This model provides services to users to access the infrastructure according to their need like servers, storage and network and pay for it accordingly. In IaaS there is no chance of failure occurred. Without internet IaaS is unusable. “IaaS” is used when you have your own software and platform and now you want purchase hardware to run it. Phase2 It is a model that provides services to users through web without installing any application on their PC. The price of “SaaS” is based on monthly or annual fee so it’s easy to buy this model. Because of this organizations access services at less cost. Without internet connection SaaS is not usable. In SaaS data is safe in cloud. Fig 1.2 Features of PaaS It is a model that provides users a platform in which they can manage verify and develop applications. PaaS is used when you developed your own software and now you want to run it on publicly available platform. Development is easier in PaaS for running the application we need only PC and internet connection. Step 3-Identify cloud computing matrix This framework is multidimensional but here we discuss three dimensions XYZ. The X dimension express the response time ranging from milliseconds, minutes, days, and beyond. The Y dimension represents the domain like IaaS, PaaS, and SaaS etc. The Z dimension represent planes and introduce a structure for monitoring and management the end to end events. The fig 1.1 depicts that multiple administrative domains are operating with a “SOA” based system. Governance as a service provides features to administrations and enables the users who are end users to produce and consume the data using different services.
