Introduction to Enterprise Architecture
Enterprise Architecture (EA) is the practice of analyzing, designing, planning, and implementing enterprise analysis to successfully execute on business strategies. It provides a holistic view of an organization's IT landscape and business processes.
🏗️ What is Enterprise Architecture?
Enterprise Architecture is a comprehensive framework that describes the structure and operation of an organization. It encompasses:
- Business Architecture - Business processes, organizational structure, and capabilities
- Application Architecture - Software applications and their interactions
- Data Architecture - Data assets, management, and flow
- Technology Architecture - Hardware, software, and network infrastructure
Key Benefits of Enterprise Architecture
- Strategic Alignment - Ensures IT supports business objectives
- Cost Optimization - Reduces redundancy and improves efficiency
- Risk Management - Identifies and mitigates architectural risks
- Innovation Enablement - Provides foundation for digital transformation
- Compliance - Ensures adherence to regulations and standards
📋 Enterprise Architecture Frameworks
1. TOGAF (The Open Group Architecture Framework)
The most widely adopted EA framework, providing:
- ADM (Architecture Development Method) - Step-by-step approach to developing EA
- Architecture Repository - Structured approach to storing architectural artifacts
- Enterprise Continuum - Classification system for architectural assets
- Architecture Capability Framework - Guidelines for establishing EA practice
2. Zachman Framework
A comprehensive taxonomy for organizing architectural artifacts:
- Six Perspectives - Planner, Owner, Designer, Builder, Implementer, Worker
- Six Aspects - What, How, Where, Who, When, Why
- 36 Cells - Each intersection represents a unique architectural view
3. FEAF (Federal Enterprise Architecture Framework)
Government-focused framework emphasizing:
- Performance Reference Models
- Business Reference Models
- Service Component Reference Models
- Technical Reference Models
4. ArchiMate
Modeling language for enterprise architecture:
- Visual notation for architectural concepts
- Standardized way to describe architectures
- Integration with TOGAF methodology
