Monitoring as a service for SDN Based cloud data centers

The recent rise of cloud applications, representing large complex modern distributed services, has made performance monitoring a major issue. In our research, we propose that the cloud infrastructure can provide Monitoring as a Service to cloud applications in a transparent manner without the need for software instrumentation and allowing for a flexible placement of logging functionality, by exploiting SDN and NVF. Our proposal consists of two major components: the first one is a prototype architecture design and implementation for non-intrusive application performance monitoring with a comprehensive performance evaluation to highlight the trade-offs. The second proposal is dynamic application topology detection which gives the cloud users a global view of how their application is executing across services.
