Wirth’s Law in the Age of Cloud and Green IT: Addressing Software Complexity for Sustainable Performance
Christian Dähn, adesso.
Abstract:
Despite exponential hardware advancements, software performance often lags behind due to increasing complexity. This keynote explores Wirth’s Law – “software gets slower more quickly than hardware gets faster” – and its implications for modern application development. We will examine how the proliferation of middleware, diverse programming languages, and complex cloud environments contribute to software degradation, resulting in slower response times and escalating resource demands. This negatively impacts operational costs and contributes to a larger carbon footprint. This talk will highlight the crucial importance of resource-efficient application design, from architectural decisions and optimized development tools to runtime performance analysis – particularly in the context of cloud computing and the growing need for Green IT initiatives.
