What are the requirements for building a dlb (dedicated load balancer)? in MuleSoft 240

 What are the requirements for building a dlb (dedicated load balancer)? in MuleSoft

Here are the key requirements for building a Dedicated Load Balancer (DLB) in MuleSoft 4:


  • Anypoint VPC: DLBs are deployed within an Anypoint VPC (Virtual Private Cloud) environment. You'll need to create or have access to an existing Anypoint VPC before creating a DLB.

  • MuleSoft Administrator Role: Creating and managing DLBs requires administrative privileges within your Anypoint Platform organization.

DLB Configuration:

  • Name: Choose a unique name for your DLB that identifies it within the Anypoint Platform.

  • Workers: Specify the number of worker instances that will handle incoming traffic. This number determines the level of processing power and scalability for your application.

  • Certificates: You must associate at least one SSL certificate with your DLB to enable secure communication (HTTPS) between clients and the DLB. The certificate needs to be in PEM format and contain both the public and private keys.

  • Optional: You can configure Mutual Authentication (two-way SSL) for added security, requiring client certificates for authentication.

  • Inbound Access: Define the allowed IP addresses or CIDR blocks that can access your DLB. By default, all public traffic is allowed ( You can restrict access for enhanced security.

Additional Considerations:

  • Mapping Rules: Optionally define mapping rules to route traffic to specific worker instances based on message content (e.g., path, headers) or other criteria.

  • Monitoring: MuleSoft offers monitoring capabilities to track DLB performance metrics like worker availability and traffic distribution.

Deployment and Management:

  • Deployment Options: You can create and manage DLBs through various methods:

  • Runtime Manager: The Anypoint Platform Runtime Manager provides a web-based interface for creating, configuring, and monitoring DLBs.

  • MuleSoft CLI: The Anypoint Platform CLI (command-line interface) offers programmatic access for managing DLBs through commands.

  • CloudHub API: The CloudHub REST API allows programmatic creation and configuration of DLBs using API calls.

  • HTTPS Termination: DLBs typically perform HTTPS termination, meaning they handle SSL encryption/decryption for incoming requests. The decrypted traffic is then forwarded to your worker instances, which may or may not require additional SSL configuration depending on your application setup.

By fulfilling these requirements and following best practices, you can effectively configure and utilize Dedicated Load Balancers within your MuleSoft 4 applications to distribute traffic, enhance scalability, and improve security for your integration flows.
