Cloud Computing at a Higher Level In many ways, cloud computing is simply a metaphor for the Internet, the increasing movement of
2、 compute and data resources onto the Web. But theres a difference: cloud computing represents a new tipping point for the value of network computing. It delivers higher efficiency, massive scalability, and faster, easier software development. Its about new programming models, new IT infrastructure,
3、and the enabling of new business models. For those developers and enterprises who want to embrace cloud computing, Sun is developing critical technologies to deliver enterprise scale and systemic qualities to this new paradigm: (1) Interoperability while most current clouds offer closed platforms an
4、d vendor lock-in, developers clamor for interoperability. Suns open-source product strategy and Java principles are focused on providing interoperability for large-scale computing resources. Think of the existing cloud “islands” merging into a new, interoperable “Intercloud” where applications can b
5、e moved to and operate across multiple platforms. (2) High-density horizontal computing Sun is pioneering high-power-density compute-node architectures and extreme-scale Infiniband fabrics as part of our top-tier HPC deployments. This high-density technology is being incorporated into our large-scal
6、e cloud designs. (3)Data in the cloud More than just compute utilities, cloud computing is increasingly about petascale data. Suns Open Storage products offer hybrid data servers with unprecedented efficiency and performance for the emerging data-intensive computing applications that will become a k
7、ey part of the cloud. These technology bets are focused on driving more efficient large-scale cloud deployments that can provide the infrastructure for next-generation business opportunities: social networks, algorithmic trading, continuous risk analysis, and so on. 2. Why Cloud Computing? (1)Clouds
8、: Much More Than Cheap Computing - 2 - Cloud computing brings a new level of efficiency and economy to delivering IT resources on demand and in the process it opens up new business models and market opportunities. While many people think of current cloud computing offerings as purely “pay by the dri
9、nk” compute platforms, theyre really a convergence of two major interdependent IT trends: IT Efficiency Minimize costs where companies are converting their IT costs from capital expenses to operating expenses through technologies such as virtualization. Cloud computing begins as a way to improve inf
10、rastructure resource deployment and utilization, but fully exploiting this infrastructure eventually leads to a new application development model. Business Agility Maximize return using IT as a competitive weapon through rapid time to market, integrated application stacks, instant machine image depl
11、oyment, and petascale parallel programming. Cloud computing is embraced as 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. Ho
12、wever, the recent emergence of massive network bandwidth and virtualization technologies has enabled this transformation to a new services-oriented infrastructure. Cloud computing enables IT organizations to increase hardware utilization rates dramatically, and to scale up to massive capacities in a
13、n instant without constantly having to invest in new infrastructure, train new personnel, or license new software. 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 Scale Cloud computing is all about efficiency.
14、It provides a way to deploy and access everything from single systems to huge 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 conce
15、pts and tools that developers already know, clouds also have the potential to redefine the relationship between information technology and the developers and business units that depend on it. Reduce capital expenditures Cloud computing makes it possible for companies to convert IT costs from capital expense to operating expense through technologies such as virtualization. Cut the cost of running a datacenter Cloud computing improves infrastructure utilization
