safe
Traditional website space is separated by system permissions and will be affected by other user websites. The isolation of cloud server software and hardware and the isolation of users from users can ensure its security. The cloud server is equipped with a hard firewall, which can effectively prevent hackers, ddos and network attacks.
Convenient operation
Cloud server rental can self-manage and use fault diagnosis tools: restart, reinstall, backup, repair, and real-time monitoring operation. Operation log and resource utilization statistics function can help administrators find and troubleshoot faults. Backup and restore, multiple backup functions enable users to restore data to a specified time state at any time. Easy migration, no need to stop the service during migration, which can meet the needs of almost all host services from low to high.
Cost-effective
Cloud computing servers effectively solve the problems of insufficient virtual host resources, excessive server resources and high prices. Moreover, the price of a general cloud host is low enough to be comparable to that of a virtual host, which is far lower than the price of a server. Using cloud servers, the configuration and performance are better, and the price is not expensive, which greatly improves the cost performance.
