Below is the notes for the topics
Cloud-based IT resources need to be set up, configured, maintained, and monitored. The systems covered in this chapter are mechanisms that encompass and enable these types of management tasks. They form key parts of cloud technology architectures by facilitating the control and evolution of the IT resources that form cloud platforms and solutions.
The following management-related mechanisms are described in this chapter:
• Remote Administration System
• Resource Management System
• SLA Management System
• Billing Management System
9.1. Remote Administration System
The remote administration system mechanism (Figure 9.1) provides tools and user-interfaces for external cloud resource administrators to configure and administer cloud-based IT resources.
A remote administration system can establish a portal for access to administration and management features of various underlying systems, including the resource management, SLA management, and billing management systems described in this chapter
The tools and APIs provided by a remote administration system are generally used by the cloud provider to develop and customize online portals that provide cloud consumers with a variety of administrative controls. The following are the two primary types of portals that are created with the remote administration system:
• Usage and Administration Portal – A general purpose portal that centralizes management controls to different cloud-based IT resources and can further provide IT resource usage reports
• Self-Service Portal – This is essentially a shopping portal that allows cloud consumers to search an up-to-date list of cloud services and IT resources that are available from a cloud provider (usually for lease). The cloud consumer submits its chosen items to the cloud provider for provisioning.
Depending on:
• the type of cloud product or cloud delivery model the cloud consumer is leasing or using from the cloud provider,
• the level of access control granted by the cloud provider to the cloud consumer, and
• further depending on which underlying management systems the remote administration system interfaces with, ...tasks that can commonly be performed by cloud consumers via a remote administration console include:
• configuring and setting up cloud services
• provisioning and releasing IT resource for on-demand cloud services
• monitoring cloud service status, usage, and performance
• monitoring QoS and SLA fulfillment
• managing leasing costs and usage fees
• managing user accounts, security credentials, authorization, and access control
• tracking internal and external access to leased services
• planning and assessing IT resource provisioning
• capacity planning While the user-interface provided by the remote administration system will tend to be proprietary to the cloud provider, there is a preference among cloud consumers to work with remote administration systems that offer standardized APIs. This allows a cloud consumer to invest in the creation of its own front-end with the fore-knowledge that it can reuse this console if it decides to move to another cloud provider that supports the same standardized API. Additionally, the cloud consumer would be able to further leverage standardized APIs if it is interested in leasing and centrally administering IT resources from multiple cloud providers and/or IT resources residing in cloud and on-premise environments.
9.4. Billing Management System
The billing management system mechanism is dedicated to the collection and processing of usage data as it pertains to cloud provider accounting and cloud consumer billing. Specifically, the billing management system relies on pay-peruse monitors to gather runtime usage data that is stored in a repository that the system components then draw from for billing, reporting, and invoicing purposes
The billing management system allows for the definition of different pricing policies, as well as custom pricing models on a per cloud consumer and/or per IT resource basis. Pricing models can vary from the traditional pay-per-use models, to flat-rate or pay-per-allocation modes, or combinations thereof. Billing arrangements be based on pre-usage and post-usage payments. The latter type can include pre-defined limits or it can be set up (with the mutual agreement of the cloud consumer) to allow for unlimited usage (and, consequently, no limit on subsequent billing). When limits are established, they are usually in the form of usage quotas. When quotas are exceeded, the billing management system can block further usage requests by cloud consumers.
