+# Setting up a VPC with CDK in Python
+
+[AWS CDK](https://docs.aws.amazon.com/cdk/latest/guide/home.html) is a very neat way to write infrastructure as code, enabling you to create and provision AWS infrastructure deployments predictably and repeatedly.
+
+You choose your favorite language to code what resources (stacks) you want, and CDK synthetizes them to CloudFormation and helps you to deploy them to AWS.
+
+In this example we see how to setup a VPC using CDK in Python. 
+
+### Install AWS CDK
+
+Follow [this instructions](https://github.com/aws/aws-cdk#at-a-glance).
+
+### Create a virtual environment and install dependencies:
+
+```
+virtualenv venv
+source venv/bin/activate
+pip install -r requirements.txt
+```
+
+Note: If you are starting from a blank project with `cdk init app --language=python` instead, you will we need to manually install resources, such as `pip install aws_cdk.aws_ec2`.
+
+### Define You VPC 
+
+Define how you want your VPC in the file `vpc_example/vpc_example_stack.py`:
+
+```
+class VpcExampleStack(core.Stack):
+
+    def __init__(self, scope: core.Construct, id: str, **kwargs) -> None:
+        super().__init__(scope, id, **kwargs)
+
+        vpc = aws_ec2.Vpc(self, "MiaVPCTest", cidr="10.0.0.0/16", max_azs=3)
+```
+
+
+### Create synthesized CloudFormation template
+
+```
+cdk synth
+```
+
+You can check what changes this introduces into your AWS account:
+```
+cdk diff --profile <AWS PROFILE>
+```
+
+### Deploy to AWS
+
+If everything looks right, deploy:
+
+```
+cdk deploy --profile <AWS PROFILE>
+```
+
+These are the resources that will be created with this command:
+
+![vpc](https://github.com/bt3gl/AWS_Resources/blob/master/CDK_examples/VPC_example/imgs/vpc.png)
+
+
+
+To check all the stacks in the app:
+
+```
+cdk ls
+```
+
+### Clean up
+
+To destroy/remove all the newly created resources, run:
+
+```
+cdk destroy --profile <AWS PROFILE>
+```
+
