Cloud Computing Services

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

c. Platform as a service or the PaaS: Such services allow the clients to utilize developmental environments to design software applications.

Cloud computing enables businesses to deploy or subscribe to services as it needs them. A cloud features self-service, broad network access, centralized shared resources, and measurement of service usage. There are three widely accepted types of cloud service models. They are Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). Each serves a different purpose and business may choose to use just one, two, or even all three of the cloud types simultaneously as the needed.

PaaS (Platform as a Service) - Network Storage nodes and instances of Software development and hosting platforms are accessed over a remote length.

By 2020, Forbes (McKendrick, 2012) has estimated that the cloud market will be worth $270 billion; this suggests that the market is expanding rapidly and users are becoming more aware of this feature. Many people, though, still ponder over the exact purpose of cloud computing: Cloud computing is a group of offline servers that are networked together to allow data to be stored centrally. For example, Drop box is an established cloud storage company that allows users to store documents, images and videos on their servers. This type of cloud computing is known as ‘Software-as-a-Service’, which are business applications that are hosted by the provider and delivered as a service (Hurwitz, 2010). Hurwitz also mentions two other types of cloud computing: ‘Platform as a Service (PaaS)’ and ‘Infrastructure as a Service (IaaS)’. ‘Platform as a service’ is where the consumer will create an application, using tools and software from the provider, then the provider will administer the consumer with networks, storage and servers. ‘Infrastructure’ as a service is where the provider will provide the consumer with physical computer or virtual machine.

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

The PaaS model is particularly oriented towards developers, who need to run their applications without having the need to configure an entire network architecture of VMs and manage multiple application updates and upgrades. This delivery model allows developers to manage only their code and the data structures, everything else (runtime, OS, VMs, VMMs, networks,...) is then managed by the cloud provider.

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.

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).

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

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

Cloud computing also offers three kind of services: Software as a service (SaaS), Infrastructure as a service (IaaS), and Platform as a service (PaaS). The first one is software as a service; it is a single application on the internet to be used by all people. On the client side, it requires no investment into running servers needed on the other side. This service also requires less maintenance and is cheaper. Some applications that use this service are Hotmail, Google Apps, Skype, and other 2.0 applications.
