What is it about?
Information technology (IT) departments are increasingly challenged to replace legacy applications with novel public cloud software as a service (SaaS) to innovate the organization's business processes. The resulting hybrid cloud is formed by integrating the added SaaS with existing IT services. The decision to adopt SaaS in such a hybrid cloud service composition requires appropriate consideration of the respective service level agreements (SLA) to ensure the proper execution of the supported business process. This research paper identifies economic and technical issues in hybrid cloud arising from SaaS adoption and discusses challenges and existing solutions.

Why is it important?
Previous studies focused strongly on cloud service selection or SLA negotiation rather than functionally desired SaaS adoption from the perspective of the hybrid cloud provider as integrator. A structured literature survey revealed that 52 issues in 36 identified publications are transferable to this context. These issues were classified in six different challenges.
