2 ADD NAME (View > Master > Slide master)

Agenda● Compare services that the two platforms provide● Compare business characteristics of AWS & OpenStack● How to choose a platform?● How to use both environments?

Product demonstrations!● This session focuses on business problems, strategies and solutions

and is not a technical deep dive.

What is OpenStack● A cloud operating system that controls large pools of compute,

storage, and networking resources● Managed through a dashboard or command line ● Empowers users to self provision using a GUI or CLI

4 ADD NAME (View > Master > Slide master)

What is AWS● Provides a way to access servers, storage, databases and a

broad set of application services over the Internet. ● Amazon Web Services own and maintain the network-connected

hardware required for these application services,● You provision and use what you need
