Frameworks
Frameworks provide a structured approach, methodologies, and guidelines for developing and managing an organization’s Enterprise Architecture. They address the “how” of architecting.
- TOGAF (The Open Group Architecture Framework)
- ADM (Architecture Development Method): The core of TOGAF, a cyclical process for EA. Phases include Preliminary, Architecture Vision, Business/Information Systems/Technology Architecture, Opportunities & Solutions, Migration Planning, Implementation Governance, Architecture Change Management.
- Content Framework: Defines types of architectural artifacts (deliverables, building blocks) created in the ADM.
- Enterprise Continuum: A repository model helping classify & organize architectural assets, aiding reuse and evolution over time.
- Zachman Framework
- Matrix Structure: 6 rows (“Perspectives” โ Planner, Owner, Designer, Builder, Subcontractor, Enterprise User) intersect with 6 columns (“Aspects” โ Data, Function, Network, People, Time, Motivation). Each cell of the matrix addresses specific questions to promote comprehensive architecture description.
- Focus: Not prescriptive about how to architect; it serves more as a checklist to assure complete EA thinking.
- FEAF (Federal Enterprise Architecture Framework)
- Reference Models: Provide common vocabulary and blueprints across federal agencies: Performance, Business, Service, Component, Technical, Data, Security Reference Models.
- Collaborative Planning Methodology: Helps agencies link mission objectives to IT investments.
- Specific to: US Government, and may be too cumbersome for private sector businesses.
Modeling Languages
Modeling languages offer a standardized visual vocabulary to represent and communicate complex architectural designs. These are the “tools” to translate your architectural thinking into clear models.
- ArchiMate
- Core Layers: Business, Application, Technology, linked by Motivation and Implementation & Migration elements.
- Viewpoints: Create tailored views of the architecture (e.g., a Strategy Viewpoint, a layered Application Cooperation Viewpoint, etc.).
- Visual Notation: Clear icons and notations to represent elements like actors, services, processes, data objects, applications, servers, etc.
- BPMN (Business Process Model and Notation)
- Flow Objects: Activities (tasks), Events (something that happens), Gateways (decision points).
- Connecting Objects: Flows depict process sequences, message/data flows link elements.
- Swimlanes: Organize activity by roles or organizational units.
- UML (Unified Modeling Language)
- Vast Set of Diagram Types: Use Case, Class, Sequence, Activity, State Machines, Deployment, etc.
- Software-Centric: Best for detailed representations of systems and their interactions.
- Complementary: UML adds granularity within an established EA metamodel like ArchiMate.
Domain-Specific Standards
Standards focused on a broad functional area applicable across businesses (e.g., IT service management, cybersecurity). They often involve best practices and governance guidelines.
- ITIL (Information Technology Infrastructure Library)
- Focus: Not strictly architectural, but highly influential. ITIL defines a service lifecycle (Strategy, Design, Transition, Operation, Continual Improvement) with detailed best practices for processes like Incident Management, Change Management, Problem Management, etc.
- Relation to EA: EA ensures that the overall architecture design supports smooth IT service delivery, making alignment with ITIL processes key.
- COBIT (Control Objectives for Information and Related Technologies)
- Focus: Governance and management of enterprise IT. COBIT’s goals and processes ensure IT creates business value, manages risks, and optimizes resources.
- Relation to EA: EA serves as an enabler to fulfill COBIT objectives, especially as the business and technology landscapes become increasingly intertwined.
- NIST Cybersecurity Framework
- Focus: Holistic approach to cybersecurity risk management. It comprises functions: Identify, Protect, Detect, Respond, Recover.
- Relation to EA: Designing a secure enterprise architecture goes hand-in-hand with this framework; elements like network design, software selection, and access control all need to consider relevant NIST criteria.
Industry-Specific Standards
Standards addressing the unique processes, regulations, and technological needs of a particular industry (e.g., telecommunications, health).
- TM Forum (Telecommunications Management Forum)
- Industry Focus: Telecom providers and technology suppliers to this sector.
- Standardization Areas: TM Forum offers open APIs, best practices, and reference models covering areas like business process (eTOM), data (SID), and integration architecture.
- Relevance: EA in the telecom space needs strong awareness of these standards.
- FIANET (Insurance)
- Industry Focus: Focused on the insurance industry
- Scope: A comprehensive architecture foundation spanning business processes, applications, technology infrastructure relevant to insurance companies.
- Relevance: Promotes standardization and consistency within the insurance field.
- HIPAA (Health Insurance Portability and Accountability Act)
- Industry Focus: US-specific healthcare regulation and its supporting technical standards.
- Key Mandates: HIPAA dictates strict controls around patient data privacy and security, as well as the standardization of electronic health transactions.
- Relevance: EA in healthcare must conform to HIPAA; the architecture impacts data handling, access, systems design, and compliance measures.
Important Considerations
- Not One-Size-Fits-All: Domain/industry standards vary greatly in scope and detail. Some provide high-level guidelines; others are deep, prescriptive blueprints.
- Compliance: Specific standards might be mandatory due to legal regulations (like HIPAA) or industry agreements.
- Evolution: These standards, especially in technology-driven sectors, get updated frequently to keep pace with innovation and security landscapes.
What about Cloud?
The Azure Well-Architected Framework, along with the AWS Well-Architected Framework and Google Cloud’s Well-Architected Framework, are cloud-specific best practices and guidance for designing robust and efficient cloud-based systems. Here’s how they fit in:
Core Pillars
These cloud frameworks share similar foundational principles (though their exact naming may differ slightly):
- Cost Optimization: Strategies to design and operate cost-effective cloud solutions, maximizing the value derived from your cloud expenditure.
- Operational Excellence: Processes and best practices to achieve smooth operations, reliable monitoring, and automation within your cloud environments.
- Performance Efficiency: Techniques to scale resources dynamically, optimize application performance, and ensure a seamless user experience.
- Reliability: Methods to design resilient architectures; this addresses fault tolerance, self-healing mechanisms, and disaster recovery preparedness.
- Security: Guidelines for protecting data, assets, and infrastructure in the cloud; includes concepts like secure network design, identity management, and data encryption.
Where They Fit in Enterprise Architecture
Cloud-specific frameworks play a complementary role within a broader Enterprise Architecture context:
- Alignment: Your overarching EA, as guided by a framework like TOGAF, will establish enterprise-wide principles and strategic goals. The cloud framework ensures cloud applications and systems adhere to these broader directives.
- Technical Specificity: Azure, AWS, and GCP frameworks delve into the technical nuances of their respective platforms. They offer insights on service selection, cloud-native patterns, and configuration guidance far more granular than an enterprise-wide standard.
- Tools: Cloud providers offer assessment tools and checklists aligned with their well-architected frameworks (example: Azure Well-Architected Review). This aids in gauging the compliance of your cloud systems against their recommendations.
Choosing the Right Framework
- Primary Cloud Provider: If you predominantly work in Azure, the Azure Well-Architected Framework offers the most seamless alignment. The same logic applies to AWS or GCP.
- Hybrid or Multi-Cloud: In complex scenarios where you use multiple cloud services, you might want to utilize concepts from various frameworks. Your enterprise-wide EA should guide decisions while balancing platform-specific needs.
