ABSTRACT
The inaugural Editor-in-Cheif (EiC) shares some of the open opportunities and challenges in cloud computing and then introduces the transactions and its progress. Since its launch early this year, IEEE Transactions on Cloud Computing (TCC) has been accepting submission of papers that introduce original and innovative ideas. That means submission of "extended versions" of already published works (e.g., conference/workshop papers) is not encouraged unless they contain significant number of "new and original" ideas/contributions along with more than 49% "brand new" material. TCC has been attracting submissions from academic researchers, industrial practitioners, policy and standards developers, and application communities from all over the world. During the last five months, we have received more than 150 submissions. In addition, four special issues have been scheduled to focus on specific challenges in cloud computing. They are also encouraging submission of revised versions of papers that are recognized as best papers from associated conferences. Along with EB members, I have been managing the content of the transactions and the rigorous peer review process to ensure publication of original and high-quality papers. Based on the quality, focus, and scope of each submitted paper, it either gets assigned to a suitable Associate Editor or desk rejected with suitable suggestions. Each paper that advances to the full review phase is assigned to an appropriate Associate Editor, who seeks three or more review reports from peers and experts in the field and makes an appropriate recommendation. The EiC has been able to make the final decision on each paper based on peer review reports and the recommendation of AE. The IEEE Computer Society is managing the manuscripts workflow from their initial submission to the final publication. The papers accepted for the first issue of TCC cover hot topics in Cloud computing ranging from Cloud security to energy-efficient resource provisioning.
Welcome to the IEEE Transactions on Cloud Computing ( TCC). It is my privilege and honor to serve as the inaugural Editor-in-Chief of TCC. I would like to thank the IEEE and the world-wide Cloud Computing community for giving me the opportunity to serve them.
Let me first share some of the open opportunities and challenges in Cloud Computing and then introduce the transactions and its progress.
1. Opportunities and Challenges
Computing is being transformed to a model consisting of services that are commoditized and delivered in a manner similar to utilities such as water, electricity, gas, and telephony. In such a model, users access services based on their requirements regardless of where the services are hosted. Several computing paradigms have promised to deliver this utility computing vision. Cloud computing is the most recent emerging paradigm promising to turn the vision of “computing utilities” into reality.
Cloud computing started with a risk-free concept: Let someone else take the ownership of setting up of IT infrastructure and let end-users tap into it, paying only for what is been used. A service offering computation resources is frequently referred to as Infrastructure as a Service (IaaS) and the applications as Software as a Service (SaaS). An environment used for construction, deployment, and management of applications is called PaaS (Platform as a Service).




Fig. 1. A bird’s eye view of Cloud computing.
Several IT vendors are promising to offer storage, computation, and application hosting services, and provide coverage on several continents, offering Service-Level Agreements (SLA) backed performance and uptime promises for their services. Cloud computing delivers infrastructure, platform, and software (application) as services, which are made available as subscription-oriented services in a pay-as-you-go model to consumers. The price that CSPs (Cloud Service Providers) charge depends on the quality of service (QoS) expectations of CSCs (Cloud Service Consumers).
Cloud computing fosters elasticity and seamless scalability of IT resources that are offered to end users as a service through the Internet. Cloud computing can help enterprises improve the creation and delivery of IT solutions by providing them with access to services in a cost-effective and flexible manner. A bird’s eye view of Cloud computing is shown in Fig. 1.
Clouds can be classified into three categories, depending on their accessibility restrictions and the deployment model. They are:
Public Cloud,
Private Cloud, and
Hybrid Cloud.
A public Cloud is made available in a pay-as-you-go manner to the general public users irrespective of their origin or affiliation. A private Cloud’s usage is restricted to members, employees, and trusted partners of the organization. A hybrid Cloud enables the use of private and public Cloud in a seamless manner. In a typical public Cloud scenario, a third-party vendor delivers services such as computation, storage, networks, virtualization, and applications to various customers. In a private Cloud environment, internal IT resources are used to serve their internal users and customers. Businesses are adopting public Cloud services to save capital expenditure and operational costs by leveraging Cloud’s elastic scalability and market-oriented costing features. Nevertheless, public Cloud computing also raises concerns about data security, management, data transfer, performance, and level of control.
Cloud computing applications span many domains, including business, technology, government, health care, smart grids, intelligent transportation networks, life sciences, disaster management, automation, data analytics, and consumer and social networks. Various models for the creation, deployment, and delivery of these applications as Cloud services have emerged.
The business potential of Cloud computing is recognized by several market research analysts. My own guesstimate is that the worldwide spending on Cloud services will reach about a trillion dollar by 2020. To achieve this potential, several technological, business, security, and application-oriented challenges need to be addressed.
2. Open Research Challenges
Cloud computing introduces many challenges for system and application developers, engineers, system administrators, and service providers (see Fig. 2). These include:
How do we effectively manage the virtual machine (VM) life cycle to deliver quality expectations of consumers and at the same time reduce the cost delivery of services?
How do we secure the data and computation on the VMs managed by Cloud service providers?
How do we guarantee users’ privacy and trust requirements?
How do we meet legal and regulatory compliance requirements about data hosting in Clouds?
What should the model of pricing for services be?
How do we manage Service Level Agreements (SLAs) and how do we guarantee quality of service (QoS) satisfaction and prevent or minimize SLA violations?
How do we balance the energy consumption and performance of data centers so that users can be charged at a nominal rate?
How do we choose data centers’ locations so that data security, operation costs, and energy consumption meet the terms in the SLA signed with users?
Should the application logic and its scalability be handled by the application itself or be entrusted to a third party service?
What level of replication of data and application components is needed to guarantee reliable delivery of services?
How do we create Cloud applications rapidly and manage their life cycle?
What standards and interfaces are needed for portability and scalability of application services?

