The Cloud Of Cloud Computing

purposes of this paper, only PaaS and SaaS will be discussed. According to the Chief

There are three standard service models: Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS). IaaS is when the cloud

A hybrid Cloud Deployment model with a combination of Public, Private and Community models will be used. The Cloud Service Delivery model will be a combination of SaaS, PaaS and IaaS to satisfy the requirements of the multiple business units within the organization, customers, and suppliers resulting in a cost reduction through optimized and efficient computing

Platform as a Service (PaaS) is an application development and deployment platform delivered as a service to developers over the Web. It facilitates development and deployment of applications without the cost and complexity of buying and managing the underlying infrastructure, providing all of the facilities required to support the complete life cycle of building and delivering web applications and

PAAS (Platform as a service) - Allows users to create their own cloud applications using supplier specific tools and languages.

Cloud computing is a fairly new technology; it is separated into three separate categories. The first is Infrastructure as a Service (IaaS) this service is mainly used by companies to cut the cost of buying computer hardware such as servers , they also save on maintenance cost since the virtual servers is maintained by the company that rents them [1]. The second category is Software as a Service (SaaS) this service deals with providing software which is usually rented, this allows users to have multiple users whereas normal software limits the amount of users [1]. The last category Platform as a Service (PaaS) is used as a tool to develop software [1]. All these services offered by Cloud Computing are done virtually where you access

Platform as a Service (PaaS) provides a platform and environment to allow developers to build applications and services over the internet (Interoute, n.d). Combined with Infrastructure as a Service (IaaS), developers can scale or modify resources in a short amount of time to make development easier, for example by increasing the number of servers available for testing. This later becomes useful when the solution is deployed, as the resources can be scaled up or down depending on how successful the development is.

There is wide range of services that could be provided by cloud providers. Based on blabla, there are 3 models of cloud services that widely popular. They are Infratructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). IaaS provides for fundamental resource for computing such as processing, servers, storage, networks and manage its physical infrastructures but costumers have control for their OS [fn1]. PaaS provides design, tools or Environment with IDE. It is usually used by software developer who wants to run their application over internet. SaaS delivers ready-use software over internet or we can called as web-based software. Cloud users neither have to maintain platform or infrastructures. These days this services gain money from advertising or user list sales for example Google mail service so users can enjoy it free.

PaaS provides sets of services and workflows that targets developers, who can use shared tools, technologies, processes and APIs to fast

Cloud computing is Internet-based computing, whereby shared information, resources, and software, are provided to terminals and portable devices on-demand. It is a rapidly developing and excellent promising technology. Cloud computing is the product of the combination of grid computing, distributed computing, parallel computing, and ubiquitous computing. Cloud Computing model has enabled IT organizations to serve the users globally. It gives the services like Platform as a Service, Software as a Service and Infrastructure as a Service without users being much aware of the details in which the services are provided.

Platform as a Service (PaaS): In this service, they provide you a platform software to develop or build applications.

Cloud computing includes web-based email systems and social networking sites like Gmail, Hotmail, Facebook and Linked In to name a few.

provides an application or development platform in which Cloud customers can create their own application. More precisely, they provide a set of API that can be used by developers to program or compose applications for the Cloud.

In this century, Internet is on the edge of another revolution, where resources are globally networked and can be easily shared. Cloud computing is in the focus that uses the Internet as a large repository where resources are available to everyone as services.[5]. many people prefer cloud services for its flexibility,versatility,anywhere accessibility of the services through internet.

Platform as a Service (PaaS) is where vendors (ex. Google and Microsoft) provide servers, tools, and utilities to allow the creation of applications capable of being deployed on the internet. Users manage the applications deployed and some environment settings but not the cloud network, O/S, or servers. The only hardware required for this model is a device to connect to the service.
