Microservices

5. Intro Cloud Native Microservices
“Microservices is an architectural approach to developing an
application as a collection of small services. Each service
implements business capabilities, runs in its own process and
communicates via an HTTP API. Each microservice can be
deployed, upgraded, scaled, and restarted independent of
other services in the application, typically as part of an
automated system.”

7. Intro Cloud Native Microservices
“Cloud-native applications are purpose built for the cloud
model. These applications—built and deployed in a rapid
cadence by small, dedicated feature teams to a platform that
offers easy scale-out and hardware decoupling—offer
organizations greater agility, resilience, and portability across
clouds.”
