Certificate Rotation

Replacing expiring or compromised SSL/TLS certificates used by SDDC Manager and other components.

SDDC Manager Role

The central point of management for certificates in vCloud Foundation. It simplifies deploying and managing them across the infrastructure.

Components Using Certificates

Various components in vCloud Foundation, like vCenter Server, NSX Manager, and virtualized services, rely on SSL/TLS certificates.

Prerequisites for Certificate Rotation

Before rotating certificates, ensure your vCloud Foundation environment is correctly configured, network connectivity is reliable, configurations are backed up, risks are assessed and understood, and valid new certificates are available.

Study Notes

Certificate Rotation in vCloud Foundation 5.2

  • Certificate rotation in vCloud Foundation 5.2 replaces expiring or compromised SSL/TLS certificates used by the SDDC Manager and other components.
  • This is critical for security and avoiding service disruptions.
  • The SDDC Manager centrally manages certificates, streamlining deployment and management across the infrastructure.
  • vCenter Server, NSX Manager and other virtualized services use these certificates.

Prerequisites for Certificate Rotation

  • Configure the vCloud Foundation environment, including vCenter Server and other dependent services correctly.
  • Maintain consistent, reliable network connectivity between the SDDC Manager and all connected components.
  • Backup all configuration data, including certificates, for recovery if issues occur.
  • Understand potential risks and impacts of the rotation procedure, especially network configuration.
  • Obtain and validate new certificate files from trusted sources to prevent security vulnerabilities.

Steps for Certificate Rotation

  • Initiate certificate rotation using the vCloud Foundation user interface or API within vCloud Director or the vSphere Web Client.
  • The SDDC Manager automatically updates components, synchronizing the new certificate with relevant virtualized services.
  • Configure the new certificate in the SDDC Manager to match expected parameters.
  • Verify certificate installation by checking SSL certificate details for all services and testing component connections.
  • Post-implementation, validate system functionality and ensure continuous service operation (network services and application availability).

Considerations During Certificate Rotation

  • Minimize downtime during rotation using efficient deployment strategies.
  • Implement alerts for network and service performance changes during and after rotation.
  • Rigorously test the new certificate to guarantee proper deployment and avoid service disruptions.
  • Create a complete rollback plan if problems arise with the new certificate.
