Chou, D. C. (2015). Cloud computing: A value creation model. Computer Standards & Interfaces, 38, 72-77.

As technology is advancing with such a rapid pace, so is the need for storing the vast and enormous size of data that is probably the most important aspect of cloud architecture. There are many benefits of cloud architecture in networking Industry that should be known before proceeding to our related topic. Cloud architecture first and foremost was initiated by companies such as Cisco to store a vast amount of data in networking that could either be computed or just kept there for future references. Later as the need evolved, this architecture was used to enhance the prospect of networking with a wide array for its usage being recognized simultaneously. The economic aspect of this architecture was also a reason for the massive rise in its users around the world. It uses a central server to store and transfer the data that is required throughout its network.

As the technology evolved and multiple other cloud concept evolved like the BigData concept along with the IoT(Internet of things) enabled appliances and homes, there were many flaws that were seen in the existing cloud architecture. There was delay registered when the amount of data increased with several performance issues. There was also an issue of time taken to transfer the input and receive an output from these devices which was very crucial in an effective working of any smart or IoT enabled appliances. The above-stated issues needed to be rectified to give way for better performance based technology in cloud architecture. This was where Edge and Fog commuting was born.

Cloud commuting along with Edge commuting used the same technology in terms of their performance i.e both of them are involved with the processing of information and its creation in an intelligent and smart manner. However, the key difference is the place where this intelligence is placed in the respective commuting. Fog Computing places the intelligence in a LAN (Local Area Network) from where the return and processing of data take place. This is very vital to avoid any delay in the data transmission throughout the network. Fog, as well as the Edge technology, is very much important in the time of IoT and smart devices. The most important feature of Fog computing is the fact that it decreases the amount of data that is needed to be sent on the cloud which does also helps in decreasing the internet latency or lag, both of which are responsible for better response time in all the devices that are connected to a network. However, due to a large layer of complexities that is required in the transmission of data in a network, Fog was not fit to be integrated with IoT and smart networking because every individual point of passage of data was a potential failure point in the network.

Fernando, N., Loke, S. W., &Rahayu, W. (2013). Mobile cloud computing: A survey. Future generation computer systems, 29(1), 84-106.

Edge computing is another dimension of cloud computing, where the place of installation of the intelligence along with the processing power of the network( most of which are smart or IoT enabled) is directly either on the device or in the very close proximity of the given data source. This "edge" technology removes the scope of sending the data of the IoT enabled network to the centralized cloud every time. This is a very crucial aspect of all the devices that might be connected to the IoT network because system response time is the most important aspect of all the appliances that are connected with IoT in a smart home network. Edge technology gives its users a cutting-edge response time for all the "sensors" and "actuator" that are involved in any IoT enabled device.

The wiring of all the physical aspect of a device with a control system to provide data through automation by the PACs (programmable automation controller) via an on-board system makes it the best choice for all the IoT appliances that are there in a network. These PACs can collect as well as analyze while processing a large amount of data which does help it to recognize which data should be sent to the centralized cloud architecture and which data needs to be stored locally within the network, thus eliminating any time lag.

In order to make full utilization of the existing technology, it is mandatory for the organization to acquire certain skills. It is wrong to assume that just by having a set of sophisticated technology at the workplace; the organization can earn a good amount profit. This concept is very much true for cloud computing as well. Although the technology is quite promising, it is redundant to state that certain traits and skills are required to run it to its optimizing level.As the data, is not stored in a physical device rather, in cloud computing the data is stored in the cloud, it attracts a lot of unwanted attention from a hacker. Another major drawback of this technology is due to the fact that as the devices have to be connected to the web, an experienced hacker can get hold of a particular device which in turn will allow the hacker to control multiple devices as these are connected to a single network.

Gangwar, H., Date, H., &Ramaswamy, R. (2015). Understanding determinants of cloud computing adoption using an integrated TAM-TOE model. Journal of Enterprise Information Management, 28(1), 107-130.

The paper deals with there are three main components of cloud computing. These factors are elaborated below. SAAS better is known as Software as a Service allows the clients use software applications which are located in a remote location with the help of internet. This term is also labeled as software on demand. The clients can access their required software form any given location due to the fact that the service providers host an application and merge the software with the location of their clients. The main benefit of SAAS is the lowering of cost. The biggest driving factor behind this phenomenal technology is that the service providers charge a very small amount of money. This amount of capital is much lower than that of the capital which was to be invested by an organization prior to this technology. SAAS eliminates capital which was invested in sectors like the price of installation, fees required to maintain the infrastructure, fees of license and many more. Therefore, it saves a lot of money which could be used by the higher management later in the future. Some of the primary examples of this service are Google Application, Yahoo Mail, and other web-based email application.

