N2 - Issues characterizing cloud computing such as security, interoperability, and vendor
lock-in are likely to act as inhibitors of the widespread adoption of cloud computing in
organizations. These issues call for relational and contractual mechanisms to articulate the
desired outcomes of service provisioning and acceptable behavior of service recipients and
providers. In this paper we focus on the contractual mechanisms for this purpose and, more
specifically, Service Level Agreements (SLA). We have conducted a qualitative study
interviewing industry experts to understand the extent to which SLA specifications in traditional
IT services outsourcing can be applied in cloud computing, identifying elements becoming
redundant or not applicable, and new elements capturing the specificity of the business
relationships entailed by cloud computing. Our study results in a detailed SLA specification for
different cloud computing deployment models, i.e. private and public cloud, and in a framework
investigating the role of SLA elements in the decision making process for cloud computing
outsourcing.
