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.
See your doctor as soon as possible if you have: 1  Shortness of breath after slight exertion or when you're at rest. 2  Shortness of breath that gets worse when you exercise or are physically active. 3  Abrupt awakenings with shortness of breath or a feeling that you're choking â these may be symptoms of sleep apnea.
