Why each option
On-premises infrastructure generally provides lower latency for physically adjacent systems compared to cloud infrastructure, which involves network transit to remote data centers.
Cloud infrastructure offers elastic scalability, allowing compute power to be increased on-demand much faster than procuring and deploying physical hardware in an on-premises environment.
On-premises infrastructure requires organizations to directly manage and pay for all power and cooling resources for their data centers, while cloud infrastructure shifts this burden to the cloud provider.
Cloud infrastructure allows for rapid provisioning of resources in minutes or hours, significantly faster than the procurement, installation, and configuration timelines typical for on-premises deployments.
For systems that are physically co-located with the on-premises infrastructure, the network path is minimal, leading to extremely low latency. This direct proximity can be critical for applications requiring ultra-low latency, whereas cloud services inherently involve network hops to geographically dispersed data centers, introducing more latency.
