TL;DR: Cloud and on-premise identity infrastructure differ less on feature checklists than on where security, compliance, and operational control boundaries sit, according to Ory. For IAM teams, the practical question is how deployment model changes governance, trust, and integration across human, workload, and agent identities.
NHIMG editorial — based on content published by Ory: Cloud vs. On-Premise: Key Differences, Pros, and Cons Explained
Questions worth separating out
Q: How should security teams choose between on-premises and cloud IAM?
A: They should choose the model that can prove control ownership, auditability, and lifecycle governance for their actual environment.
Q: What breaks when identity governance is split across cloud and on-premise systems?
A: The biggest failure is inconsistent control ownership.
Q: How should security teams govern workload identities across hybrid environments?
A: Security teams should centralise ownership, inventory every non-human identity, and enforce consistent policy across cloud, SaaS, and on-prem systems.
Practitioner guidance
- Inventory identity control ownership across environments Document where authentication, authorisation, token issuance, logging, and revocation are enforced in cloud, on-premise, and hybrid paths.
- Test federation and revocation across boundary conditions Validate that OIDC, SAML, and API-based sessions can be revoked cleanly when identities move between environments or providers.
- Align workload identity with deployment topology Ensure service accounts, secrets, and certificates have explicit scope and rotation rules that follow the workload, not the server or platform.

Ory's full IAM perspective covers the operational detail this post intentionally leaves for the source:
- Deployment-specific cost, security, and compliance considerations across cloud and on-premise models
- Practical differences between hosted and self-managed identity infrastructure for IAM operations
- How hybrid identity setups affect scalability, integration, and control ownership decisions
- The article's own framing of where identity infrastructure fits in zero trust and compliance planning

Deployment choice is an identity governance decision, not just an infrastructure decision. Cloud and on-premise models change where identity controls are enforced, audited, and remediated. That means the maturity test for an IAM programme is whether it can hold policy, evidence, and revocation together across environments. The practical conclusion is that identity architecture should be evaluated as a control plane, not as a hosting preference.
A few things that frame the scale:
- 88.5% of organisations acknowledge that their non-human IAM practices lag behind or are merely on par with their human identity and access management efforts, according to the 2024 Non-Human Identity Security Report.
- Only 19.6% of security professionals express strong confidence in their organisation's ability to securely manage non-human workload identities, according to the same report.
A question worth separating out:
Q: Why does Zero Trust matter for both cloud and on-premise identity stacks?
A: Because the deployment model does not remove the need to verify each access request and each session continuously. Zero Trust keeps the policy question focused on identity and context rather than network location, which is essential when users, workloads, and federated identities move between environments.
