Running head: PUA 421 FINAL Lee 1 PUA 421 Final In cloud computing, there are three types of services offered: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software-as-a-Service (SaaS). However, for the purposes of this paper, only PaaS and SaaS will be discussed. According to the Chief Information Officers (CIO) Council (2017), PaaS can be defined as a service that platform providers provide so that customers can create their own application, which means that platform providers need to give customers a platform with the capabilities and necessary components to create their desired applications. Depending on the components provided on a platform, customers may find that the PaaS they select allows them to create …show more content…
867). Understandably, offering SaaS services at a low price in comparison to traditional software means that profit margins are smaller, and these relatively lower profits make maintaining customers important for SaaS providers. PaaS, on the other hand, provides different uses and has a different developmental process. For instance, one important use of PaaS is that it allows for the development of SaaS, which often use these platforms to develop their services, and PaaS also allow third parties to develop their own SaaS applications without unnecessary complexity (Walraven et al., 2014, p. 669). As mentioned previously, PaaS providers also give customers the tools needed to create their own applications. However, the process can be further delved into. According to Holubek and Floyd (2013), PaaS vendors provide a platform that customers can develop with “a collection of application infrastructure (middleware) services,” such as testing, database services, programming languages, and interface design tools (p. 47). These middleware services allow customers to specifically develop their apps however they like, as long as the PaaS provider’s middleware services satisfy their needs.

PaaS: which stands for “Platform as a Service”. This type of cloud computing mostly used by programmers, application developers, or the companies who are in this type of business. PaaS provides set of tools and services to help developers code and run their programs without buying the expensive hardware and software layers. Most popular providers are: Google App Engine, Amazon Elastic Beanstalk, and Microsoft Azure OrangeScape.
SaaS, or Software as a Service, portrays any cloud administration where buyers have the capacity to get to software/programming applications over the web. The applications are facilitated in "the cloud" and can be utilized for an extensive variety of errands for both people and companies. Google, Twitter, Facebook and Flickr are all samples of SaaS, with clients ready to get to the administrations by means of any web empowered gadget. Endeavor clients have the capacity to utilize applications for a scope of necessities,
(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.
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
SaaS is the most widely recognized type of distributed computing for independent companies. You can get to web facilitated programming applications utilizing a program, as opposed to conventional applications put away alone PC or server. The product application have is in charge of controlling and keeping up the application, including programming updates and settings. You, as a client, have constrained control over the application and design settings.
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 . 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 . The last category Platform as a Service (PaaS) is used as a tool to develop software . All these services offered by Cloud Computing are done virtually where you access
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)
PaaS is a convenient tool for businesses, because it provides businesses with the necessary tools and opportunity to create and distribute their own applications, while using outsourced hardware for doing all the heavy lifting for them, rather than obtaining all of the necessary computer power themselves (Zhu, et al., 417).
In SaaS, applications are hosted by a vendor or service provider and made available via a network to clients, in most cases through the Internet. Platform as a Service (PaaS) is often used for providing operating systems and associated services via Internet which doesn’t require any downloads or installation by the client. Infrastructure as a Service refers to outsourcing the equipment that is used to support operations, such as hardware, servers and other networking pieces.
There is mix of niche and multi-industry could vendors in the market. One example of a niche industry-focused solution is Veeva, a provider of cloud based solution for medical representative in the pharma industry that has generated impressive growth and margins. One of the most important reason or the success was the competition that was present was only for on-premise technology and couldn’t compete with the more mobile and cloud solution, which was needed for this profile.
SaaS is becoming an increasingly prevalent delivery model as underlying technologies that support Web services and service-oriented architecture (SOA) mature and new developmental approaches, such as Ajax, become popular. SaaS is closely related to the ASP (application service provider) and On Demand Computing software delivery model
Software as a Service (SaaS) is the capability of users or consumers to use the provided application that runs over a cloud infrastructure. These services can be accessed from different users computers through Web browsers. LinkedIn is an example of the SaaS.
