AYB114 Lecture Notes - Lecture 8: Data Loss, Cloud Computing Security, Data Center
Week 8 – cloud computing
What is cloud computing?
•In simple terms, cloud computing means storing and accessing data and programs
over the Internet instead of from your computer’s hard drive
•“Cloud computing refers to both the applications delivered as services over the
Internet and the hardware and systems software in the data centres that provide
those services.” – from A View of Cloud Computer (refer to readings list)
Software as a service
•Issues
•It may not easily integrated into software already being used internally by the
business
•It can improve security - offsite data backup, service providers will usually invest
heavily in security which an individual business cannot do
•Reputable service provider – do not want the provider going out of business
•Monthly fees but are there any hidden costs
Platform as a service
•PaaS
•Provides a platform and environment to allow developers to build applications and
services over the internet
•Hosted in the cloud and accessed by users via their web browser
•Benefits include:
•Not having to invest in actual infrastructure and able to “rent” virtual
infrastructure
•With some PaaS offerings, you do not need development skills to develop
applications (eg. WordPress)
•Flexibility – users can pick and choose what features they want
•Can have a team around the world work on an application build
•Security – data security, backup and recovery
Infrastructure as a service
•IaaS

In simple terms, cloud computing means storing and accessing data and programs over the internet instead of from your computer"s hard drive. Cloud computing refers to both the applications delivered as services over the. Internet and the hardware and systems software in the data centres that provide those services. from a view of cloud computer (refer to readings list) It may not easily integrated into software already being used internally by the business. It can improve security - offsite data backup, service providers will usually invest heavily in security which an individual business cannot do. Reputable service provider do not want the provider going out of business: monthly fees but are there any hidden costs.