3. Introducing the IEEE Transactions on Cloud Computing
The Cloud computing paradigm is rapidly progressing, as evidenced by its adoption for the creation and delivery of innovative applications in several domains including scientific, consumer, social networks, health care, enterprises, banking, government, and big data. Several trade magazines have been actively featuring industrial development in Cloud computing. The IEEE, as part of its “IEEE Cloud Computing Initiative,” has identified the need for a respected journal for publishing research in Cloud computing. To support rapid dissemination of innovative research results (i.e., theoretical and practical models, algorithms, technologies, and solutions for Cloud computing) at a similar pace for the benefit of society, the IEEE launched the new IEEE Transactions on Cloud Computing. The new transactions will publish peer-reviewed articles that provide innovative research ideas and results in all areas relating to Cloud computing. Topics relating to novel theory, algorithms, performance analyses, and applications of techniques relating to all areas of Cloud computing will be considered for the transactions. For more details, please visit the TCC website: http://www.computer.org/tcc
The new transactions is managed by the IEEE Computer Society in partnership with other sister societies, namely, the IEEE Communications Society, the IEEE Systems Council, the IEEE Power & Energy Society, and the IEEE Consumer Electronics Society. The strategic directions of the transactions are managed by the Steering Committee chaired by Professor Jon Rokne.
4. Progress, Process, and Acknowledgements
In my role as the inaugural Editor-in-Chief (EiC) of TCC, one of my first tasks was to establish the Editorial Board (EB) whose members will be responsible for the technical quality of the journal. The members of the EB will serve as Associate Editors and they will be involved in the management of the peer reviews of the submitted manuscripts and selection of reviewers.
In consultation with the Steering Committee of TCC, I have identified leading, internationally recognized, researchers working in Cloud computing from all over the world. On approval from the Steering Committee, the IEEE Computer Society has appointed them as Associate Editors and members of the EB. A complete list of EB members is included at the end of this introduction.
Since its launch early this year, TCC has been accepting submission of papers that introduce original and innovative ideas. That means submission of “extended versions” of already published works (e.g., conference/workshop papers) is not encouraged unless they contain significant number of “new and original” ideas/contributions along with more than 49 percent “brand new” material.
TCC has been attracting submissions from academic researchers, industrial practitioners, policy and standards developers, and application communities from all over the world. During the last five months, we have received more than 150 submissions. In addition, we have scheduled four special issues focused on specific challenges in Cloud computing. They are also encouraging submission of revised versions of papers that are recognized as best papers from associated conferences.
Along with EB members, I have been managing the content of the transactions and the rigorous peer review process to ensure publication of original and high-quality papers. Based on the quality, focus, and scope of each submitted paper, it either gets assigned to a suitable Associate Editor or desk rejected with suitable suggestions.

As the EiC, I have been able to make the final decision on each paper based on peer review reports and the recommendation of AE. The IEEE Computer Society is managing the manuscripts workflow from their initial submission to the final publication.
The papers accepted for the first issue of TCC cover hot topics in Cloud computing ranging from Cloud security to energy-efficient resource provisioning. I hope you will enjoy reading them and get inspired to innovate further.
I would like to thank the authors, reviewers, and readers for their interest in TCC. I acknowledge the strong support offered by all members of the Steering Committee, colleagues from the IEEE Computer Society, members of the Editorial Board, and the Cloud computing community world-wide in getting TCC up and running.
I request your continued support for establishing TCC as the premier forum for Cloud computing research and innovation. Your feedback and comments on further improving TCC are highly appreciated.
