The main differences between on-premise and public cloud deployments are as follows:
Deployment site: On-premise deployment is to deploy the software system on the user's own hardware devices and servers, which are managed and maintained by the user. Public cloud deployment, on the other hand, deploys software systems in the data center of a cloud service provider, which is managed and maintained by the cloud service provider.
Data security: On-premise data storage and transmission processes are completely controlled by the user, so they can provide higher data security. However, the data storage and transmission process of public cloud deployment is handled by the cloud service provider, so the data security is relatively low.
Flexibility: On-premise deployments typically offer greater flexibility and customizability, allowing users to customize configurations to meet specific business needs based on their needs, and can be scaled and upgraded according to actual conditions. Public cloud deployments, on the other hand, are less flexible because cloud service providers typically provide standardized services that users need to configure and use based on the services provided by the provider.
Cost: On-premise deployment requires users to bear the hardware, software, and implementation costs, as well as post-maintenance costs, which are relatively costly. Public cloud deployments, on the other hand, usually require users to pay for the purchase of services, and although the upfront investment is low, the long-term use cost may be high.
To sum up, the main differences between on-premise and public cloud deployments are in terms of deployment location, data security, flexibility, and cost. Users can choose the deployment method that suits them according to their own needs and actual conditions.
