API Management - Why? 1


möglich


This is why APIs do really matter today!

Today there are more than 12.000 APIs offered by companies

Generate 90% of its revenue

through APIs

APIs allow people to use third-

party websites to tap Expedias

functionality in order to book

flights, cars, and hotels

Generate 60% of its revenue with

APIs

APIs allow eBay to list its auctions

on other websites, get bidder

information about sold items,

collect feedback on transactions,

and list new items for sale

Generate 50% of its revenue with

APIs

Salesforce.com has a marketplace

(AppExchange) for apps created

by its partners that work on its

platform; they now number more

than 300

Fragile solution (each change

No APIs without Business Alignment

Aligning API Design with Key Business Goals Which assets will be made available?

How should the API make those assets available?

What kind of applications could be built against the

API?

How can developers be motivated to use the API?

How will the applications create value for the

business?

Define your API landscape with respect to Business Capabilities and

End-to-End Processes


möglich


No APIs without an API-First Design approach

How will consumers use the API?

Business APIs need to be easily understandable and appropriate for the

respective use case, e.g. don’t use SOAP interfaces for Mobile

API Design rules allow the creation of consistent APIs, which improves

Developer Experience (DX) and results

Build early, lightweight prototypes to verify your API Design assumptions can be validated based on the target persona

Changes can be made easily, because the API is not bound to real data

Short Feedback cycles From App Developers to API Designers

From API Owners to App Developers

API Management is essential for modern IT architectures

API-First Design allows rapid development results

Phase 1 Phase 2

✓ Finalized definition of the single-purpose APIs on day two in a collaborative way with Apiary

✓ Independent development of Mobile app, Mobile Backend, Backend Service and API

✓ Problem: Connectivity to the backend system, because Firewall changes took too long (4 weeks project duration, connectivity was available in week 3)

✓ Development team was not blocked because implementation of the mobile app was done against the Mock Server functionality in Apiary
