Abstract
This paper presents results of the ongoing development of the Cloud Services
Delivery Infrastructure (CSDI) that provides a basis for infrastructure centric
cloud services provisioning, operation and management in multi-cloud
multi-provider environment defined as a Zero Touch Provisioning, Operation and
Management (ZTP/ZTPOM) model. The presented work refers to use cases from data
intensive research that require high performance computation resources and
large storage volumes that are typically distributed between datacenters often
involving multiple cloud providers. Automation for large scale scientific (and
industrial) applications should include provisioning of both inter-cloud
network infrastructure and intra-cloud application resources. It should provide
support for the complete application operation workflow together with the
possible application infrastructure and resources changes that can occur during
the application lifecycle. The authors investigate existing technologies for
automation of the service provisioning and management processes aiming to
cross-pollinate best practices from currently disconnected domains such as
cloud based applications provisioning and multi-domain high-performance network
provisioning. The paper refers to the previous and legacy research by authors,
the Open Cloud eXchange (OCX), that has been proposed to address the last mile
problem in cloud services delivery to campuses over trans-national backbone
networks such as GEANT. OCX will serve as an integral component of the
prospective ZTP infrastructure over the GEANT network. Another important
component, the Marketplace, is defined for providing cloud services and
applications discovery (in generally intercloud environment) and may also
support additional services such as services composition and trust brokering
for establishing customer-provider federations.
