 - You create subnets for a VPC. These subnets will be split evenly across availability zones (for redundancy) and private/local (whether they have internet access or not).
 - Behind the scenes (if using TF), internet gateway, routing tables, attachments will all be created for you. If using CF you will need to create these yourself.
 - A security group is a firewall that is _attached to an EC2 instance_. A security group belongs to a VPC. You can permit instances to talk to each other by setting the source and destination to be the security group itself. You can control ports/ips exactly on an instance basis using security groups.

+### Single instance
+
+As it terminates on the Ec2 instance itself, you need to ammend the nginx config locally. This is specific for each application you are deploying.
+
+<https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/https-singleinstance-nodejs.html>.
+
+You need to generate a certificate locally.
+
+`pip install certbot`
+
+`sudo certbot certonly --manual --preferred-challenges=dns --email dtomlinson@panaetius.co.uk --server https://acme-v02.api.letsencrypt.org/directory --agree-tos -d "*.panaetius.co.uk"`
+
+### Load balanced
+
+You have two options:
+
+1. Terminate on the load balancer (easiest).
+
+<https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/configuring-https-elb.html>.
+
+You can use AWS Certificate manager to generate your SSL cert, or you can upload your own.
+
+Use a .config file as documented above and EB will handle the rest.
+
+2. Pass through to the instance.
+
+<https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/https-tcp-passthrough.html>.
+
+If you do this you need to set up termination on the EC2 instances using the config for a single instance above.
+
+You can TCP pass through without the load balancer decrypting the traffic. The traffic is encrypted all the way to the instance. The instances between themselves are HTTP.
+
+Additionally you can configure end-to-end encryption between the EC2 instances if you have strict security requirements.
+
+<https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/configuring-https-endtoend.html>.
