Load Balancing and High Availability
Using the Built-In Round-Robin Algorithm
MetaDefender Managed File Transfer supports multiple MetaDefender Core servers for load balancing and high availability. To add another server, repeat the steps above.
Using an External Layer 7 Load Balancer
Load balancing can also be achieved using an external Layer 7 load balancer to manage multiple MetaDefender Core servers. In this configuration, MetaDefender Managed File Transfer communicates directly with the load balancer. The load balancer must support sticky sessions (using cookies) for this setup to work.
For more details, visit the Using external Load Balancer page in the MetaDefender Core user guide.
