Amazon EC2 cloud is made up of almost half-a-million Linux servers

Summary: Recent research indicates that Amazons EC2 cloud is made up of almost half-a-million serverseach of them running a variation of Red Hat Linux for their base operating system.

Almost half-a-million Amazon cloud servers run Linux every day.

We know that Linux on servers is big and getting bigger. We also knew that Linux, thanks to open-source cloud programs like Eucalyptus and OpenStack, was growing fast on clouds. What he hadnt know that Amazons Elastic Compute Cloud (EC2), had close to half-a-million servers already running on a Red Hat Linux variant.

Huang Liu, a Research Manager with Accenture Technology Lab with a Ph.D. in Electrical Engineering whose has done extensive work on cloud-computing, analyzed EC2s infrastructure and found that Amazon EC2 is currently made up of 454,400 servers.

While Amazon has never officially said what its running as EC2s base operating system, its generally accepted that its a customized version of Red Hat Enterprise Linux (RHEL). On top of that, for the virtual machines, Amazon uses the Xen hypervisor to host Linux; OpenSolaris; Solaris; Windows 2003 and 2008; and FreeBSD and NetBSD virtual machine instances.

Amazon also doesnt talk about how many servers their popular cloud is made up of, so Huang had to work it out. He explained, Figuring out EC2s size is not trivial. Part of the reason is that EC2 provides you with virtual machines and it is difficult to know how many virtual machines are active on a physical host. Thus, even if we can determine how many virtual machines are there, we still cannot figure out the number of physical servers. Instead of focusing on how many servers are there, our methodology probes for the number of server racks out there.

Huang continued, It may sound harder to probe for the number of server racks. Luckily, EC2 uses a regular pattern of IP address assignment, which can be exploited to correlate with server racks. We noticed the pattern by looking at a lot of instances we launched over time and running traceroutes between our instances.

Then Understanding the pattern allows us to deduce how many racks are there. In particular, if we know a virtual machine at a certain internal IP address (e.g., 10.2.13.243), then we know there is a rack using the /22 address range (e.g., a rack at 10.2.12.x/22). If we take this to the extreme where we know the IP address of at least one virtual machine on each rack, then we can see all racks in EC2.

By itself, though, thats not enough. You could use try to use port-scanning to work ot how many servers there are, but that would violate Amazons terms of service. So instead, since each Amazon Web Services (AWS) instance also has an external IP address. we can leverage DNS translation to figure out the internal IP addresses.

With that data, he was able to work out the number of server racks. With this he then just multiplied by the number of physical servers on the rack. Unfortunately, we do not know how many physical servers are on each rack, so we have to make assumptions. We assume Amazon has dense racks, each rack has 4 10U chassis, and each chassis holds 16 blades for a total of 64 blades/rack.

Private SharePoint Cloud Beats Other Cloud Hosting Options for Enterprises, Says AISN

Chicago, IL (PRWEB) March 16, 2012 – Public SharePoint Cloud is out and Private SharePoint Cloud is in. Those are the latest words of wisdom from SharePoint cloud hosting expert Jay Atkinson, who said today that when it comes to hosting Microsoft SharePoint 2010 for a large organization, a private cloud environment is the only way to go based on sheer practicality and bang-for-the buck.

Atkinson, who is CEO of hosting pioneer AIS Network, said that his company is now deploying the SharePoint Server 2010 platform in a single private cloud for significantly less than competitors charge to implement it in a public cloud or a hybrid cloud.

Plain and simple, you want the most control over your SharePoint 2010 environment with the least hit to your organizations bottom line, and you get every bit of that and more by moving from a traditional deployment to a hosted private cloud architecture, said Atkinson.

Currently, hosting providers are steering enterprise-class SharePoint 2010 customers toward public cloud and hybrid cloud hosting models. Our cost analysis research shows that those deployment approaches are needlessly costing more than they should and the customer sacrifices control at multiple levels.

