Q

What is Cloud Bursting?

A

Offloading resources into the cloud platform in times of heavy demand

17
Q

What are the drawbacks of a Hybrid Cloud?

A

Cost
Offloading of mission critical content (only as reliable as the CSP)
Compatibility

18
Q

What are the 3 types of Cloud Service Models?

A

IaaS (infrastructure), PaaS (platform), SaaS (software)

19
Q

What does the Cloud model focus on?

A 
Scale out (not up), distributed, stateless and elastic/flexible resource allocation.
Shifting capital to operational expenditures.
20
Q

How to design a Cloud

A

Planning, big to little

21
Q

Clouds are the be-all end-all of a business plan (T/F)

A

False

22
Q

Work little to big when designing a Cloud (T/F)

A

False

23
Q

A cloud solution should not be heterogeneous (T/F)

A

True

24
Q

You should prioritize a design in accordance with the business drivers (T/F)

A

True

25
Q

What are some things to consider when designing a Cloud?

A 
The challenge
Your applications/data
Costs associated
Proper research into CSPs
Data governance and security
The overall strategy
26
Q

What is On-Demand Self-Service?

A

Consumers can provision computing capabilities as needed automatically without requiring human interaction with each service provider

27
Q

What is Broad Network Access?

A

Consumers access cloud services on any client/end point device from anywhere over a network

28
Q

What is Resource Pooling?

A

The computing resources are pooled to serve multiple consumers using a multi-tenant model with resources dynamically assigned/reassigned according to demand

29
Q

What is Rapid Elasticity?

A

The ability to quickly request, receive, and release as many resources as needed. Gives a sense of unlimited resources that can be provisioned at any time

30
Q

What is Measured Service?

A

Automatic control and optimized resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service

31
Q

What is an SLA?

A

An agreement between an IT service provider and a customer which describes the service, documents service level targets, and specifies the responsibilities of the provider and customer

32
Q

What to look for in an SLA?

A

Formal and legally binding
Quantitative not Qualitative
Will cover key aspects of your cloud service

33
Q

Monolithic designs are flexible and implement increased capacity on demand (T/F)

A

False

34
Q

Monolithic design methodologies are an integral part of cloud design (T/F)

A

False

35
Q

What does quick resource provisioning allow?

A

On-demand burst and dynamic resources

36
Q

What is Resource pooling?

A

A process where resources are shared and assigned/reassigned dynamically amongst the tenants

37
Q

What does broad network access mean?

A

Resources are accessible anywhere, anytime over the internet
