However security remains the biggest barrier in the adoption of cloud, and with the advent of multi-cloud and federated clouds in practice security concerns are for applications and data in the cloud. This paper proposes security as a value added service, provisioned dynamically during deployment and operation management of an application in multi-cloud and federated clouds. This paper specifically considers a data protection and a host & application protection solution that are offered as a SaaS application, to validate the security services in a multi-cloud and federated cloud environment. This paper shares our experiences of validating these security services over a geographically distributed, large scale, multi-cloud and federated cloud infrastructure. %G English %Z TC 11 %Z WG 11.11 %2 https://inria.hal.science/hal-01416233/document %2 https://inria.hal.science/hal-01416233/file/337890_1_En_21_Chapter.pdf %L hal-01416233 %U https://inria.hal.science/hal-01416233 %~ IFIP %~ IFIP-AICT %~ IFIP-TC %~ IFIP-TC11 %~ IFIP-TM %~ IFIP-WG11-11 %~ IFIP-AICT-454
