For an organization migrating its Mule applications and load balancer to CloudHub while preserving its public URL, the most straightforward and cost-effective approach involves leveraging CloudHub's shared load balancer (SLB). Here's how to do it:
* Deploying Mule Applications to CloudHub:
* First, deploy your Mule applications to CloudHub. This involves packaging your Mule applications and using the Anypoint Platform to deploy them to CloudHub.
* DNS Configuration:
* Update your DNS settings to ensure the base URL (https://api.rutujar.com) points to the CloudHub shared load balancer. Specifically, create or update a CNAME record for api.rutujar.com to point to the CloudHub SLB's A record.
* Configuring Shared Load Balancer (SLB):
* In CloudHub, configure the SLB to handle incoming traffic and route it to the appropriate Mule applications.
* Apply mapping rules in the SLB to map the base URL and its paths to the corresponding Mule applications. This ensures that requests to https://api.rutujar.com are correctly routed to the specific Mule application endpoints.
* Steps to Apply Mapping Rules:
* In Anypoint Platform, navigate to the Runtime Manager and select the application deployed on CloudHub.
* Configure the SLB settings by defining the domain and URL mappings. For instance, set rules that map requests from https://api.rutujar.com/app1 to the corresponding Mule application app1.
* Benefits of Using SLB:
* Cost-Effective: The shared load balancer is a more economical option compared to a dedicated load balancer (DLB).
* Simplicity: Using SLB simplifies the deployment process, as it requires less configuration and management compared to setting up and maintaining a dedicated load balancer.
* Consistency: Preserves the public-facing URL structure, ensuring a seamless transition for users and clients accessing the APIs.
