APIs – Extend the Reach of your Business


But How Do You Extend Your Reach If Your Internal House is Not In Order?

We are Not Mature Enough

APIs are and Extension Of SOAApproach Level• API – Are a product which can have a direct or

indirect tie to revenue. • SOA Services – Are utilized to make an

enterprise more agile to break down the business process into composable parts.

Consumption Level• APIs tend to have larger number of consumers

and focuses on ease of consumption through self service

• SOA Services tends to have well known consumers and fewer of them and usually has a more detailed on-boarding processes.

Governance & Management Level• API – Focuses on product management tasks• SOA – Focuses on organization changes and

standard approaches

Technical Level• API and SOA - Requires similar runtime

management capabilities

Difference Between ESB and API GatewayESB API Gateway

System to System Integration Securely Expose, Protect and Encrypt API/Services

Includes many Adapters Light Weight Integration

Strongly Message Oriented Light Weight Orchestration

Heavy Business Process Management and Event Processing

Policy driven

A Unified API Gateway is A Good Place To Start

• Simplified architecture• Light weight • Lower skill level need to deploy, run and manage• Policy driven through configuration• Endpoints are standardized• Quick return on investment


Purpose Built ESB Might be Necessary When:

• You already have an ESB in your architecture• There is purpose built ESB that has legacy system adapters that

will make your life easier• Need assured delivery with transaction role back capabilities• Off load expensive message processing• Complex Orchestrations and Event processing• Separation of concerns in architecture (interface /

implementation)

Caution

• Be careful if you want to start by putting in a purpose built ESB first if you don’t already have one.

• You may never reach the Unified API Gateway level due to the complexity of setting up the ESB.


A Unified SOA & API Platform Become Increasingly Important

• Measure the impact of your programsAnalytics

• Build your developer and partner ecosystem

Developer Engagement

• Secure and protect your systemsGateway Services

• Simplify and speed up development

Service Integration

• Build the right services & APIs the right way

API Gateways For Internal and External Use


Most Enterprises Are Still Developing In Silos

Enterprise Architecture Teams / CoEs

Unable to effectively reach their internal or external consumers


Remove the Silo’d Barriers to Enable an Internal Developer Community


Create More Effective Applications To Reach Even More of Your Consumers


Extend the Reach of Your Enterprise Beyond Your Boarders

“Reach Consumers in ways you can’t even dream of”

Start with your internal developer community today!
