Support Services for Applications Execution in Multi-clouds Environments

摘要

Deploying and running applications in multi-cloud environments is a challenging task for a number of reasons: different configuration parameters are needed for differentcloud environments, application's artefacts may vary across technologies or cloud providers, services provided at IaaS level vary from one cloud provider to another. This paper introduces a run-time platform that enables the deploymentand execution of applications on multi-clouds with guaranteed quality of service (QoS), and details the underlying services ofthe unified layer responsible for connecting to multiple IaaScloud providers, which avoids runtime lock-in and simplifies the management of cloud applications.
