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)

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

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

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.
