We have recently migrated our legacy workloads to VMware SDDC, and planning to change our Microsoft Exchange(MS Exchange 2016) Load balancer from hardware appliance to VMware NSX Load balancer.
Current hardware load balancer is a simple IP based one leveraged from the Fortinet Hardware Firewall.
VMware SDDC infra : VCF 3.5.1
Exchange VMs are connected to DVS port group and not using any Vxlan functionalities, So We cannot make use of inline(transparent)LB feature due to the fact that the default Gateway for the VMs are not on the ESG.
Appreciate if anyone can provide the best practices to use One arm LB method or any thoughts on implempenting it in a production environment.
Every application has it's own requirements for load balancing. IIRC for Exchange it's Layer 7 without session persistence, but I would suggest to refer to Exchange documentation for exact specs.
