• To Explain how to get the “Cable” into the “Cloud”
© Simplified Innovations Inc© Simplified Innovations Inc
• Many definitions!
• Model of enabling convenient, on-demand network access to shared computing resources (e.g., networks, servers, storage, applications, and services) that can be released with minimal service provider interaction.
• It is simply a classification, an add-on to:
• LAN, WAN, Grid, Etc…
• The “Cloud” is a metaphor for the Internet
• Data and applications now live in the internet

• A service used for software programmers to develop web applications
• Software Platform is provided and managed
• Programmers plugin their code and focus on their application rather than the challenges associated with managing the software components:
• Servers
• Databases
• Bandwidth
• Etc
Characteristics of PaaS
