Turning yourself, people who are IT have almost unfamiliar, confused for the development of this industry, confused for personal careers, and confused with technology. A senior and I said that people who are not confused are not suitable for IT. In fact, I have always been confused for this, I have worked for a number of years, and I estimate that I will continue to worry. However, in this distressed, I seem to have seen some eyebrows, and at the same time added a number of fog. Here, I will share my experience and share it with you. The industry is first starting from the industry, IT is serving market demand, no market means no IT. From the market, I divided it into two blocks, household markets and commercial markets. Household markets include: desktop market, mobile market, etc. This market is held by companies headed by MS, and the rest is a large number of shared software. This market, I think Chinese companies are more difficult to enter. First operating system, office automation software enters the threshold too high, not technical, it is not formed. After all, the company like MS has a global market is not a company such as the land of Jinshan. In addition, domestic piracy is prevalent, in fact, it is just killed the largest domestic household software enterprises on the domestic market. The commercial market I will is mainly an enterprise IT market. In fact, this is a market that is known for most people, but this is a very huge market. This is also a more familiar industry. There are countless companies around the world in this industry: consulting companies, service companies, product companies, etc. Including famous IBM, Sun, HP, Oracle, BEA, CA, SAP, PeopleSoft, BCG, AC, Eisenzhe, etc. The biggest sales of IBM and HP, which are far more than 50 billion US dollars. The enterprise market can be divided into two parts: products and services. Products include software and hardware, seeing many products from all major companies, you can see a lot of products, hardware has servers, network equipment. Software is: Application Software (SAP, ORACLE, CRM, etc.), intermediate keys (Tuxedo, CICS, WebLogic, WebShpere, various MOM, etc.) and system software (operating system, system management, database, etc.). At present, this area is mainly held by foreign companies. The domestic enterprises may enter may not be large, the reason is also a question: market globalization. The development team of these companies is mainly abroad, so you want to go to this job, most of which need to go abroad. Service can be divided according to process: consult, implementation, maintenance, and training. This is a market that is relatively low, but it is also a very large market. This part of North America has gradually becomes more than surpassing the product market. Domestic IT companies are also doing this line (PC producers are not counted, in North America, this is almost made to manufacturing). The current form of this line is this: several consultations (Eisenzhe, IBM-Pu, Boston, etc.) have held the forefront, the highest-end consulting market. This is also a very rich market (a more experienced annual salary of more than 300,000). These companies mainly provide business and IT consultation. This part of the market is relatively high for domestic companies (requires professional skills), and domestic companies are not large because the market share is not big enough, and it is unlikely to raise such a high salary. Implementation is usually the development, customization, and deployment of us. Most of them use existing software to meet the users by customization according to customer needs. This part of the market is much larger than the consultation, and it is also a place where domestic and foreign manufacturers have gathered. Unlike product sales, service is sold. So people's ability to become an important factor. In this field, there are several types of roles: business analysts, architects, project managers, application designers, product engineers, programmers, testers.
