Domestic cloud server public network bandwarest analysis

Cloud server public network bandwidth Ali Cloud, Tencent cloud and other cloud manufacturers are not cheap, why is domestic server public network bandwidth so expensive? Foreign server bandwidth is very cheap, and the server bandwidth network ( is detailed from the monopoly, shared exclusive, public IP address, etc.Domestic server bandwidth is so expensive:

Take Ali Yun and Tencent Cloud as an example. Public network bandwidth takes Beijing’s region as an example, generally 1M bandwidth price is 23 yuan / month, when the bandwidth reaches 6m and above, each M bandwidth rose to 80 yuan / month, how ? The price is very expensive. The server bandwidth network is moving, seeing foreign VPS, the upper 100 megabytes of bandwidth dozens of dollars, a few hundred yuan price, why is the price gap so much? As shown below:

Server bandwidth price

refer to:

The server bandwidth network will detail the reason for the domestic server, welcome to supplement:

Domestic server bandwidth mainly surround the three major operators, telecommunications, mobile and Unicom, like Ali Cloud, Tencent Yun is the bandwidth of renting operators, monopoly possessed leading, the price is that.

The server bandwidth network takes Ali Yun as an example, as long as the cloud server purchases the public network bandwidth, Alibaba Cloud system will assign an exclusive public network IP address to the cloud server. The public network IPv4 address is controlled by the United States, and the IP address of Ali Cloud is also an application for rents to ICANN. The server bandwidth network remembers that when the network engineer was taken, the teacher said that IPv4 address is facing depletion.

In Ali Cloud, Tencent Cloud Renting Cloud Servers, public network cables with broad domestic BGP high-speed network lines. When the cloud server provides services through the public network bandwidth, the cloud server must cover operators such as telecommunications, mobile, China Unicom, Tung Tong and Education Network. Regardless of which network access to cloud servers, the cloud server is to meet fast and efficient.

The server bandwidth network sees many VPS bands in foreign countries, the price is still very cheap, but this is VPS, non-server, many cases to limit traffic.

Like Ali Cloud, Tencent Cloud provides exclusive bandwidth, and sometimes users see 100g bandwidth, actually shared bandwidth, at all, unique effects at the network peak period. And some are shared bandwidth, even in us, it is not reached.

In fact, the public network bandwidth does not have to pursue how big, as an example of the web site, many times the big bandwidth is not used. For example, the server has a website with a website, the daily IP2000, the Alibaba Cloud 1M bandwidth server, the website is connected to the CDN, the 1M bandwidth is also enough, but many webmasters will vomit 1M bandwidth small water pipe, this server bandwidth network It is not a solution, it is not a big station, most small websites on the network, and there are hundreds of IP. Due to the waste of bandwidth resources, many times the user does not use so many bandwidth, so on the shared bandwidth problem on the 5th point, the banner of 100 megabytes is actually multi-tenant mode.

The above is a few more analysis of the server bandwidth network on why expensive domestic server bandwidth, for reference only, you also welcome you. Finally, Pushui Cloud, Domestic Cloud Server Selection Server Bring Wide Network Suggestion or the first choice of Alibaba Cloud, Tencent Cloud This major factory, whether it is cloud server performance, network bandwidth or reliability is guaranteed, Ali Cloud and Tencent Cloud The public network bandwidth is exclusive, and now the price is very cheap, everyone can pay attention to:

[Video] Capture Guangdong Intelligent Institute, academician of the Chinese Academy of Sciences reveals "brain science"

Wen, Figure, video / Yangcheng Evening News full media reporter He Ben

Intern Liu Ying

On November 28th, "Tongxin Guang and Macau and Dawang District" network theme activity media rises in Zhuhai, "Treasure Hunt", explore the Guangdong Intelligent Science and Technology Research Institute of Hengqin High-tech R & D Park (hereinafter referred to as "smart hospital" .

As an important scientific and technological guarantee for the important starting of artificial intelligent industrial ecotropic circles and Hengqin Guangdong, Hong Kong and Macao, the intelligent hospital exhibited an important role in the "Guangzhu Australian Technology Innovation Corridor".

