Architecture & Infrastructure Define: client/server, server, thick client, thin client, mainframe, legacy system, peer-to-peer Distinguish architecture from infrastructure Discuss the relationship between strategy, business requirements, architecture, and infrastructure Discuss the applicability of evaluation criteria to architecture and infrastructure Analyze infrastructure and architecture needs across hardware, software, data and networks Describe the purpose and steps in Business Continuity Planning Define and describe SOA 1

Who needs IT Architecture and Infrastructure?

Strategy, Requirements, Architecture & Infrastructure Business Requirements Architecture Infrastructure

Information Architecture High level map of info requirements; blueprint Centralized: data communications Decentralized: focus on organizational function Translates strategy into infrastructure Hard to define: needs change 3

Information Infrastructure Physical facilities, services, management supporting computing resources hardware Software networks & communications data personnel 2

Managerial Considerations Existing Architecture Current & Future Requirements Financial Issues Technical Issues

Evaluation Criteria: Applicability

Evaluation Criteria: Applicability (cont)

Meta Group Guidelines for Adaptable IT A&I Plan modular (independent and loosely coupled) vs. monolithic Have clear boundaries between infrastructure components With network architecture, provide access to all users when it makes sense to do so

Architecture Definitions Mainframe- Computing environment in which a large central computer handles all system functionality Peer-to-peer- Architecture that allows networked computers to share resources without a central server playing a dominant role Client/Server Architecture Wireless (Mobile)- Computing environment maintaining a data connection from a remote network using a wireless technology 5

Architecture Definitions - Client/server Client - PC or workstation attached to a network which is used to access shared network resources Server - machine that provides clients with services (i.e., sharing databases, software) Thick client - full function stand-alone computer that is used either exclusively or occasionally as a client in a client/server architecture Thin client - computer hardware designed to be used only as a client in a client/server architecture (Network PCs) 5

Service Oriented Architecture (SOA) SOA - architectural design pattern that concerns itself with defining loosely-coupled relationships between producers and consumers. Guiding Principles Reuse, granularity, modularity, and interoperability Compliance to standards (both common and industry-specific) Services identification and categorization, provisioning and delivery, and monitoring and tracking
