Cloud Computing ABC Payrolls

Question: Discuss about the Cloud Computing for ABC Payrolls. Answer: Introduction: ABC is a company that deals with the data entry about Payrollss, tax information and accounting data of different clients such as small business organization, individuals, sole traders, etc. The company needs to implement cloud infrastructure for managing their data and information and accessing them from anywhere. SaaS is a cloud service based on software application (Almorsy, Grundy Ibrahim, 2014). Software as a Service or SaaS would help ABC Payrolls with the standardization of software installation in their business environment. The end user of cloud service has to build a server to install and configure the application. Benefits of Software as a Service in ABC Payrolls Less time utilization for operations- SaaS provides the benefit of time saving in business operations for ABC Payrolls. It is a traditional model of cloud computing (Gibson et al., 2012). Hence, the software or application for cloud services is already been configured and installed for use. The users of ABC Payrolls would get the advantage of server provision as they can get the application ready in just few hours and instances. It reduces the time wasted for configuration and installation of the software. The issues that hinder the software deployment process can be reduced by using SaaS cloud service like delay in configuration and lack of necessary software. Lower Costs- SaaS has a lower cost of utilization and application and it can help ABC Payrolls for cost estimating (Almorsy, Grundy Ibrahim, 2014). The cloud service usually resides in a shared multiple environments for SaaS of ABC Payrolls. The cost of getting license for software and hardware of cloud network is nominal in compared to the traditional model of data storage. The overall maintenance cost can be very low for applying cloud services in ABC Payrolls (Zhang et al., 2014). The environment is owned by the SaaS provider and they can share is with customers using services of the cloud provider. Ease of usage- SaaS offers an easy and complete solution to data storage for ABC. The users of ABC Payrolls can easily complete the conceptual proofs and test the functionality of the software provided by SaaS cloud service (Gibson et al., 2012). It would take one instance for ABC Payrolls for smoothly migrating to different versions and upgrading the services. The SaaS can be beneficial for application for large business operations and environment of ABC Payrolls. SaaS even offers a testing the software before purchasing it. It would help users of ABC Payrolls for using the software and getting accustomed to their applications before buying it. Challenges of SaaS implementation in ABC Payrolls SaaS implementation in ABC Payrolls has main limitation of security constraints. ABC Payrolls wants a seamless integration in between SaaS cloud service and their non cloud premise applications for their business operations. The security issues are the main reasons that have prevented the use of SaaS cloud services. Some of the security flaws of SaaS cloud service that ABC Payrolls could face are, Immature identification of management- ABC Payrolls should understand that SaaS cloud service providers do not take care about the integration of their platform for identity services (Zissis Lekkas, 2012). The enterprise firewall consists of identity services that could prevent any external interference to the cloud service. However there are some third party technologies that could get into the cloud structure. Weak Standards of cloud structure- SaaS uses SAS 70 auditing design that would show the vendors about the security measures and data controls (Kshetri, 2013). However, the design is not perfect and there are some issues with the design. Hence, ABC Payrolls could face problems in data storage over SaaS cloud network. Differentiating between migration and implementation of IaaS cloud service in ABC Payrolls Figure 2: Factors affecting IaaS cloud migration and implementation (Source: Lian, Yen Wang, 2014, pp-35) The differences between the migration of current infrastructure to IaaS and implementation of IaaS are, Factors Migration to IaaS Cloud from on-premise system Implementing IaaS from start Cost Less cost as most of the devices can be used Cost is more as all the equipment have to be bought from the beginning Complexity More complex as both the non cloud and cloud equipments have to be managed and operated Less complex when compared to migration as only cloud equipments have to be managed and operated Performance Performance is very good as data and information are stored by using both traditional and cloud techniques (Lian, Yen Wang, 2014) Performance lags as the business operations are completely dependent on cloud services Reliability The method is very reliable as both traditional and cloud method is used for operations Less reliable due to lack of security and presence of some flaws in structure (Zissis Lekkas, 2012) Scale Scaling factor is low as the traditionally stored data is migrated to cloud network Scaling factor is as high as the capacity of the cloud environment (Ghosh et al., 2014) Supporting Application Number of supporting applications both cloud structure (for Data, Applications, platform for operations, and infrastructure) and non cloud (computers, mainframes, minicomputers, and mobile devices) Only cloud supporting applications as the structure supported is Data, Applications, platform for operations, and infrastructure (Da Cunha Rodrigues et al., 2016) Ability to meet future demands Since, the migration involves modifying current on premise structure to cloud structure. Hence, the new system could modify in future also for meeting the needs and demands in future Upgrades and updates are useful for getting newer and latest techniques for operations and applications (Kshetri, 2013). However, the structure would not be able to meet demand that is not related with cloud services. Others It would help in retaining the employees of trust and providing them work satisfaction. The employees knowing how to operate non cloud techniques could be benefitted by this method All the employees who do not know how to operate cloud services would have to be terminated. Hence it would cause growth of hatred and ill feelings towards the system. Table 1: Comparison of various factors for differentiating Implementation and Migration to IaaS (Source: Created by the author) Introduce IaaS in ABC Payrolls The migration of ongoing premise infrastructure to IaaS cloud services would be the best way for introducing IaaS in ABC Payrolls. Migration of IaaS is cost effective, reliable, support various applications and meets the changes in the future demands (Zhang et al., 2014). Hence, ABC Payrolls can migrate to IaaS cloud service easily without exhausting much of resources. It would also help in managing the working ethics and social responsibility of the company. ABC Payrolls can provide some training to the current employees for making them aware of the process of the using cloud services. Therefore the loyal and trustworthy employees would be retained by ABC Payrolls. References Almorsy, M., Grundy, J., Ibrahim, A. S. (2014).
