Multitenant databases achieve cost efficiency through the consolidation of multiple small tenants. However, performance isolation is an inherent problem in multitenant databases due to resource sharing among the tenants. That is, a bursty workload from a co-located tenant, i.e., a noisy neighbor, may affect the performance of the other tenants sharing the same system resources. We address this issue by using a load balancing method that is based on database replica swap. Unlike the traditional data migration-based load balancing, replica swap-based load balancing does not incur data movement, which makes it highly resource- and time-efficient. We propose a novel method of choosing which tenants should be subject to swaps. Our experimental results show that swap-based load balancing effectively reduces the number of SLA violations, which is the main performance metric we choose.
