Visiting Research Engineer

Research Interests

My research interest is on the general area of deploying data-intensive applications on cloud environments. In particular, trade-offs (e.g. performance, scalability, and data consistency) of the different approaches of hosting the database tier (e.g. DaaS, NoSQL systems, virtualized database servers) of software applications in public cloud platforms. aiming of bridging the gaps between the SLA requirements of consumer applications and the SLA guarantees of cloud providers.
