To enhance the reliability of cloud services, many application providers leverage multiple cloud providers for redundancy. Unfortunately, such techniques fail to recognize that seemingly independent redundant clouds may share third-party infrastructure components, e.g., power sources and Internet routers, which could potentially undermine this redundancy. This paper presents iRec, a cloud independence recommender system. iRec recommends at best-effort independent redundancy services to application providers based on their requirements, minimizing costly and ineffective redundancy deployments. At iRec's heart lies a novel protocol that calculates the weighted number of overlapping infrastructure components among different cloud providers, while preserving the secrecy of each cloud provider's proprietary information.