A private SharePoint cloud is simply more economical and easier to manage for a large organization with security and compliance concerns, Atkinson said. An enterprise SharePoint Server 2010 platform implemented wholly in a private cloud, including the online storage components, exceeds core compliance requirements and surpasses the benefits of a public cloud or hybrid cloud.

With SharePoint 2010 deployed entirely in a private cloud, Atkinson said the customer gets:

* a hosted environment that is exclusively internal to the organization, * complete control of its servers, security, permissions, policies and customization, * seamless federation between line-of-business systems and various data sources, * quick scalability for system resources, and * the ability to move other core applications and platforms to the same private cloud.

Public cloud services like Microsoft Office 365s SharePoint Online and deployments of SharePoint Server 2010 in a public or hybrid cloud are okay for small to mid-size businesses, but theyre very impractical when it comes to serving the best interests of a large business, said Atkinson.

The private SharePoint cloud model is an ideal outsourcing alternative. Sooner or later, global and large enterprises evaluating SharePoint 2010 deployment platforms are going to realize that an enterprise SharePoint Server 2010 platform implemented solely in a private cloud is the only way to go.

Within the last two years, AIS Network has doubled in size and opened a second office. Last month, the company reported that customer demand for cloud computing had compelled it to double the size of its public cloud.

Linux servers keep growing, Windows & Unix keep shrinking

Summary: 2011 saw, according to IDC, Linux servers grow while Windows and Unix servers numbers shrank. In 2012, Linuxs server future looks brighter than ever.

Linux servers are soaring.

In 2011, we saw, according to IDCs latest Worldwide Quarterly Server Tracker, factory revenue in the worldwide server market grew for Linux while it shrank for Windows and Unix. What I find especially interesting about this is that IDC doesnt measure when you or your company install Linux on a bare-metal server or a re-purposed server, which is historically how Linux got into companies, but only servers with Linux already pre-installed.

That means more and more customers are asking IBM, HP and Dell, the big three server hardware vendors, for Linux on their hardware. Specifically, IDC found that Linux server demand was positively impacted by high performance computing (HPC) and cloud infrastructure deployments, as hardware revenue improved 2.2% year over year in 4Q11 to $2.6 billion. Linux servers now represent 18.4% of all server revenue, up 1.7 points when compared with the fourth quarter of 2010.

Its competitors? Windows server demand subsided slightly in 4Q11 as hardware revenue decreased 1.5% year over year. Quarterly revenue of $6.5 billion for Windows servers represented 45.8% of overall quarterly factory revenue, up 2.6 points over the prior years quarter.

As has long been the case, Unix is the server operating system that really got knocked around. Unix servers experienced a revenue decline of 10.7% year over year to $3.4 billion representing 24.2% of quarterly server revenue for the quarter. IBM grew Unix server revenue 2.5% year-over-year and gained 7.9 points of Unix server market share when compared with the fourth quarter of 2010.

What that translates into is fourth-ranked Oracle experienced a year-over-year revenue decline of 11.5% in 4Q11 to a 5.2% share of market while Fujitsu, ranked number 5, experienced a 10.5% decrease in factory revenue holding 3.4% revenue share in 4Q10. While Oracle also has a Linux distribution for IDCs hardware server measurement purposes, Oracle and Fujitsu saw their income go down as their Solaris Unix-powered systems continue to decline.

As Jim Zemlin, chairman of The Linux Foundation observed in his blog, IDC attributes some of that Linux success to its role in what the analyst firm calls density-optimized machines, which are really just white box servers, and are responsible for a lot of the growth in the server market. These machines have gained popularity in a space still squeezed on budget and that continues to be commoditized. But there are other factors at play for Linuxs success over its rivals.

These are, Zemlin wrote, Our latest survey of the worlds largest enterprise Linux users found that Total Cost of Ownership, technical superiority and security were the top three drivers for Linux adoption. These points support Linuxs maturity and recent success. Everyone is running their data centers with Linux. Stock exchanges, supercomputers, transportation systems and much more are using Linux for mission-critical workloads.

