A generic solution for a common recurring problem. Used it before Error proof Common way to communicate : architect’s

language Catalog to pick one : feel comfortable

Enterprise Architecture

4

“Manage the complexity of the IT environment and applies principles and techniques to reduce the complexity, improve efficiencies, and reduce capital and operational expenditure.”

5

Service Oriented Architecture (SOA)

6

“Architecture paradigm to build highly loosely coupled distributed systems”

SOA cont….

“Nothing NEW, architecture style to fix the broken architectures”

SOA at kindergarten

Less visibility to projects o Difficult to find

o Availability o Ownership

Development cycles:o From 18 to 6 months to 3 months

Change management Real standards

o Technical (REST, SOAP, protobuf)o Business (ACORD, HL7, FIX, FAST)

Integration is key (extend to connected business)oCompanies without integration are falling

behindoHeterogeneous systems

Enterprise Architecture has changed

Modern Applications are Systems of Systems

Gartner View of Systems of Systems

Forrester View of Systems of Systems

Systems of record are technologies that manage and store transactions, content, and processes. 

Systems of engagement are technologies that directly support customer interactions through software.

Systems of automation are technologies that intelligently manage physical products, networks, and infrastructure.
