In the next screen, in the left-hand side menu, Basic Information should be selected.In the next screen, give your App a name (I named my app monitoring-bot) and pick the Workspace you want to develop your app in (choose the Workspace that you created above).In the next screen, click From scratch.This will enable us to publish notifications from our AWS Lambda function. Next, in your Slack Workspace, create a Slack channel where the notifications from the AWS Lambda function will be published (I named my Slack channel aws-notifications).The entitlements for the free tier are more than sufficient for the solution described in this blog.įollow the instructions below to create a free Slack Workspace for yourself (unless you already have one): Create a free Slack Workspaceįor those that are unaware, Slack provides a free plan for creating your own Slack Workspace. If any running Amazon EC2 instances are found, the AWS Lambda function will post a slack message in a channel, with details about the running Amazon EC2 instances.The AWS Lambda function will check all the AWS regions for any running Amazon EC2 instances.Everyday, at a predefined time, Amazon CloudWatch Events will trigger an AWS Lambda function.High Level Architectureīelow is the high-level architecture for the solution. If any are found, a Slack message is posted into a channel, with details about these running Amazon EC2 instances. Daily, at a predefined time, a check is done in all the Amazon regions for any running Amazon EC2 instances. In this blog, I will introduce you to a solution I developed sometime back, to provide visibility of all the running Amazon EC2 instances. Unfortunately, I have heard of stories where people forget to turn off their Amazon EC2 instances, only to find out at the end of the month that they have used up all of their free tier entitlements for the month and instead have to pay for the expenses out of their pocket (for such scenarios, I would recommend contacting AWS Support as they are quite understanding and can provide you with a credit to offset the out-of-pocket expenses).

For short-term projects, you do not need to purchase a physical server, which might end up un-used after the project finishes.

Cloud computing empowers people by letting them provision compute resources quickly and cheaply.
