Cloud Computing with PaaS

The concept of cloud can be considered as one of the sectors, which is continuously innovating. There are different types of architecture can be implemented into the concept which makes the working of the cloud computing more goal oriented based service. The architecture can be implemented according to the requirement of the service and the payment would be based on the actual service, which is gained from the concept. It does not have a fixed payment mode. One of the advantage which can be achieved from the concept is the deployment of the application process is made faster and relatively easier in the concept of cloud computing relating to other traditional processes.

The main aspect, which is discussed in the report, is to take into consideration the aspect of platform as a service. Taking into focus the different Platform as a service concept one of the providers are broadly differentiated with the Bluemix and the justification of the concept is done using the platform as a service. 

The platform as a service can be used for the concept of maintaining, developing and testing of the network, sever, operating system, virtual machine and network and many more on the concept of paid on a rental basis. The following list provides a basic overview of the list of service providors relating to the platform as a service:

• Amazon bluemix – capable of full filling the concept of the requirement relating to hybrid cloud requirement.
• Amazon web service – supports server side technology, multiple languages and database.
• Microsoft Azure – offers different types of control due to the implementation of the Paas and IaaS.
• Google app engine – risk reduction process
• Cloud Foundry – PaaS service which is open sourced
• Engine Yard – Better virtual machine control

The cloud provider, which is taken into consideration, is the Amazon web service. The justification of the selection is given below in few points:

Justification 1: The main reason for the selection of the AWS is that it is a platform as a service approach and can be differentiated with the concept of bluemix with taking into consideration the operation, which is involved.

Justification 2: The AWS can be implemented quite easily and the working, which is related to the model, is quite easy as compared to other models.

The AWS and the bluemix are both cloud computing parts which have independent role of the own. The services, which are used, would be directly dependent on the need of the organization who would be implementing and using the service. The bluemix is a software, which is open source and can be used by any primary user. The concept, which is related to the Hub, can be considered as one of the options for the developers, which can help in the concept of achieving synchronized code from a distance and test it directly.

Platform as a Service with Bluemix

The concept of the Amazon web service can be considered one of the most professional approach with the use of cloud computing. The concept directly gives sufficient amount of service flexibility. This concept can be applied to any sort of business orientation. Most of the organization take into consideration the model due to the factor of decreasing and increasing run time environment. The charge for the concept would be applicable according to the usage which is done of the model. 

The concept of the platform as a service can be applied to different type of business areas. The different concept for example artificial intelligence, internet of things can be deployed in the level of professional expertise. The PaaS model directly helps in bypassing the concept of investment and the maintenance sector. 1750

The navigation and design of the concept mainly decides the comfort ability towards the user who would be using the different features of the system. Hence it can be stated here that the service provider should have a sound knowledge about the concept of design and navigation. A system that is basically designed contains certain type of components to be reused and combine that can be used for the building of the interface of the user. Bluemix focus on the same concept and has the system designed in a way of making the aspect very much user friendly so that anyone can use the system. However the system has some of the issue which is relating to the navigation part. The issues, which are majorly seen, are interface and login problems. The swatches, which are large in the user interface, are owned for the concept of issue relating to consistency with the design and the individual services. The design language, which is related to the blumix, provides a framework of the product. On the other hand, the concept of the amazon AWS offers interface which is relatively superior that is directly preferred by the users and the concept of the design is also very much simple. For the concept of the managing of the application relating to the architecture life cycle, this tool can be one of the most important relating to the use of the AWS design pattern. The user in this way would be able to better identify the requirement, services and the implementation plan that can configure the concept of the EC2, Cloud Formation, S3, VPC and IAM

Platform as a Service with AWS

AWS

The deployment of the “Hello World” application in the concept of the AWS as described in the official website of the service providers have been discussed in the following steps.

Step 1: launch of the server window of the Amazon EC2

In this step, the user needs to create a tag key by “name” and the value, which is of “CodeDeployDemo”

Step 2: Deployment of the source content, which need to be configured

To create the Amazon-S3 bucket (CLI), it is required to call the ‘mb’ command by the name of “codedeploydemobucket”. 

To create the console Amazon-S3 bucket, the steps shown in the image should be followed:

Calling the command ‘create-application’ to register the new application by the name of ‘HelloWorld_App’ with the AWS CodeDeploy:

Before the deployment, the service role ARN (IAM role that authorises service permission to act on behalf of the user) should be defined followed by the deployment group. After that “create-deployment-group” command should be called to create the deployment group by the name of “HelloWorld_DepGroup” that is associated with the application by the name of “HelloWorld_App”

After completing the discussed steps, the monitoring along with the troubleshooting of the deployment is done. Followed by the deployment step, an update is made to the site and redeployment of the site is done to make the changes visible to the Amazon-EC2 instance.

The following section discusses the steps involved in deploying the “Hello World” application using the IBM BlueMix PaaS cloud services. The screenshots/photos of the coding and the steps have been attached with the instructions that are gathered from the official website of the considered PaaS service provider (Schaefer and Hawk 2018).

Developing a toolchain for the new application:

The deemed step has following sub-steps which needs to be followed to complete the objective of the step.

1. Logging in to the IBM Cloud.
2. Navigation to the “DevOps” dashboard.
3. Click on “Create a toolchain” option.
4. Selection of the “Develop a Cloud Foundry app” toolchain option.

