When the programmer opens the plug-in

Chapter 98 Traffic Bonus
After they tested the new back-end platform and felt that the effect was good, they started the grayscale launch.

Gray-scale online refers to using some machines to deploy new code, run it for a period of time to see, if the effect is good, add more machines, if there is a problem, you can go offline in time to see where there is still room for modification, and then Go online again.

After going online, they saw that the traffic peak has dropped a bit through the statistics of the online background, but it is not particularly obvious. After all, they are a grayscale test and only a part of the machines are online.

In the later test, I felt that this scheme was quite good, and there was no problem, so I cut it all over.

Looking at the traffic data in the background, I found that the current traffic is less than one-third of the previous one, which saves a lot of resources.

It shows that under the same network environment, twice as many users can be accommodated, and the outlet of a single server is also reduced, which is equivalent to saving half of the server network resources.

Because the server has a network card, the server can connect to the network only with the network card, but the network card has a size limit. Generally, the common one is Gigabit, and some are [-] Gigabit, but [-] Gigabit is more expensive than Gigabit.

In fact, their background is not just that simple. They also need to transcode the video, but the transcoding is performed by a special machine.

After all went online, they found user feedback. Before, there were always users who reported their video cards or audio cards, but now they found that the number of users who left messages saying cards was much less.

Some people even commented that they feel that it is very smooth now and there is no lag.

Among these users, there are also some remote places where the network is not so good. You must know that in the past, commercial CDN acceleration was required in these places.

In fact, this is also one of the reasons why Yao Shao and the others want to develop background technology.

They used a third party before, just like the last accident. When they encountered it, they could only find someone. Fortunately, the other party responded in a timely manner, but that almost made a list dirty. It's yellow, I believe they will not compensate this side.

If this set of technologies can be closed-loop, then you can completely digest these problems in your own internal team.

Now they have realized the technical closed loop, and with Cheng Wen's joining, not only has this goal been achieved, but it has also raised this goal to a new level.

Because they have completed a technological innovation and developed video and audio compression technology by themselves. In the words of the circle, this is a technical barrier.

Only you can do it, others can't, and it's hard to imitate. Even if you tell others what your technology has achieved, if you don't tell them the details, they won't know how to do it.

It's a Monday morning three days after they've fully switched over to the new technology.

Huo Feiyu is the technical director of a company, and they have a weekly meeting every week.

Because of some special reasons, they work from home. In fact, not only them, but also many companies choose to work from home like them.

Monday is the peak time for video and audio conferencing.

At the beginning, they used enterprise wx, but I don't know if there were too many people pouring in, so enterprise wx died at that time.

Later they found another dd, but they didn't expect dd to hang up too.

Huo Feiyu felt that it would be impossible to get better in this hour and a half, and it would take at least a few hours. They all thought about it and they would hold the meeting in the afternoon.

Huo Feiyu believes that such a large company should fix such problems very quickly, after all, this is a very serious problem.

If it is repaired 1 minute late, a large number of users may be handed over to competing products.

Just when Huo Feiyu was about to announce that the meeting would be held in the afternoon, someone said something in the group.

[I heard that Qingrou Technology's teleconferencing software is still available and has not crashed]

Huo Feiyu downloaded a soft meeting software, opened an audio conference, tried it with Xiao Li, and found it was quite smooth, so he asked everyone in the group to use this software to continue the meeting.

During the meeting, everyone felt that the software was very useful.

Their favorability for Qingrou Technology has been greatly improved.

Huo Feiyu feels that using this software has achieved their goal of sitting at home and living from the Internet.

Their meetings do not require everyone to turn on the camera. After all, at home, some people may still be in pajamas, lying in bed to work, and some may still be petting cats.

The same thing is happening in many other parts of the country.

Cheng Wen and his team also work at home, but they discovered this problem in a timely manner.

The most stressful thing is the few machines that model people. They are already fully loaded. Although the algorithms written by Cheng Wenfeng Le and the others are good, and they don’t need too much data to successfully model, they can’t stand the people who can’t use it. many.

Fortunately, they have another plan, that is, if the modeling is not completed, they will send the original data.

They immediately contacted the company's department that manages physical server resources and asked them to get some machines on top.

Let's overcome this business peak first, and then talk about the issue of capacity expansion.

They checked the load of the machine in the background and found that the load of the machine continued to rise at the beginning, then became relatively stable, and then began to decline slowly.

Looking at this curve, Cheng Wen understood that a considerable number of people had already built their models, so the pressure on the server was not so great.

Their server resources originally reserved some resources, just to deal with this traffic peak, but what they didn't expect was that the traffic was so large that they almost couldn't bear it.

Seeing that the load on the server was not so high, Yao Shao felt calmer, and immediately urged the person in charge of the machine to deploy some machines.

"Fortunately, the new code was launched two days ago, otherwise, they would not be able to bear this wave of traffic bonuses, and they would probably be choked." Yao Shao rejoiced in his heart.

Later, they checked the data and learned that the people who came this time were several times higher than the resources they had reserved. Without the audio compression algorithm, it would be impossible to survive.

Except that it takes some time to build the model at the beginning, the rest of the time, the amount of data sent by this teleconference is very small.

They are happy, but some people are not happy.

Some users leave messages on their website and leave comments under their app:

[You ducks don’t have to do so well, no one else can resist, why can you resist, what do other similar software think? 】

[Give you five points of praise, divided into five periods]
