Hot sites

Back 13

a separate and fully equipped facility where the company can move immediately

Back 14

a separate facility that does not have any computer equipment, but is a place where employees can move to after a disaster.

Front 15

Business continuity planning (BCP)

Back 15

is a plan for how an organization will recover and restore partially or completely interrupted critical functions within a predetermined time after a disaster or extended disruption.

Front 16

Good information architectures include:

Back 16

A strong information security plan,
Managing user access
up-to-date antivirus software and patches

Front 17

Infrastructure architecture

Back 17

includes the hardware, software, and equipment that, when combined, provides the underlying foundation to support the organizations goals.

Front 18

What are the 5 primary characteristics of a solid infrastructure architecture?

Back 18

1) Flexibility
2)Scalability
3)Reliability
4)Availability
5) Performance

Front 19

Flexibility

Back 19

organizations must watch todays business, as well as tomorrows when designing and building systems
-systems must be flexible enough to meet all types of business changes.

Front 20

Scalability

Back 20

refers to how well a system can adapt to increase demands

Front 21

Capacity Planning

Back 21

determines the future IT infrastructure requirements for equipment and additional network capacity
-performing a capacity plan is one way to ensure the IT infrastructure in scalable

Front 22

Reliability

Back 22

ensures all systems are functioning correctly and providing accurate information.
-Reliability is another term for accuracy when discussing the correctness of systems within the context of efficiency IT metrics.

Front 23

High Availability

Back 23

refers to a system or component that is continuously operational for a desirably long length of time.

Front 24

Performance

Back 24

measures how quickly a system performs a certain process or transaction(in terms of efficiency IT metrics of both speed and throughput)

Front 25

Application architecture

Back 25

determines how applications integrate and relate to each other.
-With new architectures, IT can build new business capabilities faster, cheaper, and in a vocabulary the business can understand.

Front 26

Web service

Back 26

contains a repertoire of web-based data and procedural resources that use shared protocols and standards permitting different applications to share data and services.

Front 27

Interoperability

Back 27

the capability of two or more computer systems to share data and resources, even though they are made by different manufacturers.

Front 28

What are the two primary parts of web services?

Back 28

Event: detect threats and opportunities and alert those who can act on the information
Service: more like software products than they are coding projects; need to be reusable if they are going to have an impact on productivity.

Front 29

Open system

Back 29

a broad, general term that describes non proprietary IT hardware and software made available by the standards and procedures by which their products work, making it easier to integrate them.

Front 30

Open source

Back 30

refers to any program whose source code is made available for use or modification as users or other developers see fit.

Front 31

What are 3 architecture trends that are quickly becoming requirements for all businesses?

Back 31

1) Service Oriented Architecture
2)Virtualization
3) Grid computing

Front 32

Service oriented architecture

Back 32

is a business driven IT architectural approach that supports integrating a business as linked, repeatable tasks or services.

Front 33

What are the key technical concepts of SOA?

Back 33

services
interoperability
loose coupling

Front 34

(A SOA) service

Back 34

can be a business task, such as checking a potential customers credit rating only opening a new account.
-Services are like software products
Service is what SOA begins with

Front 35

Interoperability

Back 35

is the capability of two or more computer systems to share data and resources, even though that are made by different manufacturers

Front 36

Extensible Markup Language

Back 36

(XML) a markup language for documents containing structured information.

Front 37

Loose coupling

Back 37

is the capability of services to be joined together on demand to create composite services, or disassembled just as easily into their functional components.
-Loose coupling is a way of ensuring that the technical details are decoupled from the service

Front 38

Virtualization

Back 38

is the framework of dividing the resource of a computer into multiple execution environments
-It is a way of increasing physical resources to maximize the investment in hardware.

Front 39

System virtualization

Back 39

is the ability to present the resources of a single computer as if it is a collection of separate computers ("virtual machines")
-each with its own virtual CPUs, network interface, storage and operating system

Front 40

What are some trends that have moved virtualization into the spotlight?

Back 40

Hardware being underutilized
Data centers running out of space
increased energy costs
System administration costs mounting

Front 41

Additional virtualization benefits are?

Back 41

Rapid application deployment
Dynamic load balancing
Streamline disaster recovery

Front 42

Grid Computing

Back 42

is 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

Front 43

Grid computing Business Benefits

Back 43

-Improving productivity and collaboration of virtual organizations and respective computing and data resources.
-Allowing widely dispersed departments and businesses to create virtual organizations to share data and resources
-Building robust and infinitely flexible and resilient operational architectures.
-Providing instantaneous access to massive computing and data resources
-Leveraging existing capital investments, which in turn help to ensure optimal utilization and cost of computing capabilities.
