CloudHub provides a load balancing service for all integrations. You can use the default load balancing service or obtain a xref:cloudhub-dedicated-load-balancer.adoc[dedicated load balancer]. For TLS version requirements and JVM TLS configuration when using the shared load balancer, see xref:dedicated-load-balancer-tutorial.adoc#shared-load-balancers[Shared Load Balancers].

The CloudHub load balancing service does round robin load distribution across workers, which allows workers to scale linearly as they receive more requests. The load balancing service also provides transparent switchover when an application is upgraded. See xref:managing-applications-on-cloudhub.adoc[Manage Applications on CloudHub].

think that saying "It doesn't support TLS 1.3." is obvious and shouldn't be included and moreover as you're mentioning the IMPORTANT note below.


[IMPORTANT]
--
If your application uses only TLS 1.3, for example `jdk.tls.client.protocols=TLSv1.3`, connectivity to internal MuleSoft subsystems that use TLS 1.2 fails. Handshake exceptions or connection failures can occur.

Keep TLS 1.2 enabled in your application configuration. For compatibility with the shared load balancer and platform services, set `jdk.tls.client.protocols=TLSv1.2,TLSv1.3`.
