Hey learners! 🚀 You've been diving into AWS services for at least the past 45 days. Ever thought about what happens if a service keeps charging you and you're unaware until your pocket money evaporates? 😅
Well, it's time to take charge! Let's set up something to alert you when your bill hits a certain threshold.
Amazon CloudWatch 🌥️
Amazon CloudWatch is like a watchtower 🏰 overseeing your AWS resources and applications, keeping an eye on how they're performing in real time. It collects and tracks metrics 📊, which are like measurements, for your AWS resources and applications.
Example: Imagine you have a website hosted on AWS. CloudWatch can monitor how many visitors 🚶♂️ your website gets, how long they stay, and if there are any errors 🛑 occurring. It's like having a guard 🛡️ watching over your website's health.
Amazon SNS 📩
Amazon Simple Notification Service (SNS) is like a messenger 📬 for AWS services. It delivers messages 📧 or notifications to different endpoints like email, SMS, or even other AWS services.
Example: Let's say you want to get notified 🚨 whenever there's an issue with your website. You can set up SNS to send you an email 📧 whenever CloudWatch detects a problem, like a sudden increase in error rates. It's like having a messenger bird 🐦 delivering important messages directly to you.
In summary, CloudWatch keeps watch over your AWS resources, while SNS delivers notifications about what CloudWatch observes. Together, they help you keep your AWS environment healthy and running smoothly! 🌟
