22
Q

What is cloud computing

A

provides access to shared resources over
the internet
Allows company to minimize computer resources kept on hand

23
Q

What are the three cloud deployment models

A

Private (customized, high security)
Public ( readily available , lower cost
Hybrid ( moderate cost and security ,increase flexibility )

24
Q

What are the cloud computing services models

A

Software as service (SAAS)
Platform as service ( PAAS)
Infrastructure as a service ( IAA)

25
Q

Software as services does

A

Utilizes the internet to provide customers with
applications that are managed by the third-party
provider. (ex: google drive, microsoft office)

26
Q

Platform as service does

A

Provides customers a platform for software
development that is delivered remotely. ex: google app engine , Openshift

27
Q

Infrastructure as service does

A

Provides customers with fully self-service
computers, networking, storage, and operating
systems through virtualized environments. Ex : amazon wen service, microsoft azure

28
Q

What are the risk as a SaaS cloud provider

A

Reliability, privacy and security

29
Q

A

is when the acquiring company moves the acquired systems, placing it in the data center maintaining the existing systems as they are and the users have access to all the systems at the same time

35
Q

Explain immediate integration

A

that when multiples systems requires converting existing data in the system to be retired and migrating it into the new systems and the original systems are then eliminated

36
Q

What us a centralized systems

A

connect all users to one central location built around a server that all authorized users can acess

Q

What are the advantages of centralized systems

A

easier to set up
Data is easy to access
Consistency in processing
Cost is lower

38
Q

What are the disadvantage of centralized systems

A

risk of disruption is greater
may experience transaction bottlenecks if traffic is high
Other location may experience lag time

39
Q

What is decentralized systems

A

utilizes multiples locations that each maintain a copy of the data needed for its connected systems. Not all users are connected to all acess points

40
Q

What are the advantage of decentralized systems

A

processing power and data storage needed is reduced
higher responsiveness
Processing bottlenecks are reduced
if one systems fail there are others

41
Q

What are the disadvantage of decentralized systems

A

increase of security risk
Cost of installing is higher

42
Q

What is distributed system

A

all the users and systems are directly connected to one another across the network, the processing and database are distributed among several business locations