The world’s first U m R 5T high field system magnetic resonance imaging system

Academician of the Chinese Academy of Sciences, Zhang Xu, Dean of the Guangdong Intelligent Science and Technology Research Institute, introduced that the primary task of the smart house is to carry out "brain science" research.

Human can do, learn, think, speech, etc., attributed to the magical and precise brain. In Zhang Xu, "Brain Science" is the crown in scientific research, combining the research results of "brain science" and artificial intelligence play an important role in social development, especially for emerging technology development. force.

Zhang Xu revealed that the current intelligent hospital has a number of technologies worldwide, and the future will make full use of Macao strategic status advantages, and focus on the high-level talent team and high-end technology innovation resources, and build the International Science and Technology Center of Guangdong, Hong Kong, Macau. Two corridor "strategic supported important science and technology platforms.

Sitting in more than 3,500 scientists engineers, three years have lost 24 billion, Shang Dynasty is not going to market?

Professor and doctoral gather, plus thousands of scientists and engineers, if such a dream lineup is used to build a company, will it be a pair of scenes?

As you say, you may not believe that such companies really exist.

Not long ago, Ai, a business Tang Technology, passed the HKCO listed hearing.

The unicorn in this AI is gathers more than 40 professors, more than 250 doctors. In addition, more than 5,000 employees, two-thirds are scientists and engineers.

What is even more cow has been founded in 2014, and Shang Tang has issued more than 600 papers in various journals, and there are more than 8,000 patents.

Describe with a sentence, that is, the scientific and technological content burst.

More unexpectedly, there is so many cow people, Shang Tang three years is still over 24 billion. . .

And today, the bad reviews are also preparing to smash the small hotspots listed on the market, and spend the story of the company, this company has the story of "AI Si Xiaolong’s head".

First of all, I said that I had to mention Tang Xiao ‘s big cow.

He graduated from the 1990s, he chose to go to the United States, and pursued a doctorate in Mirace, and he was in this period. He touched his face recognition algorithm.

After getting a doctoral degree, the big 佬 continued in research on computer visual algorithms at the Hong Kong University of Chinese University and Microsoft Asia.

He has also formed a multimedia laboratory of Hong Kong Chinese University, and Shang Dynasty Technology is also initially created here.

At that time, the field of face recognition has always been a bottleneck, which is how to improve the recognition accuracy of the algorithm.

Simply put, it is to improve the ability to judge that two photos are not the same. The accuracy of 97.53% of the human eye is considered to be a ceiling of the algorithm.

However, Tang Xiaou did not agree. In 2014, the Tang Xiao Team used the original GaussianFace algorithm to transcend his eyes, and the "monster" of 98.52% of the accuracy was created.

Subsequently, the high-yield Tang Xiao Team immediately released a more variatory DeepID algorithm, directly increased the experimental score to more than 99%.

The data of the anti-day is out, IDG’s investors also smell the wind and plan to invest tens of millions of dollars, helping the business of people’s face recognition technology, and Shang Tang Technology has also been formally established.

As for the company, I was named "Shangshuo", and their official explanation is that Shang Dynasty is currently the era of Chinese civilization, and the emergence of text has brought about human civilization. They think that technology is also the same. The founding emperor of Shang Dynasty was just calling soup.

Just, everyone is more likely to explain, that is, Tang Xiao will turn it from the professor to the business, and the professional soup, refer to business soup.

Shang Tang Technology has always been the fragrance of the capital market.

From 2015, the company has experienced 12 rounds of financing, with a total of $ 5.2 billion, and the business of Shang Dynasties is also greater.

In the computer visual field of its home, it is said that there is more than 400 million mobile phones in more than 400 million mobile phones in more than 400 million mobile phones.

The Chengdu Shuangliu Airport, Guangzhou Baiyun Airport, Zhengzhou’s subway station also uses brush face ban on Shang Sang Technology.

In other aspects, Shang Tang also established a universal artificial intelligence infrastructure based on his own old, and helping a AI for each field.

