If you take a look at the TOP500 list for the fastest computers in the world, it is dominated by Linux. Actually 98,3% af all computers is running Linux. That is 469 of 500. And in a couple of years there might NOT be any more than 1 or 2 Windows computers on the list. If you go back to last years Linux share it was 91,8% – so Linux continues to dominate the worlds market of the fastest computers and servers.
Microsoft has a fast computer on the list as number 10. It is a Windows HPC Server 2008. A part of the reason is that Microsoft cant deliver any programming tools for developing fast computers. When talking about fast the fastest servers is running more than 1 petaflop means 1026 quadrillion calculations per second. Intel does hold the record of the processors used as 75% of the TOP500 is from Intel. The other processor vendors is Sony, Cray, AMD and Sun.
In the coming years we will se more and more Cloud Computing systems which works as supercomputers because it is one of the cheapest ways to create a supercomputer. Actually you may use standard 19″ 1U Rack server to bundle many of these to a SKY which is the benefit of Cloud Computing. If you take 42 of these with 3 GHZ and 10GB memory and 4 TB disks, you will have SKY which have a 126 GHZ CPU, 420 GB Ram and 168 TB hard disk. The price for such a Rack Cabinet with 42 rack servers would be below 100.000 dollars.
Why is Linux so popular? First of all Linux is having around a 73% market share in the server market which is used in datacenters and hosting centers. Next Linux is of course free AND Open Source, but also scalable from start, so you may start with 1 rack server and have about 10 servers up running the next day, with Cloud Computing and / or Clustering with Automatic Process Failover and Load Balancing.
Cloud computing is the most important technology since WEB2. Cloud Computing is a hosting service and so called Internet-based “CLOUD” which use a number of rackservers or blade servers to provide one Unified Cloud. In such a unified Cloud you may have all your company’s or country’s software and data. Virtualization technology is used for many different operating systems and for safety you may ad unlimited Clustering technology with Load Balancing for automatic fail over for services. On the software part it uses SaaS, Software as a Service like on a normal LAN. As clients you may use PC, Notbooks, PDA and also thin clients. For Hosting and SaaS Providers The Virtual Private Datacenter can be delivered in just a few minutes.
According to Gartner Research:
“Cloud Computing will be as influential as E-business”
According to Gartner there is no doubt that Cloud Computing will change the way we use servers, and it will also be a more Green Solution to choose. According to IEEE Internet Computing “Cloud Computing is a paradigm in which information is permanently stored in servers on the Internet and cached temporarily on clients that include desktops, entertainment centers, table computers, notebooks, wall computers, handhelds, sensors, monitors, etc.” Some of the synonyms has been Grid Computing and Elastic Computing.
Cloudcenter facilities with IAAS
Cloud computing is a SaaS product for incorporation of “Software as a Service”, Web 2.0 and many other technologies and trends. Many of the known Cloud Computing companies like Amazon and Microsoft is now having trouble times ahead from the Open Source communities and the Server Hosting Center Providers. The Open Source Cloud Computing is making it possible to use your own systems for the Cloud Computing Sky.
Currently used systems is comparable and compatible with Amazons EC2, Microsoft, Grid Community and your own system backend with IAAS = InfraStructure As A Service.
