PRIVATE CLOUD
For this section we are going to let you see precisely what a Private Cloud is and the three models you can utilize.
The NIST (National Institute of Standards and Technology) definition lists five primary characteristics of cloud computing:
- On-demand self-service – a customer can easily manage their own services without the help of their IT department or a hosting provider;
- Broad network access – the cloud services are accessible via normal broadband networking technologies;
- Resource pooling – the services that are running in a DataCenter are using a shared infrastructure with multiple other customers;
- Rapid elasticity or expansion – the capacity of the cloud services can be easily adjusted to the demand. The services can be scaled up and down as demand changes;
- Measured service – the capacity of the cloud services are optimized for customer usage and its usage is reported on a regular basis.
Based on this criteria NIST also defines three service models of cloud computing.
