  “The Cloud” Astyle of computing where massively scalable (and elastic) IT-related capabilities are provided “as a service” to external customers using Internet technologies. Whatᾼ s new? Acquisition Model: Business Model: Access Model: Over Technical Model: Based on Based on pay for the Internet to ANY Scalable, elastic, purchasing use device dynamic, multi- of services tenant, & sharable

  “Components to Cloud Computing” Platform-As-A-Service(PaaS) Delivers a computing platform and/or solution stack as a service. Facilitates deployment of applications without the cost and complexity of buying and managing the underlying hardware and software layers. Infrastructure-As-A-Service (IaaS) The delivery of computer IasS, typically platform virtualization For example: • Virtual desktops • Grid computing

  “Components to Cloud Computing(contd.)” Applications-As-A-Service (AaaS) /Software-As-A-Service (SaaS) Leverages the Cloud in software architecture Eliminates the need to install and run the application on the customer's own computer Type: • Commercial • Government

  “Software as aService (SaaS)” Challenge SaaS Provider(s) • 3M+ user baseline, continually changing and growing • Manage software on “usage” basis • Dynamic requirements • Established negotiated prices • Software acquisition lead time • Include future versions/releases • Outyear capital projection for technology infusion • Provide maintenance and patches Examples • Enterprise Email • Host Based Security Solution • Back-up & recovery

  “Platform as aService Overview (PaaS)” Allow businesses to build and run web-based, custom applications in an on- demand fashion Developers have access to specific tools and libraries, while also controlling software deployment and configuration settings Paas service provides the networks, servers, and storage Customers have access to unlimited computing power, while decreasing upfront costs

  “Types of PaaSSolutions” The following list breaks down the four types of Platform as a service (PaaS) solutions: 1) Stand Alone Business Application Platforms- Development tools used to design and deploy software. This model has numerous benefits including advanced security, scalability, no additional hardware costs, and no software licensing fees. 2) Social Application Development Platforms- This type of platform is used to develop applications for social websites like Google+ and Facebook. This is done by integrating an Application Programming Interface (API) with the social website platform. 3) Web-Based Application Add-On Platforms- This type of Platform allows a user to modify and add features to existing Software as a Service (SaaS). 4) Open-Computing Platforms- This form of PaaS supports applications that are written in numerous types of code and that use any type of database, operating system, and server.

  “IaaS – Infrastructureas a Service” Its a provision model in which an organization outsources the equipment used to support operations, including storage, hardware, servers and networking components Characteristics and components of IaaS include: Utility Computing service andbilling model. Automation of administrative tasks.Dynamic scaling. DesktopVirtualization. Policy-based services. Internet connectivity.

  “Deployment models” Publiccloud Public cloud applications, storage, and other resources are made available to the general public by a service provider. Services are free or offered on a pay- per-use model. Amazon AWS, Microsoft and Google own and operate the infrastructure and offer access only via Internet
• 14.
  “Deployment models(contd..)” Private cloud ● Cloud infrastructure operated solely for a single organization hosted internally or externally. Undertaking a private cloud project requires a significant level Degree of engagement to virtualize the business environment, decisions about existing resources

  “Cloud Architecture” The systemsarchitecture of the software systems involved in the delivery of cloud Computing Typically involves multiple cloud components communicating with each other over a loose coupling mechanism such as a messaging queue. Elastic provision implies intelligence in the use of tight or loose coupling as applied to mechanisms such as these and others.
