AWS IoT SiteWise Edge supports new data storage and upload prioritization strategies for intermittent cloud connectivity

AWS IoT SiteWise Edge allows you to define edge data storage strategies to prevent loss of operational data while disconnected (up to 30 days) as well as choosing a data upload strategy to the cloud upon re-connection. Application data uploaded to the cloud is often time critical, where values beyond a certain age may not be relevant for short term actions. Conversely, older historical data can be important in diagnosing long term trends and diving deep into equipment operational performance for non-time critical applications.
