Cloud B2B integration does not just mean „moving the EDI server into someone else's data centre“ — it is a different operating model with its own benefits and limits. For a company evaluating where to run its EDI/Peppol infrastructure, the difference between a cloud-native approach and a classic on-premise setup shows up in three areas: time to implement, cost structure and control over data.
This article walks through the concrete pros and cons of cloud B2B integration, and when a hybrid model actually makes sense.
Benefits of the cloud approach
- Fast implementation — no physical hardware procurement. A typical cloud B2B integration goes in 4–8 weeks, while classic on-premise can take 12–24 weeks due to procurement and install cycles.
- Lower CAPEX — no capital outlay for servers, network gear or perpetual software licences. Everything moves to operating expense.
- Automatic upgrades — security patches, new Peppol BIS updates, schemas and validators. No need to keep an in-house team for maintenance.
- Predictable OPEX — monthly fee with clear volumes and SLA. No surprise hardware refresh costs.
- On-demand scalability — for seasonal peaks (pre-holiday, quarterly close), capacity scales up and down without infrastructure rework.
Drawbacks and risks of the cloud approach
- Vendor dependency — your system is tightly coupled to the chosen cloud provider. Migration is possible but not trivial.
- Data sovereignty — where the data physically sits. For EU-regulated companies, a US cloud provider can mean GDPR and Cloud Act complications.
- Egress costs — large archive migrations or on-prem-to-cloud integrations can rack up egress fees.
- Latency to local ERPs — if the ERP is in Zagreb and the cloud gateway is in Frankfurt, an extra 30–50 ms per call can affect batch processing.
REDOK approach: cloud-native on AWS EU
The REDOK platform runs cloud-native on AWS EU (Frankfurt region), with replication kept within EU territory. That addresses the key sovereignty concern for Croatian and European customers: data does not leave the EU jurisdiction, the contractual relationship is with an EU company (direct GDPR coverage), and the certifications for ISO 27001, eIDAS and Peppol AP are issued by EU authorities.
For hybrid setups, REDOK supports a model where master data stays on-premise (ERP, accounting, partner master) and the cloud layer is used only for routing, validation and archive. That combines data control with operational savings.
When hybrid makes sense
The hybrid model is especially relevant for regulated industries (banks, insurance, pharma) where the regulator requires local control over master data, and for enterprise customers with large existing on-prem investments who do not want to write off the existing CAPEX. In both cases, cloud is introduced incrementally — for new use cases and new partners — without dismantling the existing infrastructure.
Summary
Cloud B2B integration is not „good or bad“ — it is a trade-off between speed, control and cost. For most SMBs, cloud is clearly the better choice. For enterprise and regulated industries, hybrid is a realistic option that combines benefits of both.
