Last year, a handful of Zalando engineers came up with an innovative solution for this exact problem - project Mosaic. Mosaic is a new architecture for websites where microservices are used in the entire stack, all the way to the frontend.
We’ve published Mosaic as open source. Its main components are:
- Skipper - an HTTP router with runtime update of routes
- Tailor - a streaming layout service with runtime update of templates
The network is the glue putting it all together.
In this talk we want to share our motivation to build Mosaic, how to perform such migration without downtime, and the advantages it has to offer to other organizations, regardless of their size.
We'll go through the operational details about Skipper and how it can be customized to answer many other different requirements. I'll also describe in detail how Tailor can dramatically improve the perceived performance of your website by streaming frontend content, from multiple fragments, in parallel.
