APIs – Extend the Reach of your Business

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

APIs are and Extension Of SOA
Approach 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

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.
