#39 - Section: Hybrid Cloud

Lu Haifeng explained, "The main thing is to protect the user's process. If one layer of the server fails, the five layers of servers can immediately continue running, seamlessly connecting.

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

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

Cui Sheng exclaimed, "President Lu, I've really had my eyes opened today. If you hadn't taken the initiative to visit, I wouldn't have known that our great nation has such high-end technology."

Lu Haifeng smiled faintly and said confidently, "Our great nation is full of talent, so it's not surprising that we have some cutting-edge technology."

Cui Sheng nodded in agreement, "The reason why we have been able to develop so quickly is because we have a demographic dividend."

Cui Sheng asked for advice, "President Lu, what do you think about our railway department also building such a large server farm?"

Lu Haifeng shook his head and said, "Director Cui, I don't think it's necessary to build such a large server farm at all."

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

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

"After all, you only need such a large server during the Spring Festival travel season. I estimate that you probably won't even need 100,000 servers at ordinary times, and the electricity, internet fees, maintenance, and operation of so many servers will require a considerable expense."

Cui Sheng thought for a while, nodded thoughtfully, and continued to ask, "President Lu, how much would it cost if we plan to use your technology?"

Lu Haifeng just wanted to test the real-world pressure of his cloud computing, so he had to explain helplessly, "Director Cui, I'm really not trying to sell you our technology."

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

"But to be honest, we also want to keep pace with the times, but we haven't had the technology to support it. President Lu, don't think too much, just treat it as if we're talking business, tell us about it."

A Deputy Director Liu who came with Cui Sheng said, "We want to develop the 12307 ticketing system into a system that combines the Ministry of Railways information database and also integrates telephone ticketing, online ticketing, window ticketing, and other related data, so that 12307 is no longer a simple online transaction system, but the largest bulk cargo transportation system in the country and even the world."

After a while, a technical staff member who accompanied them also said, "The technology of 12307 is indeed very difficult to solve. The current distributed database, caching, and load balancing technology can no longer meet the needs. You need to know that during the Spring Festival travel season, 12307 has nearly 30 billion visits per day. Such a large number of train ticket queries is an important reason that affects the performance of 12307, accounting for about 90% of the visits. What is even more棘手 is that: the queries during peak and trough periods are vastly different, and there is almost no way to strike a good balance between cost and concurrency."

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

The technical staff member said, "The current approach is to control the traffic from several key entrances to ensure system availability, but it will affect the user experience, and there are still phenomena of network delays, repeated payments, and inability to open the page, which has caused a lot of骂声."

As he spoke, the technical staff member shook his head with a wry smile.

Deputy Director Liu also said, "We have some technology, but the technology is not hard enough. It has been placed on your cloud server for a day, but there have been no problems so far."

Lu Haifeng thought for a while and then said, "Just now we also heard your technical staff say that about 90%. In the transaction-related process, multiple query requests will be submitted, not to mention the additional workload brought about by the emergence of a large number of ticket-grabbing software, all of which make the remaining ticket query system the focus of pressure for the entire system."

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

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

Cui Sheng said with interest, "Tell me more about it."

"Private cloud, as the name suggests, is your own cloud. We will 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 is operated by your technical staff. We provide training and technical support."

"Normally, you only need to use the private cloud, but if you encounter situations such as the National Day Spring Festival travel season."

"You can expand the traffic of the remaining ticket query to our public cloud with one click, which is the hybrid cloud."

"Using the two in combination can save costs and ensure safety."

"And the most important point is that we have an advanced cloud database, so you don't need to spend a lot of money to buy a database from Oracle," Lu Haifeng introduced.

Cui Sheng praised, "This plan is good. It can ensure data security and save costs. It's just how much does this public cloud cost?"

Lu Haifeng shook his head and said, "Because you are using it, the public cloud is free now. I only hope that the people can buy tickets to go home."

Cui Sheng said excitedly, "Good, good, good, then I thank you on behalf of the people. President Lu, I will go back to have a meeting now to discuss the online ticket booking matter. Please give me a plan as soon as possible. The budget will be 500 million first. If it's not enough, add more. Don't worry, the online ticket booking business belongs to you."

"Thank you for Director Cui's trust. We will definitely live up to expectations," Lu Haifeng thanked.

Cui Sheng said with a smile, "You're welcome. The main thing is that your technology is excellent. Please come up with a plan as soon as possible. No need to see me off."

"I must see you off."

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