AWS CloudWatch: Monitoring Your Cloud Infrastructure

Introduction:

Meet Amazon CloudWatch, the superhero of the AWS cloud! 🦸‍♀️ It's like your cloud's personal fitness trainer, always keeping an eye on your applications, ensuring they perform at their best and helping your resources stay in tip-top shape.

Picture CloudWatch as your cloud's detective, gathering data from all your AWS buddies. It not only shows you how everything is running but also lets you set alarms. Think of these alarms as your own superhero signals - if something goes wrong, CloudWatch lets you know right away.

But wait, there's more! CloudWatch doesn't just watch; it acts. It can automatically respond to changes in your cloud environment, ensuring everything stays as smooth as silk. And to make it even cooler, CloudWatch creates a superhero-style dashboard, giving you a colorful and clear view of how your cloud is doing.

In a nutshell, Amazon CloudWatch is like the superhero sidekick you always wanted for your cloud adventures, ensuring everything is A-OK and ready to take on any challenges that come your way! 🚀

Let's give AWS CloudWatch a try! 🚀

We are setting up a simple design to receive email notifications whenever the status of an EC2 instance changes.

1. Sign in to your AWS console.
2. Create an SNS topic for sending emails, similar to the one in this AWS SNS blog.
3. Navigate to CloudWatch from the services panel.
4. Click on Rules in the left side panel.
5. Click on Create Rule.
6. Type in EC2StateChange in the Name text box.
7. Leave default settings and click on Next.
8. Scroll down to Event pattern.
9. Select EC2 from AWS service dropdown list.
10. Select EC2 Instance State-change Notification from the Event type dropdown list.
11. Click on Next.
12. In the Select target(s) section, select AWS Service radio button.
13. Select SNS Topic from the Select a target dropdown list.
14. Select EmailsTopic from the Topic drop-down list.
15. In the Configure tags section, click on Next.
16. Click on Create rule at the bottom of the page.

🎉 Now you will be able to receive an email once an EC2 instance's state changes. 🎉

Let's give our design a quick test! 🧪

The quickest way to test is to simply launch an EC2 instance!
If you're unsure how to do that, check this quick and easy AWS EC2 blog.
