A year ago, in one of these transactions that will be remembered forever, Microsoft paid out 8.5 billion dollars and became owner of the company's largest market VoIP, Skype. With the growth of the company provided, Microsoft and Skype have made a change in the way it works all the management of users and connections, originally belonging to the architecture of P2P supernodes. These days it ran a rumor that Microsoft was using Linux for 10,000 servers to replace the model of P2P supernodes. ¿Linux servers hosted by Microsoft? Was it true?

From that day on which Microsoft signed the checks for the inclusion of Skype on devices like Xbox, Kinect, Windows Phone and connectivity applications such as Outlook, Xbox Live, Lync and even Bing have been promoting itself and evolve as Janus Friis and Niklas Zennström (founders of Skype, which they then sold to eBay) must be in some island paradise enjoying the pleasures untold. Lately, the Redmond company has turned upside down Skype's infrastructure and has made changes that really surprised at the extent and for at contradictory. How? Yes, because these days it ran a rumor that Skype P2P supernodes replaced its Linux servers hosted by Microsoft.

What did they do? Looks like a mouthful, but so far Skype working with a system based on what are called P2P supernodes, whose nuclei could support up to 800 users. This decentralized P2P system provided a solid infrastructure, but it was still a dangerous activity if it is related to the type of information passing through them, being in constant danger of malware attacks by the immense amount of users that has scaling leading VoIP service. Thus arose the hypothesis, an expert in security, Kortchinsky Kostya, who said that Microsoft had made available to 10,000 Linux machines that are hosted by them. These computers would be running a Linux distribution using grsecurity patch and package configurations designed for servers more resilient to attacks, as noted by Arstechnica site.



The strange thing is that at first glance you could tell they have these computers would be much more expensive as an investment for Microsoft, but as the theoretical maximum of supernodes classic was 800 users, each computer can accommodate 100,000 users, making the maintenance would be more centralized and inclusive. What was even stranger about the use of Linux on the part of Microsoft, who has repeatedly said that its main competitor is the open source system. But this was not the case. One day after everything was laughing Reddit Microsoft is attacking Microsoft, an employee of Skype announced the following:

As part of our ongoing commitment to continuously improve the user experience of Skype supernodes have developed that can be placed on dedicated servers in secure data centers. This has not changed the underlying nature of Skype with the use of P2P architecture, where the supernodes simply allow users to find each other (no calls go through supernodes). We believe this approach has immediate benefits in performance, scalability and availability for hundreds of millions of users who make up the Skype community.

And yes. Insofar as they give more information, we will be happy to tell you specifically how Skype is working these days, but what appears is that they have implemented the model explained by Kostya Kortchinsky, but without getting rid of the supernodes and apparently unused Linux, but do not specify
