Presentation at Red Hat's Microservices, APIs, containers and integration by Keith Balbo.

1. AN API-FOCUSED APPROACH FOR
AGILE INTEGRATION
Keith Babo
Red Hat
Product Management Director - Integration

2. THREE THINGS
Avoid accidental API architectures
Understand the role of integration in API-centric architectures
Get “hands on” with Red Hat Integration

3. Strategy
API-CENTRIC INTEGRATION LIFECYCLE
Design Implement Deploy Manage

4. API STRATEGY

* Gateway layer for services
* Access and policy control
* Developer onboarding
* Analytics
* Monetization
* Scales independent of other layers

9. CLIENT-FOCUSED
❏ Design with the API client in mind
❏ Design with tooling fit for purpose
❏ Collaborate ASAP
VALIDATE EARLY
❏ Use API mocking for early feedback
❏ Skeleton implementation can be just as good as a
mock
FAVOR
INTEROPERABILITY
❏ Create API definitions based on standards in open
communities
❏ Maximize tool portability and client generation
Design Implement Deploy Manage

10. DEMO TIME!

11. HONOR THE TRUTH
❏ API Definition is the source of truth
❏ Favor generation over translation
WHICH PERSONA?
❏ Developer
❏ Non-developer
NOT ALL APIs ARE
THE SAME
❏ Standalone
❏ Data API
❏ Orchestration
❏ Event Bridge
❏ Legacy Facade
Design Implement Deploy Manage

12. DEMO TIME!

13. CONTAINERS
❏ Best way to develop services (polyglot, portability,
availability, service wiring, advanced deployment, …)
❏ Maximize inner vs. outer architecture pattern
HYBRID
ENVIRONMENT
❏ Support integration and management of APIs living
outside containerized environment
❏ Consistent architecture across private, public, and
managed cloud
AUTOMATE
❏ API-driven infrastructure services
❏ Ability to automate application and infrastructure
services in a single pipeline
Design Implement Deploy Manage

14. DEMO TIME!

15. CONTROL
❏ Securing APIs
❏ Traffic flow control via policy
❏ Policy extensibility
VISIBILITY
❏ Developer onboarding and engagement
❏ Traffic and policy alerts
❏ Use analytics to understand how APIs are tracking
against business objectives
FLEXIBILITY
❏ Centralized management and distributed enforcement
❏ API management architecture must span multiple
environments
Design Implement Deploy Manage

16. DEMO TIME!
