    abstract = {The emergence of cloud computing has significantly changed 
  the industry’s perception of 
  infrastructure, service delivery and development models. The business use of 
  cloud based services is expanding and as a result there is a requirement for 
  analysis and research on secured use of cloud computing. The enhanced requirement 
  of enterprises lead to the evolution of combinatorial approach of cloud model 
  called ‘Hybrid Cloud’ 
  which is mix up of public and private cloud. This transition towards hybrid 
  architecture has stimulated the concerns on a critical issues and challenges 
  associated with effective implementation of security model. As a result the 
  main objective of this study is of two sets; firstly to analyze the trend, service 
  models, deployment models in cloud computing and focus shift towards hybrid 
  cloud and secondly to analyze the security issues associated with hybrid cloud 
  coupled with IaaS and possible solutions to mitigate. This review article also 
  discusses the introduction of Virtual Private Network (VPN) tunnel and data 
  encryption approach as solution to mitigate the security issues associated with 
  Hybrid Cloud Model. The VPN approach and data encryption operating in IaaS service 
  model ensures the authentication, integrity and confidentiality of involved 
  data and communications between the cloud and enterprises.}
