Cloud management is the management of cloud computing products and services. Public clouds are managed by public cloud service providers, which include the public cloud environment’s servers, storage, networking and data center operations.〔Gens, Frank. (2008-09-23) “Defining ‘Cloud Services’ and ‘Cloud Computing’,” IDC Exchange. ()〕 Users of public cloud services can generally select from three basic categories: * User self-provisioning: Customers purchase cloud services directly from the provider, typically through a web form or console interface. The customer pays on a per-transaction basis. * Advance provisioning: Customers contract in advance a predetermined amount of resources, which are prepared in advance of service. The customer pays a flat fee or a monthly fee. * Dynamic provisioning: The provider allocates resources when the customer needs them, then decommissions them when they are no longer needed. The customer is charged on a pay-per-use basis. Managing a private cloud requires software tools to help create a virtualized pool of compute resources, provide a self-service portal for end users and handle security, resource allocation, tracking and billing.〔Henderson, Tom and Allen, Brendan. (2010-12-20) “Private clouds: Not for the faint of heart”, NetworkWorld. ()〕 Management tools for private clouds tend to be service driven, as opposed to resource driven, because cloud environments are typically highly virtualized and organized in terms of portable workloads.〔Whitehead, Richard. (2010-04-19) “A Guide to Managing Private Clouds,” Industry Perspectives. ()〕 In hybrid cloud environments, compute, network and storage resources must be managed across multiple domains, so a good management strategy should start by defining what needs to be managed, and where and how to do it.〔 Policies to help govern these domains should include configuration and installation of images, access control, and budgeting and reporting.〔 Access control often includes the use of Single sign-on (SSO), in which a user logs in once and gains access to all systems without being prompted to log in again at each of them. ==Aspects of cloud management systems== A cloud management system combines software and technologies in a design for managing cloud environments.〔("Definition: Cloud management", ITBusinessEdge/Webopedia )〕 Software developers have responded to the management challenges of cloud computing with cloud management systems. HP, Novell, Eucalyptus, OpenNebula and Citrix, for example, sell management systems specifically for managing cloud environments.〔 At a minimum, a cloud-management system should have the ability to:〔 * manage a pool of heterogeneous compute-resources * provide access to end users * monitor security * manage resource allocation * manage tracking For composite applications, cloud management systems also encompass frameworks for workflow-mapping and -management.〔An innovative workflow mapping mechanism for Grids in the frame of Quality of Service (Elsevier.com )〕 Enterprises with large-scale cloud implementations may require more robust cloud management tools which include specific characteristics, such as the ability to manage multiple platforms from a single point of reference, or intelligent analytics to automate processes like application lifecycle management. High-end cloud management tools should also have the ability to handle system failures automatically with capabilities such as self-monitoring, an explicit notification mechanism, and include failover and self-healing capabilities. Cisco recently launched its InterCloud solution to provide flexibility to dynamically manage workloads across public and private cloud environments.〔 The concept of a Cloud Management Platform (CMP) has emerged.〔 For example: 〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Cloud management」の詳細全文を読む スポンサード リンク
