Cloud Computing: Cloud Service Providers Assessment Answer

Answer:

Introduction

Cloud computing is defined as a model which enables ubiquitous, on- demand access of network for sharing a pool of configurable resources of computing. In this report, Amazon is selected as a cloud-computing provider (Collins, 2014). The content of the report comprises of list of computing providers, their models, and justification for selecting Amazon as cloud computing provider and comparison of services provided by Amazon with Bluemix.

List of cloud computing providers and their models

Serial No.	Names of Cloud Service Providers	Provided Services	Models of Cloud service providers
1.	Amazon	Amazon Web services	1. 1.Platform as a Service 2. 2. Infrastructure as a Service
2.	IBM	1. IBM Cloud 2. IBM Bluemix Services (Ibm.com, 2016)	1. PaaS (Platform as a Service) 2. IaaS (Infrastructure as a Service) 3. SaaS (Software as a service)
3.	Google	Google Compute Cloud	PaaS (Platform as a Service)
4.	Microsoft	Microsoft Azure	PaaS (Platform as a Service)

Justification for selecting Amazon Web Services

There are several reasons behind selecting Amazon Web Services. The reasons are:

Performance: The most well-known services provided by Amazon are EC2 and Amazon S3. The power of Performance of AWS is in the storage (Amazon Web Services, Inc., 2016). The reliability of Amazon web services is better than Bluemix. The application is helpful in randomly powering down a component in the environment of Cloud Computing.

Security: For minimizing the effect of outages and for ensuring the robustness of the system it is geographically used. AWS uses an end-to-end approach in order to provide security and for hardening its infrastructure (Amazon Web Services, Inc., 2016). Virtual Amazon Private Cloud is provided by AWS, which is used for hosting the services on a network that is private. The network cannot be accessed from the internet.

Comparison and contrast between Amazon Web Services and Bluemix

Cloud Service Models

IBM Bluemix uses three types of cloud service models. The service models that they use are as follows:Platform as a service, Infrastructure as a service and Software as a service. IaaS gives basic resources of computing including networking, servers and data center space and many more. IaaS is considered as the foundation layer of IBM Bluemix. PaaS helps in providing a combination of platform and infrastructure software (Console.ng.bluemix.net, 2016). It includes application development that is cloud based, database software and hardware environment. Saas helps in providing network related access to network.

On the other hand Amazon Web services only use Paas and IaaS cloud service model. Amazon web services uses PaaS cloud service model for offering an environment of development to application developers (Amazon Web Services, Inc., 2016). They specially develop a standard for the development for distribution. The SaaS model is used for gaining access to application software and databases.

Services offered for Smart Application Model

Services offered for Smart Application Model	Amazon Web Services	IBM Bluemix
Internet of Things Application	· AWS IoT	· IoT for electronics · Internet of Things Platform · Context Mapping (YourStory.com, 2014).
Artificial Intelligent Application	Amazon Cloud introduces the service of Artificial Intelligent	Watson Services Introduces the service of Artificial Intelligent (Console.ng.bluemix.net, 2016).
Platform Design	Amazon web Services works on AWS platform (Amazon Web Services, Inc., 2016).	IBM Bluemix uses Cloud Foundry for Platform Design. It offers various plugin like Bluemix tool to integrate Eclipse development (Ibm.com, 2016)
Application Development	· Amazon API Gateway · Amazon Cloud Search · Amazon App Stream	· Data Cache · Session cache · WebSphere application server
Deployment Process	· Cloud Formation · Code Deploy · Ops Works	· Virtual Machine Deployment

Cost model

Amazon web services provide a number of services including storage, database, computing and many more. All the facilities provided by the cloud service provider helps the organization in moving faster. Pricing for all the applications are different and they does not have complex dependencies or requirement of licensing. For example GPU instances require $ 2.6 per hour (Amazon Web Services, Inc., 2016). On the other hand IBM Bluemix also follows various pricing strategies. For example NodeJS cost $24.15 (Ibm.com, 2016). For language Ruby Sinatra, $ 175.35 is charged by IBM Bluemix to large enterprises.

Application and Justification of Best Service provider

IBM Bluemix is the best service provider. This is due to the following reasons:

The most important advantage of IBM Bluemix is that if the runtime aren’t enough then one can build their own environment by using Dockers-Based Containers.
The composable service approach of IBM Bluemix helps an individual in kicking the tiers of new technologies like services of Watson (Ibm.com, 2016).
Virtual machine Deployment is used by IBM Bluemix that helps in controlling the entire stack of software (YourStory.com, 2014)
IBM Bluemix support hybrid cloud strategy which is not supported by Amazon web services.

Conclusion

It is concluded that Bluemix is the best provider. Both Amazon Web Services and IBM Bluemix uses Platform based and infrastructure based cloud service models but the virtual machine deployment in Bluemix helps in controlling the entire stack of software. Amazon web services uses PaaS cloud service model for offering an environment of development for application developers. It is concluded by analyzing the cloud service models used by both the providers. It is analyzed that IBM Bluemix uses Cloud Foundry for its platform designing while Amazon web Services works on AWS platform.
