Migration Management in Cloud Computing

2018

Cloud computing is a dynamic paradigm that is influencing activities in virtually all facets of the IT world. It has become quite easy to deploy applications on the cloud. Storage is also available based on user’s needs and can be scaled up or down as required by the user. Computing resources have also been made available on virtual machines. Furthermore, applications are available to users supplied by cloud providers. The activities on the cloud has made migration to the cloud desirable to most organizations and enterprises. Adopting the cloud is expected to reduce cost and the need for investment in computing infrastructure. However, most organizations are still concerned about the likely challenges of migrating to the cloud. The goal of this paper is to provide an insight into cloud computing with respect to migration issues. The paper discusses cloud computing and the benefits of migration. It also examines the challenges of migration. Furthermore, present issues of migration as...

Cloud computing rules in the new digital transformation world and gets wide acceptance in the field of business. The cloud can solve many problems like scalability of the business, flexibility of the business, cost and performance that may come across while running an enterprise. In fact, by digital transformation, fixed costs may get reduced, a more flexible allocation of resources is possible, faster development of the enterprise is resulted, worldwide reach is through the cloud highly appreciable, a safer change control process, and faster time-to-market with objectively better products. Even though it promises many benefits, it is not an easy task to migrate to cloud platform from a current conventional business platform. Cloud migration introduces its own issues. While looking for migrating business from on-premises to cloud, many challenges should be kept in mind for successful migration.

This paper presents a novel framework for organisations to carry out a structured feasibility study on Cloud migration and to decide Cloud Migration Strategy. Following the framework helps an organisation to decide whether Cloud migration is a feasible option for them, and if so, the best strategic approach towards Cloud migration. It is a crucial and sensitive part for any organisation to decide whether they should move to Cloud Computing platform. The decision requires strategic approach with proper feasibility study. Several technological, human, security and financial factors are involved in decision making process to move to the Cloud. The proposed framework helps an organisation to carry out a feasibility study to decide whether to move to the Cloud, and if so, what would be the best approach towards Cloud migration. The proposed framework addresses the factors that an organisation must explore to decide on Cloud migration. Cloud Computing has its own pros and cons. A whimsical decision to move to the Cloud may be disastrous for an organisation. Following the proposed framework will help organisations to carry out a structured and integrated feasibility study deal with the decision on Cloud migration.

Cloud migration is the process of transferring the data, applications, operating systems and all other IT resources to cloud or a physical server. Cloud migration can also defined as migration of organizational infrastructure, computing resources, physical storage, Operating Systems, platform services and software are moved to the cloud. It is often involves combining an on-site IT infrastructure with a hybrid cloud, that may be accessed over the Internet for a nominal fee. This paper is to study and understand Different cloud migration Models and all security concerns to be taken into account when the user wants to go for Cloud Migration. Even though the advantages of usage the cloud seems to be attractive, the enterprise decision-makers should also consider the security threats associated with cloud-service migration, thereafter have to take necessary precautions to overcome or to eliminate those security issues and perform a threat free cloud migration to ensure data confidential...

Companies are addressing the Cloud Computing issue more actively recently, as a part of a move towards a more agile and flexible IT infrastructure since benefitting from an IT infrastructure that is flexible, scalable, high-performance and up-to-date is no longer a luxury or the exception to a rule. The issue they address is "Which is the best strategy?" Of course, this is not a simple issue given that the cloud can impact an organization's application picture across several dimensions. When an organizations made the decision to consider cloud services for its application or infrastructure deployment, it's important to understand the fundamental differences between the core categories of cloud services available since IT leaders and enterprise architects should prepare an overarching cloud strategy. The cloud is a very broad concept covering different types of online services, but when referring to cloud procurement, usually there are three models to be taken into the consideration, such as Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). Another thing that needs to be addressed is choosing the provider of the cloud platform as service. To do that the organization needs to anticipate the storage, apps they use, performances they need, price, flexibility, etc. Through this review study research we're going to present shortly SaaS and PaaS as cloud service models and will describe in more details a possible migration IaaS strategy.

Along with the significant advantages of cloud computing paradigm, the number of enterprises, which expect to move a legacy system towards a cloud, is steadily increasing. Unfortunately, this move is not straightforward. There are many challenges to take up. The applications are often written with the outdated technologies. While some enterprises redevelop applications with a specific Cloud provider in mind, others try to move the legacy systems, either because the organization wants to keep the past investments, or because the legacy systems hold important data. Migrating the legacy systems to the Cloud introduces technical and business challenges. This paper aims to study deeply and to compare existing Cloud migration methods, based on Model Driven Engineering (MDE) approach to highlight the strengths and weaknesses of each one. Finally, we have proposed a Cloud legacy system Migration Method relied on Architecture Driven Modernization (ADM), and explained its working process.

Many enterprise software systems supporting IT services are characterised by a need for a high computing capability and resource consumption (Armbrust et al. 2010; Buyya et al. 2008; Koçak et al. 2013). Cloud Computing initiatives have received a significant attention as a viable solution to address these requirements through offering a wide range of services, which are universally accessible, acquirable and releasable in a dynamic fashion, and payable on the basis of service usage. Hence, organisations view the cloud services as an opportunity to empower their legacy systems.

Research around cloud computing has largely been dedicated to addressing technical aspects associated with utilizing cloud services, surveying critical success factors for the cloud adoption, and opinions about its impact on IT functions. Nevertheless, the aspect of process models for the cloud migration has been slow in pace. Several methodologies have been proposed by both academia and industry for moving legacy applications to the cloud. This paper presents a criteria-based appraisal of such existing methodologies. The results of the analysis highlight the strengths and weaknesses of these methodologies and can be used by cloud service consumers for comparing and selecting the most appropriate ones that fit specific migration scenarios. The paper also suggests research opportunities to improve the status quo.

Moving mission-oriented enterprise applications to cloud environments is a major IT strategic task and requires a systematic approach. The foci of this paper are to review and examine existing cloud migration approaches from the process models perspective. To this aim, an evaluation framework is proposed and used to analyse and compare existing approaches for highlighting their features, similarities, and key differences. The survey distills the state of the art in cloud migration research and makes a rich inventory of important activities, recommendations, techniques, and concerns that are commonly involved in the migration process in one place. This enables academia and practitioners in the cloud computing community to get an overarching view of the cloud migration process. Furthermore, the survey identifies a number challenges that have not been yet addressed by existing approaches, developing opportunities for further research endeavors.
