Cloud computing is a trend of technology aimed at providing on-demand services with payment based on usage. To improve the use of resources, providers adopt multi-tenant approaches, reducing the operation costs of services. Moreover, tenants have irregular workload patterns, impacting in the guarantees of quality of service, mainly due to interference between the tenants. This paper proposes an approach to improve quality of service for multi-tenant RDBMS. This approach uses migration techniques of tenants, system monitoring and benefits of cloud infrastructure to improve performance and reduce costs of the provider. We carried out experiments on performance and resource usage in order to evaluate our approach.
