The Role of API Gateways in Microservice Architectures

Despite their differences in nomenclature, newly emerging service meshesaren’t all that different that API Gateways, and the similarities between the two will continue to grow over time, so predicts Marco Palladino, Chief Technology Officer of API Gateway provider Mashape.

The two technologies actually offer quite similar functionality, Palladino noted.
