Add seminar to my diary


Multitenancy becomes common as an increasing amount of applications runs in clouds. However, the certainty of running applications in a fully controlled administrative domain is lost in the move. How to ensure that the data and business logic are handled faithfully becomes an issue. In this talk I will describe a state machine maintained outside of a multitenant platform to make the platform accountable. I will introduce a mechanism to support accountability for a multitenant database with a centralized external service as well as options of implementing a decentralized virtual accountability service via collaborative monitoring. The characteristics of the mechanism are demonstrated through experiments in Amazon EC2.
