Which service provides a secure connection for hybrid cloud setups in OCI?

The service that provides a secure connection for hybrid cloud setups in Oracle Cloud Infrastructure is OCI VPN. This service establishes a secure, encrypted connection between an on-premises network and the Oracle Cloud. It uses open standards and protocols such as IPsec to ensure that data in transit is protected from unauthorized access and eavesdropping. This capability is essential for organizations utilizing a hybrid cloud model, where data and applications may reside both on-premises and in the cloud.

OCI VPN allows organizations to securely extend their on-premises networks into the cloud, facilitating seamless connectivity and resource sharing. The use of virtual private networks is critical in maintaining confidentiality and integrity, especially when sensitive data is involved. This choice is particularly pertinent for organizations looking to integrate their on-premises infrastructure with cloud environments securely.

In contrast, other options such as OCI ExpressRoute, OCI CloudBridge, and OCI Interconnect serve different purposes and may not specifically focus on establishing secure hybrid connections. Therefore, OCI VPN stands out as the most suitable service for this specific requirement.
