| Content Summary | Cloud computing offers an innovative business model for organizations to adopt IT services at a reduced cost with increased reliability and scalability. Adopting a cloud solution means binding to a specific platform and vendor, using specific protocols, standards and tools of the cloud and finally, running into a vendor lock-in situation. The fear of vendor lock-in is often cited as a major impediment to cloud service adoption. If the provider decides to raise its prices or change its security policies, the customer may have to consider to move his workloads to another provider. In this work we focus on the automatic migration requirements in Openstack systems and as a use case we present a mechanism for Virtual Machine (VM) migration (or of their running instances) between Openstack and KVM virtualization and another cloud platform that runs a different Virtualization engine (Stratogen and VMware is our case). The standards approach is to freeze the running instance of a VM and restart it under the new environment. We examined the requirements for successful migration and the conclusion is that migration is not always fully automatic as it might need lots of parameter tuning depending on differences in the type of virtualization engines used at source and target environments (a task that can be performed by a specialized expert). To alleviate the requirement of human intervention in the loop, we suggest using containers as the underlying virtualization technology. We propose a mechanism that implements migration using containers in a few steps and we run a series of experiments to show proof of concept. As a conclusion, the later technology proved to be feasible and more promising although it is still not fully supported by infrastructure (operating system) tools that allow migration independent of the state of the underlying operating system kernel at the time of transfer. | en |
