Patterns 3 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…. 7 “Nothing NEW, architecture style to fix the broken architectures”

SOA runtime view 11

12  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) o Companies without integration are falling behind o Heterogeneous systems Enterprise Architecture has changed

13 Next-Gen Middleware  Big-3 o Mobile o Social o Cloud  APIs  Big Data  DevOps  Open Source Picture Credit :

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. Source: Forrester Research

Systems of Systems Functional Requirements

Supportive patterns 19  Event-Driven Architecture (EDA)  Web Oriented Architecture (WOA)  Enterprise Integration Patterns  Internet of Things (IoT)

How can I get there ?

What the Enterprise Looks Like Architecture

Identity/Access Control Architecture

Services – get the service platforms Architecture

Registry/Repository Architecture

Connectivity - internal Architecture

Connectivity - external Architecture

APIs Architecture

Monitoring, Analytics, Audits Architecture

CEP – real-time Architecture

Fill-in the Blanks Architecture

Middleware Platform 37

Do I need the entire platform ?

Beyond the middleware o Cloud o *PaaS to SaaS o Cloud native o ALM o AppFactory Private PaaS Private PaaS Public PaaS Public PaaS

Same programming model Same solution architecture Same (deployable) artifacts Cloud based deployment Cloud native applications

What will happen to the current system(s), data, people ?

Connect Old-IT and New-IT Architecture

People 43  Engage  Empower  Accountable  Iterative
