Building Dynamic Computing Infrastructures over Distributed Clouds

摘要

The emergence of cloud computing infrastructures brings new ways to build and manage computing systems, with the flexibility offered by virtualization technologies. In this context, this PhD thesis focuses on two principal objectives. First, leveraging virtualization and cloud computing infrastructures to build distributed large scale computing platforms from multiple cloud providers, allowing to run software requiring large amounts of computation power. Second, developing mechanisms to make these infrastructures more dynamic. These mechanisms, providing inter-cloud live migration, offer new ways to exploit the inherent dynamic nature of distributed clouds.
