From the policy point of view, the state strongly supported the State Council to issue the Action Plan for Promoting Big Data Development in September 20 15, and systematically deployed the development of big data; 20 16 March, the 13th Five-Year Plan put forward "Implementing the National Big Data Strategy", taking big data as the basic strategic resource; In 2020, the state proposed to vigorously develop "new infrastructure", involving seven major areas, and big data center is one of them.
From this series of policy measures, we can see that the state attaches importance to big data technology. With more and more data-related applications and business models, it is more and more closely related to the lives of ordinary people. Mature data property rights and data security laws and regulations have been introduced at home and abroad to ensure the stable and orderly development of the big data industry.
From the perspective of industry development, with the development of information and communication technology, the amount of data collected, processed and accumulated by information systems in all walks of life is increasing, and the global big data reserves are exploding. In recent years, the growth rate of global big data reserves has maintained at 40% every year, and even reached 87.2 1% in 20 16 years.
According to the statistics of information network in recent years, the development trend of big data industry is explosive, a large number of enterprises are pouring in, and the scale of China's big data industry is growing steadily. From 20 16 to 20 19, the market size of China's big data industry has increased from 284.08 billion yuan to 538.62 billion yuan in just four years, and the growth rate has remained above 20% for four consecutive years.
At present, China is accelerating its March from a big data country to a powerful data country. With the continuous progress of new technologies such as the Internet of Things in China, by 2025, it will produce more data than the United States. The rapid generation of data and the implementation of various supporting policies have promoted the rapid development of China's big data industry. It is predicted that the growth rate of China's big data market will remain between 15%-25% in the future, and the scale of China's big data industry will reach a high level of1950.8 billion yuan by 2025.
Broad application scenarios Big data applications have penetrated into the Internet of Things, artificial intelligence, Internet, 5G, e-commerce, finance, games, transportation, media, medical care, real estate, government affairs and other industries. This also indicates that big data technology is indispensable to our daily life, manufacturing and economic development.
There is a big talent gap. Since 20 15, with the rapid development of the big data industry, the demand for big data talents is increasing. By 2020, the talent gap related to big data will reach 2.3 million. As big data is included in the "new infrastructure plan", this number will continue to grow.
According to friends' statistics, the average salary of big data engineers in 20021year was as high as 22.4K/ month, an increase of 10% compared with 2020. Among them, 1~3 years working experience salary is 20.4K, and 3~5 years working experience salary is 24.4K, which is obviously higher than other technical posts on the Internet.

A big data certificate worthy of examination
Alibaba Cloud ACP Big Data Certification is a professional technical certification for the architecture, development and operation personnel who use Alibaba Cloud Big Data products. ACP certification proves that you can formulate effective technical solutions and enterprise best practices based on Alibaba Cloud products. At present, ACP big data certification has two directions: big data engineers and big data analysts.
For job seekers, Ali enterprises or Ali eco-partner enterprises will recognize ACP certificates. If you want to join Ali, taking such a certificate will be your plus point.
For other non-Ali companies, such a certificate may be of little use, but taking this certificate at least proves that you have the corresponding big data professional knowledge and practical experience, which is a proof of ability, so it is also useful.
Huawei's big data authentication HCIE is specific to Huawei's HCIE- big data authentication, and its characteristics are mainly reflected in four aspects:
Deep theory and leading technology, focusing on data processing, data analysis, data mining, data visualization and so on. The course covers the cutting-edge technologies of big data analysis and mining, allowing students to keep up with the development trend of big data and systematically master the cutting-edge technologies of big data;
Originated from open source, superior to open source, based on open source community, including open source big data processing platform Hadoop, memory real-time computing Spark, big data platform data warehouse Hive, big data NoSQL database HBase and other components;
Experiment on the cloud and learn at will. In the experiment, Huawei Cloud is used as the experimental platform, and students can access and operate the experiment at any time, which reduces the learning cost and improves the efficiency.
Combined with cases and actual combat, based on the real project needs of enterprises, a large number of practical project application scenarios, such as bank time deposit business forecast, customer grouping and analysis of the permanent residence of floating population, are integrated into the experiment, which is convenient for students to apply what they have learned and integrate them.
Comparatively speaking, Huawei's big data authentication is much more difficult and expensive than Ali's, which is not suitable for novice Xiaobai and student party.
For the fresh graduates who want to enter a big factory, it is suggested to make a learning stage schedule, and at the same time, they need some certification certificates that are valuable and can be recognized by the market. It can not only connect your theoretical knowledge with practical application, but also help you find a job, which is a plus item for your job search.
