We are migrating some workloads to AWS and Azure simultaneously. Managing identity and access management across both is turning into a nightmare, especially for regulatory compliance. What are the best practices for ensuring consistent without multiplying administrative overhead or creating massive security gaps across our entire enterprise infrastructure?

Implementing a centralized identity provider using SAML 2.0 or OIDC is absolutely critical here. You shouldn't manage local users in AWS and Azure separately. Instead, federate your enterprise identity provider, like Okta or Ping Identity, directly to both cloud environments. This ensures a single source of truth for user access. Additionally, leverage Infrastructure as Code to deploy standardized IAM roles and policies consistently. Automating this process reduces human error significantly, allowing you to enforce continuous compliance monitoring and audit trails seamlessly across your entire multi-cloud estate.
Centralizing the identity provider sounds great in theory, but how do you handle cloud-specific features or roles that don't map cleanly to your external IdP groups? Standardizing everything sometimes strips out granular control.
Use cloud infrastructure entitlement management tools to visualize permissions across both platforms and instantly discover over-privileged accounts.
Completely agree with this approach. CIEM platforms are absolute lifesavers for preventing privilege creep, which is one of the biggest risks to overall cloud security when managing multiple environments.
To address that, you should map your central IdP groups to specific, narrowly scoped local roles inside AWS and Azure rather than trying to standardize the roles themselves. The central identity system only authenticates the user and passes their group membership; the cloud native IAM platform dictates exactly what permissions that group translates to locally. This gives you central governance while fully preserving granular, cloud-specific access controls.
