Bermuda Triangle of Architecture

Enterprise Architecture

API-centric Architecture

Service Oriented Architecture

Why Architecture Matters

• Integrity and Coherence Simplifies Project Execution• Portfolio and System-of-System Views Decrease Inefficiencies• Architecture Catalog Improves Productivity and Agility

“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 Focus

Enterprise Architecture Challenges• Scope

– Project versus portfolio view– Little interest in consuming shared services and standard platforms

• Collaboration– Separate team or embedded agents– Poor visibility into projects

• Execution– Short project development cycles– Can you Build from the Blueprint

• Not invented Here Syndrome

• Everyone wants TO BE AN ARCHITECT

• Are my requirements met?

Fit services, APIs , and streams fit into the blueprint

Service Oriented Architecture

Service Oriented Architecture Focus• Loose Coupling

– Be permissive in what you accept– Separate interface from implementation

• Separation of Concerns– Identity bridging– Publish coarse grained, message-oriented interfaces

• Service-orientation– Achieve progress in portfolio breadth, depth, and adoption– Publish standard data models (80/20 rule)

Is Your Enterprise SOA Solving IT Challenges?• Potential consumers do not trust service stability, reliability,

availability, or performance• Providers have scalability concerns and lack an ability to

manage consumption• Security risks prevent publishing and offering open access• Difficult to manage requirements from multiple consumers

and coordinate release schedule• Inability to configure service per consumer• Business return requires service metering usage rates, and

billing

API-centric Architecture Focus

• Business Building Blocks• Developer Adoption• A Simple Facade

API-Centric Architecture Challenges• API design• REST/JSON to SOAP/RPC message format translation• Identity Integration• Contextual Personalization

– SLA, access privileges, monetization

Integration Building Blocks• Promotion and Collaboration

– Landing page or API Store• Communication, updates • Self-service support and direct support• Research and Development Product Ideas, Opportunities,

and Labs

• On-boarding API developers and consumers– On-demand registration and key generation– Documentation and Resources – Provide a Last Mile On-Ramp

• Interoperable interface• Tools, Mobile client SDK, Authentication, Shared Platform

Integration Building Blocks

• Delivery– Security and Quality of Service at Scale– Deployment Environments

• Measuring Business Value– Usage, SLA management, version control, re-use– Monetization

Actualizing the Enterprise SOA Architecture

• Publish service catalogue and service tiers• Incorporate demand and capacity management• Govern lifecycle management and workflow• Continuous provisioning and deployment• Enforce Service level management• Establish Collaboration channels
