Hardware as a service - enabling dynamic, user-level bare metal provisioning of pools of data center resources.

We describe a “Hardware as a Service (HaaS)” tool for isolating pools of compute, storage and networking resources. The goal of HaaS is to enable dynamic and flexible, user-level provisioning of pools of resources at the so-called “bare-metal” layer. It allows experimental or untrusted services to co-exist alongside trusted services. By functioning only as a resource isolation system, users are free to choose between different system scheduling and provisioning systems and to manage isolated resources as they see fit. We describe key HaaS use cases and features. We show how HaaS can provide a valuable, and somehwat overlooked, layer in the software architecture of modern data center management. Documentation and source code for HaaS software are available at: https://github.com/CCI-MOC/haasPartial support for this work was provided by the MassTech Collaborative Research Matching Grant Program, National Science Foundation award #1347525 and several commercial partners of the Mass Open Cloud who may be found at http://www.massopencloud.org.http://www.ieee-hpec.org/2014/CD/index_htm_files/FinalPapers/116.pd

Recursive Hardware-as-a-Service (rHaaS) and Fast Provisioning

Hardware as a Service (HaaS) is a new service being developed by the Massachusetts Open Cloud (MOC) to allow physical servers to be allocated to clients in the same way that virtual servers are in existing IaaS clouds. This poster describes the new recursive HaaS project and the fast provisioning customization we are developing. Recursive HaaS allows a HaaS service to be layered on top of an existing one. It will allow testing of new features at performance and scale without affecting the production service. It will also allow clients to host their own HaaS on top of a base HaaS to provide, potentially customized, services to their users. An example customization we are developing is a fast provisioning service that can be used between tenants that have some degree of trust in each other. It will allow nodes to be moved between customers (and a service installed) in seconds, rather than the minutes required by base HaaS
