Moving the IT Infrastructure to the Cloud (original) (raw)

Towards a cloud migration framework

2015

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.

Migration to cloud computing the impact on IT management and security

Cloud computing adoption has had a considerable impact on organisations, particularly Small and Medium Enterprises (SMEs), not only by increasing the efficiency of acquiring IT resources, but also on IT management roles and security. In this paper, we discuss the impact that cloud computing is having on IT management roles by examining redundant and emerging roles. Further, since the emergence of cloud computing, security has been one of the main concerns for cloud users. Therefore, security of cloud computing from user's and security professionals' perspectives is explored and related issues discussed. Finally, issues related to migration to cloud computing, as well as security were explored through interviews of IT managers, security professionals, and cloud technical professionals.

Security Criteria in Deciding on Migration of Systems to the Cloud

Proceedings of the 9th International Workshop on Security in Information Systems, 2012

Cloud computing is setting trend in IT world. As it evolves, providers and clients claim their concern about their pros and cons. Some proposals have been made on the methodologies to assess criteria for benefits and risks of the different cloud models. How these proposals deal with security issues (that most IT executives point out as their top concern)? In this paper we go into the issue of how we can incorporate security requirements to a decision making process for whether to migrate legacy systems to the cloud and how to do it. From systems in control of the firms' data centers to systems working partially, if not totally out of their control.

A Study on Cloud Migration Models and Security Issues in Cloud Migration

Journal of emerging technologies and innovative research, 2019

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...

Cloud migration: A case study of migrating an enterprise it system to iaas

2010 IEEE 3rd …, 2010

This case study illustrates the potential benefits and risks associated with the migration of an IT system in the oil & gas industry from an in-house data center to Amazon EC2 from a broad variety of stakeholder perspectives across the enterprise, thus transcending the typical, yet narrow, financial and technical analysis offered by providers. Our results show that the system infrastructure in the case study would have cost 37% less over 5 years on EC2, and using cloud computing could have potentially eliminated 21% of the support calls for this system. These findings seem significant enough to call for a migration of the system to the cloud but our stakeholder impact analysis revealed that there are significant risks associated with this. Whilst the benefits of using the cloud are attractive, we argue that it is important that enterprise decision-makers consider the overall organizational implications of the changes brought about with cloud computing to avoid implementing local optimizations at the cost of organization-wide performance.

Review of cloud migration strategies and providers – an IaaS migration strategy

2018 UBT International Conference, 2018

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.

Key Issues for the Successful Adoption of Cloud Computing

Procedia Computer Science, 2017

Cloud Computing constitutes an alternative for organizations who do not intend to invest in in-house IT resources. It offers a service model on the premise that the consumer has at its disposal the means for manipulating information, over the internet, according to its current needs. However, outsourcing IT poses various challenges, such as the effective control of IT, attention to an increasing number of threats posed by the Internet ecosystem and concerns regarding the efficient use of resources. Hence, the uncertainties about the migration to Cloud Computing can have a negative impact on the adoption of this technology. In order to better inform the decision process launched by organizations considering the alternative of Cloud Computing, this study presents a list of key issues compiled from literature that could assist IT managers steering the organization towards the path of adopting Cloud Computing solutions efficiently and securely. In addition, to better understand those issues and rank them in terms of importance, interviews were conducted with IT directors of enterprises that use and provide Cloud services, endowing the list of issues with the views of practitioners that successfully experienced the migration to the Cloud environment.

Cloud Computing Deployment and Selection Criteria for Organizations

It has not been a long time since cloud computing was introduced to many organizations and businesses. Over this relatively short period of time, many companies have deployed this new technology for their business and many others are planning to move to cloud computing in the foreseeable future. On the other hand, currently we are witnessing a wide range of issues and concerns around cloud services making companies not confident about moving into the cloud. In this paper, the authors have tried to give an overall image of different aspects of cloud computing by using fifteen different metrics. It includes both the advantages and the disadvantages to give companies and businesses a deep insight into the factors they should consider for identification of their application's suitability for the adoption of cloud computing.

Security Migration Requirements: From Legacy System to Cloud and from Cloud to Cloud

Proceedings of the 2nd International Symposium on Computer, Communication, Control and Automation, 2013

Cloud computing became an emerging technology. The benefits have made a lot of institutions and companies looking to use this technology. The process of migration from legacy systems to cloud computing environments is a complex process. The migration process does not represent the movement of data, applications and service only but also presents the process from the early stages of planning and continue until after the selection and transfer of data to a specific deployment model. Security is the biggest concern to consumers during the migration process, whether immigration initial from legacy systems to the environment of cloud computing or migration between the clouds. This paper presents an overview of the security requirements: before, during and after the migration from legacy systems to cloud computing, as well as security requirements data migration between the clouds.
