Set up CloudWatch alarms and SNS topic in AWS

What is Amazon CloudWatch?

Amazon CloudWatch is a monitoring and observability service provided by Amazon Web Services (AWS). It helps you collect and track various metrics, log files, and events from your AWS resources and applications. CloudWatch provides valuable insights into the performance, health, and operational state of your AWS infrastructure.

In simple terms, CloudWatch acts as a monitoring tool that allows you to keep an eye on your AWS resources and applications. It gathers data such as CPU usage, network traffic, and storage utilization from your resources. You can view this data in the form of graphs, charts, and alarms in the CloudWatch console.

With CloudWatch, you can set up alarms to notify you when specific conditions are met, such as high CPU usage or low storage space. These alarms can trigger actions or send notifications to help you quickly respond to any issues.

CloudWatch also collects logs from your applications, making it easier to troubleshoot and analyze any errors or issues in your system. You can search and filter logs based on keywords or specific criteria to identify and resolve problems.

What is Amazon SNS?

Amazon Simple Notification Service (SNS) is a fully managed messaging service provided by Amazon Web Services (AWS). It enables you to send and receive messages or notifications to and from various endpoints, such as mobile devices, email addresses, and other distributed systems.

In simple terms, SNS allows you to send messages to different types of recipients or subscribers. You can think of it as a communication hub that helps you distribute information to multiple destinations at once.
