Part 4: Creating a Load Balancer and Assigning a Certificate to the Listener in OCI

This final part of the series details how to create a load balancer in Oracle Cloud Infrastructure (OCI) and secure it by assigning an SSL certificate to its listener. This ensures secure and efficient traffic distribution for applications.

Step 1: Access the Load Balancer Service

1. Log in to OCI ConsoleI log in to the OCI Console and navigate to Networking > Load Balancers.

   
   

2. Create a New Load Balancer

   
   

   • I click Create Load Balancer and provide the following details:

     • Name: A descriptive name for the load balancer.

     • Type: Public for internet-facing or Private for internal applications.

     • Shape: I choose a shape (e.g., 10 Mbps or 100 Mbps) based on expected traffic.

       
       

3. Assign VCN and Subnets

   
   

   • I select a Virtual Cloud Network (VCN) and subnet. These subnets provide access to the application backend.

     
     

Step 2: Configure Backends

1. Define Backend Servers

   
   

   • I add backend instances or IP addresses.

   • I set the backend port (e.g., 80 for HTTP or 443 for HTTPS).

     
     

2. Health Check Configuration

   
   

   • I configure health checks to monitor backend health by providing:

     • Protocol: HTTP or HTTPS

     • Path: Endpoint to check (e.g., /healthcheck)

     • Interval and Timeout: Define intervals for health checks.

       
       

Step 3: Add a Listener

1. Create a Listener

   
   

   • I navigate to the Listeners section and click Add Listener.

   • I provide the following details:

     • Protocol: HTTPS

     • Port: 443 for secure connections.

     • Certificate: I choose one of the following:

       • OCI Certificates: Select from the OCI Certificates service.

       • Custom Certificate: Upload an SSL certificate and private key in PEM format.

   
   

Follow this step by step guide:

Conclusion

By following these steps, I successfully created a load balancer and assigned an SSL certificate to its listener in OCI. This setup ensures efficient traffic distribution and secure communication, supporting a scalable and robust application infrastructure.

With this final step, the series concludes. I hope these guides have been valuable in setting up and optimizing cloud resources in OCI.