PAAS is the acronym for Platform as a Service. PAAS helps their clients with the ability to develop and publish various applications which can be customized according to the requirements of the clients themselves. Like SAAS, this service is provided to the clients by their service provides via the internet. PAAS is generally used to represent a new model for software development. Due to this factor, PAAS is gaining a huge popularity among its user. The best example to describe PAAS can be Salesforce.com. PAAS provides a flexible framework which speeds up the process of developing software. It also allows speeding up the process of testing maintaining and even deployment of the software to their final clients. Similar to that of SAAS, PAAS also helps to reduce the overall investment in a technical organization. As the platform provided by PAAS, is very much cost effective and provides a good platform to maintain the systems, the overall process of developing new software becomes extremely easy by the higher management of the company.

IAAS or Infrastructure as a Service allows the clients to access IT hardware and resources required for the business on a basis of pay as you go. IAAS is sometimes referred as Hardware as Service. IBM, Google, Amazon are some of the key examples of IAAS. IAAS uses the method of virtualization in order to create and maintain infrastructure and hardware which are stored in the "cloud". This is a big advantage for some of smaller IT firms which lack capital funding in the prior days of the company. IAAS allows the company to grow their IT infrastructure slowly but in a systematic manner. This significantly reduces the overall budget for the small or medium-sized infantry.

Hashizume, K., Rosado, D. G., Fernández-Medina, E., & Fernandez, E. B. (2013). An analysis of security issues for cloud computing. Journal of Internet Services and Applications, 4(1), 5.

Cloud technology has reached a height of popularity among all the IT organization in the world. However, the biggest consumers of this technology remain the small and medium-sized IT firms. Today, cloud computing has become almost a regular part of some of the major IT organizations. The unique features of this technology have helped a number of smaller organizations to set up their infrastructure that too within a very limited financial backup. Also, the security offered by cloud providers has helped to reduce the security problems in all of the IT firms. The paper intends to highlight the features of cloud computing and the role it plays in an IT organization. Although the primary objective of the assignment to discuss the pros and cons of this technology.

As the project highlight the concept of cloud computing in a broad fashion, it will allow the reader to assess all the possible solution in order to mitigate the problem associated with this technology. Another major scope of this project will be to extend the given advantages of cloud computing in order to make it more effective in the near future.

The concept of cloud computing consists of three main types of computer service. The providers may charge a monthly or an annual price to their customers for their service. The providers of these technologies serve their clients via software, platform, and the infrastructure as per the demand from their clients. The clients who wish to opt for cloud computing gets a number of benefits from the technologies which will be later discussed in this assignment.Unlike the formal days when an individual wished to start their own software company, had to pay a large amount of revenue in order to complete their infrastructure, is now, in fact, a matter of distinct past. Today, a lot of entrepreneurs have greatly reduced their investment just by installing cloud computing system.Using this technology provides a great help to the organization to gather a large number of technical resources for future use. However, the biggest benefit of cloud computing is that is to grant any small or medium-sized organization competes even in the global market with limited financial resources. The client, who goes for cloud computing, gets their services delivered to them via "cloud" which makes the organization more flexible and mobile which in the long run will yield a greater profit.

Cloud computing is defined as the procedure to deliver various IT services which are generally retrieved from the internet. In the process of delivering these IT resources to their clients, they do not have to establish a connection with the server. In cloud computing, the data or the service does not have to be stored in a physical device; rather it is stored in a remote database. As long as the client has the ability to access the internet, they can get all the data and the service required for their business. This technology is termed as cloud computing due to the fact that all the resource or the data is stored in a "cloud" and is not located physically and the client can use it according to their wish without being physically present at the location. This facility impacts greatly on the flexibility of an organization.

Overview of cloud based enterprise system and cloud based enterprise systems

Cloud based enterprise system is one of the most used technologies at present days. Using the services with the explanations of predefined service is discussed in the report. However, an organization needs to reap completed advantages from cloud servers, as well as organizational changes. Moreover, the study deals with different types of cloud architecture and selection of architecture suitable for the organizations. Implementing of hybrid cloud approach is discussed in the report along with the steps for migrating to Amazon AWS service.

