Updating AWS Managed Prefix Lists

I was working with a customer the other day trying to come up with a way to import a bunch of IP addresses into a white list on AWS. We came up with the approach of using Managed Prefix Lists in VPC. I wrote some Python in order to grab some code from an API… Continue reading Updating AWS Managed Prefix Lists

Automating Security Group Rule Removal

I’m using an Amazon Web Services Security Group as a way to allow traffic into an EC2 instance for the instance’s users. The users can give themselves access through a web interface that I wrote for them. Maybe I’ll cover that in a different post. I found recently that the Security Group was nearing its… Continue reading Automating Security Group Rule Removal

EC2 Reservation Notification

I realized today that I haven’t updated my EC2 reservations recently. Wondering why I never did this I came to understand that there was no way that I was getting notified that the reservations were expiring. I spent the day putting together a script that would look through my reservations, assess the time of their… Continue reading EC2 Reservation Notification

This is a simple… Continue reading Security Group ID Finder

Later in the pipeline I wanted to edit that object to append the status of resources created by this pipeline. In order to do… Continue reading Querying and Editing a Single Dynamo Object

EC2 Action Slack Notification

I took a brief break from my Lambda function creation journey to go on vacation but, now i’m back! This function will notify a Slack channel of your choosing when an EC2 instance enters “Starting, Stopping, Stopped, or Shutting-Down” status. I thought this might be useful for instances that reside under a load balancer. It… Continue reading EC2 Action Slack Notification

Automatically Transcribing Audio Files with Amazon Web Services

I wrote this Lambda function to automatically transcribe audio files that are uploaded to an S3 bucket. This is written in Python3 and utilizes the Boto3 library. You will need to give your Lambda function permissions to access S3, Transcribe and CloudWatch. The script will create an AWS Transcribe job with the format: ‘filetranscription’+YYYYMMDD-HHMMSS I… Continue reading Automatically Transcribing Audio Files with Amazon Web Services
