To get the AWS Region where your Lambda Function is running you will need to import the os module.
import os
Then from the os module, you need to get the value of AWS_REGION from the environ mapping variable. This will return the AWS Region where the Lambda Function is running.
runtime_region = os.environ['AWS_REGION']
Note: The way of getting the Runtime AWS Region of your Lambda Function is the same as when you get a Lambda Environment Variable.
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.
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 <strong>Get started</strong>.
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 <strong>Review</strong>.
To use GoDaddy Domains with Amazon Web Services (AWS) products such as Elastic Load Balancers, CloudFront, API Gateway, etc., you will need to associate your domain with AWS Route 53 DNS.
Follow the step-by-step tutorial below on how to associate your GoDaddy Domain to Amazon Route 53.
For the purpose of demonstration, I will be using my sample domain name – chargedneutron.com.
Problem: You are running a critical Windows Server on AWS EC2 and the C: drive is almost full (storage volume) but it should zero downtime (No Restart, No Stop then Start). Is this possible on AWS EC2?
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.
