Optimizing Real-Time Data Synchronization for Hybrid Cloud/On-Premise Applications
// Download new cloud orders HTTPRequest("https://cloud.myapp.com/api/v1/pull?since=" + LastSyncDate) JsonArray = JSONParse(Request.Body) FOR EACH JsonElement OF JsonArray Local_CloudOrder.ID = JsonElement.ID IF HReadSeekFirst(Local_CloudOrder, ID, JsonElement.ID) = False THEN Local_CloudOrder = JsonElement HAdd(Local_CloudOrder) END END In hybrid sync, conflicts are inevitable. Do not use "Last write wins." windev magazine
This is a great request. is a powerful IDE (from PC Soft) that is popular in French-speaking markets (France, Belgium, Switzerland, Africa) and increasingly in enterprise RAD (Rapid Application Development) circles. This architecture respects the network boundaries: the cloud
This architecture respects the network boundaries: the cloud never touches your firewall, and the premise never blocks the user for network errors. windev magazine
HAdd(Cloud_Order)
The challenge is not building the apps; it is . You cannot expose your on-premise HFSQL directly to the internet, and batch imports/exports are too slow for real-time inventory. 2. The Architecture: The "Reversé" Proxy Pattern Instead of the cloud pulling data from the premise (which requires opening firewall ports), we will use the premise pushing data to the cloud via secure REST APIs. We will also use HFSQL Native Replication for the read-only data.
