The document discusses pattern-driven enterprise architecture presented by Asanka Abeysinghe at QCon Sao Paulo 2015, focusing on managing IT complexity and improving efficiency through architectural principles. It highlights service-oriented architecture (SOA), next-gen middleware, and the importance of integration in modern applications, termed 'systems of systems.' The presentation also outlines approaches to architecture development, including cloud adoption and connecting legacy systems to current technologies.

3. 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

4. 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.”

6. Service Oriented Architecture (SOA)

“Architecture paradigm to build
highly loosely coupled distributed
systems”

7. SOA cont….

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

 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

Next-Gen Middleware
 Big-3
o Mobile
o Social
o Cloud
 APIs
 Big Data
 DevOps

15. Modern Applications are
Systems of Systems

16. Gartner View of Systems of Systems

17. 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.

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

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

42. Connect Old-IT and New-IT
Architecture

43. People

 Engage
 Empower
 Accountable
 Iterative
