ERP for IT Leaders — Architecture, Integration, Operations
For IT leaders and CIOs, architecture decides everything in an ERP: deployment model, integration capability, security and scalability determine how well the system fits the existing IT landscape and runs over the years. This overview shows the central technical criteria.
The IT requirements for the ERP
- Deployment model: true cloud SaaS, private cloud or on-premises — with clear responsibilities
- Integration: open APIs for shop, CRM, logistics and in-house systems
- Security: role/permission concept, SSO, encryption, audit logs
- Scalability & availability: load peaks, SLA, disaster recovery
Cloud vs. on-premises from the IT view
The architecture decision shapes operations and cost for years. Cloud SaaS relieves the IT team of infrastructure and updates but limits customisation depth. On-premises gives full control but ties up IT resources for operations, backup and patches. A solid weigh-up: Cloud ERP vs. on-premises.
Integration and API strategy
- REST/OData: modern, documented interfaces
- Webhooks: real-time events instead of polling
- iPaaS: integration platforms for complex landscapes
- API completeness: is every function truly reachable via API (API-first ERP)?
Security, operations and future-proofing
- IT security: role/permission concept, multi-factor authentication (MFA), encryption, regular audits
- Compliance: data protection and, where relevant, NIS-2 and sector rules
- Operations: monitoring, backup, update strategy
- Architecture trend: modular composable ERP instead of a monolith

Frequently Asked Questions
What should an IT leader watch for in ERP selection?
The deployment model (cloud vs. on-premises), integration capability via open APIs, the security and permission concept, plus scalability, availability and long-term operability.
Cloud or on-premises — what's better from the IT view?
Cloud SaaS relieves IT of infrastructure and updates but limits customisation. On-premises gives full control but ties up resources for operations, backup and patches. The choice depends on skills, compliance and customisation needs.
How important are APIs in ERP selection?
Very important. Open, complete and documented APIs (REST/OData, webhooks) decide how well the ERP connects to shop, CRM, logistics and in-house systems. An API-first ERP exposes every function via interface too.
What security requirements apply to an ERP?
A granular role and permission concept, multi-factor authentication, encryption, full audit logs, plus data-protection compliance and, where relevant, NIS-2 and sector-specific rules.
What does composable ERP mean for IT?
Instead of a rigid monolith, modular building blocks are combined via interfaces. This increases flexibility and eases replacement and extension, but demands a well-thought-out integration and API strategy.
