# Scaling Applications with Microfrontends # General Track
Once upon a time, you had one Single Page Application using a Monolith Backend that relies on a Database. Then you started getting some users and suddenly you needed multiple instances of your Monolith Backend and more replicas of your Database. Your user base kept growing and also your development team was growing, so you split your Monolith backend into Microservices with their own Databases.
You’re very happy about the situation until you realize that the same problem you had on the backend it’s now on the frontend. Multiple teams are working on the same codebase, it’s hard to do frequent releases and there’re a lot of cross-team communications that slow things down.
At DAZN we battle-tested the Microfrontends architecture leveraging feature like blue-green deployments in the frontend, framework agnostic teams and drastically reduced cross-team dependencies.
