Is it necessary to use load balance if I use Cluster or Multi-Cluster

Is it necessary to use a load balance if I use Cluster or Multi-Cluster?

1. If yes, why do i need to add a load balance to Cluster or Multi-Cluster why?
2. If no, when should I create a load balance for AMS? (For a single VM or a Cluster or a Multi-Cluster or other configurations?)

@williewhcheng The load balancer acts as the entry point for both viewers and publishers. It receives user requests and intelligently directs them to an appropriate node in either the origin or edge group, based on the current load and availability of resources. The load balancer is crucial for distributing traffic evenly across the cluster, thereby optimising performance and avoiding overloading any single node.

@amarantmeida "https://antmedia.io/docs/guides/clustering-and-scaling/manual-configuration/multi-level-cluster/#how-to-configure-multi-level-cluster " In the Azure environment,a load balancer must be used to combine the components(2~N clusters) if I want to create a cluster or multi-cluster. On ther other hand, the load balance setting must includ all of cluster devices (Origins+Edges), correct?

[amarantmeida]

@williewhcheng That is correct. In a multi-level cluster, a load balancer is essential to combine the multiple clusters into a unified system. The load balancer must include all nodes (origins and edges) within the clusters to distribute traffic intelligently across all available resources and
maintain a unified point of entry for clients, regardless of their geographic location or the cluster they need to connect to. Let us know for any follow-up queries.

@amarantmeida Thank you very much for your prompt feedback. I am currently facing some issues while creating a cluster enviornment:

1. I have already used a template with ARM(Azure resource management) to deploy a cluster environment, and it is working for me now. However, is it correct to add "nodeGroup=GROUP_NAME in conf/red5.properties file" for each device (all Origins + Edges) for a creating multi-cluster (EU + US -->2 cluster infrastructures)?
2. Each AZURE Application Gateway has a load balancer, how can I combine it if I have a multi-cluster setup.
3. If I have two clusters, one in the EU and one in the US, how can I determine which cluster is best for the users? Should I need to create something to ensure the best latency?

P.S.: A single domain, e.g., ams.veretos.com, is used globally.
