Rebirth of the 80s New Farmer

Chapter 2183 Pillar Industries
Yang Zhengkun chose the second path. He was a little bit reconciled to the project that Baidu failed to achieve. If Baidu could continue to invest in it, it might not take long for that project to succeed.

But he also considered the risks.

Commercial companies are all profit-seeking, and this project is likely to face an embarrassing situation like that of Baidu, where too much investment produces too little output, and the result of no one using it is that the project will be withdrawn in the end.

But Yang Zhengkun did not change his mind, but resolutely formed a team to overcome this problem and build a distributed database.

The so-called database is to effectively manage and access a large number of data resources, improve the sharing of data, so that multiple users can access the data in the database at the same time; reduce the redundancy of data to improve the consistency and integrity of data, Provide data and application independence, thereby reducing application development and maintenance costs.

At that time, the databases in the hands of the Americans were all centralized databases.

The popular explanation of centralized database is to concentrate the storage and processing of data on one computer.

The advantage is that most functions such as modification, backup, query, control access, etc. are easy to implement.

The size of the database and the computer it resides on Don't need to worry about whether the database is in a central location, small businesses can set up a centralized database on a personal computer, while large enterprises can have the entire database controlled by a mainframe.

The disadvantage is that when the central site computer or database system fails, all users cannot use the system until the system is restored.And the communication overhead from the terminal to the central site is expensive.

Once there are many users extracting data at the same time in a period of time, it will also cause the server to crash.

Its biggest disadvantage is that the stored data is limited. Once this set of databases is full, you will buy another set of databases.

There is no win-win cooperation in the concept of Westerners, but only crazy plunder, and you will never stop until your last drop of blood is drained.

Westerners who have mastered monopoly technology will still invite wolf skins?
Take the reinforcement text of the world's largest database company as an example.

IOE——IBM minicomputer + Oracle database + EMC storage device, this is the hardened standard database device, and it has been the IT standard configuration of Huaguo enterprises from the beginning to the next 30 years.

The cost of this set of hardware equipment is hundreds of millions.

When a set of equipment is full, you have to buy another set of equipment. Companies like Alibaba and Baidu have hundreds of such equipment companies at their peak.

It also has the disadvantage that if you want to temporarily add some servers to carry more traffic, you have to place an order several months in advance.

There is also an overlord clause here, that is, once your company's data traffic drops, but the equipment is idle, you still have to pay an annual usage fee for it.

What's your opinion, sorry!Lift the toilet, love it or not!
In this way, the concept of distributed database was proposed, and it was proposed very early, and it was proposed in the 70s.

A distributed database does not store data on one computer, but on countless computers.

Each computer has local application and autonomous processing capabilities, and can also participate in the entire network processing at the same time, which greatly shares the pressure of computer work.

Twenty years later, people call this the cloud.

Distributed databases are incomparable to centralized databases in terms of processing speed and storage capacity, which greatly reduces costs.

But it naturally also has its shortcomings, and it is still a big problem that cannot be solved: these computers in series cannot reach the financial level of stability. If one of the machines goes on strike, it is easy to produce a chain reaction like a domino effect—— The entire network would collapse en masse.

Technically, it is not difficult to realize that if one machine fails, other machines can immediately make up the backup data. The difficulty lies in keeping the workload of each machine always balanced.If it is unbalanced, one of the computers with too much workload is prone to crash, which in turn leads to a big crash.

This is also the reason why distributed databases were proposed in the 70s, but they were old and unsuccessful.

This is what Yang Zhengkun did.

He worked at Ah Li from [-] until later, regardless of whether he succeeded, anyway, Ah Li’s Double Eleven server never crashed.

It was only when Wan Feng thought of Ah Li that he remembered who this person was.

Although his memory is a bit fuzzy, Wan Feng is sure that this guy is the one who made 'A Li Yun' for Ah Li.

Later, this cloud and that cloud of various websites were almost all created by Ah Li.

Thinking of this Wan Feng's heart beat wildly, is there someone guiding him somewhere?Just look for it and you will find the right one!
No matter how much money is spent, get this guy to Huaguang!Even if it breaks the salary structure of Nanwan Group, it's worth it.

This is a golden mountain!

This night someone was so excited that he didn't sleep until dawn.

The result was that his habit of getting up at 07:30 in the morning, which he had cultivated for many years, changed on this day, and he slept until [-]:[-] and did not wake up.

If it wasn't for Han Guang's family telling him how long he might sleep.

Wang Xuan did not break his promise, and called Yang Zhengkun to his office as soon as he arrived at Peking University the next day, and talked about recommending him to work on the database.

At first Yang Zhengkun was confused: "Someone in our country wants to build a database? Is it true or not?"

"Of course it's true. I'll arrange for you to meet and have a good chat with that person. Maybe there's something more surprising to you."

Yang Zhengkun nodded and agreed after thinking about it for a while, isn't it just for chatting!Not necessarily.

So, at noon on July [-]st, in Quanjude, Wan Feng and Yang Zhengkun met.

Yang Zhengkun has little hair and a thin body, he seems a bit shy.

He doesn't drink or smoke.

This is a bit difficult to handle, a bit cold.

But fortunately, Yang Zhengkun sent out the question in advance, and he was straight to the point.

"Ten thousand…"

"Professor Yang, you can call me Xiao Wan."

"Xiao Wan! I want to ask what does your company do?" Yang Zhengkun didn't stick to the address, if you call him Xiao Wan, you can call him Xiao Wan.

"Professor Yang! What our company does is a bit complicated. There are many projects ranging from mechanical processing to vehicle production to mobile phone and computer semiconductor material processing."

"So many? This is a group operation. I wonder which is the pillar industry of your group?"

Pillar industry?Wan Feng really hadn't considered this question.

What exactly is the pillar industry of Nanwan Group?At the beginning, it was undoubtedly motorcycles, but the development seems to be mixed up, and now it looks like it is a pillar industry.

But you can't tell Yang Zhengkun that they are all pillars. This is perfunctory.

"Cell phones and cars."

Wan Feng picked out two industries that are more representative of the group and spoke out.
