Cloud computing can also be separated into three broad categories of service: software as a service (SaaS), platform as a service (PaaS), and infrastructure as a service (IaaS). SaaS are applications that are typically run on remote computers that are owned and operated by a third-party; they connect to customers computers via the Internet. Examples would be, accounting software such as QuickBook on the enterprise side and services like Facebook or Google on the consumer side. The second category, PaaS is a platform for developers to design and build their own applications rather than use existing ones. These applications could range from a web site to a custom operating system. An example of a PaaS provider is Windows Azure Cloud Services. The third and final type of cloud offering is IaaS. IaaS is the actual nuts and bolts of computing hardware in virtual form. An IaaS provider such as Amazon Web Services (AWS) can offer their customers access to server farms that otherwise would be beyond their capability to operate.(Juve et al, 2013) Cloud computing, as it has come to be understood, is more than simply storing data remotely. It is instead, the idea of the technology itself
b. Software as a service or the SaaS : Cloud platforms that allow the clients to access several software modules and databases that are installed on the platform itself, are considered to use the SaaS model (He, Fan and Li 2013).
SaaS (Software as a Service) - On-demand software applications through a web browser, avoiding a need of full scale installation, maintenance and monitoring of software application platforms and its infrastructure.
SAAS (Software as a service) - Allows users to run existing online applications. Off-the-shelf applications are accessed via internet.
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
The SaaS model allows the user to use an application provided by the cloud provider, like a software application installed with the only difference that the application is delivered through internet. Many companies such as Microsoft, Autodesk and Adobe are moving towards this concept that
of organization, are discussed. Characteristics of cloud computing discussed to get idea what the cloud computing is all about using. In addition to that, deployment model of cloud computing is discussed in greater detail to explain cloud computing can be used as public, private or hybrid type. Based on service delivery cloud computing divided into three types Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS) are explained further in this section.
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.
Cloud computing provides a medium of depositing and sharing processed information to designate computers and other devices, either within or outside an organization in a secured way. Once the relevant data and files are uploaded through the internet, they can be accessed via computers, laptops, tablets, mobile phones etc by logging into a cloud service. The cloud service providers, who offer the cloud service, operate on the basis of pay as you use model and also the type of service model – Infrastructure as a service (IaaS), Platform as a Service (PaaS) and Software as a service (SaaS).The organization must familiarize itself with the pricing model to avoid high infrastructure costs. Each organization can choose the form of cloud service it requires based on its needs. Hence the different forms of
SaaS is a cloud computing model where the service provider is responsible for managing the entire cloud infrastructure, platform and is also responsible for the secure deployment and management of the customer-required applications such as office suite applications - that is why SaaS is sometimes referred to as “finished services” (Squicciarini, et al., 2016).
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 removes the need for you to be in the same physical location as the hardware that stores your data. There are number of functionally equivalent services in the cloud Due to unreliable internet connections different cloud applications may receive different levels of quality for same cloud services so that optimal service selection becomes important. Cloud computing provides three main services, namely Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). In Software as a Service (SaaS), Clients can use the software that is provided by the provider, which usually need not to be installed on their own machine and they can use the software
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
The three service models are Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS). The aptitude that SaaS gives to the user is to use the provider’s applications functioning on a cloud infrastructure. The applications are accessible from any connected client devices. The user does not do anything with the cloud
