Question: Discuss about the Benefits and Challenges of Cloud Services. Answer: Introduction Cloud computing plays a great role in providing various advantages over the Smartphone applications and other technical advancements within the growing market place. This report is elaborating various benefits of cloud computing in this sector. Cloud Computing for Smartphone-like devices apps development and growing in the marketplace Benefits of cloud computing over Smartphone applications Cloud computing provides various benefits to the field of mobile applications of the Smartphone (Chandramouli, Iorga Chokhani, 2014). These applications make the operations and system functionalities easier with respect to the technical advancements as well as with respect to the user demands. Some of these advantages are elaborated in this report. These are explained as follows: Sharing of information: Previously the users needed improvised system architecture that is the hardware and software for sharing data and important information with the help of their mobile devices (El Amraoui Sethom, 2016). In contrast with this fact, in the contemporary times, the users dont need the complex architecture such as complex hardware and software for transferring their data and information. In spite of this, the cloud based smart phone applications made the system made these transfers easy and effective accordingly the contemporary scenario. Enhanced features and functionalities: New cloud applications are easy to operate the within the smart phones in order to maintain the effectiveness of the operations at present situation. In addition to this, enhanced features and functionalities of system provide more effectiveness to the users with respect to their demands and needs in the contemporary timing (Garg, Versteeg Buyya, 2013). The technical feasibility and effective functional options provided through the cloud computing applications in the smart phones enhances the speed of operations as well as this ensures about the accuracy of the results collected from the cloud computing applications. Ease of access: Cloud provide various kinds of access to the users as this provides private, public and protected services to the users. All of these access patterns are easy to be operated by the users (Kovatsch, Lanter Shelby, 2014). This accessing the process is not dependent on the place, time and other aspects related to the users applications. In addition to this, mostly the organization uses the private and protected features. Some cloud hosts provide the public access to their data in order to maintain its features. Broader reach of the users: Cloud features can be used globally that defines the effectiveness of the system architecture of the cloud computing approaches (Park Kim, 2014). In addition to this, there is various other technical feasibility analysis that ensures about the effectiveness of the cloud computing over smart phone applications. Cost effectiveness of the system architecture as well as the vendors: Now a days the cloud vendors are easily available and any organization or institute can utilize the cloud services within selective cost structure within their premises (Rodrguez-Garca et al., 2014). Challenges and benefits of SaaS Greentek is one application development organization that mainly deals with medical research and development aspects. In contrast with this fact, the organization wants to migrate their system architecture to the PaaS system of cloud system (Sunyaev Schneider, 2013). In contrast with this fact, there are various challenges as well as various benefits involved in this migration process. These challenges and benefits are elaborated in this part of the report. These are given as follows: Benefits of PaaS Quick Development and Testing: Greentek can easily cope up with the different configurations and developmental features of the system architecture. In addition to this, the deployment and development team of Greentek can easily operate multiple machines at different locations as per their demands (Willcocks Lacity, 2016). In contrast with this fact the testing and other important development features can be tested with the help of PaaS application within the organization. Dynamic allocation: In accordance with the competitive market places, IT departments need the flexibility and operational excellence for implementing new application within the organization (Zhang, Cherkasova Loo, 2015). Dynamic allocation provides effective testing opportunities and market analysis with the help of cloud application support. Increased focus for business and international entrepreneurship: The organizational heads are responsible for the effective decision makings and other important aspect involved within the system architecture of the Greentek. This aspect allows the organizational heads in solving various issues that helps them to focus on the international requirements of business (Zheng et al., 2013). Challenges of PaaS In contrast with various kinds of benefits of PaaS applications, there are various challenges that are included within the Greentek. These challenges are elaborated as follows: Data security: Like other cloud computing applications, PaaS also involves various technical and data security related issues within the system architecture of Greentek. This aspect reduces the technical feasibility of the system architecture (Chandramouli, Iorga Chokhani, 2014). The third party hosts involves various malicious codes and effective threats within the system architecture of the organization. Limited Flexibility: The PaaS solution cannot match with the IaaS applications or solutions within the organizational structures (El Amraoui Sethom, 2016). The product of PaaS does not match in compatibility with the SaaS products. This aspect also reduces the effectiveness of the system architecture in PaaS applications in Greentek. Customer Captivity: The customer captivity with the help of limited number of PaaS vendors is not enough to serve them better way (Garg, Versteeg Buyya, 2013). This aspect also reduces the effectiveness of the system offerings of the PaaS. Problems of integration: There is various integration issues involved within the system architecture of the PaaS applications. This application can trigger the increase of complexity of the system. Challenges of the SaaS within Greentek Greentek wants to implement the SaaS application in order to improvise their system architecture. In contrast with these facts, there are various challenges of SaaS applications and these are explained as follows: Security and privacy challenges: SaaS is nothing but the application of clod base and it involves various security and privacy threats within the system architecture within the technical domain of Greentek. This aspect is considered as one of the most effective challenges of Greentek. Hybrid IT infrastructure: SaaS is one of the most complex hybrid architecture that offers various complexities within the system architecture of Greentek. Once the organization combines its existing system architecture with the cloud applications then it becomes more complex than the previous one (Kovatsch, Lanter Shelby, 2014). Complex architecture: Complex architecture is another disadvantage of the SaaS applications involved within the system architecture of the Greentek. In addition to this, the complex architecture involved within SaaS cloud set up makes the operations tough to be managed (Park Kim, 2014). Lack of skills among employees: Most of the time, the employee does not have proper skills and effective knowledge about the system architecture of Greentek (Rodrguez-Garca et al., 2014). This aspect reduces the chances of managing the complex system architecture of Greentek. Access challenges: In contrast with various disadvantages of the SaaS, access challenge is another disadvantage of SaaS applications. Whenever any organization or system heads are using the tools of SaaS, access control becomes a difficult challenge for them (Sunyaev Schneider, 2013). Any traditional software offers various monitoring setting to the users in order access the information and data within the cloud. In contrast with this fact, the SaaS applications does not provide this controlling measures to the users in order to maintain the system architecture and various other functions. Time constraint: Time constraint is another technical disadvantage of the SaaS applications within the system architecture (Willcocks, Lacity, 2016). As the complexity of the system architecture is increased due to the SaaS implementation process, time constraint makes the system architecture more inefficient in Greentek. Faulty integration: Faulty integration is another disadvantage of the SaaS application within Greentek. In addition to this, the accounting and sales data are not synced with the system architecture of SaaS application (Zhang, Cherkasova Loo, 2015). This is known as the faulty integration of the SaaS application within any organization. Uploading of files and other aspects that are important to be connected may create issues during the transfer of files and data. Conclusion This report is elaborating all the benefits of the cloud computing in the field of Smartphone applications in the present era. This assignment is considering Greentek, one application development organization that wants to implement SaaS within their organization. In contrast with this fact, various benefits and challenges are being elaborated in this assignment. References Chandramouli, R., Iorga, M., Chokhani, S. (2014).
