A week's time is still strong, encounter the media and the public mouth of "life and Death"

For a whole week, the buzzing was still strong at the top 1 of the App Store's free list, and even though the flash of the flash was still in the pan, almost everyone was aware that the flowering of the night-blooming flower was an odd one.

Let's talk about some of the data, by the end of last week, the Dau app has more than 3 million, and growth is continuing, solar PV reached 200 million, the new user nearly 2 million, the cumulative total number of users have also exceeded tens of millions of dollars in the new round of financing starting also in the million-dollar level.

Happiness comes too quickly, there are always some unprepared, let this story appear more realistic.

Lu Shinto Problems of products

"Blockbuster Mode" is the crowning stroke--within a week, micro-bo camera, friends clap (everyone's image processing applications) have directly copied the past, Camera360 is the introduction of the KTV model of the subtitle effect-the founder of Willow himself also to the media slightly helpless to say, "Enough to remember in the social media after the hot, I saw the mito of the mobile President of the United States logged into the full memory, sent a picture like a play in Paris went away, then I thought, finished, they certainly want to do. American Mito is the best P-graph tool in the country, I think, they must also do this thing quickly, they may be sharper than me, sure enough, they quickly did similar functions. ”

But with the user and capital of the power to advance, the contradictions around this function more and more.

The contingency of the foot, this is a compromise and adhere to the parallel, its team consensus:

1, "Since everyone likes ' big mode ', the function depth optimization", so the full note in the iteration of the "large mode" of the entrance to the front, make it the default option, convenient for those who are admiring the user.

2, "' Large mode ' will eventually aesthetic fatigue, so the macro direction of the product, still need to serve those who left the user", therefore, based on the core value of the foot--in the words of Willow, is "location story + film framing" The realization of the needs of the literary scene-this is the strategic level of positioning.

However, this quick-witted trade-off, and not to the influx of VC satisfaction.

"The potential energy of growth, if not how to make the most of it, is the waste of luck and the risk of a return on investment," says one investor who has contacted the full team.

In short, VC hope that enough to take advantage of the homeopathy, the domestic-style crude filter function to the extreme, to the United States Mito This type of entertainment tools used as a reference, to enlarge the size of users, and then start the next round of financing. In fact, it's also a pragmatic option, and most VC responses to the team's desire to guide users to the film's framing to make Friends is "China is far from being the middle class that supports this need".

However, in this clash of values, VC does not occupy the advantage, because grabs is "net red" foot, VC at least in the ceremony needs to show sincerity and respect, but also beware of Peer's love.

At present, both sides are still careful to evaluate each other.

The problem of dealing with the big data explosion

Fame brings more than surprises to the mind, and it is another form of nightmare, they have no plans to meet such a level of users and traffic, like a crowded bus, the passengers are constantly crowded out of the car, the passengers are also difficult to obtain a comfortable experience-flashback, timeout, die, crash, no response, Loss of information-in addition to continually apologizing to users through application notifications, microblogs, and micro-letters, the full team is working on overcoming technical difficulties.

They can accept that users are tired of leaving, but the problem must not be in the hospitality way.

Most of the time, the full memory has to shut down or downgrade the app's part of the Non-core function, full rescue service side performance. Willow even in the micro-trust Circle of friends to invite the major cloud service providers to provide full access to the services Architecture development services, this makes it an extra "international column" in Shanghai's office: Engineers from a number of cloud-computing companies such as Jin Shanyun-who are mostly friends of Willow's friends or friends-gather together, Work together to help you solve server problems.

As a full choice of cloud service providers, Qingyun Qingcloud sent 4 senior engineers from Beijing, and after the diagnosis, Qingyun found that the main reason for the full capacity of the business structure of the level, the foot team only 3 engineers, of whom 2 were developed for iOS and Android applications, Many of the architecture code is a friend of willow part-time help write, who did not expect this will bury a huge hidden danger.

