ABSTRACT: Mostly, cloud agreements
are signed between the consumer and the provider using online click-through
agreements. Several issues and conflicts exist in the negotiation of cloud
agreement terms due to the legal and ambiguous terms in Service Level
Agreements (SLA). Semantic knowledge applied during the formation and
negotiation of SLA can overcome these issues. Cloud SLA negotiation consists of
numerous activities such as formation of SLA templates, publishing it in
registry, verification and validation of SLA, monitoring for violation, logging
and reporting and termination. Though these activities are interleaved with
each other, semantic synchronization is still lacking. To overcome this, a
novel SLA life cycle using semantic knowledge to automate the cloud negotiation
has been formulated. Semantic web platform using ontologies is designed,
developed and evaluated. The resultant platform increases the task efficiency
of the consumer and the provider during negotiation. Precision and recall
scores for Software as a Service (SaaS), Platform as a Service (PaaS) and
Infrastructure as a Service (IaaS) SLAs were calculated. And it reveals that
applying semantic knowledge helps the extraction of meaningful answers from the
cloud actors.
