Networking projects list6/9/2023 ![]() Particularly, we elaborate a non-intrusive method to capture the dependency relationships of components, which improves the feasibility. With the help of our solution, cloud operators can find out root causes of any anomaly no matter the root causes are in the same tenant as the anomaly or from other tenants. Based on these two considerations, we propose a solution for cloud providers to help tenants to localize root causes of any anomaly. In this paper, we argue that the cloud providers are in a better position than the tenants to solve this problem, and the solution should be non-intrusive to tenants' services or applications. If the performance of a multitier service degrades, we need to find out the root causes precisely to recover the service as soon as possible. Anomalies of multitier services of one tenant running in cloud platform can be caused by the tenant's own components or performance interference from other tenants.
