Questions and Answers
cloud computing definition Correct Ans-ICT architecture in which users access software
applications and information systems remotely over the internet, rather than locally on an
individual PC or from servers in the organization's data center
drawback is that you must have an extremely reliable internet connection
3 most common styles:
1. Infrastructure as a service
2. Platform as a service
3. Software as a service
Infrastructure as a Service (IaaS) Correct Ans-Cloud hosting service provides computer
resources such as virtual servers, storage, and processing power, allowing clients to configure
the resources as they choose
Platform as a Service (PaaS) Correct Ans-cloud hosting service provides computer resources
and also operating systems, application development environments, and often a database
management system
---------------------- Correct Ans-----------------------
a small business Correct Ans-not built on a new idea
established business processes, supply chain networks and regulatory frameworks
still 50% failure rate
,a start up Correct Ans-starts with something new, an acceptable definition of new is a
process or product that is 10x better
they often start with a small market segment that they can dominate
have to develop business processes, supply chain networks and regulatory frameworks
startups need to grow fast
startups are often first movers
first movers Correct Ans-advantages
-- first to market
-- can capture market share much more easily without having to worry about rivals
-- initial press
disadvantages
-- have to be the "explainer"
-- have to work out all the R&D issues
-- are "stuck" with your product design for some period
first to sell the product
47% failure rate
fast followers Correct Ans-advantages
,-- more likely to win
-- don't need to be the first mover to innovate
-- know what the market is for the products
-- use your existing place in the market / existing resources to promote your new product
entered early but not first
8% failure rate
first mover vs fast follower Correct Ans-hydrox = FM
oreo = FF
tide = FM
all pacs = FF
friendster = FM

chrome = FF
value chain model Correct Ans-support activities
-- admin and management

RAID 1: disk mirroring Correct Ans-copies of data on two separate disks
gives good error recover if some data is lost, get it from the other source
expensive: requires twice as many disks
write performance can be slow; have to write data in two different spots
read performance is enhanced can read data from file in parallel
RAID 5: block level striping with distributed parity Correct Ans-parity is a highly compressed
version of its original file
parity information is distributed among the drives
it requires all drives but one be present to operate
upon failure of a single drive, subsequent reads can be calculated from the distributed parity
such that no data is lost
