Cloud Computing Providers and their Models

Discuss about the Cloud Computing for Data and Programs.

Cloud computing defines the process of storing and accessing data, programs through the internet instead of the hard drive of the computer (Dinh et al. 2013). The term cloud is just a metaphor for the internet. The cloud is not same as the hard drive of the computer, when the data are stored or the program is being run on the hard drive that is called the local storage and computing (Zissis and Lekkas 2012). In addition to this, the cloud computing is accessing the data in a very short time period.

In this report, we are describing the list of cloud computing providers, their utilized models, justification for selecting Windows Azure and comparison between the Windows Azure and Bluemix.

There are several reasons because of which here the Windows Azure is chosen for discussing the impact of the cloud computing. These reasons are mentioned below:

Message Orientation: The most crucial facility of the Windows Azure is the Message- Orientation. The web service operates with the help of the messages. The main focus is put on the processing and formation of the messages (Azure.microsoft.com 2016). The RPC system operate the messages by putting them into the subordinate part, unlike this system, the Windows Azure also operate the messages by making them strictly subordinate to the local programming. This is not applicable for the message format utilized for the message exchange (SOAP) but it also provides the description of the web services (WSDL) (Rittinghouse and Ransome 2016). There is remote procedure called as the metaphor to view the web service.

Protocol Composability: Protocol can be composed while it is being used in some combination or individually. In “Silos” there are several protocol designers who are interested to develop new protocols for the innovating something new in the technological world (Dinh et al.  2013). In case of the other web services, the domains are overlapped due to which the operation cost is increased and usability get hampered. Windows Azure doesn’t follow this aspect.

Cloud Service Model

There are three types of cloud service models utilized by IBM (Calder 2014). These models are: IaaS (Infrastructure as a service), SaaS (Software as a service), and PaaS (Platform as a service). Through the SaaS web service can be as commercial software, software can be managed from the inner location and software can be delivered from one to many models. PaaS is developed to maintain, host, deploy and test the applications in the same combined development environment (Huang et al. 2012). IaaS is developed to make the resources distributed as a service allows the dynamic scaling.

Explanation for choosing Windows Azure

In case of the Microsoft Web Services, they use only PaaS (Rittinghouse and Ransome 2016). The platform as a service provides the cloud service for development of the environment and this orientation of development provides a proper standard for the application developers.

The Windows Azure provides several services: web and mobile service, storage, data, intelligence, analytics, internet of things, networking operation, media, CDN etc. These services are provided by Microsoft are divided into several instances: Basic tier, Standard tier, Local SSD etc. Basic tier provides 0.75GB, 1.75 GB and 3.5 GB RAM for the cost of 0.02 dollar/hr, 0.06 dollar/hr and 0.12 dollar/hr (Azure.microsoft.com 2016). Whereas, IBM Bluemix services are classified as Hobbyist, Medium Business and Large enterprise, these start ups involves 300/second, 600/second and 10000/second HTTP requests at the range of 24 to 175 dollar (Console.ng.bluemix.net 2016).

There are several reasons for nominating the IBM Bluemix as the best cloud service provider:

Cloud is conventional: Cloud involves all the cloud computing layers (SaaS, PaaS, and IaaS) which make it more convenient for the business for achieving better flexibility in the market (Huang et al. 2012).

Micro- services architecture: This architecture provides the IBM Bluemix to deploy several complex architectures to independent one.

Rich option for reusable services: Reusability of software is main advantage of the IBM Bluemix, which make it more compatible than any other cloud services (Calder 2014).

Conclusion

Cloud computing has invented as a new technological advancement, which has benefitted the modern world from different perspectives. In this report it can be concluded that, the IBM Bluemix cloud service is the best services compared to the Windows Azure, as it provide more extended platform for the development. In addition to this, other advantages of IBM Bluemix are given in this report in contrast with the Windows Azure. The platform utilized by the IBM Bluemix makes it more effective in the sector of cloud computing.
