CLOUD COMPUTINGRICH SANGPROM
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
Characteristics• On-demand self-service• Broad network access• Resource pooling• Rapid elasticity• Measured service
Service Models• Software as a Service (SaaS)• Platform as a Service (PaaS)• Infrastructure as a Service (IaaS)
Software as a Service (SaaS)• Gives the user the ability to utilize
applications hosted on a cloud infrastructure• Borrowing/renting software online• Google Documents
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
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
Deployment Models• Private Cloud
- Single organization
• Community Cloud - Multiple organizations
• Public Cloud - General public
• Hybrid Cloud - Multiple cloud infrastructures - (ex. private cloud + oublic cloud)
Several Significant Companies in Cloud Computing
