Google scolds Microsoft for Facebook Open source data Center Kingdom

Unlike Google, which is strictly confidential, Facebook has not only been completely dismissive of Google's new design of servers and data centers and its open-source design. Every Google employee needs to sign a confidentiality agreement that is not needed on Facebook. Even Microsoft, which has always been conservative, has been unable to breathe, releasing some of the details of the Dublin data Center. However, Google's data centers are strong, according to former Google employees. But open Facebook has gained more adherents, including Intel, Dell, Asus and Rackspace, all joined in Open Compute project. Wired reporter Cade Metz in-depth Facebook at Prineville's data center and interviewed general manager Ken Patchett.

Facebook's newly designed server is freedom, a server that can adapt to the needs of a large social network, and traditional servers are unsuitable. Rather than HP and Dell branded servers, Facebook has created "Vanity-free" servers, even with beeps, which make data centers more efficient to run.

Open source servers account for almost half of the data center. They are used as Web servers and memory caches (data is stored in memory, faster to read and write than stored on a hard disk), while traditional servers are also responsible for database operations. "At the initial stage, we want to launch a new server," Patchett said, "and we're going to continue to improve it and expand its capabilities." ”

Open source servers are slightly taller than traditional rack servers and can accommodate larger fans and heat pipes. Although the fan speed is slower than the traditional server, but still can emit the same amount of air, so Facebook can reduce the heat energy. At the same time, the larger heat conduction tube does not need the cold air to dissipate heat.

Google is no big deal.

Google's data centers are also using designs that do not have water-cooled cooling, and they have built their own servers, but Google does not want to talk about it. Although Google published information about data centers and servers in 2004, that's all we know. Wird reporter contacted Google on this topic to interview, but did not receive valuable feedback.

Google's data centers surpass any competitor, according to Dhanji Prasanna, a former Google engineer. But he did not want to disclose more information. All Google employees, including Ken Patchett, have signed confidentiality agreements.

Facebook's great contempt for Google is that it designs open source in its Prineville data center and becomes part of Open Compute project. "It's time to open up the design of the data center, just like the movie" Fighting Club "advocates Fight," said Jonathan Heiliger, vice president of Facebook technology. " Facebook will also help companies that want to join in data center design for a long time.

"We firmly believe that this will give us greater value in the long run," Heiliger said, "Like Open-source software, many people are looking at our design." This is just version 1.0 and we want it to help everyone. ”

Desert as the Open code

Facebook has designed its own Prineville data center, and it also believes its own model applies to the industry as a whole, or even more advanced. In the fall of 2011, Facebook launched a nonprofit open Compute Project and gained support from many industry giants such as Intel, Asus, Rackspace, NTT and Netflix.

Facebook has rejected Dell's solution in building its own data center. But the IT giant says Facebook's design can meet the requirements of many small data centers.

In a way, Dell is defending its reputation. On another level, this may be a gimmick. But many data center designers do consider building a data center on Facebook's design.

Wired: Uncover the story behind Microsoft Bing and Google search

In 2010, there was a major change in the Google search engine. Google has migrated its search to the new software platform, which they call "caffeine." Caffeine is Google's own design, caffeine allows Google to quickly add new links (including news reports and blog posts) to its own large-scale web site indexing system, compared to previous systems, the new system can provide "50% new" search results.

And it's all thanks to Google's groundbreaking mapreduce. Google search engine algorithm is only part of its search engine, in the background to support the Google algorithm infrastructure is the real behind-the-scenes hero, its infrastructure can quickly index links to thousands of ordinary servers. The success of MapReduce also directly drives the development of Hadoop. Today they are affected by Facebook, Twitter, ebay, LinkedIn and ebay, and they have to move forward to accommodate the tide of the big data age.

Google has won praise in the field of web-based distributed computing systems. And Harry Shum, head of Microsoft's Bing search engine, thinks Microsoft has no "caffeine" support, but Bing search (which uses tens of thousands of server software platforms to process data) is not lost to Google. The advantage of Google caffeine is fast crawling, indexing, and server documentation. And Bing is very good at it. But all this requires infrastructure support.

Google and Microsoft will continue to play in the search arena, both of which are aware of the importance of fast updating indexes. Both Google and Microsoft are thinking of a new direction (distributed database). The devices that store data in a global server will become a future trend, but this requires more efficient organization. But this is not the end, the evolution of search engine technology will continue.

