As we learned in previous weeks, cloud computing services have three major different cloud architectures for different demanding customers. The three different architectures are Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). For the words of the name, we can see the obvious differences among these three architectures, which they provide different cloud services based on their specific cloud architectures. What are the differences among these three cloud services? What are the responsibilities for the cloud services providers? What are the responsibilities for the customers? The following will discuss about these questions.

Cloud computing is provided by an outside organization; it takes the place of an existing system, usually an internal network, and moves it to a web based service where all information in the company will be processed and stored. Internal IT infrastructures can be costly due to maintenance and personnel. Cloud computing reduces costs by removing the need for an internal system and the people to run it.

Cloud computing offers services to users based on on-demand self-service, broad network access, measured service, resource pooling and rapid elasticity; These characteristics promise a faster time for implementation, lower cost, superior scalability and a better end user satisfaction. These services are delivered in models known as Software As A service (SaaS), Platform As A Service (PAAS), and Infrastructure As A Service (IAAS). The first layer which is the Software As A service (SaaS) is the layer in which software applications are delivered to end users. Below is the Platform As A Service (PAAS) layer which offers a platform on which applications can be developed. The lowest layer is the Infrastructure As A Service (IAAS) layer, in this layer the physical servers and network infrastructure is offered as a service. These services can be deployed throughout the internet (Public Cloud Computing), on the intranet infrastructure, (Private Cloud Computing), in a shared community of private networks (Community Cloud Computing), or a hybrid of both (Hybrid Cloud Computing). The service deployment models are [8]:

Cloud computing reduces costs which helps provide businesses save on yearly expenses. A benefit of Cloud Computing is the Scalability factor, companies can start with one server reduce services to the bare minimum needed by the business. Then as the demand rises, they can then increase their cloud utilization to meet their new needs. “In addition, cloud computing is scalable. Traditional servers require expensive upgrades that cost a lot upfront. If your business doesn’t expand as much as you had hoped, that’s money you’ve wasted. Cloud service providers usually let you scale up and down seamlessly.” (Ismail, N, 2017)

Companies can remain agile and quickly build their systems with little delay. “One of the biggest advantages of a Cloud based system is that it can be easily set up in a very short period. The addition of new instances can be performed very quickly. In a cloud environment, software can easily be integrated. Hence, minimum effort is required to customize and integrate the applications.” (K. Pal, 2014).

Cloud computing is basically the use of large groups of resources linked together through networking to produce a lot of performances. One of the main purpose of this technology is the scalability that it offers. Indeed, when you need more speed or performances, the only thing to do is to add more servers to the cloud. It has a lot of advantages, but the most valuable one for a company is that they pay for what they use, and don’t have to buy some powerful servers “just in case” they will need more resource. This technology is a huge money-saver.

Cloud computing is a computing resource which provides service through internet. Cloud computing provides various service models such as Platform as a Service (PaaS) where developer can design, build and test application that run on cloud providers infrastructure. [1] Example: Google application engine, Software as a Service (SaaS) is

What is cloud computing? Cloud computing is a new process of managing, storing, and accessing data and programs over the internet instead of through a local computer hard drive or office network. (Griffith, 2016). A newer process developed in the early 2000’s to better help organizations as technology continues to evolve. Cloud computing is having the ability to access your information through an internet connection from anywhere at any time (Griffith, 2016). Of course, as with most all technology there are many advantages as well as disadvantages. Throughout this paper we will look at some of the top advantages and disadvantages that come with the process of utilizing cloud computing.

In the beginning a lot of talks were about what is the cloud? What does it do? What does it mean to us? Etc. But now the talks started to change and people are really thinking about how they can leverage the cloud, how they can use cloud as delivery model which is more efficient, how can they get services out faster, how can they use cloud with social media, with mobile, with data analytics. This period we are in a flexion point where we have really started using the cloud for advantage. When people want to talk about cloud computing the first thing they want to talk about is how they can save money in their IT environment and the reason is that they want to use the funds to drive innovation into delivering new applications and services instead of servicing the existing infrastructure. This is an opportunity to change the story of IT from tremendous cost. Instead of spending sixty, seventy or eighty percentage on maintaining the existing systems, organizations can flip the economic equation. A good example of how cloud allows businesses to grow is the telecommunication industry. The telecommunication industry have tremendous capacity, they have tremendous adjacency to clients and the cloud offers them the ability to bring new services to their clients more quickly, more efficiently and

Cloud computing is a computing resource which provides service through internet. Cloud computing provides various service models such as Platform as a Service (PaaS) where developer can design, build and test application that run on cloud providers infrastructure.[1] Example: Google application engine, Software as a Service (SaaS) where company host their data in cloud and user can access through internet. Example: Gmail, Facebook. Infrastructure as a Service (IaaS) is providing basic services. Cloud computing has four models first is public cloud services are available over a network that is open for

Cloud services provides flexible, elastic, and dynamic platform. 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).

The cloud is another word for the Internet. Traditionally, you have a computer with a hard drive where you save all your data and run programs from that computer (Griffith). With the cloud, you are saving files and using programs from the Internet, which allows you to use any computer with Internet access. The key advantage of cloud computing is scalability. This means that it adapts to your needs and workload. The main difference is when it comes to resources like software applications, storage space, etc., which have fixed capacities and upfront costs. Cloud computing allows you to only pay for what you need, avoiding unused capacities.

Mainly Cloud computing word is related to the concepts of the storage and the accessing of the data that was over the internet. With the usage of this cloud computing the growth in the business has been increased over the decade very high. On the client side there is no need to maintain the infrastructure and also there are many advantages of this cloud computing technology. By the usage of this model the cost will be saved and also the time will be. Service providers of the cloud computing will provide the different types of the delivery models and the deployment models and each model has its own services and features. Out of all the deployment models infrastructure as a service model is the best as it was offering its services based up on the pay per usage by the user and out of all the delivery models hybrid model is the best as it was having all the benefits of both the public and the private.

These private environments are made accessible via the Internet. Cloud computing provides services such as software (applications), platforms and infrastructures with a subscription-based in a pay-as-you-go model. These services are generally referred as Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS).

The cloud enables the data center to operate like the Internet and computing resources to be accessed and shared as virtual resources in a secure and scalable manner. Like most technologies, trends start in the enterprise and shift to adoption by small business owners.
