IaaS is the foundation of all cloud services, with PaaS building upon IaaS, and SaaS in turn building upon PaaS as described in the Cloud Reference Model diagram. The cloud types, i.e public, private, community, hybrid also need to be considered. Each layer focuses IT functionality on supporting a specific area of concern and abstracts details of other layers. These can be categorized into three basic service models as listed below: ... SaaS model allows to use software applications as a service to end users. Cloud security ppt 1. Public cloud could also be less secure attributable to its openness e.g. 4 . How to choose a Technology Stack for Web Application Development ? By using our site, you Secure Systems Research Group - FAU 8/9/13 11 Approaches to security UML/OCL models Security patterns Model checking and Each element (we will call it a node) of a list is comprising of two items - the data and a reference to the next node. This is possible due to the elasticity of the cloud, enabling us to continuously optimize instance type mix and to grow and shrink our footprint near-instantaneously without the need to maintain large capacity buffers. Business Support Services provide the business-related capabilities needed to simplify and support the end-to-end business activities of an enterprise Cloud Ecosystem. The Model divides cloud-based application architecture into seven layers: Application, Transformation, Control, Instantiation, Appliance, Virtual, and Physical. The risk in a cloud deployment generally depends on the types of cloud and service models. Cloud computing is the next stage to evolve the Internet. Disadvantages: No longer in control. Data centers or cloud is management stage of data where data is managed and is used by end-user applications like agriculture, health care, aerospace, farming, defense, etc. Cloud security is the protection of data stored online from theft, leakage and deletion. The model is shown in Figure 2. 3 . In making cloud computing what it is today, five technologies played a vital role. The definitions and architectures come from the US Department of Commerce, where the National Institute of Standards and words, Cloud Computing has become a transformational factor in modern IT development. 1.
