In-Depth Information
Having multiple partners collaborating for a community cloud infrastructure can help
in terms of the issues and tasks being divided among partner institutions. Also, this helps
in spreading the costs. However, the lack of managerial clarity due to a partnership-based
approach can reduce productivity, especially when an issue occurs. Moreover, the lack of
boundaries defining the managerial domains for the infrastructure on a per-partner basis
can affect managerial communication. Last, in the event of an equipment failure, such as
the failure of a node or a transceiver, the institute responsible might not be able to fix or
replace the affected equipment. This can be attributed to various influencing factors within
an institution, including funds, authority, and permission.
Public Cloud Strategies
Public cloud environments are managed by service providers such as Amazon and Microsoft
and include servers, storage, networking, and data center maintenance operations. Mainly,
there are three basic cloud service management categories for the users to select:
User Self-Provisioning
Cloud services are purchased directly from the service provider,
and payment is based on a per-transaction model.
Advance Provisioning
Customers purchase a set amount of resources and pay a flat fee.
Dynamic Provisioning
This is the most popular model. Customers pay on a pay-per-use
basis. The provider is responsible for allocating resources when the customer requests them
and decommissions them when the user no longer needs them.
Hybrid Cloud Strategies
Hybrid cloud environments, including compute, storage and networking resources, have to be
managed across multiple domains. They consist of an internal private cloud and contracted
services of one or more public cloud providers. A management strategy should define what
needs to be managed, where and how. Over time, the combination of domains might evolve,
but the management strategy should remain consistent.
A sound management policy should address a few key issues:
Installation and configuration policies should specify rules for creating, deploying,
upgrading, and destroying virtualized resources.
■
Access control policies should specify rights and privileges for private/sensitive data
and restricted applications.
■
Billing and reporting policies should specify how users receive usage and cost informa-
tion and stipulate any budgetary controls to prevent unmonitored overrun.
