“…Lock management in a multitenant cloud-hosted application is essential because if an architect misses placing a lock where required, then safety is violated. In contrast, if an architect inserts unneeded locks in a cloud-hosted application, then the performance of the system suffers due to the unnecessary synchronizations [14]. In the following, we discuss how locking is used in three important types of software development processes, and some recommendations to follow regarding achieving the required degree of multitenancy isolation.…”

Multitenancy isolation is a way of ensuring that the performance, stored data volume and access privileges required by one tenant and/or component does not affect other tenants and/or components. One of the conditions that can influence the varying degrees of isolation is when locking is enabled for a process or component that is being shared. Although the concept of locking has been extensively studied in database management, there is little or no research on how locking affects multitenancy isolation and its implications for optimizing the deployment of components of a cloud-hosted service in response to workload changes. This paper applies COMITRE (Component-based approach to Multitenancy Isolation through Request Re-routing) to evaluate the impact of enabling locking for a shared process or component of a cloud-hosted application. Results show that locking has a significant effect on the performance and resource consumption of tenants especially for operations that interact directly with the local file system of the platform used on the cloud infrastructure. We also present recommendations for achieving the required degree of multitenancy isolation when locking is enabled for three software processes: continuous integration, version control, and bug tracking.
