Journey of Enhanced & Mindful Architecture - Part 1

Welcome 2025 & cheers to New Beginnings !!

There are amazing & remarkable success in Cloud innovations with architecture designs being the base foundation of those unbelievable achievements. Design enhancements, efficient service selection comes with knowledge, experience & expertise in the domain and above all, vision & need of any Business

Here in this post, I am opening a multi part series of design solutions to requirements & how it got improvised with time & knowledge

Let us see Part 1

Given scenario is a minimal illustration of one of the use cases. Requirement is to notify the admin/team when there is no tag in an EC2 resource.

To simplify

1. Create an event bridge rule to check for any EC2 instances in the account
2. Create a lambda function to check a given Tag/Value in EC2 instances
3. Create an SNS topic and group/team email id to notify when tag/value doesn't exists
4. Now when event bridge rules(with cron scheduler) assess the EC2 Instance(s), irrespective of the state(RUNNING or STOPPED) and if lambda function doesn't find the Tag Value[Project:Team or Tag:Value, as applicable]
5. Lambda has to trigger SNS email notification to the group id

Solution Design for this scenario:

Benefits around this solution:

1. Checks resources at defined periodic intervals, in an automated way
2. EC2 is aimed for monitoring to Tags' existence via a schedule
3. Lambda function will check for defined Tag/Value as expected
4. Teams/Admins are notified even when resource(ec2) are created w/o tags or even if tag/values are removed at a later point in time, as well

In conclusion, this is an automated solution using AWS services efficiently

People who are having urge to suggest better & more efficient ways to do this, hold onto that thought and we will get there in the upcoming series !!
