The Future of ERP Integrations: Cloud-Native vs. On-Premise Strategies

Aim: This study aimed to conduct a comparative analysis of cloud-native, on-premise, and hybrid ERP integration models to assess their efficiency, reliability, and total cost of ownership. In turn, the market for ERP software is expected to increase to approximately USD 81.15 billion by 2024, shifting towards cloud-native and on-premise integration strategies. Methods: A comparative experimental design was employed, where simulated ERP workloads were executed across three integration frameworks: cloud-native, on-premise, and hybrid to measure performance, reliability, security, compliance, Total Cost of Ownership (TCO), and speed of delivery. The major environments evaluated included cloud-native (iPaaS + API Gateway + managed event bus), on-premise (ESB + ETL + RDBMS queues), and hybrid (edge agents + cloud broker). Results: A comprehensive workload of datasets (Order-to-Cash, Procure-to-Pay) experiment, along with thorough testing and intensive hands-on statistics, resulted in the provision of data on performance metrics, including latency, throughput, error rate, and system resilience. The primary findings revealed that the cloud solution is faster in terms of latency (-33%) and error rate (-0.39 pp) compared to the on-premise solution and is also more available. The cost of cloud-native systems is usually low compared to TCO. Hybrid systems are not very costly either, although they have greater resilience in terms of flexibility and control over data. The findings suggest that the choice of an integration strategy depends on the organization’s specific requirements. Scalability, costs, and potential downtime are essential aspects. Conclusion: The study concludes that the cloud-native integrations, in both cases of high volume and sufficiently high latency workloads, tend to be more agile, more performant, and more cost-effective, whereas hybrid models present a desirable compromise between scalability and data control to organizations with strict governance needs. Recommendation: Organizations should align their ERP integration strategy with transaction volume, latency tolerance, and data governance requirements to maximize performance and compliance outcomes.
