Chapter 112 Cluster + Load Balancing
Ding Sanshi and Liao Yong nodded approvingly.
This code deletion incident made the two of them feel a strong sense of crisis.
With the gradual expansion of the company's scale and the popularity and popularity of the company's various products on the Internet, there will definitely be jealous people, and those people will resort to some indiscriminate means to deal with them behind the scenes.
There are many people who are popular, not to mention a company, in the face of the huge interests, it is easier to make people feel bad.
"Mr. Ju, these days I will rent the two downstairs floors of the company as soon as possible. After that, I plan to arrange our company's technical team to work separately on the seventh floor and install access control to ensure a high degree of independence and safety for the technical team. Sex, so that most people with bad intentions can be put an end to it, what do you think?" Ding Sanshi opened his mouth slowly, and said a plan he thought about last night.
"Well, this is a good way, and the technical team itself is the core of our company, it should have an independent office space." Ju Hui nodded first, then shook his head and said: "But it's just like this, it's still worth it. It’s far from enough. This can only achieve the first layer of protection. Think about it, what if someone sneaks into our technical team? Isn’t there still a possibility of serious incidents like deleting codes? So, in the technical team There must also be a set of strict management norms, and every recruited technician must sign a confidentiality agreement, which is the first point."
"In addition, the code of the core product needs to be backed up and archived in multiple places. There are also codes and management rights on the official server, which can only be given to some core personnel and maintenance personnel. At present, we should mainly do a good job in these aspects. "
"Okay." Ding Sanshi nodded in agreement.
"Huizi, what is the disaster recovery plan you mentioned yesterday? I discussed this with Brother Ding yesterday, but there was no result." Liao Yong interjected and asked.
"Disaster recovery plan?" Hearing this, Ju Hui pursed his lips, thought for a while and then asked: "What do you think is the most important thing for us right now?"
"I think it should be the website." Liao Yong thought for a while and replied.
"Yes, I think it is also a website. If the code on our website server was deleted yesterday, then our website will definitely hang up. After that, all users on the Internet will definitely be unable to access our website. The consequences will be serious. .” Ding Sanshi agreed.
"You are right. The most important thing for us is the website. Based on this, the core of our disaster recovery plan is around our website, or our products. What we have to do is to find ways to ensure Their normal operation." Juhui nodded, and asked with a smile: "Do you have any ideas about ensuring their normal operation?"
After Ding Sanshi and Liao Yong exchanged glances, they smiled wryly and shook their heads at the same time. If there was any good way, they wouldn't ask.
"I have a plan, please listen to it first." Juhui had already expected the reaction of the two, so he was not surprised. He paused and continued: "Since our disaster recovery plan is For products like our website, can we get two servers or even three servers to deploy our website? If there are multiple servers, even if one of our servers dies, the other servers will also fail. Can guarantee the normal operation of our website!"
"Multiple servers?" Hearing this, Ding Sanshi and Liao Yong suddenly realized.
Makes sense!
Now only one server is deployed, and if this server hangs up, the website will hang up!
If two or three servers are deployed at the same time, the downtime of one of the servers will not affect the normal use of the entire website!
This mechanism can indeed improve the usability of website products to a great extent!
"However, how do we enable users to access which of our servers?" Liao Yong, who studied technology, suddenly thought of a core question and asked.
"Load balancing." Juhui glanced at Liao Yong appreciatively, and then said with a smile: "What I said before, you can understand it as cluster deployment, treat all our servers as one or more clusters, and control users' specific access to our server. Which server in the server cluster, we can use load balancing to achieve. In this way, not only can the availability of our website be greatly improved, but also the pressure on the server can be shared, and at the same time, it can increase the throughput of our website and improve the availability of the network .”
"Load balancing? Clustering?" Ding Sanshi and Liao Yong were taken aback when they heard these two novel words.
Juhui nodded calmly.
The deployment scheme of cluster distribution is very common on the Internet in the future. As long as the number of users of the product reaches a certain scale, it will basically deploy server clusters one by one. Some products with hundreds of millions of users, There are even hundreds of servers!Through distributed deployment, combined with load balancing, the high availability of products can be improved.
It's just that at this point in time in 1997, the number of netizens on the Internet is still very small, far from the level of exaggeration of later generations, so this concept has not yet reached the point where it is widely known.
But this does not affect Juhui to transmit this concept to Ding Sanshi and Liao Yong in advance, because Fuyi Company will use these technologies sooner or later.
"I'm just proposing this idea. You two can do some research on what I said first." Looking at Ding Sanshi and Liao Yong who were distracted, Ju Hui said lightly.
Although it is said that Juhui can achieve clustering and load balancing by himself now, that would go against his original intention of cultivating the abilities of Ding Sanshi and Liao Yong.Besides, the number of Internet users has not yet entered a period of rapid growth, and there is enough time for Ding Sanshi and Liao Yong to learn and grow. Instead of teaching them how to do it, it is definitely better to let them exercise their brains and thinking skills.
Therefore, Juhui only proposed his plan, and he was not going to intervene in the specific implementation work.But if they really can't figure it out, Juhui will consider coming out to give some pointers.
The concept of clustering and load balancing that Juhui said sounded highly feasible, which made Ding Sanshi and Liao Yong beside him frown and meditate, silently digesting the information in their hearts.
Looking at Ding Sanshi and Liao Yong who were lost in thought, Juhui pursed his lips with a smile, turned and left Ding Sanshi's office.
Ju Hui had just returned to his office when his cell phone rang.
He took out his phone and saw an unfamiliar calling number, Ju Hui pressed the answer button.
Ask for a recommendation ticket, thank you!
