Business APIs

“APIs provide a way to make resources

available for internal and external

partners to access information and

services.”

API Architecture

An API is a business capability delivered over the Internet

to internal or external consumers

• Network accessible function

• Available using standard web protocols

• With well-defined interfaces

• Designed for access by third-parties

A Managed API is:

• Actively advertised and subscribe-able

• Exhibits high Quality of Service (QoS)

• Available with Service Level Agreements (SLAs)

• Secured, authenticated, authorized and protected

• Monitored and monetized with analytics

Some Statistics

• Twitter : More than 15 billion calls per day 75% through APIs

• Netflix : More than 1 billion calls per day

• Facebook : More than 5 billion calls per day

• Amazon : More than 260 billion objects store in S3

• eBay : More than 2 billion transactions per day (using the WSO2 ESB)

“APIs create a new relationship opportunity – B2D; Business to Developer, that creates

direct B2C, B2B and indirect B2C relations”

API Opportunity

•Create APIs

• WSO2 Application Server, Data Services Server and ESB

•Find and subscribe/buy APIs

• API Store and Governance

•Manage, secure and protect APIs

• API Management and Gateway

•Monitor and Monetize APIs

• API Monitoring and Analytics

•Develop, host and run API-based applications in a Platform-as-a-Service

• WSO2 Stratos and Cloud Development Platform

• API Cloud

The API Platform Architecture

Business Design of the APIs • Know the consumer

• Who will use the APIs (both developers and final end-user)?

• What type of applications will use the APIs?

• What business assets will be delivered?

• Maintain Operational Control

• What Quality of Service is expected?

• Who can access the assets?

• Remember Usability and Monetization

• How will the API expose business assets?

• How will you demonstrate business value via direct revenue, chargeback, or

showback?

API Ecosystem Model

•From SOA lessons learned, best practices roles

•API Publisher

• Builds, publishes, manages, and versions API

• Understand business and technical requirements

• Cares about usage and scaling

• Seeks feedback, ratings, usage

•API Manager

•Promotes and encourages consumers to adopt API

•Determines usage patterns and how to best monetize asset

•Monitors and secures

•API Consumer

•Understands the interface definition

•Subscribes and connects application to API

•Monitors own usage and cost basis

•Provides feedback and ratings

API Publisher •Publish easily consumable APIs

•Increase API accessibility, availability, reliability, and security

•Drive API adoption by building communities and promoting APIs

API Consumer

•Identify API matching project requirements

•Evaluate API and rapidly compose solution

•Assess service level agreement and cost

•Socialize project requirements with API Publisher

API Manager

•Meter, rate limit, and monetize investment

•Promote and enforce API lifecycle best practices

•Optimize API portfolio and reduce custom development

•Identify usage patterns, successful providers, and business opportunity

Architect’s View of API Objectives

API Publisher

•Quickly develop and publish secure RESTful APIs

•Associate service level policies and monetization rates

•Promote samples, how-to-guides, and roadmaps

•Evolve and version service

API Consumer

•Register as an API consumer

•Review API documentation and match project requirements

•Obtain API key, integrate with API, test API

•Subscribe to API at a specific service level and pricing rate

API Manager

•Follow best practice API lifecycle workflow

•Version API

•Request API features and file issue

•Automated migration across lifecycle environments (e.g. Dev/QA/Prod)

Developer’s View of API Objectives

Built on Proven Components

• API Management Platform leverages WSO2 proven components:

o WSO2 ESB

used as API Gateway by eBay, AAA, and others. eBay handles > 1 billion API calls/day

o WSO2 Governance Registry

used by British Airways, Intermountain Healthcare, and many others

o WSO2 Identity Server

used by Citigroup, Federal Home Loan Bank of SF, US Navy and others
