Talk Title: AppInsight: Mobile App Performance Monitoring in the Wild
Series: CS Colloquium
Abstract: The mobile-app marketplace is highly competitive. To maintain and improve the quality of their apps, developers need data about how their app is performing in the wild. The asynchronous, multi-threaded nature of mobile apps makes tracing difficult. The difficulties are compounded by the resource limitations inherent in the mobile platform. To address this challenge, we develop AppInsight, a system that instruments mobile-app binaries to automatically identify the critical path in user transactions, across asynchronous-call boundaries. AppInsight is lightweight, it does not require any input from the developer, and it does not require any changes to the OS. We used AppInsight to instrument 30 marketplace apps, and carried out a field trial with 30 users for over 4 months. We report on the characteristics of the critical paths that AppInsight found in this data. We also give real-world examples of how AppInsight helped developers improve the quality of their app.

CS Colloquium: Anees Shaikh (IBM): Software-based Services for Cloud Networks

Speaker: Anees Shaikh , IBM
Talk Title: Software-based Services for Cloud Networks
Series: CS Colloquium
Abstract: Software-defined networking (SDN) aims to provide a well-defined programming and automation interface to network devices. In moving network control and functionality to software running on standard server platforms, SDNs depart from the traditional, vertically integrated model of network hardware and software. We view SDNs as a new opportunity for supporting more seamless integration of networks with IT processes, and for providing higher-value network services.
In this talk, after describing the SDN model and our approach for building SDNs, we will focus on the problem of providing networking services for cloud computing platforms. As more enterprises look to leverage the cost and flexibility advantages of cloud computing, the lack of rich networking support remains a challenge. We will discuss the requirements of enterprise line-of-business applications for additional network functions in the cloud, and describe our research efforts to develop networking services for multi-tenant enterprise clouds using software-defined networking techniques.
