Abstract:
The live virtual machines migration is a widely used technique in cloud computing environments because it is not necessary to stop services hosted on the migrated virtual machines. This paper aims to conduct an experimental and quantitative study on the migration of virtual machines through the evaluation of different scenarios. For this, a fully virtualized computing environment was implemented with the purpose of performing experiments that allow to analyze the influence of the live migration process in the performance of the services offered by the virtual machines migrated. The following metrics were evaluated: number of requests per second, server response time, throughput, latency and total migration time. Benchmarks ab- Apache Benchmark and YCSB-Yahoo! Cloud Serving Benchmark were used to generate the workload for the Web services and Database (Cassandra), respectively. The results obtained revealed that during the migration period, the services considered presented a reduction in their performance, but although there is a decrease, the service is not interrupted, thus complying with the principles of live migration.
