Dear ISOD-RG members,
It was agreed at the last meeting to propose an initial drafts of two
documents ISOD use cases and ISOD BCP.
Thanks to Chin, first draft has been posted and discussion is active.
Now I want to propose first ideas about the BCP document. This can also
provide a basis for discussion at the group's meeting on Wednesday.
The draft document is attached and textual version is appended below for
easier commenting and discussion.
Some general issues to discuss:
1) How much we want to describe Network Resource Provisioning Systems
(NRPS) of which many of us knows a lot and also developed?
2) Template for collecting BCP information
3) General structure of the document - NRPS, Cloud IaaS, existing BCP,
standards, Projects, middleware, or we better limit number of topics?
Comments are welcome and hope on fruitful discussion during the meeting.
Regards,
Yuri

On-Demand Infrastructure Services Provisioning Best Practices
Contributors
Goal
The aim of this document is to provide an overview of best practices in
provisioning infrastructure services on-demand that includes both
traditional Network Resources Provisioning Systems (NRPS) and recently
emerged Cloud based infrastructure services provisioning that may
include different components that need to be combined into complex task
or project oriented complex infrastructure comprising of compute,
storage, applications and connecting them network infrastructure.
The proposed document summarises discussion among members of the OGF
ISoD Research Group and aims to facilitate discussion on achieving
interoperability and effective use and development of modern and future
infrastructure services provisioning systems.
1. Introduction
Traditionally area of provisioning services or resources on-demand was
related to provisioning network connectivity or bandwidth on-demand
(BoD). There are many systems proposed for these purposes. The document
provides information about such systems as
The Cloud Computing is developing as a technology for provisioning
infrastructure services. In particular, Cloud Infrastructure as a
Service (IaaS) service model specifically focused on providing
infrastructures comprising of compute, storage and network for solving
user defined tasks and/or supporting user defined processes or
workflows. In general, other Cloud service model such as
Software-as-a-Service (SaaS) or Platform-as-a-Service (PaaS), if used
for supporting customer defined production or collaborative development
processes (or migrating from traditional enterprise owned IT to Cloud
based infrastructure) will also require integration of the provisioned
software or platform components into infrastructures.
The proposed below overview and taxonomy of best practices targets to
provide useful information for developing common and future
infrastructure services provisioning models, architectures and frameworks.
2. Network Resources Provisioning Systems (NRPS)
TODO: Set of characteristics and parameter need to be established to
describe existing NRPS. For example:
Description
Diagram
Parameters
Implementation and examples of use
2.1. OSCARS
2.2. Harmony
2.3. Autobanh
2.4. UCLP
2.5. Other NRPS
- Argon
- Argia
3. General and Cloud Oriented Network Infrastructure Services Provisioning
3.1. GEYSERS Generalised Infrastructure Services Provisioning
3.2. GEANT Virtualised Services (and Composable Services??)
3.3. ORCA-BEN: a lease-based distributed control framework
3.4. HERO (Hybrid Networking Project for Research Oriented Infrastructure)
4. Provisioning infrastructure services in Clouds
The current Cloud services implement 3 basic provisioning models:
Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and
Software as a Service (SaaS). There are many examples of the latter two
models, PaaS and SaaS that are typically built using existing SOA and
Web Services or REST technologies. However, the IaaS model, if intended
to provision user or operator manageable infrastructure services,
requires a new type of the service delivery and operation framework what
is discussed in this paper.
4.1. Amazon Web Services
Business model

5. Existing BCP documents
This section will present short summary of known BCP documents on
infrastructure services
6. Related standards

infrastructure services

6.3. IETF
7. Existing Cloud Middleware for Infrastructure Services Provisioning
7.1. OpenNebula
7.2. OpenStack

8. Projects on Infrastructure Services Provisioning – To be discussed
9. Proposed Taxonomy and Analysis
10. Summary and Recommendations
This section will provide recommendation about using described best
practices and solutions.
