COMMON CHALLENGES INMODERN APPLICATION DEVELOPMENT
Integrate SaaS Apps
Extend Legacy Apps
Customer and Partner Access
IoT Devices and Architectures
Enable Customer Facing Apps via Many Channels
Data Access for Business Users
Building Scalable Cloud Native Applications

CAMPBELL'S SOUP: APIs LEAD TO A BREAKTHROUGH NEW CUSTOMER CHANNEL
● Initially created a Nutrition and Recipes API to be used by marketing agencies and application designers
● Reaching new audiences with the recipe application “Campbell's Kitchen” on the Amazon Echo device
● Very high value brand interaction in the customers’ residences
● Leading to possible Integration with Amazon shopping cart to provision for recipes

INTEGRATION AND APIs DRIVE AIR TRAVEL INNOVATION
● Schiphol Airport aims for world class traveller experiences
● Using Integration to create the right API endpoints and then putting them in the hands of partners creates an extended team to deliver innovation
● Flight, baggage, reservation, and other data are available throughout the airport and to all partners
● APIs through API Management provide the foundation for seamless handoff between the airport and its partners
10
QANTAS - DRIVING ORGANIZATIONAL CHANGE THROUGH APIS
● Promoted a change to API First 2-3 years ago to identify key resources and make them more reusable
● Internal APIs are changing development patterns inside large organizations
● Stable APIs are creating new opportunities to innovate for internal developers and outsourced teams
● Powering mobile applications, integrations and (shortly) partners
11
● APIs (and bounded contexts) can enhance architecture capabilities that allow for independent testing and design changes
○ Correlated to higher performing organizations● Inverse Conway Maneuver - teams and org structure evolve to attain desired
architecture● Benefits derived when teams can make large design changes with little to no
communication with other teams
● Critical that APIs are stable, well documented, and managed like a SaaS / Product

API PROGRAM STRATEGIES
1. Focus on the value of the API2. Obsess about developer experience (DX)3. Remember API retirement and change

THE API OWNER’S MANUAL
● Captured learning from successful API teams
● Reinforced by recent experience

BUSINESS (OR VALUE!) MODEL
● Different types of value (monetary, brand, loyalty) etc. are all valid
● Adoption of an API is often just as expensive as provision
● Think of the Apple Store value creation equation
Operator BenefitUser Benefit
3scale API Management21
OBSESS ABOUT DEVELOPER EXPERIENCE
Time To First Hello World
● Make it very clear what the API does
● Provide instant signup● Provide free access● Be transparent about pricing● Having great documentation● Having the means to test the
API Live
3scale API Management22
RETIREMENT AND CHANGE MANAGEMENT
● Often Forgotten● Just as critical as
launch● Communicate
Roadmaps, Communicate Change
● Provide Migration opportunities
What To Measure
Bad Metrics
Number of APIs Number of API Calls Number of Integrations
Number of Containers Number of Servers
Number of Lunch & Learns
Good Metrics
Number of Apps Supported
Number of complete Use Cases Number of Users
Dollar Value of Business
Speed of Application
development
Speed of API Deployment
Take Aways...

● Incremental transformation● Creating a new organizational
capability● Treating APIs as products rather
than resources

THANK YOU FOR YOUR TIME!
● APIs will very likely be a key architectural component for most organizations
● Red Hat is investing heavily and aiming to be a long term partner
● Agile Integration, Container Management, and API Management will be a key architectural pillars for the next 3-5 years

2. BUSINESS (OR VALUE!) MODEL
● Don’t leave adoption benefit to chance
● Decide what is in and out of scope for your users
● This is even true inside an organization
1. Create Value
2. Do not attempt to capture all the value you create
3scale API Management32
3. FOCUS ON USERS AND USABILITY
“APIs as Products” is a key meme
Re-check who your Users Really are
Make Sure Genuine Use-Cases are Fulfilled
Evolve Interfaces, Documentation and
experience via feedback
3scale API Management33
3. FOCUS ON USERS AND USABILITY1. Data Format: Support of XML, JSON, proprietary formats, or a combination.
2. Method Structure: Methods can be very generic, returning a broad set of data, or very specific to allow for targeted requests. Methods are also usually called in a certain sequence to achieve certain use cases.
3. Data Model: The underlying data model can be very similar or very different to what is actually exposed via the API. This has an impact on usability, as well as maintainability.
4. Authentication: Different authentication mechanisms have different strengths and weaknesses. The most suitable one depends on the context.
5. Usage Policies: Rights and quotas for developers should be easy to understand and work with.

Empower teams to launch and manage
Provide Governance, Guidance, Support

6. GO BEYOND MARKETING 101
● Internal and External APIs need Marketing
● Important to diffuse: ○ What resources are
available○ What use-cases are
intended○ Highlight successful users
● The things to try:○ Puzzles○ SDKs○ Discovery / Registries○ Co-marketing with
partners
