Abstract
In the past, enterprise systems were created with app servers for scalability, security and
integration. But we are now entering the generation of API Servers, providing much simpler
integration and access. This talk will focus on getting the best of both worlds – preserving your
existing software investment in app servers, while gaining the integration and access of API
Servers, with remarkable increases in business agility.

Client Server to App Servers
§ Mainframe
§ Client Server – Leverage GUI
§ App Server - Scalability
– Clustering
– Connection Pooling
– Logic (integrity, security, integration)
Powerful (and complex)

7. 7 © 2016 CA. ALL RIGHTS RESERVED.@CAWORLD #CAWORLD
Issues With Standard 3-Tiered App Server…
§ Communications – key to the App Economy
– Proprietary Protocols
– SOAP is too complex
§ Agility
– Code Intensive Logic (Integrity, Security, Integration)
– Complexity
– Architecture – where is the logic? Fat Client 2.0?
The Trouble With Triples…

API Servers – Key Requirements
§ API Logic... More than just REST
§ Logic and Integration (like App Server)
§ Leverage Current Investment
– Run in App Server (or Docker
– Leverage Existing Software
API Server ~= App Server + API Logic – Web Page Creation Services
Logic
Integration
Data
API
Nested Documents
Pagination
Optimistic Locking

Which Brings Us to the Problem
§ But it’s not…
– Backlog already high
– Every new system should be API-enabled – more work!
§ What about Fat Service?
– Repeat the Logic for every API?
Goal is Agility: Eliminate the Barriers Between Ideas and Outcomes
