automatically create a virtual machine. Availability zones and regions AWS classifies Disaster Tolerance for virtual machines into two levels: Availability zones and regions. The former is geographically isolated, and the latter is engineering isolation. It can be simply understood that the former is the highest level of disaster tolerance, while the latter is a low-cost disaster tolerance. A cluster can only be in one regions, but many availability

How does an instance (instance) in a VPC access the Internet after a VPC is created on the Amazon cloud? There are usually two ways of doing this: Assigning a public IP address directly Associating a VPC to an Internet gateway This way, the subnet where the instance resides, belongs to the public subnet 2. Via Nat Gateway or NAT instance In the routing table for each subnet, set the default route to Nat Gateway or NAT instance This way, the subnet where the i
