Cloud computing, this term has become more and more familiar to people in recent years. Many people feel that it is a very powerful technology when they hear the technical intuition related to cloud. After all, the word "cloud" gives people the first impression that it is far away. untouchable. But in fact, cloud computing is not so mysterious and untouchable. On the contrary, it is an IT technology that is easy to use. Whether you have a computer foundation or a beginner with zero foundation, you can get started through systematic learning.
So, what is cloud computing? To put it simply, cloud computing is to provide computer services to end users through the network. The services include data, network resources, storage functions and so on. The cloud services that ordinary people can access are mainly the acquisition of data information and the purchase and use of cloud storage. Cloud computing is all around us, and learning cloud computing is also a new trend.
Therefore, cloud computing is also a general term for various IT services. On the basis of traditional operation and maintenance services, more IT service content is added, such as cloud platforms, operating systems, databases, application development, and so on. The future world is destined to be dominated by cloud computing. In the ever-changing IT technology market, how to get started with cloud computing? Today, the small class will take you to understand together.
1. What is the prospect of cloud computing
Cloud computing has long been an important development direction in the technology industry. Many large enterprises and Internet companies have cloud computing-related businesses, and the growth rate is still very fast. According to statistics from the International Data Corporation (IDC), the global cloud computing market totaled US$86 billion in 2019 and is expected to grow to US$1.5 trillion by 2025. It can be said that the cloud computing market has a very broad prospect, bringing people many business opportunities and room for growth.
With the continuous expansion of the market, there is a demand for a large number of cloud technology talents. According to the statistics of the Ministry of Human Resources and Social Security, by 2025, there will be a talent gap of 1.5 million in domestic cloud computing-related technical positions; first-tier cities have the most demand for cloud technology talents, which means that the salary of cloud computing positions is very generous; and not only It is traditional Internet companies that need cloud technicians. Communications, transportation, education, medical care, industry and other fields are actively migrating to the cloud. Complete digital transformation requires the support of cloud technicians.
There is demand for employment, high salaries, and good development prospects. Cloud computing is not too popular as the first choice of IT technology in 2023!
2. The learning route of cloud computing
If you want to get started with cloud computing from scratch, it is best to learn from the following technical routes:
First of all, you must have a certain foundation , such as basic knowledge of computer network and operating system: Linux basic network settings, DBCP, samba, FTP, DNS, POSTfix, ca authentication, NFS, yum, pxe, shell programming... The stronger the foundation, Later in-depth study will be more handy;
Secondly, understand the basic theory and architecture of cloud computing ; you need to master enterprise-level website development technology, deployment and optimization; database technology; cloud platform, cloud native technology; automated operation and maintenance and network security and other technical content.
The technical points that need to be mastered include:
MySQL---ceph---mfs---redis---apache---nginx---tomcat---elk---kafka---kvm---zabbix---git---git lab+Jenkins---jumserver---ansible---docker---k8s
Then choose a cloud computing service provider , learn more about the specific products and services of the service provider, and learn related documents and tutorials, such as Alibaba Cloud, Huawei Cloud, etc. Certificates also need to be tested. It is best to take an intermediate level, which is also your skill and direct reflection of project experience;
Finally, based on the experience of using cloud computing, constantly improve one's ability from practice . Whether you have mastered the technology of cloud computing through self-study or training, entering the industry is not the end of learning, but the starting point; because only in actual work and exposure to different types of projects can you further learn about cloud computing The application of this technology has accumulated more experience in work projects and achieved technological breakthroughs.
3. What skills do you need to master to become a qualified cloud computing engineer?
As a qualified cloud computing engineer, one must first master the resource management and scheduling skills of the cloud computing platform, including cloud computing architecture, containerization technology, automated deployment and monitoring, high availability, etc. At the same time, it is also necessary to be familiar with the security protection mechanism and service optimization skills of the cloud computing platform, including network security, identity verification, data backup and recovery, etc.
It should be noted that with the rapid growth of cloud computing, there are also many problems, such as data security, multi-cloud complexity and solutions, network transmission delays, and so on. As a qualified cloud computing engineer, you need to have a certain sensitivity to the development trend of technology, and you need to learn and improve relevant capabilities in a timely manner.
4. Advantages of Cloud Computing
The biggest advantage of cloud computing lies in flexibility, scalability and low cost, because using cloud computing can quickly and efficiently expand network resources and services. Moreover, when responding to sudden demands, cloud computing can bring users a better experience by adjusting network resources in real time.
5. Disadvantages of cloud computing
With the rapid development of cloud computing, it will inevitably bring some problems. The first is the risk of security. Due to the openness and dynamics of cloud computing network services, they will be vulnerable to attacks. The second is complexity. There are many types of cloud computing service providers, and the service forms are diversified. Professionals are required to manage them, otherwise it is difficult to guarantee the stability and quality of services.
Cloud computing as a whole is still in a period of rapid development, and the technical content is also rapidly updated and iterated. The deficiencies will be gradually made up, and the advantages will be further expanded. So now is also a good time to learn cloud computing. If you meet the entry threshold, you will be able to enter the industry smoothly after about 5 or 6 months of intensive training and study.
In short, getting started with cloud computing requires systematic learning and technical practice. Through continuous trial and error and accumulation of experience, we can truly become an excellent cloud computing engineer. Moreover, the cloud computing market in the future still has huge room for growth and potential. I believe that as long as we work hard to learn and share, we will be able to create our own world in this era of Internet of Everything.
If you are still unclear about the introduction to cloud computing, learning routes or technical content, you can also take a private class~ I will reply as soon as I see it
