What Are The Three Cloud Service Models?

As previously mentioned, cloud computing has recently emerged as a pioneering model for hosting and distributing services over the Internet. Actually, the model entails sharing resources on a huge scale through a value effective and location independent process. While the resources on the cloud are deployed by the seller, they are utilized by the consumer (Belamkar, 2014). Cloud computing is very beneficial to organizations and companies because it is engaging to business organizations

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).

Another type of cloud is the public cloud. This type of cloud is open to the public or it could be a large consumer who owns the cloud and is offering the services to consumers for a price. The last type of cloud is the hybrid. A hybrid cloud can both be private and community. The clouds are tied together but are still separate. The clouds share data and application portability.

Cloud computing can be the ability to use applications on the Internet that store and protect data while providing a service anything including email, sales force automation and tax preparation. It can be using a storage cloud to hold application, business, and personal data. Some people even arguing that anything we consume outside the firewall is "in the cloud," including conventional outsourcing.

This type of public cloud computing provides applications through the internet. Most of the enterprise application follows SaaS model. This model provides both extensive configuration and also the development environment where the customers can code and make modifications and additions.

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

In 2006 Eric Schmidt Google’s CEO used the term cloud to describe the business model of providing services across the internet. Since then cloud computing has become the most popular IT standards. It is used by various organizations to consume shared computing and storage resources in less time and reduced cost.

Platform as a Service (PaaS) provides a client with a platform that enables to develop, run, and manage applications. Additionally, a provider controls the infrastructure,

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

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.

In 1999, Salesforce.com became the first web service to deliver applications and software over the internet. This service eventually led the way to the cloud. In 2006, Amazon unveiled its own cloud computing platform called Amazon Web Services or AWS. The Amazon Web Service now provides online services to other websites and client-side applications and powers hundreds of thousands of startups and larger companies in over 1190 countries worldwide (Fee, 2013). After Web 2.0 was developed in 2009, other companies started their own cloud services. The cloud is used by consumers daily on many different outlets such as: social media applications like Instagram and Pinterest, Google Apps, Apple iCloud, Microsoft OneDrive, and much more. Now, any time you store information without using up your smartphone or your computer’s internal data, you are storing information on the cloud. The National Institute of Standards and Technology (NIST) defines cloud computing as a computing storage system that provides on-demand network access for multiple users and can allocate storage to users to keep up with changes in their needs (Nelson, Phillips, Steuart, 2015). The cloud has three levels: Software as a service (SaaS), Platform as a service (PaaS), and Infrastructure as a service (IaaS). With Software as a service, applications are delivered by the internet. An example of this would be Google Docs, where data is stored in the cloud and files

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 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

Infrastructure as a service is another type of cloud service. IaaS “are self-service models for accessing, monitoring, and managing remote data center infrastructures, such as compute (virtualized or bare metal), storage,

Cloud computing security or, more simply, cloud security refers to a broad set of policies, technologies, and controls deployed to protect data, applications, and the associated infrastructure of cloud computing. It is a sub-domain of computer security, network security, and, more broadly, information security [1]. With the extensive use of virtualization technologies combined with self-service potentialities cloud service providers are providing services to their customers through the Internet. In these service provider surroundingses, virtual machines from different multiple organizations have to be co-located on the same physical server in order to optimally maximize the effectiveness and efficiencies of virtualization.
