This article is a part of a series that looks at serverless from diverse points of view and provides pragmatic guides that help in adopting serverless architecture, tackling practical challenges in serverless, and discussing how serverless enables reactive event-driven architectures. The articles stay clear of a Cloud provider serverless services, only referring to those in examples (AWS being a common reference).  

As discussed in the article, “Serverless Reference Architecture,” serverless finds its footprint in diverse workload patterns. Web is the most common and ubiquitous application type, allowing the delivery of content and business journeys over the internet. This article details 5 patterns of serverless web architecture, with details on the motivation and impacts of using the pattern. The designs are presented in a cloud/vendor-neutral way with a supplementary AWS implementation. Given the range of services across all major cloud providers, the same pattern can be implemented across all. Finally, the details include a few potential pitfalls and best practices.
