Google Is Ending Gmail’s Third-Party “Send As”: What to Do Before 2027

Key takeaway: For regulated or sensitive communication, authentication and encryption should be treated as architectural requirements, not optional add-ons.

Cloud vs Private Cloud vs Sovereign Cloud vs On-Premise Email

The Gmail change is also a useful trigger for organizations to reconsider deployment strategy. Cloud email offers simplicity, while private cloud, sovereign cloud and on-premise deployment provide progressively greater infrastructure and jurisdictional control. The right model depends on security requirements, regulatory obligations, IT capabilities and data-residency policies.

Private cloud

A private cloud provides dedicated infrastructure for an organization while retaining cloud-style operational characteristics.

Sovereign cloud

A sovereign cloud emphasizes jurisdictional and data-residency control, making it relevant for organizations with strict regulatory or national data requirements.

On-premise deployment

With on-premises deployment, the organization runs the email infrastructure inside its own data center and controls the underlying systems.

XgenPlus supports cloud, hybrid, sovereign-cloud, and on-premises deployment models, including an India-based sovereign-cloud option.
