Cloud Computing at a Higher LevelIn many ways, cloud computing is simply a metaphor for the Internet, the increasing movement of compute and data resources onto the Web. But theres a differ

Its about new programming models, new IT infrastructure, and the enabling of new business models.For those developers

Suns

Think of the existing cloud “islands” merging into a new, interoperable “Intercloud” where applications can be moved to and operate across multiple platforms.(2) High-densi

This high-density technology is being incorporated into our large-scale cloud designs. (3)Data in the cloud More than just compute uti

Suns Open Storage products offer hybrid data servers with unprecedented efficiency and performance for the emerging data-intensive computing applications that will become a key part of the cloud. These technology bets are focused on drivi

Why Cloud Computing?(1)Clouds: Much More Than Cheap ComputingCloud computing brings a new leve

Cloud computing begins as a way to improve infrastructure resource deployment and utilization, but fully exploiting this

Cloud computing is embraced as

11、a critical way to revolutionize time to service. But inevitably these services must be built on equally innovative rapid-deployment-infrastructure models. To be sure, these trends have existed in the IT industry for years. However, the recent emergence of massive network bandwidth and virtualization

It also creates new opportunities to build a better breed of network services, in less time, for less money.IT Efficiency on a Whole New ScaleCloud computing is all about efficiency. It provides a way to deploy and access everything from single systems to huge

14、amounts of IT resources on demand, in real time, at an affordable cost. It makes high-performance compute and high-capacity storage available to anyone with a credit card. And since the best cloud strategies build on concepts and tools that developers already know, clouds also have the potential to

For example, clouds allow for self-service provisioning through APIs, bringing a higher level of automation to the datacenter and reducing management costs.Eliminate over pr

17、ovisioning Cloud computing provides scaling on demand, which, when combined with utility pricing, removes the need to overprovision to meet demand. With cloud computing, companies can scale up to massive capacities in an instant.For those who think cloud computing is just fluff, take a closer look a

Already the bandwidth used by Amazon Web Services (AWS) exceeds that associated with their core e-tailing servic

New business functions are now just a script away.Accelerated cycles The cloud computing model provides a faster, more efficient way to develop the

21、 new generation of applications and services. Faster development and testing cycles means businesses can accomplish in hours what used to take days, weeks, or months.Increase agility Cloud computing accommodates change like no other model. For example, Animoto Productions, makers of a mashup tool th

Cloud computing can also provide a wider selection of more lightweight and agile development tools, simplifying and speeding up the development process.The immediate impact will be u

23、nprecedented flexibility in service creation and accelerated development cycles. But at the same time, development flexibility could become constrained by APIs if theyre not truly open. Cloud computing can usher in a new era of productivity for developers if they build on platforms that are designed

24、 to be federated rather than centralized. But theres a major shift underway in programming culture and the languages that will be used in clouds.Today, the integrated, optimized, open-source Apache, MySQL, PHP/Perl/Python (AMP) stack is the preferred platform for building and deploying new Web appli

Cloud computing will be the catalyst for the adoption of an even newer stack of more lightweight, agile tools such as lighttpd, an open-source Web server; Hadoop, the free Java software framework that supports data-intensive distributed applications; and MogileFS, a that enable

Its also about an emerging ecosystem of complementary service

And they continue to expand the levels of virtualization, a key architectural component of the cloud that offers ever-higher abstractions of underlying services.(3) How Did Cloud Computing Start?At a basic l

Almost all IT resources can be delivered as a cloud service: applications, compute power, storage capacity, networking, programming tools, even communications services and collaboration tools.Cloud computing began as lar

30、ge-scale Internet service providers such as Google, Amazon, and others built out their infrastructure. An architecture emerged: massively scaled, horizontally distributed system resources, abstracted as virtual IT services and managed as continuously configured, pooled resources. This architectural

31、model was immortalized by George Gilder in his October 2006 Wired magazine article titled “The Information Factories.” The server farms Gilder wrote about were architecturally similar to grid computing, but where grids are used for loosely coupled, technical computing applications, this new cloud mo

32、del was being applied to Internet services.Both clouds and grids are built to scale horizontally very efficiently. Both are built to withstand failures of individual elements or nodes. Both are charged on a per-use basis. But while grids typically process batch jobs, with a defined start and end point, cloud services can be continuous. Whats more, clouds expand the types of resources available , databases, and Web services and extend the applicability to Web and enterprise applications.At the same time, the concept of utility computing
