    • 4. The term cloud is used as a metaphor for the Internet, based on how the Internet is depicted in computer network diagrams, and is an abstraction for the complex infrastructure it conceals Virtual server / Virtual machine Web hosting Storage system Development Data base Business application Office suite Web services Deployment business opportunities for defining services that can be offered on a pay-per-use basis SERVICES over the INTERNET Testing Reporting

      • Cloud computing is a style of computing in which dynamically scalable and often virtualized resources are provided as a service over the Internet.
      • Cloud computing can be loosely defined as using scalable computing resources provided as a service from outside the environment on a pay-per-use basis.
      • W ith the ability to virtualized servers (behind a hypervisor-abstracted operating system), storage devices, desktops, and applications, a wide array of IT resources can now be allocated
      • on demand .
      • Cloud computing consists of shared computing resources that are virtualized and accessed as a service, through an API.
      “ It’s a world where the network is the platform for all computing, where everything we think of as a computer today is just a device that connects to the big computer we’re building. Cloud computing is a great way to think about how we’ll deliver computing services in the future.” — Tim O’Reilly, CEO, O’Reilly Media

    • 7. Incremental Scalability. Cloud environments allow users to access additional compute resources on-demand in response to increased application loads. Agility. As a shared resource, the cloud provides flexible, automated management to distribute the computing resources among the cloud's users. Reliability and Fault-Tolerance. Cloud environments take advantage of the built-in redundancy of the large numbers of servers that make them up by enabling high levels of availability and reliability for applications that can take advantage of this. Service-oriented. The cloud is a natural home for service-oriented applications, which need a way to easily scale as services get incorporated into other applications. Utility-based. Users only pay for the services they use, either by subscription or transaction-based models. Shared. By enabling IT resources to be consolidated, multiple users share a common infrastructure, allowing costs to be more effectively managed without sacrificing the security of each user's data. SLA-driven. Clouds are managed dynamically based on service-level agreements that define policies like delivery parameters, costs, and other factors. APIs. Because clouds virtualizes resources as a service they must have an application programming interface (API).
    • 8. Availability of processing cycle and data storage, because the communication bandwidth is limited and expensive. On Demand allocation and de-allocation of CPU , storage and network bandwidth makes cloud computing more appealing to end users. Energy costs and climate change are the crucial deciding factors to choose the location of data center. Cloud Computing satisfies that goal. The Cloud is collaborative and integrating .  You can mash up new technologies with the help of cloud computing and incorporate disparate group of communities like customers, suppliers, interest groups. Cloud Computing is cost effective and provides better pricing model. It’s not just sales, but also after-sales service and support , including: lifecycle management teams ensures successful service delivery on 24/7 basis. Provides advanced tooling for service monitoring and management; portals for network and application performance. Cloud Computing offers vendor independence. Service providers are strategically keen on reaching as wide market as possible because customer base have wide range of requirements and preferences. ROI TCO
    • 9. Traditionally, grid computing have lacked the automation, agility and simplicity characterized by cloud computing. Virtualized infrastructures are available on-demand and capable of supporting multiple users, but lack the automation required for the self-managing, self-healing property of the cloud. Because hosting does not enable on-demand, elastic scalability, it cannot be considered cloud computing. on-premises software has sometimes come to be called 'old-style' software, although it is still the preferred model in some industries such as banking, finance, and defense, where the ability to supervise and secure data on premises that are locally owned or controlled is required.

      • Private clouds
      • Data protection
      • Service-level issues
      • On-demand infrastructure owned by a single customer who controls which application run and where
      • Owner of server, network and disk can decide which user are allowed to use the infrastructure
      • Public clouds
      • Run by thirds party
      • Different customer working on the cloud (infrastructure)
      • Application from different customers mixed on the cloud server, storage, network
      • Much larger than private cloud, offering ability to scale up and down on demand
      • Hybrid clouds
      • Combination of private and public cloud model
      • Can help to provide on-demand service within company
      • Distribution of application and processing resources between private and public cloud
    • 12. Cloud service providers tend to offer services that can be grouped into three categories: Infrastructure as a service ( IaaS ), Platform as a service ( PaaS ) and Software as a service ( SaaS )
    • 13. Resources delivered as a service Dynamic scaling Variable cost Multiple tenants Enterprise grade
    • 14. Key characteristics PaaS offerings include workflow facilities for application design, application development, testing, deployment and hosting as well as application services such as team collaboration, web service integration and marshalling, database integration, security, scalability, storage, persistence, state management, application versioning, application instrumentation and developer community facilitation. These services are provisioned as an integrated solution over the web.
    • 15. The on demand licensing enables the benefits of commercially licensed use without the associated complexity and potential high initial cost of equipping every device with the applications that are only used when needed. Low-cost way for businesses with business software to obtain rights to use software as needed versus licensing all devices with all applications. No IT staff needed – As subscription services the support, updates, upgrades, and maintenance is provided by the company that offers the service.  Low startup costs – Instead of investing in a bunch of hardware there is often a small setup fee or in many cases no setup fee at all.  Instead of purchasing the software , you are purchasing it as a service—which really means the right to use the software. System integration ensure airtight linkages with all manner of systems and critical business application (CRM, ERP, financial/billing systems) and third-party content

    • 17. 4 Choose The Right Cloud Provider User needs. Cloud provider must be able to deliver services with a high degree of accessibility and reliability to meet current and future user needs. Managing the Mass of Clouds. For an organization, cloud sprawl will mean having to manage a number of different service contracts with varying service-level agreements and performance metrics. Business needs. Understanding those agreements and then measuring the performance level of service engagements will be a logistical and managerial nightmare for businesses. Data protection. Cloud provider must have the necessary safeguards in place to protect data. Providers should conform to international standards for information security. In addition, other security measures should include network security including 256-bit encryption, documented and audited process security, and personnel security background checks. Flexibility to move in-house. Cloud provider should offer the flexibility to move data and configurations to an in-house deployment if customer so chose. Provider should have tools in place to accelerate the transition and offer the ability to move to an in-house environment easily. SLAs. Customer need the assurance of true service levels, that measure the availability of ability to use the service rather than simple infrastructure uptime commitments. The end-user service availability should be defined in vendor contract and should include financial penalties if those commitments are not met.

    • 31. Chris Roe, chief technology officer of QTRAX, an online music company, said, “Cloud computing is definitely changing how we test our Web sites forever.” With SOASTA’s CloudTest On-Demand service , customers receive a turnkey, hourly load testing service that includes all software, cross-cloud hardware and provisioning, testing support and real-time analysis and results reporting. SOASTA customers and partners simply provide the URL to be tested, and tests, monitoring and analysis can begin in hours. SOASTA CloudTest with BrowserFarm functionality is available now. For the next 90 days SOASTA customers can run a 500 browser user test for $500 , the company said. Solution example: SOASTA employed an iterative approach starting with a 1,000-user test. Generating load from Amazon EC2, they ramped the volume with each subsequent test – finally reaching the test goal of 200% of their anticipated peak – all while real customers accessed the production site at the same time. http://www.soasta.com/
