|Distributed Computing Infrastructure Federation Working Group (DCIFED-WG)|
Group Type: Working Group
Group Secretary(s): Andy Edmonds
The purpose of this group is the development and spread-out of a practical set of protocols and formats to interface between different types of Distributed Computing Infrastructures in a secure, SLA-managed manner. We will focus on the federation of such DCIs for two usage scenarios: (1) delegation of workload from one domain into the other, covering job description, submission, and monitoring; and (2) leasing of resources, including resource definition, provisioning, and monitoring. The work of this group will base on existing protocols and standards in order to ensure fast delivery and highest possible synchronization with other groups.
|Group Focus and Scope|
Infrastructure federation is becoming an increasingly important issue for modern Distributed Computing Infrastructures (DCIs): Dynamic elasticity of quasi-static Grid environments, incorporation of special-purpose resources into commoditized Cloud infrastructures, cross-community collaboration for increasingly diverging areas of modern e-Science, and Cloud Bursting pose major challenges on the technical level for many resource and middleware providers. Especially with respect to increasing cost of operating data centers, the intelligent, yet automated and secure sharing of resources is a key factor for success.
The DCI Federation Working Group (DCIfed-WG) will, after initial research, deliver a specification for the automatically negotiated, SLA-secured, dynamically provisioned federation of resources and for Grid- and Cloud-type infrastructures. The scope of the specification will include (1) the delegation of workload from one domain into the other, covering job description,
submission, and monitoring; and (2) leasing of resources, including resource
definition, provisioning, and monitoring.
This group will focus on the creation of a specification for compute-centric federation. This is both necessary and sufficient to allow for interoperable implementations.
DCIfed aims to address the needs of different stakeholders:
* Providers to incorporate dynamic elasticity into their DCI based on current demand;
* Aggregators to provide a simplified view on infrastructure federations;
* Integrators to offer advanced management services beyond the boundaries of current infrastructure types;
* Vendors to use DCI-abstracted data centers in an application-driven, on-demand fashion;
* Users to benefit from otherwise separate infrastructures in a coherent, unified, and transparent way.
The scope will be limited to the high-level federation of DCIs with respect to delegation of workload and leasing of resources. This includes means for describing, negotiating, and agreeing upon the service provided and consumed by the federated systems; the description, submission, and monitoring of workload; the definition, provisioning, and monitoring of resources. Data management details beyond providing endpoints for transfer are excluded; the same holds for network management details beyond the absolute necessities for leasing a resource (i.e. providing a publicly accessible IP).
There are a number of existing standards within OGF which shall serve as basis for the full protocol, interface, and data representation documents for DCIfed:
