Security requirements

The following security requirements are valid for creating hybrid environments:

• You must enable the Kerberos authentication method. It ensures secure communication with the services, regardless of whether they reside in public cloud or on-premises. Both public cloud and on-premises clusters must be Kerberized.
• Kerberos bidirectional cross-realm trust setup must be established so that on-premise KDC and public cloud KDCs trust each other.