An engineer uses an analogy to describe a problem with a full memory: "Just like a park, the outside visitors and the space inside is not unbalanced, but because there is only one ticket entrance, so all the people are stuck in the entrance here, the outside lives and lives in not to come, inside and not fully use", so Qingyun in the private network deployment , load traffic to different servers.

"Cloud servers are agile and flexible, does not mean that it can automatically handle all the unexpected problems, because it is not expected to be in such a fast time to the influx of so much data, the full memory of the server set up on the hard disk space is not aware of the need to adjust capacity", in addition to the level of application server expansion, The engineer of Qingyun extends the scope of work function to the business end, such as database read and write separation, adjust cache structure, optimize SQL statement, introduce the relational database, adjust the code that affects CPU occupancy rate. After a day-and-night optimization, the back-end system has entered a stable period, the resource load tends to be balanced and the flow rate is stable at a rate of 30% per day.

"Small-run" is a lot of pioneering companies to promote the concept of technology, but if the lack of long-term vision, it is difficult to avoid this "downwind road drawback" situation. In a media interview, Mark Zuckerberg also revealed that he initially created Facebook with a TENS load to request the site architecture.

This unexpected catastrophe has also left the post of the CTO in the job--though some people are spitting it out, isn't it the right person to start a business?

What do they think of the full mind

Some of the comments from the industry are probably worth listening to.

Former Express Hotel Butler product manager Zhu Kun (Kentzhu) in the beginning of the start of the popularity of the evaluation said, "enough to remember this product, should be a big cup." The whole product is too heavy, the function of exploding fire is too easy to be grafted on other products which are more suitable for it.

Former NetEase photo album Product Director, travel notes the founder of the Guo Ziwei (Sterling silver) 's definition of foot is "a rapidly popular and rapidly disappearing product", in his view, travel agencies to gain market identity is relatively low, and to the development of entertainment tools, the full memory of the lack of team genes, so "life and death, It's hard at all. In addition, Guo Ziwei also mentioned the painting of the app, "one months sweeping the more than 10 countries in the App Store No.1, the spotlight is unparalleled." After one months, the volume gradually faded, 3-6 months later almost disappeared from the market. The tool's brand sedimentation and usage habits are decisive. ”

Thunderbolt's product director, Lan Jun (Blues), believes that a high degree of Gestalt psychology is a psychological school of thought that originated in Germany, emphasizing the totality of experience and behavior-"its laws imply that people in perception always organize experiential materials into meaningful entirety in a certain form, So it is the use of the user's experience in the film, the output of resonance works and dissemination. But Lan Jun also believes that "there is still much work to be done" if it is to develop relations and platforms.

The head of the Book of Thought, the CTO. Tsing Yi advised that it is not the travel enthusiasts that should be targeted but "want to use travel to show themselves to install Force group, can even try virtual travel", if fully positioned in the real travel agent, "then the future path will be relatively narrow, especially the road to the present will be particularly difficult."

The interface's social product director, Ma He, is more appreciative than sceptical that the industry's premature singing is just an empirical inertia, "the product makes a very expensive (forced) experience to do very cheap, and this in the Chinese market is a take-all skills."

Encounter the "Life and death" of the media and the public

About "phenomenon-grade products", most people's perception is actually asymmetrical, when the product is popular social network, give people feel as if everyone is in use, to the product is no longer have a strong sense of existence, but also let people feel as if no one.

"How to avoid becoming the next face" is a common headline in the media bombing of the foot, and face Meng is this is to laugh and cry, a reluctant to give the name of the team members said, whether it is face Meng or 2013 since most of the so-called "short-lived" mobile applications, in fact, live more than the industry imagined better, " After all, such a large user growth, even if the retention rate is lower, because the base is big enough, it is impossible to fall to the abyss of misery.

In the end, he said, the media may be keen to study cancer caused by obesity, but its conclusions may be worthless in refugee camps in Africa.