In addition, Linuxs growth owes a lot to the accelerated pace by which companies are migrating to the cloud. Long a buzzword, the cloud is getting real, right now. While there is still work to do for Linux and the cloud, there is no denying its dominant role in todays biggest cloud companies: Amazon and Google to name just two.

Saving File On Internet – Cloud Computing – Video


15-03-2012 03:10 How to save file on internet ? What is Cloud Computing ? Cloud computing is the delivery of computing as a service rather than a product, whereby shared resources, software, and information are provided to computers and other devices as a utility (like the electricity grid) over a network (typically the Internet).[1] Cloud computing provides computation, software applications, data access,data management and storage resources without requiring cloud users to know the location and other details of the computing infrastructure. End users access cloud based applications through a web browser or a light weight desktop or mobile app while the business software and data are stored on servers at a remote location. Cloud application providers strive to give the same or better service and performance than if the software programs were installed locally on end-user computers. At the foundation of cloud computing is the broader concept of infrastructure convergence (or Converged Infrastructure) and shared services.[2] This type of data centre environment allows enterprises to get their applications up and running faster, with easier manageability and less maintenance, and enables IT to more rapidly adjust IT resources (such as servers, storage, and networking) to meet fluctuating and unpredictable business demand.[3][4]

Amazon’s Web Services Uses 450K Servers

Amazons cloud computing operation is estimated to use at least 454,000 servers in seven data center hubs around the world. Data on the matter was offered by Accenture Technology Labs, as Amazon Web Services has yet to disclose details on its infrastructure.

Huan Liu, a research manager at Accenture, analyzed Amazons EC2 computing service using internal and external IP addresses he then extrapolated, came up with estimates on the number of racks in each data center location and took into account the number of blade servers per rack, to come up with his numbers.

Interestingly, Lius data shows the concentration of Amazon IP addresses in Northern Virginia, where Amazon keeps several data centers. Liu figures that there are 5,030 data racks in Northern Virginia, roughly 70% of all racks consisting Amazon Web Services. The Amazon U.S. West region in Oregon has only 41 data racks.

Lius estimates easily put the size of Amazons data structure well above the hosting providers that have publicly disclosed their server counts, but still at about half the estimated 900,000 servers in Googles data center network.

New estimate pegs Amazon's cloud at nearly half a million servers

It’s no secret that Amazon’s Elastic Cloud Compute (EC2) cluster is big. It powers massive services such as Netflix, Instagram, and Reddit. But just how big is anyone’s guess. The retail giant won’t say. So, dissatisfied with the company’s silence, one man decided to find out.

Huan Liu, a researcher with Accenture Technology Labs, crunched the numbers, and according to his estimates, Amazon Web Services (AWS) boasts just under half a million servers445,000 to be exact.

That may still be a guess, but it’s certainly an educated one. Mr. Liu used a process called DNS translation to map out the internal IP addresses of each active AWS instancemade possible, in short, because EC2 publishes all public IP addresses used.

As of March 12, 2012, Mr. Liu estimates the US East data center, based in Virginia, is the largest in size, with 5,030 server racks. Assuming that each rack boasts 64 blade serversan educated guess, as there’s no way to know for surethe total would amount to 321,920.

Mr. Liu was also interested in mapping the growth of Amazon’s cluster over the past six months, as an indication of the cloud computing industry’s overall health. From August 23, 2011 to February 23, 2012, Mr. Liu observed that the US East data centerwhich suffered an outage last Apriladded roughly 110 server racks each month.

For comparisons sake, thats more than Amazons entire So Paulo centre in Brazilthe company’s smallestwhich Mr. Liu estimates to have just 25 racks. However, while the growth rate looks roughly linear, Mr. Liu wrote on his blog, recently it is showing signs of slowing down.

Its important to realize that Mr. Lius results, while precise, are still based on assumptions; he admits it is possible that other AWS services, such as S3, SQS and SimpleDB, could run on dedicated racks, which would exempt them from his calculations. Also, if there was no active instance on a rack, it would not be counted in Mr. Lius results.
