In this presentation, Bilgin challenges the traditional definition of application portability, arguing that it now encompasses development tools, operational APIs, and patterns. The talk begins by identifying design principles essential to enhancing application portability. Next, Bilgin explores the role of portable Operational APIs, highlighting the necessity of system insight using open standards. As he transitions towards dependency and data interoperability, the talk emphasizes the impact of reducing service coupling, demonstrating this concept with Dapr and CloudEvents. The conversation culminates by underlining how embracing de facto standards, and prioritizing broadly applicable polyglot tools, lead to the creation of evolutionary architectures. At the close of this session, attendees will walk away with a good understanding of the role cloud native technologies play in creating portable multi-cloud applications built to last.
