AWS Study Notes
1. When creating a VPC and selecting a lease, the difference between dedicated and default is that dedicated hardware devices use independent dedicated hardware devices to facilitate compliance audit and compliance. The default rent is + 10%.
2. The number of servers in a data center cannot exceed 80 thousand
3. The zone AZ required to create a subnet is for high availability.
4. The minimum granularity of AWS physical layer is AZ, not a rack. For example, 10.0.0.1/24 in CIDR in VPC creation can be used for AZ-1A, 10.0.1.0/24 for AZ-1B
5. Use the internet gateway function to access the internet from the public IP address of the virtual machine in the VPC.
6. You can use the managed police and inline permissions. the permissions of inline are deleted.
7. Permission granularity, including create VPC, create internet gateway, attachinternetgateway, and webservices
8. to log on to the GUI, you only need to provide the password, and the command line and development tool must provide the accesskey.
9. ec2 uses the hvm virtualization type, which directly leads to the use of new hardware and drivers for instance types.
10. reboot continues on this server. You can restart stop + start and change the server.
11. "Stop" means "delete". EC2 does not have a delete concept. "Stop" means "delete". After the instance is restarted, the billing method is "recharged ".
12. A new EIP address is assigned. This address is yours, which is very different from the public IP address in Beijing.
