In general, migrating to the cloud saves energy and reduces carbon emissions compared to running workloads on-prem or in a private data center.
But that’s not universally the case. Sometimes, your existing workload deployment strategy may be more sustainable than what you could achieve using the cloud.
Determining the difference – in other words, figuring out whether cloud migration will actually result in greater sustainability – boils down to assessing the sustainability of your current workloads and comparing that with the sustainability of the cloud.