Developing a simple webpage:

   The discussed step takes in consideration of the coding part. The following steps are of assistance in achieving the objective.

1. Click the “Eclipse Orion Web IDE” on the toolchain overview page. Accessing the option will automatically create gifignore and .cfignore.
2. The next step would be to select “File>New>File”.
3. A file will be highlighted to enter the file name where “index.html” will be entered.
4. The code shown below need to be entered in the editor area. 

In the deemed step a file named “manifest” is developed that directs the IBM Cloud on the process of deployment of the application. The deployment of the application is possible without the manifest file, however, it is equipped to simplify the deployment process. The process of creating the manifest is listed as follows:

1. “File>New>File” must be selected in the Web IDE section.
2. The above step will highlight a file which need to be named “manifest.yml”.
3. The above step will highlight an editor area, where the code pasted below should be entered.

The above sections showed various steps from creation of the webpage to the development of the manifest page. In the discussed step the deployment and running of the application is done.

1. The first step is to click the “Deploy” button in the Web IDE section. The successful deployment of the app will display And if, the deployment fails, it will show red dot. In the deemed situation modification needs to be made in the unique names in the launch configuration.

Comparison of Bluemix and AWS

The modification can be made by modifying the changing the name in the coding which is shown in the screenshot below:

The deployment and the development of the process, which is related to the “Hello World” application, is clearly shown in a step by step manner for both the concept of the bluemix and AWS. It is very much evident from the above section  that the level fo difficulty which is seen are majorly associated with the sector of deployment and development relatibg to the deployment and the development of the hello world application. It can be stated that the process is very much easy in the Bluemix than the AWS. This is because the complexity level, which is seen in the concept of the Bluemix, is very much less and can be easily achievable. On the other hand, addition to this it can be noted that the number of steps, which is involved in the deployment and the development, is less than its counterpart which directly reduces the difficulty. However, the service, which is related to the AWS service, offers a more descriptive process of achieving the objective. Though it can be stated that considering the mas it will be suitable to state that the difficulty level in the deemed process is very much low in the bluemix when it is directly compared to the AWS.

Relating to the costing model there are mainly five models which are explained below:

• Per usage monitoring: The concept of paying for user can be a big advantage foe most of the organization as well as the employee. It can be stated as a very simple technique which is directly related to the service level of agreement that directly require 24/7 support.
• Per device monitoring: the concept can be considered as a true and tried model and it is majorly seen that the managed service providers report that the concept, which is seen in the sector of per device monitoring, is used widely. The model gives the provision of paying a flat fee taking into consideration the monitoring aspect relating to specific devices such as mobile device and desktop devices.
• Value based pricing: The concept, which is applied to the value based approach, is that the model provides a coverage of the all the services and does not take into consideration the aspect of the individual components. The concept can be considered to be a very important approach due to the factor that the service providers can be benefit from the concept.
• Tiered pricing: The model provides a basic pricing model, which can be used to select the services which is need by an individual or an organization. There are some problem which is related to the model such as the lowest tier of the model is not considered as the model which can be used and the most top level model cannot be used due to the lack of the features which is related to the model.
• Cloud services and security: More than 30 percent of the managed service providers find the concept very much beneficial due to the factor that the model provides all the necessary features, which are required for achieving the proper benefit from the model. 

The up gradation and the allocation process in the concept of cloud computing can be done with the help of the database. The allocation process can be implemented within the database by the means of calibration prices, which is related to the database which is done manually and is not automatic. This type of process which is manual can be considered to be very  much complex due to the factor that it is time consuming. The time consuming aspect is related to the process due to the factor that every time the database would be running on a different architecture and would be involving time relating to the deployment of the process. The process which is related to the up gradation and allocation can be made fast by means of Greedy particle swarm optimization (GPSO) search algorithm which has been proposed instead of the existing greedy algorithm which prevents the local optimum state process of tapping relating to the search reaching the global optimum. 

Deploying ‘Hello World’ application with AWS

Taking into consideration the two service providers that is bluemix and amazon web service, it can be stated that the concept, which is applied to the Bluemix, can be a better option. This is due to the factor the process implementation is very much easy and it can be used by any user who even does not have any prior knowledge of the technology. On the other hand, it can be stated that the model is an open source model which can be implemented in any architecture very easily and achieve benefit from the concept. The model is considered one of the basic model, which can be implemented quite easily and can be also deployed at school level for the purpose of learning.

The main improvement area, which can be related to the working of the bluemix and amazon web service, are stated below:

Bluemix: The model, which is related to the bluemix, can be considered as one of the most basic model which cannot be implemented at a higher level for the purpose of expert studies and implementation. The model should have the features of implementing more features so that the overall working of the model can be implemented for higher standards.

Amazon web service: The model amazon web service can be one of the models which can be implemented only by the experts in that field due to the factor that the model have working complexity involved into the concept. The concept cannot be dealt with for the beginners who are new into the system. The amazon web service should incorporate some of the features, which are basic so that everyone can involve himself or herself.

Conclusion 

The report can be concluded on a note that the concept of cloud computing is playing vital role in the sphere of life of the common people as well as the business organization. The implementation of the concepts such as bluemix and AWS can be very much beneficial for any organization due to the factor that it would be altering the overall working internally and externally within the organization. In most of the cases, the organization tend to achieve benefit from the concept and overall implementation.
