Cloud is a dynamic environment that can serve different types of requests using / sharing the same resources, seamlessly. The resources are shared by re-purposing, thus increasing the efficiency of the infrastructure
Cloud can be implemented by
- having an application that serves different types of requests.
- Quickly, re purposing the infrastructure to server different type of request.
Application based cloud: An application can be controlled by configuration parameters. By changing the parameters, the application serves different requests / purpose. This is challenging as older applications were not written keeping Cloud in mind. Too many parameters can complicate the application too.
Re-purposing the infrastructure: This requires automating the provisioning process like imaging the servers, application deployment, configuring DNS, traffic management etc. This is easier to implement as this is just automating the manual steps.
