Deployment options
You will notice that there are some options we left as default. Let's look at these in a bit more detail to make sure we understand all of the settings required to create a Compute Engine instance.
Region
Regions are geographical locations that are made up of three or more zones. We need to select a region where we can run our VM. The requirements may be related to where most traffic is expected. As we have mentioned, some regions are more expensive than others:
Figure 4.15 – Regions
Make sure the selected region makes sense based on your requirements.
Zone
Make sure you select a zone that suits your requirements. Consider network latency and select a region or zone close to your point of service:
Figure 4.16 – Zones
All zones in a region are connected through a high-bandwidth and low-latency network – usually below 5 minutes for a round trip between each zone.
