If you plan to make the communication of your site visitors to be secure by using HTTPS then you need to use Public SSL/TLS Certificate. You can do this by requesting for a Public Certificate via AWS Certificate Manager (ACM).

Below are the advantages of using Public SSL/TLS Certificate provided by AWS Certificate Manager.

  • No charges = Free.
  • Auto renew – No need to worry on expiring SSL/TLS Certificate. ACM Automatically does this for you.
  • Easy integration with Amazon Web Services (AWS) products such as CloudFront, Elastic Load Balancer, API Gateway and many more.

Check the step-by-step guide on how you can request a Public SSL/TLS Certificate for HTTPS access of your website/domain.

Requesting for a Public SSL/TLS Certificate

Login to AWS Console and head to AWS Certificate Manager.

Note: AWS Certificate Manager is a regional service, therefore make sure to be in the correct AWS Region. If you are new to AWS just select N. Virginia (us-east-1) as it is one of the cheapest regions.

On the AWS Certificate Manager page, click on Get started.

On the next screen, make sure to select the Request a public certificate, then click on Request a certificate.

Under Add domain names. Enter the following.

*.[Your Domain]
Example:
*.chargedneutron.com
The * represents a wildcard. This will allow you to use the SSL Certificate to any subdomains that you want like www.domain.com, images.domain.com, sites.domain.com, mobile.domain.com
[Your Domain]
Example:
chargedneutron.com
Apex Domain or Naked Domain Name. Your domain name without subdomains. Use this if you do not want to use www in front of your website.

Then click on Next.

Select DNS Validation, then click on Review.

AWS Lambda Console: Accessing Environment Variables via Python

Editing configuration values inside the code is a high risk for error since there is a high chance that not only the values that you are changing you will change, you might even delete a letter or edit a line. In order to avoid this risk, you want your code to be able to accept configuration values at run time. This is extremely useful when developing codes on different environments like development, testing and production.

With AWS Lambda you can reuse your code on different environments using the Environment Variables.

Below is the way to use Environment Variables on AWS Lambda Console using Python 3.6.

Note: This is the same way to use Environment Variables on Python 2.7 and Python 3.7.

Environment Variables Setup

The Environment Variables section can be found under the Function Code section.

Environment Variables are Key/Value Pairs. The Key is what you will use on your Lambda Code, to access its Value. Continue reading AWS Lambda Console: Accessing Environment Variables via Python
