computing is the use of computing resources (hardware and software) that are delivered as a service over a network (typically the Internet). Cloud computing is the fusion of tradional calculation method,such as grid computing, distributed computing, parallel computing, utility computing, network storage, virtualization, load balancing, network technology. It aims to design an excellent system with powerful computing ability which is combined by many low price computing entities. 3 CONFIDENTIAL Cloud computing is the use of computing resources (hardware and software) that are delivered as a service over a network (typically the Internet).

is short for “Software as a service”. Software as a service ,sometimes referred to as "on-demand software", is a software delivery model in which software and associated data are centrally hosted on the cloud. SaaS is typically accessed by users using a thin client via a web browser. 5 CONFIDENTIAL Saas is short for “Software as a service”. Software as a service ,sometimes referred to as "on-demand software", is a software delivery model in which software and associated data are centrally hosted on the cloud.

challenges: 1. Since data is being stored on the vendor’s servers, data security becomes an issue. 2. SaaS applications are hosted in the cloud, far away from the application users. This introduces latency into the environment. 3. Some business applications require access to or integration with customer's current data. When such data are large in volume or sensitive (e.g., end users' personal information), integrating them with remotely hosted software can be costly or risky, or can conflict with data governance regulations. 4. And so on… 7 CONFIDENTIAL SaaS’s challenges: 1. Since data is being stored on the vendor’s servers, data security becomes an issue. 2.

is short for “Platform as a service”. Platform as a servic is a category of cloud computing services that provide a computing platform and a solution stack as a service. Along with software as a service (SaaS) and infrastructure as a service (IaaS), it is a service model of cloud computing. In this model, the consumer creates the software using tools and/or libraries from the provider. The consumer also controls software deployment and configuration settings. The provider provides the networks, servers, storage and other services. 8 CONFIDENTIAL PaaS is short for “Platform as a service”.

is short for “Infrastructure as a service”. In this most basic cloud service model, IaaS providers offer computers, as physical or more often as virtual machines, and other resources. IaaS clouds often offer additional resources such as images in a virtual machine image library, raw (block) and file-based storage, firewalls, load balancers, IP addresses, virtual local area networks (VLANs), and software bundles. 10 CONFIDENTIAL IaaS is short for “Infrastructure as a service”.
