|
Term
|
Definition
| where information is managed in a centralized architecture |
|
|
Term
| decentralized architecture |
|
Definition
| the hardware, software, networking, and data are arranged in a way that distributes the processing and functionality between multiple small computer, servers, and devices and they rely heavily on a network to connect them together- general on multiple servers and not located in the same location |
|
|
Term
| service-oriented architecture (SOA) |
|
Definition
| larger software programs are broken down into services connected to each other, usually avaiable through multiple vendors An example of a service might be an online employment form that, when completed, generates a file with the data for use in another service |
|
|
Term
| Decentralized architectures are good for what? |
|
Definition
| good for adding on more space or capacity |
|
|
Term
| Centralized architectures are good for |
|
Definition
| being easier to manage because all functionality is centralized in the main computer. |
|
|
Term
| Why are service oriented architecture being popular |
|
Definition
| because the design enables large units of functionality to be built almost entirely from existing software service components. It is useful for building applications quickly because it offers manager a modular and compentized design. |
|
|
Term
|
Definition
| allows networked computer to share resources without a central server playing a dominate role |
|
|
Term

|
|
Term
|
Definition
| are architectures in which significant hardware, software, and possibly even data elements reside on the internet. Used well with Capacity on Demand. Use when building App's or business is new and lots of App's to be built |
|
|
Term
|
Definition
| demand for availability additions of processing capability for a fee |
|
|
Term
|
Definition
| people wanting to bring their own decices to work and have work applications run on them |
|
|
Term
|
Definition
| the drive to port applications to personal devices and the ensuing issues to make them work is referred to as consumerization fo IT. This is about making applications run on you phone or Ipad not just work applications |
|
|
Term
| the 4 components for an enterprise architecture are? |
|
Definition
core business processes
shared data
linking and automation technologies
customer groups |
|
|
Term
|
Definition
| includes a methodology and a set of resources for developing an enterprise architecture. IT is based on the idea of an open architecture, an architecture whose specification are public (as compared to a proprietary architecture, where specification are not made public |
|
|
Term
|
Definition
| determines architectural requirements by providing a broad view that helps guide the analysis of the detailed view. It used the conceptual business model, the logical system model, and the physical technical model |
|
|
Term
| enterprise architecture (EA) |
|
Definition
| is the term for organizing logic for the entire organization, often specifying how information technologies will support business processes. It differs from an IT architecture in its level of analysis. IT identifies the core processes of the company and how they will work together, how the IT systems will support the processes, the standard technical capability and activities for all parts of the enterprise, and guidelines for making choices. It's more than just linking the buiness process to the IS. It strats with organizational vision and strategy. It persues consitiancy and standarizatoin |

| means one where software replaced hardware in a way that a "virtual machine" or a "virtual desktop system" was accessible to provide computing power. |
|
|
Term
|
Definition
| it is based on the concept of a virtual infrastructure. Entire computing infrastructure are available "in the cloud" |
|
|
Term
|
Definition
| purchasing entire capabilities on an as- needed basis. |
|
|
Term
|
Definition
| refers to how well an infrastructure component can adapt to increase or in some cases decreased demand. This is great bc a firm won't out grow its infrastructure |
|
|
Term
|
Definition
| hardware and software that uses a common standard, as opposed to a proprietary approach, are easier to plug into an existing or future infrastructure or architecture because interfaces often accompany the standard. EX: using Microsoft Office |
