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

Enterprise architecture has changed today- Less visibility to projects
- Difficult to find - Availability - Ownership - (as a result EA provides *-platforms)
- Change management- Development cycles:
- From 18 to 6 months to 3 months
Enterprise architecture has changed today- Real standards
- Technical (REST, SOAP, protobuf)- Business (ACORD, HL7, FIX, FAST)
- Integration/APIs is key (extend to connected business)- Companies without integration are falling behind- Heterogeneous systems
Evolution of architecture patterns- Object oriented : OOP- Component based : COM/DCOM/CORBA- Open distributed processing : ODP- Enterprise application integration : EAI- Service oriented : SOA
- Event driven : EDA- Resource oriented : ROA- Web oriented : WOA- Microservice : MSA
SOA : “Architecture paradigm to build highly loosely coupled distributed systems”
SOA : “Nothing NEW, architecture style to fix broken architectures”

Microservice architecture (MSA) is a pattern for building and delivering service-oriented applications with two primary objectives: agility of delivery and flexibility of deployment.

MSA is not based on all-new architectural principles; it combines SOA best practices with modern application delivery tooling
and organizational disciplines.

"Micro" is a concept of scope rather than size.
A microservice must have a single purpose and be loosely coupled in
design and deployed independently of other microservices.
