Digital Platforms 

Platform 5 “A platform is a support structure that increases the effectiveness of a community.” - Dave Grey Source: The Connected Company by Dave Gray, Thomas Vander Wal

Taking APIs to production 

Most of the time We think of getting an API to the production means: ● Source and API Management (APIM) software ● Configure the APIM ● Secure the API ● Test the API ● Deploy to production 10

Microservices patterns 

What are Microservices? 13 Microservices - also known as the microservice architecture - is an architectural style that structures an application as a collection of services that are: ● Independently deployable ● Loosely coupled ● Organized around business capabilities ● Owned by a small team Credits: microservices.io 

Microservices Patterns ● Decomposition: ⦿ domain, sub-domains, strangler ● Integration: ⦿ API Gateway, Aggregator, UI Composition ● Database ⦿ Database per Service, Shared, Saga, CQRS ● Observability ⦿ Tracing, Logging, Healthchecks ● Cross-cutting ⦿ External configurations, Service discovery, Blue/green and Canary style deployments, Circuit breakers 14
