Characteristics of Cloud Computing
There are four key characteristics of cloud computing. They are shown in the following ste
Deployment Models:
- Hybrid Clouds
- Private Cloud
- Community Cloud
- Public Cloud
Service Models:
- Software as a Service (SaaS)
- Platform as a Service (Paas)
- Infrastructure as a Service (Iaas)
Essential Characteristics On Demand Self-Services
Broad Network Access -> Repaid Elasticity
Resource Pooling -> Measured Service
Common Characteristics of Cloud Computing:
- Massive Scale
- Homogeneity
- Virtualization
- Low Cost Software
- Resilient Computing
- Geographic Distribution
- Service Orientation
- Advanced Security
ON DEMAND SELF-SERVICE
Cloud Computing allows the users to use web services and resources on demand. One can logon to a website at any time and use them.
BROAD NETWORK ACCESS
Since Cloud Computing is completely web based, it can be accessed from anywhere and at any time
RESOURCE POOLING
Cloud Computing allows multiple tenants to share a pool of resources. One can share single physical instance of hardware, database and basic infrastructure.
RAPID ELASTICITY OF CLOUD COMPUTING
It is very easy to scale up or down the resources at any time.
Resources used by the customers or currently assigned to customers are automatically monitored and resources. It make it possible
