Week 6 – Enterprise Architectures

What is information architecture and what is information infrastructure and how do they differ and how do they relate to each other?


Information architecture identifies where and how essential information is maintained and secured. Back-ups and restore failures are very costly to an organisation. This is because some data cannot be re-created and the business intelligence lost from that data can be enormous.


Information infrastructure consists of the hardware, software and telecommunication tools that are combined to provide the underlying foundation to aid in achieving organisational goals.


These two infrastructures relate as they both provide methods for providing security and maintenance of information. they differ in the method they follow to obtain this maintenance and security. for example, information architecture uses functions such as backup and recovery while infrastructure uses hardware.

Describe how an organisation can implement solid information architecture?
 An organisation can implement a solid information architecture through backing up and recovery, disaster recovery and information security


A back up is an exact copy of a system's information while recovery allows someone to get a system up and running in the event of a system crash or failure.


Disaster recovery aims to recover information or an IT system in the event of a catastrophic disaster such as a fire or a flood.


Information security makes sure the right people have the right access to the right information. This is effective by managing user access and having an up to date antivirus software and patches. List and describe the five requirement characteristics of infrastructure architecture.

List and describe the five requirement characteristics of infrastructure architecture?


Flexibility: Flexibility is essential for a business in such a dynamic environment. It helps develop schools to be ready to meet those changes.


Scalability: is how well a system adapts to increasing demands. An organisation who grows too fast must be able to be ready to handle larger demands such as increased disk space, currencies etc.


Reliability: ensures all systems are functioning correctly and providing accurate information.


Availability: occurs when a system can be accessed by users. a system that is available at all time of the day is seen to be of high availability


Performance: measures how fast a system undergoes certain activities or transactions. Insufficient performance capacity can lead to devastating impacts on a business.

Describe the business value in deploying service oriented architecture.


Service oriented architecture is a business driven IT architectural approach that supports a business as linked repeatable tasks or services. they aid business innovation by making sure IT systems adapt fast, easily and economically to support the dynamic needs of the business.

What is an event?


An event is an occurrence in the system that tells itself that a certain thing is occurring.

What is a service?


A service is a business task that is a part of the business process


What emerging technologies can companies can use to increase performance and utilise their infrastructure more effectively?


Virtualisation: a framework for dividing the resources of a computer into multiple execution environments. It increases physical resources to maximize the investment in hardware. This way people, processes and technology work together more efficiently to meet increased service levels.


Grid computing: an aggregation of geographically dispersed computing, storage and network resources, coordinated to deliver improved performance, higher quality of service, better utilization and easier access to data.
