Review On Security Based On Multiple Cloud Computing
Cloud service provider basically provides Software, Platform and infrastructure as service to the user on pay-peruse
basis. When the user gains a service from a cloud gets vendor lock-in and has to avail all services from a single cloud
provider, while data confidentiality solutions for paradigm are still immature. As organizations are now adopting the cloud
environment the cloud service providers are now moving towards a new concept i.e. multiple cloud where a user can utilize
services from multiple cloud service provider. We proposed secured proxy-based multi-cloud computing framework allows
dynamic, on the- fly collaborations and resource sharing among cloud-based services, addressing trust, policy, and privacy
issues. We integrates cloud with data confidentiality and the possibility of executing concurrent operations on encrypted
data. These multi-clouds are organized by an agreement between different service providers to provide a functionalities to
the client. Multiple cloud where a user can utilize services from multiple cloud service provider.
