Rebirth Control Technology

Lu Haifeng explained: “The main purpose is to protect the processes used by users. If the first-tier server fails, the fifth-tier server can continue to run immediately and seamlessly.

"In the future, we will also build large-scale data centers in other provinces to ensure the security of user information."

Cui Sheng nodded, and then asked Lu Haifeng many questions like a primary school student.

Cui Sheng sighed: "Mr. Lu, my eyes have been opened today. If you hadn't taken the initiative to come to the door, I wouldn't have known that our big country has such high-end high technology."

Lu Haifeng smiled faintly and said confidently: "Our country is so big that there are so many talented people, so it's not surprising that we have some cutting-edge technology."

Cui Sheng nodded with great approval. The reason why we can develop so fast is because we have a demographic dividend period.

Cui Sheng asked for advice: "Mr. Lu, what do you think of our railway department also setting up such a large server group?"

Lu Haifeng shook his head and said: "Director Cui, I don't think there is any need to build such a large server group."

"Oh, what do you mean?" Cui Sheng asked.

Lu Haifeng knew that the other party had the money to build such a large server group, so he just smiled and said:

"After all, you will only need such a huge server during the Spring Festival. I estimate that it may be less than 100,000 in normal times, and so many servers will require a large amount of expenses for electricity, Internet, maintenance and operation.

"

Cui Sheng thought for a while, nodded thoughtfully, and continued to ask: "Mr. Lu, if we plan to use your technology, how much will we charge?"

Lu Haifeng just wanted to test his cloud computing on the road, so he had no choice but to explain: "Director Cui, I really am not selling our technology to you."

Cui Sheng waved his hand and said, "I understand, I understand Mr. Lu's good intentions."

"But to be honest, we also want to keep pace with the times internally, but we have never had the technology to support it. Mr. Lu, don't think too much, just treat us as if we are talking about business and tell us about it."

Deputy Director Liu who came with Cui Sheng said: "We want to develop the 12307 ticketing system, combined with the Ministry of Railways information database, and also need to combine telephone ticketing, online ticketing, window ticketing and other related data, so that 12307 will no longer be

A simple online trading system, but the largest bulk material shipping system in the country and even the world.

After a while, a technician accompanying him also said: "The technology of 12307 is indeed very difficult to solve. The current distributed database, cache, and load balancing technology can no longer be used. You must know that during the Spring Festival, 12307 will be close to the daily average

There are 30 billion visits. Such a large number of train ticket queries is an important reason for affecting the performance of 12307, accounting for about 90% of the visits. What is even more troublesome is that the peak and valley queries are very different, and there is almost no way to solve the problem.

Make a good balance between cost and concurrency”

After he finished speaking, Lu Haifeng said: "How did you solve it before?"

The technician said: "The current approach is to control traffic from several key entrances to ensure system availability, but it will affect the user experience. There are still network delays, repeated payments, and inability to open. This has been criticized a lot.

Voice."

As he spoke, the technician smiled bitterly and shook his head.

Deputy Director Liu also said: "We have some skills, but the technology is not strong enough. We have put it on your cloud server for a day, but there have been no problems yet."

Lu Haifeng thought for a while and said: "We just heard from your technical staff that about 90% of them will submit query requests many times during the transaction-related process, not to mention the emergence of a large number of ticket fraud software.

The additional workload has come, and all of this has made the remaining ticket query system a concentrated pressure point for the entire system."

"You can separate the remaining ticket inquiry module from the existing system of 12307 and have the ability to deploy it independently; deploy a remaining ticket inquiry system independently on the cloud, so that both 12307 and the cloud have a remaining ticket inquiry system."

"So I recommend that you use private cloud and hybrid cloud for the safety of users."

Cui Shengrao said with interest: "Please tell me in detail."

"Private cloud, as the name suggests, is your own cloud. We help you develop the software. If you need it, we can also provide you with the hardware."

"Put the server in your own computer room, and everything will be operated by your technicians. We will provide training and technical support."

"Normally, you only need to use a private cloud, but if you encounter a situation like the National Day and Spring Festival travel rush."

"You expand the traffic of remaining ticket inquiries to our public cloud with one click. This is a hybrid cloud."

"Using the two together can save costs and ensure safety."

"The most important point is that we have an advanced cloud database, so we no longer need to spend high fees to buy databases from Oracle," Lu Haifeng said.

Cui Sheng praised: "This solution is good. It can not only ensure data security, but also save costs. How to charge for this public cloud."

Lu Haifeng shook his head and said: "Because you are using it, there is no charge for the public cloud now. I just hope that ordinary people can buy tickets to go home."

Cui Sheng said excitedly: "Okay, okay, okay, then I would like to thank you on behalf of the people. Mr. Lu, I will go back to a meeting now to discuss the matter of online booking. You can come up with a plan for me as soon as possible. The budget will be first

At 500 million, it’s not enough to add more. Don’t worry, the online ticket booking business belongs to you.”

"Thank you, Director Cui, for your trust. We will definitely live up to expectations," Lu Haifeng said with thanks.

Cui Sheng smiled and said: "You're welcome, the main reason is that your technology is excellent, you can come up with a plan as soon as possible, there is no need to send it away."

"I have to give it to you"

Lu Haifeng sent Cui Sheng to the car and exchanged business cards before leaving.
