Enterprise Architecture Blueprint –
City of Edmond, Oklahoma
Written By: Anne Wilson Fast
1. Executive Summary
This blueprint provides a comprehensive enterprise architecture (EA) plan for the City of Edmond, Oklahoma (2025–2028). It aligns technology modernization with the City Council’s strategic goals, focusing on citizen-centric services, data-driven governance, operational efficiency, and smart-city enablement.
2. Vision & Strategic Drivers
Vision: Deliver resilient, secure, and citizen-focused IT services.
Key Drivers:
- Population growth and demand for modern services
- Digital transformation and broadband equity
- Public safety modernization
- City Council Strategic Plan alignment
3. Target Architecture Overview
The enterprise architecture is structured across six layers:
• Business Layer: Citizen services, public safety, utilities, education
• Data Layer: City Data Platform, GIS, MDM, Open Data APIs
• Applications Layer: Citizen portal, ERP/HR/Finance SaaS, GIS apps
• Integration Layer: API Gateway, Event Bus, iPaaS
• Infrastructure Layer: Hybrid cloud, IoT/Edge nodes, SCADA integration
• Security & Privacy: Zero Trust, SIEM, EDR, encryption
4. Business Capabilities
Core city capabilities supported by the EA include:
- Citizen Self-Service Portal
- Utility Billing and Smart Metering
- Public Safety CAD/RMS Integration
- Permitting and Licensing
- Education/University data exchange
- Finance, HR, and ERP modernization
5. Data Architecture
The City Data Platform (data lakehouse) enables unified data management:
- Real-time ingestion from GIS, utilities, public safety systems
- Master Data Management (MDM) for citizens, addresses, assets
- Open data APIs for public access and research use
- Data governance framework with stewardship roles
6. Application Architecture
The application portfolio follows an API-first, microservices model:
- Citizen portal (permits, utilities, payments)
- ERP/Finance SaaS solution (cloud-based)
- HR/Payroll cloud system
- GIS-driven apps for zoning, planning, and utilities
7. Integration & Middleware
Integration backbone includes:
- API Gateway with authentication and throttling
- Event Bus (Kafka/managed PubSub) for real-time data exchange
- ETL/CDC pipelines for data synchronization
8. Infrastructure & Cloud
Hybrid architecture combining cloud-first services with on-prem for latency-sensitive workloads:
- Primary workloads hosted in Azure Gov/AWS GovCloud
- Edge computing nodes for SCADA and IoT sensors
- SD-WAN across municipal sites
- Redundant fiber and fixed wireless links
9. Security Architecture
Security follows a Zero Trust model:
- Identity and Access Management (IAM) with MFA and SSO
- Security Information and Event Management (SIEM)
- Endpoint Detection & Response (EDR)
- Network segmentation, VPNs, encrypted APIs
- Disaster recovery tested quarterly
10. Roadmap (Summary)
Year 1: Foundational (cloud landing zone, IAM, data platform prototype, ERP migration)
Year 2: Capability expansion (public safety integration, smart-city IoT, citizen portal expansion)
Year 3: Optimization (open data portal, predictive analytics, broadband equity, AIOps)
11. Budget Overview
Year 1: $1.8M – cloud, IAM, citizen portal phase 1, API gateway
Year 2: $2.2M – ERP/HR SaaS, data platform expansion, smart-city pilots
Year 3: $2.5M – open data, broadband partnerships, predictive analytics
3-Year Total: ~$6.5M
12. Governance
EA Governance Board (quarterly) includes City IT, Public Safety, Utilities, UCO, Edmond Public Schools.
Procurement processes will follow RFP/RFQ with architecture compliance checkpoints.
13. KPIs & Success Metrics
- 60% of services online in 2 years
- 40% reduction in incident recovery time
- 99.95% uptime on critical systems
- 90% of households with >100 Mbps broadband
14. Risks & Mitigation
- Legacy system lock-in → phased migration strategy
- Connectivity gaps → fiber/fixed wireless redundancy
- Privacy/regulatory exposure → encryption + IAM + data governance
