Cloud Computing Guidance 


Cloud Computing Market Maturity Cloud Computing Market Maturity

Due to its exponential growth, cloud computing can no longer be considered an emerging technology, but neither is it (yet) a mature and stable technology. This white paper reports the results of a recent study conducted by ISACA and the Cloud Security Alliance (CSA) to examine cloud market maturity through four lenses: cloud use and satisfaction level, expected growth, cloud-adoption drivers, and limitations to cloud adoption. The study determined that the increased rate of cloud adoption is the result of perceived market maturity and the number of available services to implement, integrate and manage cloud services. Business drivers influencing cloud adoption include user satisfaction and cloud-driven innovation, and technology drivers focus on scalability, agility and cost reduction. While small/medium enterprises and large organizations have differing priorities, overall the mean scores are high for expected and realized benefits from cloud usage.

Controls and Assurance in the Cloud: Using COBIT 5Controls and Assurance in the Cloud: Using COBIT 5

This practical guidance was created for enterprises using or considering using cloud computing. It provides a governance and control framework based on COBIT 5 and an audit program using COBIT 5 for Assurance. This information can assist enterprises in assessing the potential value of cloud investments to determine whether the risk is within the acceptable level. In addition, it provides a list of publications and resources that can help determine if cloud computing is the appropriate solution for the data and processes being considered.

Cloud Governance: Questions Boards of Directors Need to AskCloud Governance: Questions Boards of Directors Need to Ask

Cloud computing is gaining momentum. As cloud offerings gain maturity, cloud service providers are becoming more competitive. Some providers are reducing prices as they realize investments and leverage economies of scale. Others are differentiating based on quality, for example, providing better availability, improved security or enhanced ability to manage services. While the benefits of cloud computing are real in economic, strategic and operational terms, realizing those benefits is not a simple process. To achieve the benefits of cloud computing, adoption drivers must be aligned with enterprise goals and objectives, and business and cultural factors must be favorable for adoption. Like any investment, cloud projects should be guided by the board of directors to ensure value creation and minimization of risk. When evaluating cloud initiatives, board members should ask their management teams specific questions, the answers to which will determine whether cloud services will have a positive and sustainable impact on enterprise goals and whether risk remains within enterprise tolerances.

Calculating Cloud ROI: From the Customer Perspective

Marketing hype claims that cloud computing can help any enterprise meet most IT service needs at a lower total cost of ownership (TCO) and higher return on investment (ROI). However, the promise of the cloud requiring minimal capital investment and the subjectivity of some cloud benefits have created some confusion among IT professionals trying to determine the benefits of adopting cloud services. Calculating ROI for cloud services requires some up-front work to understand business requirements, organizational maturity, control considerations and regulatory requirements and to quantify benefits and costs associated with the cloud model that the enterprise has selected. To determine whether the cloud is a viable option, it is necessary to separate the hype from reality.

Security Considerations for Cloud ComputingSecurity Considerations for Cloud Computing

Security Considerations for Cloud Computing presents practical guidance to facilitate the decision process for IT and business professionals concerning the decision to move to the cloud. It helps enable effective analysis and measurement of risk through use of decision trees and checklists outlining the security factors to be considered when evaluating the cloud as a potential solution.

There are five essential characteristics, three types of service models and four major deployment models to be taken into account relative to cloud computing. To ensure a common understanding of these models, this publication describes the characteristics of each characteristic and model.

Guiding Principles for Cloud Computing Adoption and Use

The drive for value, the need to reduce technology costs and the business demand for increased agility in how technology is used have caused enterprises to adopt cloud computing strategies. Cloud represents a fundamental shift in how technology is acquired and managed in enterprises. This shift can result in pressure on the enterprise when its structure, culture, policies and practices, and enterprise architecture have not evolved to address the changes inherent in the cloud computing shift. This paper describes the nature of cloud computing and areas of pressure that, when not addressed, can increase risk to the enterprise. It also presents six principles for cloud computing adoption and use that can guide management toward more effective cloud implementation and use, reduction of pressure points, and mitigation of potential risk.
