Cloud Computing has an expanding future in both business and Information
Technology. With the expanding hybrid cloud model offering better services and
convenience there are also a number of security problems associated with cloud
standardization, multi-tenancy third party privity/sub-contracting, data-controller, outages, availability, monitoring and the service level agreements. This paper focuses on
Hybrid Cloud Computing security in the context of a Tenant-Vendor-Third-Party
environment and service level agreements. Limitations, opportunities and suggestions to mitigate the security risks are discussed and summarized.
