Latency-aware failover strategies for containerized web applications in distributed clouds

Yasser Aldwyan, Richard O. Sinnott

Abstract: Highlights•We present an approach for achieving availability and performance when deploying web applications in distributed Clouds.•A genetic algorithm for data center (DC) selection that factors in proximity to users and inter-DC latencies is presented.•This work focuses on the placement issue and improves end-to-end response times even in the presence of failures.•We show how latency-aware application deployment can offer higher performance and stability before and after failures.•We present results based on realistic Cloud-based experiments across the national research Cloud in Australia.