A cloud based enterprise system can be understood as a remotely located data reservoir that are mostly used to store and retrieve data packets of a network. Cloud based enterprise system serves as the storehouse of large amount of data of various decentralised resources of Information and Technology sector (Gangwar, Date &Ramaswamy, 2015). This was the case in its initial years, which has now changed as a whole new industry in itself. With the evolution and usage of Big Data, cloud based enterprise system's scope have further been increased.

Cloud based enterprise system is considered as the best alternative to share large amount of data as a pool of information which can be accessed by any number of individual system that needs it. This enables the system aligned with the cloud based enterprise system for greater utility. It has greatly impacted the cost benefit ratio of this data sharing sector which has played a vital role in its transformation from its setup from a capital-intensive to a more tangible priced market in the system.Theadvantages of using cloud based enterprise system are described as followed.

• Shared infrastructure: Through the use of model of virtualized software which along with allowing physical services and other network capabilities also helps in data storage. This also facilitates uses in a number of ways including data retrieval and storage and other networking functions.
• Dynamic provisioning: The services can be facilitated through the demands and functions that are need in present scenarios. These are made possible in a cloud through automation software. These automation can help the cloud services to be expanded and contracted as feasible by its users. This automation also checks and recommends on its reliability as well as various other security aspect.
• Managed Metering: This feature allows it to efficiently manage and at the same time optimize various functions such as billing and reporting (Gangwar, Date &Ramaswamy, 2015). This greatly helps its users during the actual billing time with less chances of an error.
• Network Access: Network accessibility is very important aspect of any computing to efficiently and without any system lag, the user can access the cloud from mobile as well as PCs along with other stationary devices using the concept of APIs. Otherthan the stated, it should also be seen that the cloud does works on the latest technology that are utilised in smartphones.

Software as a Service (SaaS)

It is important to have proper reasons for using abstracted resource model. In order to provide overview of the advantages of cloud, it is difficult to have innovations, which is relentlessly pushing the particular boundaries of underlying technology as well as architecture. The virtual machines are generally created with the size needed for diskless servers with storage centralized on SAN. On the other hand, there is fixed and variable size examples are relied on it. The process depends on the architecture and has higher value for having premium hardware as well as software licenses. Moreover, the service is guaranteed with instances and stating the information kept for centralized SAN. The scales instances and resizing of the existing ones can be included in the cases and allows the instances to move new hardware in the case of failure.

Services that are on demand are offered in complete application for its customers. There are also many other scope of SaaS such as enterprise planning for resources, customer management and relationship, along with service management and human resource. The two different types of the SaaS feature being the vertical and the horizontal SaaS. The Vertical SaaS handles all the requirement of a particular sector such as agriculture, finance and healthcare, while, Horizontal SaaS focuses on the developer tools along with marketing and sales.

Platform as a Service (PaaS)

It is a well formed system and very efficient implementation environment that are integrated in cloud based enterprise system along with all its resources, which assist in the an effective utilisation of various products that might range from a simple cloud app to more sophisticated programs that are enabled through different enterprise applications. Therefore, it is necessary to purchase the different resources that are required through the pay as you go model of cloud based enterprise system (Gangwar, Date &Ramaswamy, 2015). They can also be made accessible through various secured internet providers. PaaS does consist many infrastructure like that of the storage, networking and various servers that are in the process of its execution. However, there is difference in the infrastructure of middleware that consist of mainly development tools, intelligence services for the business along with DBMS (database management system). PaaS can also be utilised to manage various web based app for its developing, deploying, and updating the system.

Infrastructure as a Service (IaaS)

The basic concept behind IaaS is that it could be managed over the Internet thus making it an instant computing technology. This provide the users an option to use a server without having to spend a lot of capital for establishing an own private server (Gangwar, Date &Ramaswamy, 2015). As long there is a requirement of certain resources in the IaaS, it could be rented out among the various features that are provided by the infrastructure of IaaS. The individual service providers that the cloud actually controls these specification which are bought at the specific time of the purchase, configuring and installing the software in the OS.

There are various services on this that could be run in clouds along with multiple users, which actually minimizes any upfront investment on its various servers and for the licensing of the software. As software that are integrated through cloud has to be licensed which could be based on the subscription model and are hosted centrally in a server. SaaS is therefore known as software that are on-demand. Previously, it was used to be known as a software and services which was given by Microsoft. All the user that uses thin client can access it through web browsers. All the services in a cloud includes massaging software, office software, payroll software for processing.There are any business scenarios that are apt for the usage of IaaS like followed.

