Load Balancing

I would like to set up two load balancers with two network interfaces on each load balancer. Is this possible with the Digital Ocean Loadbalancer configuration?

Example: Gives redundancy and scalability

—-ABC.COM (Network1) —LB1—-App Server 1
—-DEF.COM (Network2) —LB1—-App Server 2
—-ABC.COM (Network1) —LB2—-App Server 2
—-DEF.COM (Network2) —LB2—-App Server 1

Hello,

I believe that this can be achieved with HAProxy installed on a Droplet together with a Floating IP as described here:

I believe that this is not doable with the Managed Load Balancers. However, the Managed Load Balancers are monitored for availability. If any anomalies are detected, DigitalOcean will automatically correct them and fix them. The main point of the Managed Load Balancers is that they will continue running smoothly without any extra work from you.

As DigitalOcean now offers different types of Managed Load Balancers, for busy sites, services, or endpoints where high performance is a must, you could select the Large Managed Load Balancer.

While handling increased system load is a common concern, decreasing downtime and eliminating single points of failure are just as important. High availability is a quality of infrastructure design at scale that addresses these latter considerations. In this guide, we will discuss what exactly high availability means and how it can improve your infrastructure’s reliability.
