Serverless is coming. However, it transformed the IT landscape already. Advocates of that kind of solutions are claiming that those solutions are cost-efficient, less problematic to maintain (again - cheaper, smaller OPEX), and modern (we like those arguments in IT, don't we?). The truth is that there is a much more significant advantage of embracing serverless. Money is not everything, as there is at least one more precious resource: time. I want to present an interesting case study, how to significantly reduce time to market with using serverless powered by AWS ecosystem. As always, context is king, and when it comes to building an MVP, serverless provides a tremendous advantage in focusing on business value first. The goal of the talk is to show pitfalls and fallacies related to developing serverless applications but still delivering an MVP (minimum viable product) without sacrificing quality or further enhancements.