Take the smart city as an example, the merchant soup can use visual analysis, detect the displacement of the well cover, the fence guardrail, grab the image of illegal parking.

It is also possible to estimate traffic congestion, predict the occurrence of fires.

In this way, the technology of Shang Tang is used in life, and the corners of the city.

According to the last year’s data, Shang Dynasty also became China’s largest computer vision software company, Asia’s largest artificial intelligence software company.

And in comparison with clouds, according to the map, 视, etc., there are nearly 10 billion months of Shangjun, which has become the first of AI Si Xiaolong.

When I saw this, I would say that there is a friend who will say, since Shang Dynasty technology is so top, after the listing, I just can only rush to Rapuha, directly selling the business soup stock!

The bad review may be said to stop, be impulsive, because Shang Dynasty technology seems to be full of fruits, it is actually the money.

Shang Tang Technology can also be said to be a perfect representative of the AI ??industry, behind the light and bright, actually a huge loss. . .

Just say this, although the revenue of Shangshui Technology in the past three years is 1.85 billion, 30.3 billion and 3450 million. But after the various costs of research and development, in fact, Shangshui is a loss every year.

Among them, the light is more than 24 billion due to the three years.

Why do you burn this?

The bad review is simple to give an example, and the Shang Tang Guang is in order to build their own Ai superior centers, and the merchant soup has invested 5 billion.

But the superior center is in this place, but it can be eternal once after it is finished, because it is a truly anti-Gold beast.

The researchers of Shang Tang have been slightly estimated. Press the super-budget center that labeled Run (running) button, the iteration of the data training is at least 500,000 yuan.

So, selling hundreds of hot pots, it can be not enough.

So many scientists and engineers inside Shang Tang, every day, relying on "run" to train their own AI models.

And, this hasn’t counted the salary of scientists, and there are hundreds of millions of costs that have added the purchase of GPU clusters every year. Yes, AI is such a game of burning money.

This is not an example of Shang Dynasties. Other AI San Xiaolong’s investment in R & D is not small. It does not move to billions or even billion R & D.

However, it doesn’t necessarily have a result, and there is no need to commercialize. If you don’t invest money, it is afraid of being eliminated. The AI ??industry has fallen into such a strange circle.

Plus the construction cycle of the smart city project such as subway, airport, and the return period is also long; and many mobile phone manufacturers have implemented the AI ??algorithm, you don’t have money to make new stings, they will not pay again. you.

Loss, that is, it has become a homewinner in the AI ??industry.

These two years have attached importance to personal information, especially human face data, but also make simple face recognition data more difficult, so, "Shang Tang", who rely on this family, really encountered some bottlenecks. If this time is, the establishment is also a wave of direction adjustment.

The listed plan of this business soup is ready to raise 60% of the IPO, and then invested in Ai R & D.

So, as a research institution, these explosions and crazy money "Shang Tang" are really excellent.

But as a company, profitability and commercialization is their purpose. In this regard, "Shangjou" is still not a matter of time.

In addition, the story of the AI ??industry also reminds me of an innovative field a theory called "Valley of Death".

Simply put, technology innovation has been proposed, and there is still a long way to go between the technology innovation. Most of these projects will die on this road, and this divide from scientific research to industrialization is also called "Valley of Death".

In the past few years, the AI ??frenzies, after the PPT, the era of increasing, today’s AI industry seems to be in this deep valley.

Although AI has been applied in many fields, 97% to 99% accuracy of the leap, may take hundreds of millions of real gold and silver investment, but to tell the truth to the people of bad reviews, I feel true. not very big.

And from now on the performance of the AI ??industry, losses are likely to become a homemade.

Finally, the profitability of these AI industries may have doubts, but for the future of AI, the bad review is still very optimistic.

Just like a lot of money, in the 1950s, the "modern communication theory", UNIX operating system, mobile phone technology Bell laboratory, did not expect that these technologies can be decades later Root root germination, even change the world.

The AI ??industry may also be the same, I believe that all the way to burn money all the way to the current "Shangjun", will also plant a seeds, and they are also likely to change the fruits of the world.