Yahoo Lab Cloud Chief scientist Ramakrishnan job-hopping Microsoft

Yahoo's lab search and cloud computing field chief scientist Raghu Ramakrishnan

It is reported, Yahoo Laboratory search and cloud computing domain chief scientist Raghu Ramakrishnan has resigned from Yahoo, job-hopping to Microsoft. Raghu Ramakrishnan also played a key role in Yahoo's personalized technology development.

Raghu Ramakrishnan will serve on the Microsoft SQL team, sources said. Raghu Ramakrishnan has been at Yahoo since 2006.

Raghu Ramakrishnan is one of several key researchers who lost before Yahoo's upcoming research and Development division. It is not surprising that Yahoo's senior researchers are losing their jobs.

"Three categories" of cloud computing in the U.S.

Wanted analytics analysis shows that the rapid development of cloud computing industry and the relatively small supply of talent market between the formation of a huge employment gap. The data show that there are now about 5,000 jobs for cloud technology hiring, up 92% from a year earlier, and 4 times times higher than in 2010. Wanted Analytics said: "The demand for cloud-skilled talent has grown so fast that the gap between talent recruitment and the supply of talent in the US has become bigger and more difficult."

Cloud computing industry needs talent

Most cloud recruitment requirements come from cloud service providers. In the relevant recruitment last month, VMware released the largest number of 360. The second was Microsoft, 230, followed by Amazon.com,urs Corp. and Google.

Among them, software engineers, System engineers and network administrators are the highest technical skills required for the post, but also the most popular.

About One-fourth of jobs require candidates to know about cloud computing, but technical workers are not the only ones looking for cloud computing employers. Technology, they are looking for more resources. For example, leading unskilled workers, including marketing managers, sales managers, management analysts, and financial analysts required for cloud skills. These belong to the cloud service based marketing, or marketing services and other areas. Wanted Analytics analyst Carolyn Menz This analysis.

Pirate Bay throws "space program": Near-Earth orbit set up file server

The earth can't stop the Pirate Bay!

The Pirate Bay, the world's largest file-sharing website, announced today in a statement on its official blog that it would launch a small, low-orbital space station to place a file server in order to escape the blow from government agencies.

The Pirate Bay said in the article, the space station will be sent by unmanned aerial vehicles to the ground kohms meters from the near-Earth orbit, the server can carry a transmission rate of up to 100Mbps. The website believes that this will greatly increase the difficulty of government agencies to seize the server.

Due to alleged infringement of copyright, The Pirate Bay has been the Swedish and national police as a severe target, the server has repeatedly been raided. The overwhelmed Pirate Bay has finally made a difficult decision: to flee the earth and develop into space.

However, the website bluntly, has not yet made any plans for this goal. As envisaged, the space stations are only dozens of kilometres from the ground level. In contrast, the flight altitude between 8-kilometer to 12-kilometer, and China's Shenzhou series of manned spacecraft operating altitude generally more than 300 kilometers.

More surprisingly, the Pirate Bay at the end of the article also said, "will be stored in every corner of the Galaxy file." This is clearly not the category of science and technology, but entered the ranks of science fiction. As of now, the site is still inaccessible.

Who will be the next "Dropbox"? The game is still in progress.

It seems that every cloud storage company wants to be the next Dropbox.

It's easy to understand why they think so, Dropbox now boasts 50 million users, mainly providing cloud storage, file sharing, and real-time synchronization capabilities, and people are praising its cross-platform ease of use. Its success also prompted discussions about whether the San Francisco company, led by its CEO, Drew Houston, was an industry subversive or just a flash in the pan. At present, the main platform providers (Microsoft, Apple, Google) are doing their own cloud-based file sharing and synchronization products. VMware's Project Octopus and Citrix Acquisitions Sharefile are also considered to be products that will develop similar Dropbox functions.

But there are dozens of smaller, more flexible cloud storage providers that want to replicate "Dropbox" success in the marketplace. Box is the most prominent among these competitors, in addition to Egnyte, Accellion, owncloud, Grouplogic, Surdoc and other companies. Dropbox itself did not sit idly by, Dropbox just bought Cove to help build its infrastructure and service levels.
