Traditionally, enterprise applications have been monolithic, meaning all the functionality is bound together in a single code base. This has several structural disadvantages. First, teams must build and test the entire application as a unit, which hampers developer productivity. Cloud-native architecture, in contrast, is inherently modular and distributed. Building software this way is similar to constructing a structure out of LEGO blocks. Teams can assemble prebuilt components without needing long testing times. Additionally, teams can modularize applications so developers can work on different pieces in parallel. This adds up to a significant productivity boost for developers
