Cloud native applications are popular these days. They promise superior reliability and almost arbitrary scalability. They follow three key principles: they are built and composed as microservices. They are packaged and distributed in containers. The containers are executed dynamically in the cloud. But which technology is best to build this kind of application? This talk […]
