FinOps
FinOps is a practice that aims to optimize the costs associated with the use of cloud services by aligning expenses with usage. In other words, by aligning resource consumption with the actual activity of the services.
This approach is dynamic; it is opposed to the fairly widespread practice that relies on a fixed allocation of resources. This latter approach provides readability of costs but does not allow resources to be adjusted upwards or downwards according to peaks or troughs in activity.
HyperScaler
A Hyperscaler provides cloud services on a large, often global, scale. It has large computing and storage capacities. It can absorb the simultaneous load of many users by relying on a large network of data centers . Hyperscalers also offer a marketplace of off-the-shelf digital services. Their model is based on managed services.
The largest are American and are called AWS, Google Cloud Platform (GCP) or Azure.
Hyperscalers are CSPs but not all CSPs are hyperscalers. The hyperscaler has at least a continental or even global dimension, while some CSPs have a national or even regional scope.
