“…The performance of the proposed EMT-M algorithm is studied in a simulated environment, as shown in Fig. 2, to verify its quality by comparing it with previously used algorithms [8,9,13]. The proposed simulation environment consists of 8 Fujitsu esprimo-P556 sites grouped into 3 groups using the inter-site communication cost [6] shown in Table 3.…”

“…According to [8,9], the violated tenant T-D1 will be migrated to site 4, which has the max average free time. In addition, according to our previous migration algorithm [13], the violated tenant T-D1 is migrated to site 7 in cluster 3, which has the maximum number of SLA violation. According to our proposed EMT-M algorithm, we use both the number of SLA violations and the variance rate to select the optimal site to migrate the violated tenant.…”

“…To overcome the limitations of existing literature highlighted by the above survey, this research proposes an enhanced multi-tenant migration algorithm called EMT-M algorithm, which is an extension of the work proposed in [13]. The main contribution in this extended research is adding a new parameter in the migration process to mitigate the SLA violations.…”

“…The main contribution in this extended research is adding a new parameter in the migration process to mitigate the SLA violations. In our previous work [13], we use the number of SLA violations to detect the source of the violation to mitigate the violation crisis.…”

“…However, Site 2 has the maximum free space and the minimum number of tenants. To solve the limitation of existing literature and enhance our previous migration algorithm [13], we propose an enhanced multi-tenant migration algorithm called EMT-M. The proposed EMT-M algorithm uses the number of SLA violations of each client site and the variance rate to select the optimal site to migrate the violated tenant.…”

In a multi-tenant business environment, tenants share the same applications and databases to store their data. Due to the widespread use of a multi-tenant environment, the service providers face difficult challenges daily. These challenges are condensed in how to guarantee the quality of service provided to tenants, which are documented in a formal document known as a Service Level Agreement (SLA). In addition, SLA should consider the irregular patterns of workload of tenants which may affect the level of guarantee. In this research, an Enhanced Multi-Tenant Database Management System (EMT DBMS) is proposed. In addition, an Enhanced Multi-tenant Migration Algorithm called EMT-M is presented, which aims to migrate the violated tenants depending on both the number of SLA violations and the variance rate. Experimental results prove that the proposed EMT-M algorithm is ideal for International Journal of Intelligent Computing and Information Sciences https://ijicis.journals.ekb.eg/ 97 A.E. Abdel Raouf et al. migrating violated tenants, as it reduces the number of SLA violations compared to previous migration algorithms.
