First, the concept of enterprise architecture
IT strategy can not match business strategy, IT and business processes out of touch, forward-looking and practical operation of conflict enterprise architecture, IT business innovation and new technologies how to lead, how the value of IT dominance, IT security system is not standardized low
Enterprise Architecture:
Master Plan - Planning function - partial engineering design
IT development - System Planning - System Solutions
Architecture: 3 strong and beautiful architecture principles and practical skills important
Enterprise Architecture definition of EA:
Enterprises - companies. Architecture - The basic structure of the system is comprised of multiple components have a certain relationship and the corresponding principles for the design and evolution in certain circumstances.
Business Architecture + IT infrastructure of enterprise IT planning and design
Content: Business Architecture. Business processes, organization, personnel
Technical Architecture: Application Architecture (B / s, c / s), data architecture (data information)
Value: Strategic landing, shared vision, a unified language, orderly evolution, build assets
Second, the history of enterprise architecture development
zachman1987
FEA (F) US Federal. System analysis of business processes, organization building, service capabilities, technology base 1999
TOGAF mainstream: 1995
DODAF：2003
Features: high-level approval is a prerequisite, core description is created and governance is the main line
1, TOGAF Introduction
The five key concern: whether the service-oriented architecture technology, openness, possibility of implementation, success stories, whether to support the SOI.
Components: Architecture Development Method (ADM), ADM guidance and technical architecture content framework, enterprises continuous series, reference models, architectures competency framework
ADM architecture development methodology: the preparatory stage - the vision of architecture, business architecture, information systems architecture, technical architecture, opportunities and solutions, migration planning, implementation, management, infrastructure change management
ADM and technical guidelines:
Architecture Content Framework:
Enterprise continuous series
Reference Model: TRM- Technical Reference Ⅲ-trm Integrated Information Infrastructure
2, architecture competency framework:
TOGAF enterprise cloud to guide planning
Business Architecture: based on business models and processes of cloud computing.
Technical infrastructure: cloud computing architecture to achieve complete decoupling enterprise business and IT resources.
Preliminary phase: the definition of enterprise-class cloud computing
Architecture Vision: Enterprise Cloud values and vision
Business architecture, information systems, technology: cloud-based service, information systems, technology architecture
3, opportunities and solutions: enterprise cloud deployment package
Migration Planning: Enterprise cloud roadmap
Implementation of governance: the deployment of enterprise cloud management
Architecture Change Management: Enterprise Cloud infrastructure change management
preparatory stage: corporate strategy, the necessity and feasibility of enterprise cloud planning and construction, research current situation and needs analysis, enterprise cloud construction mode, team building
Architecture vision: the vision of enterprise cloud, enterprise IT cloud of overall goals and objectives analysis, enterprise IT cloud of feasibility assessment
Business architecture stages: the development of cloud-based target business architecture, business architecture based on the current GAP analysis of the target business architecture, enterprise cloud roadmap identifying timely business architecture components
Information system architecture: the development of target-based data architecture and application architecture cloud computing, based on current GAP analysis architecture and the target architecture, enterprise cloud roadmap identifying data architecture and application architecture based on components
Technical architecture: the relationship between storage, computing, networking, software
Opportunities and Solutions: BCD merger gap analysis phase, generating major architectural landmarks, the drafting of enterprise cloud deployment and migration implementation plan outline
Migration Planning: Assess the business value of the migration package, evaluation and consultation needs and determine how to migrate the actual delivery of cloud to determine the final plan, the business value of the migration program, budget, program was the key to the relationship between man recognized
Implementation of governance: the enterprise cloud deployment, and monitoring the implementation of architectural constraints
Architecture change management: to ensure the maintenance and management of enterprise cloud architecture, routinely examine their ability to meet business needs infrastructure
