transmission latency. Cloud providers in some regions offer bundled

network connectivity with a guaranteed speed (part of the SLA), but
normally your Internet service provider controls your network speed, and
this is often separate from your cloud provider agreement.
Remember, cloud services are not hosted locally; they are delivered over
a network. The network connection is your single point of failure. Figure 3-
9 shows a geographically distributed collection of cities using cloud
services. Network connectivity to cloud services should be fast and
reliable; otherwise, the impact on productivity will be negative. You should

consider multiple network paths to your cloud provider in case one fails or
becomes too congested.

CPU
The central processing unit (CPU) is the core of any computing device; it is
the brain that performs all calculations. Both physical and virtual servers
might have a single-core processor (one CPU) or multiple-core processor.
