1. CLOUD COMPUTING RICH SANGPROM

2. What is cloud computing? “Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.” - NIST Definition

3. Characteristics On-demand self-service Broad network access Resource pooling Rapid elasticity Measured service

4. Service Models Software as a Service (SaaS) Platform as a Service (PaaS) Infrastructure as a Service (IaaS)

5. Software as a Service (SaaS) Gives the user the ability to utilize applications hosted on a cloud infrastructure Borrowing/renting software online Google Documents

6. Platform as a Service (PaaS) The user is able to deploy custom applications and services User has control over deployed applications Similar to an app store

7. Infrastructure as a Service (IaaS) Technology from a cloud provider is outsourced to a user/client as a service User has control over operating systems, storage, and deployed applications Pay per use basis

9. Deployment Models Private Cloud - Single organization Community Cloud - Multiple organizations Public Cloud - General public Hybrid Cloud - Multiple cloud infrastructures - (ex. private cloud + oublic cloud)
