Resizing Storage Volume for AWS EC2 Windows without Restarts/Downtime

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?

Yes, it is possible.

Check the instructions below.

Test Windows Server

AMI Microsoft Windows Server 2016 Base
Instance Type t2.micro
Storage 30 GiB – General Purpose SSD (gp2)

Storage Size

We are increasing the Storage size from 30 GiB to the target size of 50 GiB.

You can set any size that you want as long as it is bigger than the current size.

Resizing Storage

To resize the volume of the Windows Drive on AWS you can follow the steps below. Continue reading Resizing Storage Volume for AWS EC2 Windows without Restarts/Downtime

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
