– The API Economy will become a $2.2 trillion market by 2018,analysts estimate
– 70% of business transactions in enterprises today touch IBM z Systems
§ These significant business opportunities are tempered by technical challenges including integration,
security and cost-effective delivery, at the speed-of-digital
§ Join IBM world experts at this 3-day client event, exploring topics including:
– The evolution to the API economy
– What makes a good API? Best practices for the API world
– Create world-class APIs for speedy access to core business logic
– Secure, govern and enhance APIs to reach new markets
– Consumers of APIs in practice: Mobile,Cloud and Internet of Things (IoT)

“Mainframe data feels different”
A common misconception:
§ “Mainframe data is difficult to access”
§ “I want to discover my own services”
§ “I don’t want to be bound by formalised COBOL (or even XML!) data structures”
§ “Solution: let’s hold the data with easier access… maybe a cache/ noSQL DB?”
Certainly not true or necessary!
With technologies like z/OS Connect Enterprise Edition & IBM API Connect…
…contemporary developers can now consume mainframe services in precisely
the same way as a Google Maps or Facebook API

IBM API Connect
So, we have APIs into z Systems resources…

IBM API Connect
• Expose them?
• Rate-limit them?
• Socialise them?
• Secure them?
• Monitize them?
• Integrate them?
• ...

IBM API Connect
… is a full-featured management solution that addresses all aspects of the API lifecycle for
both on-premises and cloud environments.

Individuals in clients and partners who would find this three day event of interest:
§ Architect communities
– Integration Architects
– Enterprise Architects
§ IT Strategists
§ Mainframe application owners
§ API Developers/ specialists
Attendees only need a general awareness ofweb services and API principles,with introduction and progressive technical
depth being developed over the course of the three days. An architectural understanding ofz Systems environments,such as
CICS and DB2, is recommended - however there is no requirementfor attendees to have had hands-on practical experience
of these technologies.
The primary technologies thatwill be discussed and shown over the course of the three days are: API Connect, z/OS
ConnectEnterprise Edition and DataPower,in the context of subsystems such as CICS, and cloud environments such as IBM
BlueMix.The idea is that attendees will develop an understanding ofhow mainframe applications are now directly
consumable as a set of REST APIs - in much the same way as a Google API.
