A side-by-side extension is best suited for an application that requires: * Real-time tracking of deliveries. * Optimization algorithms for delivery routes. * High scalability and minimal maintenance downtime. By developing this extension in SAP BTP, it can run independently of the core ERP system, allowing for scaling and agility, which is essential for line-of-business-managed solutions. Side-by-side extensions leverage cloud services and ensure that maintenance or updates to the extension do not disrupt the core system.
