This case gives us a fundamental understanding of the concept of cloud computing and presents the advantages and issues of this IT infrastructure. This case gives a clear vision of the company’s current situation. Three main questions to consider

However, research focusing on the adoption of cloud computing technology and its impact on business operation is limited. This trend may be explained by cloud computing being a relatively new field. Available research on the structures, processes, security measures surrounding the cloud services are still at an early stage.

The ubiquitous cloud is changing our lifestyles, workplaces and business practices in ways that lead organizations to a new level of convergence and connectivity. Today, many organizations perceive cloud computing as a powerful driver of business transformation and revenue growth. In fact, while cost reduction is a great incentive, several other benefits also appear critical to business transformation. The cloud enables businesses to concentrate on their core competencies while cloud service providers create and run IT environments. Further, cloud enhances organizations’ agility by provisioning rapidly resources for business opportunities. Finally, virtual business processes that an organization creates on the cloud allow its stakeholders

(4) Platform as a Service - This offers a development environment as a service. You can use this technology to develop your own applications that run on the providers server.

Cloud computing is the result of evolution and adoption of existing technologies and prototypes; although the origin of the term cloud computing is unclear. In the earliest stages, the term ‘cloud’ was used to represent the computing space between the provider and the end user. References to cloud computing in its modern sense appeared as early as 1996, with the earliest known mention in a Compaq internal document (Regalado, 2011). In 1997, Professor Ramnath Chellapa of Emory University and the University of South California defined cloud computing as the new “computing paradigm where the boundaries of computing will be determined by economic rationale rather than technical limits alone”. This has become the basis of what we refer to today when we discuss

Cloud computing has become a major topic of discussion and debate for any business or organization which relies on technology. Anyone connected to the Internet is probably using some type of cloud computing on a regular basis. Whether they are using Google’s Gmail, organizing photos on an Apple iPhone’s photo steam or searching the Web with Bing they are engaged in cloud computing. The interesting thing about cloud computing is it did not start as a technology for the business enterprise, but was driven by the public with services like Facebook. Over the last few years businesses have started to see the value of cloud computing causing it to become a major technology solution for businesses and organizations around the world.

Platform as a Service is that providers supply services design, tools or Environment with IDE that make costumers able to develop software on it. Costumers don’t need to interact with operating system, their concern is writing application over provided platform. It usually used by software developer who wants to run their application over internet.

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

PaaS provides a software development and deployment tools over the web. It is targeted to software developers (plays a key role in DevOps). Like SaaS, it provides hardware on which applications can be ran on, with additional resources such as integrated development environments and development libraries. This model may need some level of configuration from the user to meet their requirements. (Sushil, et al., 2010, p. 61)

As with any new trend in the IT world, enterprises must figure out the benefits and risks of cloud computing and the best way to use this technology. The buzz around cloud computing has reached a fever pitch. Some believe it is a disruptive trend representing the next stage in the evolution of

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

The capability that is provided to the consumer is to deploy onto the cloud infrastructure consumer created or acquired applications created using programming languages, libraries, services, and tools supported by the cloud service provider. With the consumer not managing or controlling the underlying cloud infrastructure including network, servers, OS, or storage while the consumer does control the deployed applications and possibly configuration settings for the application hosting environment. (Peter Mell, Timothy Grance, The NIST Definition

The provision of standardised operating systems and application services (e.g. web server or database platform) delivered on IaaS services to enable customers to deploy and run their own applications

Platform As A Service (PAAS): provides clients with the capability of building and deploying services onto the cloud infrastructure such as operating systems, servers, storage and network without the complexity and cost of purchasing and managing the underlying software and hardware [5]. It also offers facilities for application development, application design, deployment, testing and hosting. That includes the scope of application services such as web service integration and marshalling, team collaboration, storage, database integration, scalability, security [5]. There are two dominant modes of PAAS service and they are as follows [6]:

c) Software-as-a-Service (SaaS): Software as a Service (SaaS) is a software distribution model in which applications are hosted by a vendor or service provider and made available to customers over a network, typically the Internet.
