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.
A Discovery Health answered. Trouble with breathing or shortness of breath, which is known as dyspnea, is a common symptom of heart failure. This happens when excess fluid builds in the lungs, which is known as pulmonary edema. As the build up of fluid increases, it may cause difficulty in breathing that interferes with sleep.
