BUSINESS PLUG-IN 4 IT ARCHITECTURES CIS 429: Business Information Systems
ENTERPRISE ARCHITECTURES Enterprise architecture The plans for how an organization will build, deploy, use, and share its data, processes, and IT assets Enterprise architect (EA) - a person who is… grounded in ____________ fluent in business a patient diplomat an important bridge between IT and the business
INFORMATION ARCHITECTURE: Backup and Recovery Backup An exact ________ of a system’s information Recovery The ability to get a system up and running Techniques used for backup and recovery Fault _________: The ability to respond gracefully to an unexpected hardware or software failure. Failover: A backup operation that automatically switches to a standby if the primary system fails.
INFORMATION ARCHITECTURE: Disaster Recovery Disaster recovery best practices: Mind the enterprise architectures Monitor the quality of computer _________ Make sure the networks can be restored quickly in the case of downtime Set up disaster recovery plans Provide adequate staff _________ so that operators are aware of any IT-related problems
INFORMATION ARCHITECTURE: Disaster Recovery Disaster recovery plan A detailed process for recovering information or an IT system in the event of a disaster such as a fire or flood Hot site—a separate fully-equipped facility Cold site—a separate facility without computer equipment Disaster recovery cost _______ Charts the cost to the organization of the unavailability of information and technology Charts the cost to the organization of recovering from a disaster over time
Disaster Recovery Cost Curve
INFORMATION ARCHITECTURE: Information Security A good information architecture includes a strong information security plan.. Managing user access Up-to-date _________ software and patches
INFRASTRUCTURE ARCHITECTURE Infrastructure architecture The hardware, software, and _________________ equipment that support the organization’s goals Five primary characteristics of a solid infrastructure architecture: 1. Flexibility—can handle all types of business changes 2. Scalability—adapting to increasing demands 3. Reliability—functioning properly 4. Availability—high degree of _________ 5. Performance—________ at performing processes
APPLICATION ARCHITECTURE Application architecture Determines how applications integrate and relate to each other Recent techniques:
Web Services Web service A standardized way of integrating Web-based applications using the XML, SOAP, WSDL and UDDI open standards over an Internet protocol backboneXMLSOAPWSDLUDDIopenstandardsInternetprotocolbackbone Events—Conditions that signal threats and opportunities, and alert those who can act on the information Service--_________ software products that appeal to a broad audience Interoperability The ability of software and hardware on different machines from different vendors to share data.
Open Systems Nonproprietary IT hardware and software made available by standards and procedures that Allow systems to seamlessly share information Capitalize on enterprise architectures Eliminate ___________ systems and promote competitive pricing For example Linux A freely-distributable open source operating system that runs on a number of hardware platforms. Open Office Open Office
