what is cloud computing?
Cloud Computing is a model that allows a pool of configurable computing resources that can be easily accessed with minimal management effort or service provider interaction. It can reduced IT cost, add business agility support, makes scaling more flexible, provide high availability, and consumes less energy. It also has 3 different models which is Infrastrucure-as-a-service (IaaS), Platform-as-a-Service (PaaS), and Software-as-a-Service (SaaS). Infrastrucure-as-a-service (IaaS) provides consumter to hire infrastructure components such as servers, storage, and network and example of this is Amazon Elastic Compute Cloud. ), Platform-as-a-Service (PaaS) provides consumer to reply consumer-created or acquired applications on the Cloud provider's infrastructure. An example of this is the Google App Engine which allows consumers to deploy or create their own applications. Software-as-a-Service (SaaS) provides the consumer to use provider's applications running in a Cloud infrastructure. An example of this is Salesforce.com where consumers can access CRM applications from anywhere, anytime.
