Developing and deploying multiple releases per day, or per hour is a challenge, especially when building the infrastructure as code, as well as the rest of the app. Architectural designs have changed from monolithic applications to distributed microservices with fine granularity, isolated deployment and lightweight protocols and engaging customers over more channels than ever, from mobile, through chatbots to virtual and augmented reality. An API first approach is critical to tying all this together, allowing cloud native applications to access data and processes, enabling collaboration between front-end and back-end developers. Microservices and chatbots are driving a real need for all enterprises to adopt an API-first strategy to deliver great features faster.

Change continues, but what has made life interesting?
Hard coded Elements
12-18 month app dev cycle
Centralised teams
Monolithic
Building just another app
Developing functionality first
Dynamic, blended technologies and 12 factor
Zero-time dev cycle (days or hours)
Distributed teams, different preferences
Smaller, independent components
Create engaging interfaces
API-first design
