Bio

Ramakrishna Kotla's research seeks to improve various aspects of practical systems: performance, reliability, and security. His research interests span a broad range of topics related to systems, including distributed systems, operating systems, fault tolerance, and storage systems. He recieved his MS and PhD in Computer Engineering from the University of Texas at Austin, where he co-founded and led Zyzzyva and SafeStore projects.  Prior to that he received B.Tech degree in ECE from IIT Kharagpur.

SafeStore provides efficient mechanisms to build durable and practical storage systems using cloud storage service providers such as Microsoft's Azure and Amazon's S3.  Zyzzyva uses speculation to implement reliable and high performance replicated services by minimizing the overheads of Byzantine Fault Tolerance technique.  Zyzzyva and SafeStore received best paper awards at SOSP 2007 and USENIX 2007 conferences respectively. His old home page can be accessed here for additional information (including source code) on Zyzzyva and SafeStore projects. 

Prior to that, he has also worked on OS issues for multi/many-core processors and high speed packet classification techniques.
