The tendency of current large distributed systems such Cloud computing is the delivery of computing as a service rather than a product.Availability is the most important properties in Cloud computing.One of central issues in Cloud environment is to provide reliable Infrastructure as a service (IaaS) with optimal availability.Since the resources or nodes become larger, increasingly dynamic and heterogeneous, the potential for failures in the systems is a significant disruptive factor.This paper proposes the twin co-existance neighbourhood (TCeN) model.It focuses on improving high availability in which it predicts future availability expectation of interdependent environment in a distributed system over an extended period of time.With less complexity, this model not only theoretical sound but also feasible for practical implementation in real environment, this technique is very cost effective with less complexity compare to other techniques.The performance results show TCeN availability outperformed the Double-replica technique(DRT) with 50% less in-term of storage overhead.Moreover, results show TCeN availability outperforms the Double-replica technique (DRT) up to 14.2% with less overhead