Test and development: The IaaS immensely help the developer for ease of setting up and using various environment according to the specific need of the project. These can also be dismantled very easily when the need demands.

Website hosting: IaaS is the best alternative available for any website for hosting there site in the web. They are far more customizable than the traditional ones (Gangwar, Date &Ramaswamy, 2015).

Web applications: The IaaS also assist various web application by providing them with the best available infrastructure for better optimization of the platform. The most useful of them is the storage along with servers that are application based. This enables the enterprise to quickly deploy various web apps through IaaS.

High performance computing: The performance factor of IaaS is the main reason of its success and wide scale usability among the users (Gangwar, Date &Ramaswamy, 2015). Various other variables can be employed to solve complex problems too, from simulating protein folding to earthquakes.

Big data analysis: The innovative application of big data can also be implemented with the help of IaaS. This in itself is a boon for many service providers and the users.

Benefits and issues of the architecture

There are several advantages along with limitation of adopted cloud architecture in SoftArc Engineering that can be explained as followed.

Cost: There is no monthly review of using the system and no requirements to the refractor of computing resources after completion of the project. In addition, cost of the cappuccino in a day and accessing own dedicated server is one of the major procedures involved with it (Oliveira, Thomas &Espadanal, 2014). Choice is an advantage that shows that there are no boundaries, and limited by the OPEX budget. Hence, it is important to select effective and suitable software service for the organization. The software service models are as followed.

• Software as a service (SaaS)
• Infrastructure as a service (IaaS)
• Platform as a service (PaaS)
• Business Process as a service (BPaaS)

Risks in cloud hybrid strategy

Hybrid IT infrastructure is becoming as the biggest trends of present decade and the strategy can include deployments of the hybrid cloud (Hashem et al. 2015). As per the RightScale 2015 and the State of the Cloud Report, there are 82 percent of the surveyed organizations were running with hybrid cloud strategy as well as Data Center Knowledge stated for adoption of the technologies expected to triple by 2018 (Chou, 2015). The advantages of embracing the hybrid cloud are quite clear. The companies capable to enhance the IT flexibility as well as select solutions fit for specific requirements. Maximizing cost efficiency along with the asset use need to be achieved according to FierceCIO contributor in SoftArc Engineering.

The risks can be listed as followed.

Loss of control: The job of CIO in SoftArc Engineering is managing risk within the organization. There are many views that has total control over the each part of technology strategy of SoftArc Engineering is essential. On the other hand, cloud-based tools are used to the software along with the application changes that occurs on side of the provider. The meaning of IT executive is involved in the process (Son et al. 2014). Hence, according to the contributor there is one of the most vital risks of hybrid cloud based enterprise system.

Compliance: It is one of the issues that are aforementioned for making security challenge. The Businesses of SoftArc Engineering needs to ensure that the parts of cloud strategy are compliant with regulations of the industry. There are several security challenges for the organizations need to deploy hybrid cloud strategies, according to SoftArc Engineering (Hashizume et al. 2013). It includes risk management and security management as well as poorly constructed of the service-level agreements.

Recommendations for Security steps and controls

It is important to provide recommendation for securing the control for the organization. Adopting the effective and suitable method and following the protocols would be helpful for the organization. Having specific versions of Windows XP that have a built-in remote administration package is called as Remote Desktop Connection. Hence, a free cross-platform alternative offers same type of functionality (Modi et al. 2013). In addition, maximization as well as increased of the market share and achieve the objective have various challenges for dynamic nature of organization. Adoption goes up to the companies that look into implementing the hybrid strategies within IT departments that has number of issues (Fernando,Loke, &Rahayu, 2013). These are arising to deal with new technologies, which has hybrid cloud brings.

The technology of the cloud based enterprise system offer us many advantage over the traditional system of computing that was used before. The cloud services can be the major booster for any IT based startup because of the cost effectiveness that the cloud provide along with accessibility. This help any startup to come up with an idea and immediately start on it without having to worry about the economical aspect of the project. Out only the startups,

In today's world, most of Internet using population knowingly or unknowingly uses certain cloud based application.

