Optimizing low-latency VM-to-VM networking
WHAT IT TESTS: networking performance depth. OUTLINE: cluster placement groups, enhanced networking and SR-IOV, larger instances for more bandwidth. RED FLAG: ignoring that tight placement concentrates instances in one AZ, trading availability for latency.
WHAT IT TESTS: whether you can squeeze latency out of the network while weighing the availability cost. ANSWER OUTLINE: use cluster placement groups or proximity placement groups to pack instances physically close, enable enhanced networking with SR-IOV and elastic network adapters to bypass the hypervisor, choose instances with higher network bandwidth, and consider DPDK for kernel bypass.
