Upscaling Messaging and Stateful Computation

Large-scale, production-grade cloud applications are no longer black boxes for academic researchers. They are observable subjects under test in an increasing number of projects, with the aim to quantify and improve their runtime characteristics, including performance. With more meaningful measurements available, data-driven approaches have matured and advanced the knowledge in particular around conventional stateless workloads such as functions and containers. A few less explored areas still exist. They are fueled by the increasing number of atypical function deployments for instance in message brokers, in intelligent switches and in blockchains. This talk summarises reference architectures for large-scale applications, sometimes resulting in nation-scale deployments, discusses performance numbers in this context, and elaborates on whether more focus on performance is needed.
