1. A method for service level agreement enforcement, implemented by a processor of a computing system, the method comprising: intercepting a request for a current runtime environment by a segmentation module of the computing system; extracting request data from the request by the segmentation module; passing the request data from the segmentation module to a risk assessment component of the computing system, wherein the risk assessment component performs a risk assessment of servicing the request in a runtime environment by: (i) determining a request impact on runtime environment resources from a request history profile matching the request data; and (ii) determining existence of a risk to a service level agreement associated with the request or any other request currently executing if the request is serviced in the current runtime environment, based on the request impact and a current state of the current runtime environment; and receiving the risk assessment from the risk assessment component by the segmentation module; wherein when the risk assessment indicates existence of the risk to the service level agreement associated with the request or any of the other request currently executing, the request is passed to an isolated runtime environment by the segmentation module; wherein when the risk assessment does not indicate existence of any risk to the service level agreement associated with the request or any of the other request currently executing, the request is passed to the current runtime environment by the segmentation module.
