What is the "Cloud" in cloud computing?• Refers to where applications are run

and stored.

Benefits of Cloud Computing Reduced Costs• Initial infrastructure setup• Infrastructure maintenance and upgrades

Reliability• Google Apps boasts a 99.9% uptime

Scalability• Virtually unlimited computing power and storage

  Security of the cloud• More dedicated resources 

Risks of Cloud Computing

No internet?• One big problem.

Outages• At the mercy of your cloud provider

Big Brother?• Cloud provider has access to personal information

Security• Limited to the security of your cloud provider

What is IaaS?• Service which delivers computer infrastructure• Typically consists of virtual platforms

Why use an IaaS provider?• Don't have to purchase expensive equipment • Don't have to deal with maintenance on equipment• Create customized instances of an OS• Scalability

Amazon Web Services

Amazon Elastic Compute Cloud (EC2)• provides scalable computing capacity in the cloud.• Pay for what you use• Start new server instances on-demand

 Can run instances of different OS's• RedHat Linux, Windows Server, openSuSE Linux, Fedora,

Debian, OpenSolaris, Cent OS, Gentoo Linux, and Oracle Linux.

Allows small businesses to inexpensively acquire the resources they need
