Virtualization and Cloud Computing Services

Question: Discuss about the Virtualization and Cloud Computing Services. Answer: Cloud Computing and its major benefits Cloud computing is defined as a type of internet based computing that helps in providing shared resources and data to computers and other devices (Zissis Lekkas, 2012). The technology is developed for helping people for accessing data. It helps end users by managing their information and data over the network of cloud computing. Cloud computing applies to various traditional high performance computing and supercomputing. Cloud computing provides various benefits, which include: Self-service provisioning is provided to the end users that spin up computing resources for completing any type of workload (Beloglazov et al., 2012). Cloud computing provides elasticity as companies can scale up whenever required and can scale down while the demands are decreased (Dinh et al., 2013). Granular level is used for measuring the resources of computing. It helps users to pay only those workloads and resources they only use (Zissis Lekkas, 2012). Importance of cloud computing in business operations Cloud computing is used in both medium and large size business operations. Even small enterprises are using cloud computing for their business operations (Rittinghouse Ransome, 2016). The cloud computing processes provides number of facilities to business functions, which includes remote accessing procedure of information and data, management of resources and an administration with the help of VPN. Remote accessing techniques of data and information: The Cloud computing helps in providing remote administration to different data and information that are related with the different operations of the business. It has different tools that are used by some authenticated administrations including both internal and external (Zissis Lekkas, 2012). The information and data are configured in the cloud computing architecture. The services that are provided by cloud computing helps in managing cost services, authentication that is related with security. Resource Management: the cloud computing plays a significant role in allocating the resources for proper remote administration. It helps in ensuring the reliable condition of management that is related with cloud computing (Dinh et al., 2013). Cloud computing provides various strategies that are related with the business operations. The strategies include: Approach of Pre copying is used when any specific data required to be transferred repeatedly for saving time that is required for fetching any particular data repeatedly (Beloglazov et al., 2012). Linear schedule focuses on the quality improvement of cloud computing. An algorithm is used for allocation of resources (Zissis Lekkas, 2012). Administration using VPN: The information and data can be managed using Virtual Private Network. Dual band network of cloud computing is supported by the strong network. The channels if used for transferring important data and information. The information and data that are transferred is in the form of packets (Zissis Lekkas, 2012). The VPN helps in connecting the main branch and the head quarters of remote branches. The most important advantage that is related with the VPN cloud computing is getting surrogate network in case if any of the network is failed. Implication of SaaS for ABC Payroll SaaS is a type of cloud service provider that helps in providing data codes that are fully dependent on the applications of software. ABC Payroll can use Software as a Service for maintaining the databases of the clients (Chou Chiang, 2013). The company ABC Payroll deals with different data that are related with taxes bookkeeping and payrolls. The entered amount of data is very huge. Therefore, Software as a service can be helpful in managing the data of the company. Benefits for ABC Payrolls for migrating to a SaaS provider Many application benefits can be provided by software as a service to ABC payroll. The applications are helpful for the organization in operating their business. The benefits include: Easy adaptation: The software as a service can be adopted in any business operation, as it is accessible from any web Browser SaaS can be adopted very easily in ABC payroll because it has high rate of adoption and very low rate of learning curves (Wu, Buyya, 2012). Integrated operations and scalability: Software as Service supports business operations customization. For connecting with customer relation Management and Enterprise Resource Planning SaaS vendors helps in creating Application program Interface. Reduced time consumption: The business related information can be stored in the network of SaaS by ABC Payroll without wasting much time as SaaS help in reducing the consumption of time (Seethamraju, 2015). Low entry cost: The application of SaaS helps in reducing the cost of maintenance of important data and information. Pay for use: By using Saas, one can predict the cost and administration prediction (Ercolani, 2013). Therefore, it is one of the important advantages for ABC Payroll as it can use of application of SaaS by forming a budget for their expense. Responsibility: The model of SaaS is used by a vendor for timely upgrading and providing proper security. Therefore, the data and information can be stored in the network of SaaS (Chou Chiang, 2013). Challenges for ABC Payrolls for migrating to a SaaS provider The challenges that ABC Payroll faces while migrating to a SaaS provider includes: Security of data: ABC Payroll could face data security issue while applying software a service in the operations of the business. This is very much important for backing up the data that is stored while applying the operations in business of ABC Payroll (Seethamraju, 2015). It is always seen the data that are stored on the network of the cloud computing can be hacked very easily. Therefore, important data and information cannot be saved or stored on the network of SaaS without having proper security measures (Wu Buyya, 2012). Even if personal and private data of an individual is saved then also a contingency planning must be made for backing up the data whenever required. Lack of reliability of the application: SaaS cannot be used when all the different operations of the company are dependent on a application (Chou Chiang, 2013). The application needs to be running and operating all the time. Differentiation between shifting to IaaS and implementing IaaS Shifting to IaaS cloud structure from current system of ABC Payroll Computers, mainframes, minicomputers are the components of non- cloud structures of ABC Payroll. The components of non-cloud structures are owned and used by individual users of the company. The cloud structures include various elements like applications, data, operations and infrastructures. Data is defined as information that is machine possessed, which can be used and represented in a computer (Nguyen Cheriet, 2013). For performing business operations, applications are used as programming software. For performing generic applications and for supporting applications, Platforms are used. Infrastructure comprises of computation, physical storage and communication resources (Gonzales et al., 2015).Hence the existing system of cloud computing can be used in the company ABCC Payroll. Portability of different infrastructural component can be retrieved by using the architecture of virtual applications and hardware. The interface of IaaS can be exposed by using the physical communication interfaces. The main factors that must be required for transferring the non- cloud structure have been described (Liu et al., 2013). It is ensured by data portability that reusability of various applications of programming. Portability of platform is reused in the components of platform for reusing the platforms component over the IaaS cloud systems. Implementation of IaaS in ABC Payroll Many factors are there which must be considered by the ABC Payroll for implementing the cloud structure of IaaS. The service that is provided by IaaS for implementing cloud structures include: The structure of IaaS is elastic in nature and it has strong security nature (Abrishami et al., 2013). The resilient and scalable structure of IaaS would help the company inenabling a wide service that must be effective in terms of cost. The infrastructure as a service helps in forming benefit of economy for the vendors of cloud computing. The architecture of Infrastructure as a service helps in leveraging the recent innovations of the ABC Payroll in the field of virtualization, load balancing and multi tenancy (Nguyen Cheriet, 2013). It is very much useful for providing self-provision to the company. The recent deployment in the fields of managed and private cloud services has enabled ABC Payroll. Security is the most important feature hat is provided by the infrastructure of IaaS. The company can operate its business without having any fear of losing important data and information. The structure of IaaS can be used in boosting both the technical and service deliveries architectures of Infrastructure as a service (Gonzales et al., 2015). The data store on IaaS infrastructure is very much beneficial as they can be accessed very easily from anywhere. IaaS infrastructure the ABC Payroll can create the application of WAT for approaching their operation. This helps in providing proper information and business related operations to the key stakeholders (Abrishami et al., 2013). The implementation of infrastructure, as a service is beneficial for the company as it helps in meeting all the demands of the customers very quickly and easily.
