Service Architecture and Data Migration †Free Samples to Students

Question: Discuss about the Service Architecture and Data Migration. Answer: Introduction: The cloud has recently become one of the most recent developments that are being embraced by a large number of organizations. These organizations consider migrating their services and operations from the local services to the use of the cloud in order to solve a large number of issues that affect them when they use the local servers. Among others, the issues that occur involve aspects like the integration of their operations, the time it takes to carry out tasks and process and automation of other services when the automation software to use are not in place. The cloud provides a solution to all these issues, through the available software which it provides to its clients and environment of running this software. Organizations are however facing a unique challenge when they are in the processes of leaving their traditional systems and migrating their operations to the cloud. These challenges are brought by the need to ensure that the hosting of the operations takes place effectively and that the organization manages to move the data that it has been using from its local services to the cloud servers. Without this aspect, it becomes very difficult to establish effectiveness on how the operations are carried out. Being among such organizations, Webbs is being faced by a similar problem. The solution to the issue exists in two major options. The organization can decide to utilize an IaaS approach when making the migration to the cloud. Infrastructure as a service (IaaS) model requires the organization to move completely from any form of local operations to the cloud form of operation. It involves taking the complete organizational computing hardware to the cloud. This hardware among others include networks, storage, system management and all servers. When all these aspects are moved from the physical operations to the cloud, the organization ceases to have a need for a well-established data center, cooling, and other hardware aspects that are important to consider. The second option that the organization can take in order to make the migration involves the use of the platform as a service (PaaS) option. In this option, the organization only obtains platforms and databases as a service. The utilization of any of these two options will help the organization manage to move its operations from being locally based to being cloud based. A comparison of the impact that any of these options would have to Webbs organization is therefore appropriate to make before the final decision on the most appropriate option to take is made. Differences between IaaS and PaaS The infrastructure as a service, option of cloud computing help organizations to have infrastructure provided to them. This is infrastructure inform of servers and storage that they may need. This provision is different with when an organization is using a Platform as a Service (PaaS). PaaS is at a higher level since, after the provision of the infrastructure where the organizational operations will be taking place, the providers also provide other environment based and important software services like the operating systems. With this regard, therefore, the first main difference between these two options is the fact that an individual begins establishing his or her system from scratch when using an IaaS, but he or she is provided with environment based software when using a PaaS. The other major difference between these two organizations is the fact that an organization has much more control when using the IaaS service, compared to when he or she is using a PaaS platform. When using an IaaS, an individual is required to select and install his or her own operating systems and any other important software products that are necessary. The individual has a significantly wide capability to control the services compares to when the platform in use is the PaaS platforms. With this regard, therefore, an organization that has a significant value for privacy and discretion of its operations prefers to utilize an IaaS, compared to a PaaS. The other major difference between these two options is the fact that using a PaaS service provides an individual or organization with an opportunity to establish effectiveness, while on the other hand, using an IaaS platform requires an individual to establish that platform. For an IaaS client, the providers are only concerned in providing the infrastructure. With this regard, therefore, any other software needs that might be required to establish a necessary environment are provided by the client. This is however not the case for a PaaS client. For such a client, the providers are fully concerned with ensuring that the environment is ideal for the client to develop, install and utilize software (Stevens, 2017). Advantages and Disadvantages of PaaS and IaaS Platform as a service (PaaS) Advantages The utilization of PaaS for the purposes of running applications and creating them enhance the agility of the user. This aspect makes many users to prefer the utilization of this service. The use of this service help individuals and organizations to focus their resources to specific business matters that are considered very important. The activity of using PaaS as the means of operation helps organizations and individuals to save money. This is because the amount that an individual pays in subscription is not capable of purchasing a machine that is e equally fast. The other advantage is the fact that the utilization of the PaaS Platform allows individuals to obtain and utilize the best technology that exists. Disadvantages Many organizations lack sufficient confidence on the aspects of data security that the PaaS providers give, and thus there is fear of unauthorised access to organizational data, which could cause major problems. The PaaS flexibility is to some extent limited, compared to the flexibility that is provided to clients at the IaaS level. This is because in this level, clients decide many more aspects like operating systems that they will utilize. Since the number of PaaS vendors are limited, providers have a tendency of establishing customer captivity strategies, which limit the choices that customers can make in future. Integrations problems that sometimes occur due to aspects and state of in-house systems and applications. Infrastructure as a Service (IaaS) Advantages This service provides a high level of flexibility and choices for a client, which makes it appropriate for use. A client is able to take advantage of the elasticity of the cloud to reduce pricing and also in some occasions obtain access to a necessary higher computing power. The option does not provide a need for an individual to manage the underlying data centres (Service Architecture, 2017). The IaaS providers provide an individual with the service of making software and platform upgrades. Disadvantages The individual or organization has the responsibility to version and establish all the necessary upgrades. The security features of the servers stored in the cloud may lack a sufficient provisions like an individual may want. In some countries, legal reasons may prohibit the aspects of migrating data centres to cloud servers that are located in other geographical regions. From the information that is provided in this analysis and consideration of the situation that the organization is currently in, I would recommend the utilization of the PaaS service for the migration to the cloud, compared to the IaaS. I would recommend this service over the others because it has the capability of providing the organization with an opportunity to make developments of strategies and software with the utilization of the platform for development and running them. This aspect is beneficial for the organization since less time and resources will be spend in carrying out the activities that are considered less important. References Service Architecture, (2017).
