Public cloud environments are multi-tenant and VMs share the physical server which can result in VMs fighting for resources. Because a bare metal cloud is made up of dedicated servers, this problem is avoided.
People with sleep apnea often wake up suddenly due to shortness of breath. Upon waking, they may also choke, snort, or gasp. You may not even be aware of some of these symptoms while you sleep, but waking up feeling out of breath is a strong indicator that you have sleep apnea.
Labored breathing is distinguished from shortness of breath or dyspnea, which is the sensation of respiratory distress rather than a physical presentation. Still, many simply define dyspnea as difficulty in breathing without further specification, which may confuse it with e.g. labored breathing or tachypnea (rapid breathing). Labored breathing has occasionally been included in the definition of dyspnea as well.