Bitcoin inches closer to becoming legal tender globally

SAN SALVADOR: El Salvador on Tuesday becomes the first country in the world to accept bitcoin as legal tender, despite widespread domestic skepticism and international warnings of risks for consumers.

President Nayib Bukele’s government claims the move will give many Salvadorans access to bank services for the first time and save some $400 million in fees on remittances sent home from abroad every year.

“Tomorrow, for the first time in history, all the eyes of the world will be on El Salvador. #Bitcoin did this,” Bukele said on Twitter Monday.

He started the ball rolling Monday evening by announcing El Salvador had bought its first 400 bitcoins, in two tranches of 200, and promised more were coming.

The 400 bitcoins were trading at around $21 million, according to the cryptocurrency exchange app Gemini.

Recent opinion polls showed a majority of El Salvador’s 6.5 million people reject the idea and will continue using the US dollar, the country’s legal currency for the last 20 years.

“This bitcoin is a currency that does not exist, a currency that will not benefit the poor but the rich,” said skeptic Jose Santos Melara, who took part in a protest by several hundred people in the capital San Salvador last week.

“How will a poor person invest (in bitcoin) if they barely have enough to eat?”

In June, El Salvador’s parliament approved a law to allow the crypto money to be accepted as tender for all goods and services in the small Central American nation, along with the US dollar.

The bill, an initiative of Bukele, was approved within 24 hours of being presented to Congress — where the president’s allies have held a majority since March.

Experts and regulators have highlighted concerns about the cryptocurrency’s notorious volatility and the lack of any protections for its users.

– Skepticism –

The government is installing more than 200 bitcoin teller machines, some guarded by soldiers to prevent possible arson by opponents.

And Bukele has promised $30 for each citizen who adopts the currency.

“These are decisions the administration and lawmakers have taken without consulting” the population, said Laura Andrade, director of the Public Opinion Institute of the Central American University, which found in a poll that 70 percent of Salvadorans opposed the move.

“We see that people do not perceive a positive impact to significantly transform their living conditions,” she told AFP.

Nearly two-thirds of Salvadorans questioned for the poll said they had no interest in downloading the “Chivo” electronic wallet that will allow users to buy and spend bitcoin.

Oscar Cabrera, an economist at the University of El Salvador, said the currency’s high volatility will have a “negative impact” on consumers, affecting the price of goods and services.

The currency fell beneath $30,000 in June, less than half its all-time high of more than $64,000 just two months earlier.

For its part, the Salvadoran Foundation for Economic and Social Development (FUSADE) said it was “unconstitutional” to make it compulsory for merchants to accept bitcoin as a form of payment.

– ‘Malign actors’ –

Bukele, who is popular but under fire in several quarters for moves to tighten his grip on power, has accused opponents of seeking to “sow fear” among Salvadorans, few of whom have access to formal banking services.

Remittances account for more than a fifth of GDP in the dollarized economy, mainly sent in dollars via agencies such as Western Union by an estimated 1.5 million expats.

According to World Bank data, El Salvador received more than $5.9 billion in 2020 from nationals living abroad, mainly in the United States.

And the country is relying on this money to boost a struggling economy that contracted 7.9 percent in 2020 due in large part to the coronavirus pandemic.

Economists and international bodies such as the World Bank, International Monetary Fund and Inter-American Development Bank have expressed concerns about El Salvador’s bitcoin adoption.

The United States has urged El Salvador to ensure a “regulated,” “transparent” and “responsible” use of bitcoin, and to protect itself from “malign actors” such as hackers seeking ransom money.

Bitcoin is criticized by regulators for its potential for illegal use — notably in laundering money from criminal activities and financing terrorism.

But not everyone is against it, and according to Bukele in late June, some 50,000 Salvadorans were using bitcoin.

Many of them are in the coastal town of El Zonte, where hundreds of businesses and individuals use the currency for everything from paying utilities bills to buying a can of soda.

Started as a project by an anonymous bitcoin donor, the town until recently boasted El Salvador’s only bitcoin teller machine.
