AWS Create a VPC manually

As a result of development requirements, a set of Elb with the same formal environment should be deployed for testing; the intention to start the Creation Wizard was created, and AWS failed and had to be manual;

1) Enter vpc options = = = "Your vpc==" to create a vpc=== "fill in the name and CIDR block (it is important that the network is not familiar with the recommendations according to the default fill, of course, this network segment will be large, to avoid future extensibility, but not affected; You can fill in the default 10.0.0.0/16)

2) Create subnets, ideas: According to the needs of several network segments (generally at least 3, two public network, according to the AWS 1a and 1b availability zone, plus the Intranet 1a or 1b can be;

Subnet = = "create subnet = =" When filling in "CIDR block", remember to choose 1a, 1b and other partitions; Here we choose three network segments;

Fill in 10.0.0.0/24,10.0.1.0/24;10.0.2.0/24, etc...

3) Set the routing table; The General 1a 1b of the availability zone to ensure that the external network is through, 1a private subnet only through the above three intranet;

"This is very important to your network's connectivity situation"

All_network is the release no_network is outside the network does not pass

4) Create an Internet gateway with the name, select the vpc you just created

5) Here assign the route to the All_network

Target completion 0.0.0.0/24 Target 2: Select the Internet gateway you just created; the subnet is connected to the network;

How to set up a private subnet, only let the internal Netcom, the outside network does not pass, here according to your choice of private subnet 1a casually open a EC2, to confirm that the network segment to open the minimum default minimum machine (so no cost to produce) association after the shutdown, all access is discarded, both constitute a private subnet , and then set the following diagram in the routing table. Subnet Association is also selected on the setup success;

Such

10.0.0.0/24

10.0.1.0/24

10.0.2.0/24

are in a large sub-network, cut 0, 2 network segments can and external network interoperability, 1 can only be accessed through the other two network segments;

The final routing table should be shown this way;
