• Global external Application Load Balancers
• Regional external Application Load Balancers
• Cross-region internal Application Load Balancers
• Regional internal Application Load Balancers

The key benefits are as follows:

• Streamline certificate management: Automated certificate and trust management for backend mTLS through seamless integration with Certificate Authority Service and Certificate Manager.
• Eliminate operational toil: Certificates are automatically rotated based on the workload identity pool's configuration, removing the complexity and manual bottleneck of private key provisioning and maintenance.
• Improve visibility and governance: Gain visibility into communication between distributed services and proactively apply governance to workloads across environments.