The various benefit of the cloud based enterprise system are:

• Cost savings: One of the most important benefit of the cloud based enterprise system is the economical aspect of it (Oliveira, Thomas &Espadanal, 2014). It does not demand a lot of capital as oppose to the traditional computing services that require a lot of capital to be invested before it could be used by the clients.
• Security: It assist the system to be more secure and safe and does not compromises with the data of the user that have been stored in the network. The possibility of hack is reducing as the standard of encryption and security features are beefing up in the cloud based system throughout the world.
• Flexibility: The scalability and the flexibility is also far better than the traditional system of the computing services. There is a very limited scope of diving the various responsibility in the traditional computing whereas in cloud, the responsibility are shared between any resources according to the need of the system. Web hosting also enjoys a lot using various cloud platform because of its flexible nature.
• Mobility: As said earlier, there is only a requirement of having an ISP (internet service provider) to access various cloud services through any devices such as phones, tablets and PCs. Smartphone are the new access point of cloud based services globally which can also be used to access Google drive as well as Google apps along with other cloud services.

Remote server administration, resource management and SLA management

It is important to identify the requirements required for remote server administration, resource management as well as SLA management.

Internet connection: An Internet connection with TCP/IP or on the Local Area Network that can be remotely administered required for remote server administration (Garrison, Wakefield & Kim, 2015). Moreover, for the non-malicious administration and user need to install server software on the host system in SoftArc Engineering in order to be viewed by the users.

Connecting: Connecting with the host computer in a window that showing the Desktop of the host appearing needs to have proper control. The client may control the host as the major requirements for the process.

Cloud environment: The SaaS provider uses the shared infrastructure as well as several types of the organization involve with the process. A possibility of loss of the existing customers as well as potential for new customers is required for the process.

Step 1: Downloading the SQLAzureMW Tool: It is required to extract the SQLAzureMW.exe file for the service. Using SQL Server Management Studio to connect local SQL server as well as Amazon Web Service RDS instance would be helpful to complete the process.

Step 2: Beginning with the Migration: It is required to double click on the SQLAzureMW.exe file (Ga & Steenkamp, 2014). The page appearing on the screen as well as requirements to select the Database as an option under analysis is second step.

Step 3: Sourcing the Database Tasks: Entering the Source of details of SQL Server Database connection as well as click on the Connect button is the next step.

Step 4: Creating Scripts: Creating the scripts for selected SQL server objects are required for the process.

Step 5: Destination Database Process: It is required to create a script of the database. Entering into the RDS SQL Server connection credentials as well as connection is the next step.

Step 6: Selection of the Target Database: Selecting the target database that likes to migrate. Creating of database earlier and after that creation of new Database option is involved with the process.

Step 7: The Grand Finale: Verification of SQL Server Management Studio as well as checking of all migrated date is the final step.

Part C: Findings

Cloud based enterprise system does also help medium and small enterprises to run with the minimal level of capital and used premium quality of storage and accessibility to compete with the large firms. On the other hand, the large companies faces a problem of complex data storage and various other performance issues which is their because of very high traffic on their respective websites. This can also be resolved by efficiently implementing the cloud services.to access all its feature and files. Selvamani and Rao (2015) has written that many multinational companies are entering the sector of cloud, some of them for their personal usage while other for different clients, one of those being Google, which has a specific private cloud setup for the effective working of their Google Docs initiative and its services. Other than Google, Microsoft too has its own cloud services where it offer clients o store contents and various other utility.

The capabilities and inventories of IT and the reusability of its data are the most fundamental principle and idea behind cloud based enterprise system. There is also a need to broaden the boundary between the traditional grid computing, autonomic computing, distributed computing and utility computing with that of cloud based enterprise system to achieve more sustainable development (Selvamani& Rao, 2015). Due to many advantages of cloud based enterprise system, there is a wide deal of necessary attention that is there for this technology from users and publications. Out of the many advantages of cloud over traditional computing is the fact that cloud lets you access data from any different part of this world here as in traditional computing, there has to be a local setup where large data storage unit is placed. Cloud thus eliminates this issue of to be physical available near the storage unit.

Conclusion

From the above discussion it can be concluded that the theoretical basis for cloud is found as bins of the resources that comprise compute, storage as well as networking and flexibility in order to allocate amount from each of the bins for creating custom computing environment. It provides the user according to their needs. It is more technically challenging for the users in SoftArc Engineering that offers better performance as well as flexibility that would be helpful for the organization.
