SLA manager (SLA Lite)
The SLALite is an automatic tool that manages SLAs in both Edge and Fog environments. The tool is in charge of creating the digital contracts for the micro services, capturing the availability metric (% cloud/edge nodes and components availability) through the Monitoring System and assessing the contract fulfilment. The result of the assessment is sent to FogAltas to proceed with the orchestration of the due services.
An important feature that Atos has developed in the context of DECENTER is the ability for the tool to interact with blockchain technologies. This will enable improvements in trustworthiness in rich distributed Edge, Fog and Cloud systems.
