2. What services can be offered
via „cloud“?
● Only IT services (hardware, software)
● Three main categories:
● Infrastructure as a Service (IaaS)
● Platform as a Service (PaaS)
● Software as a Service (SaaS)

3. Infrastructure as a service (IaaS)
● Provides the computing infrastructure, physical or virtual
machines (servers) and other HW resources
● Examples: Amazon EC2, Windows Azure, Rackspace
● The lowest level of „XaaS“
● You can use IaaS e.g. to run your own virtual server

4. Platform as a service (PaaS)
● Provides computing platforms which typically includes
operating system, programming language execution
environment, database, web server etc.
● Examples: AWS Elastic Beanstalk, Heroku, Force.com,
Google App Engine
● The middle level of „XaaS“
● You can use PaaS e.g. to build and manage your own
rich app more comfortably as in IaaS

5. Software as a service (SaaS)
● Provides an access to a ready-to-use software.
● You don't have to worry about the installation, setup and
running of the application.
● The only required software on your PC is the internet
browser
● Examples: Google Apps, Microsoft Office 365, ADIOS
Business Suite
● The top level of „XaaS“
● You can use SaaS e.g. to manage your company or the
project
