I'm a M.Sc Computer-Science student (since 2011/03) in the Technion, working under the guidance of Prof. Danny Raz. I holds a B.Sc in Computer Science, also from the Technion, where I started my studies at the age of 22, after a 3 years service at the Israeli Defence Force. In the past 4 years I've been an intern at the Haifa IBM Research labs, working on various practical and theoretical aspects of Systems Virtualization and Cloud Computing, a field which I've found to present exiting opportunities and challenges.

My research looks into the problem of High Availability in Clouds. As cloud computing becomes more popular, data center's size increases and the need to manage them efficiently takes center stage. As services are out sourced to a cloud environment, the cloud provider usually commits on curtain level of availability, as part of the Service Level Agreement (SLA). In reality, many cloud providers find it hard to commit to high levels of availability. Common up-time guaranties are at the level of 99.5% annual commitment (corresponding to 1.8 days of VM unavailability annually). This is usually the result of none negligible machine failure rates as well as network malfunctions, software bugs and service overloads; all of which are common at large computing infrastructures.

In this research I'm looking into ways to smartly place VMs to maximize their availability.
