AWS CloudWatch: Amazon Web Services CloudWatch is one of the available tools developed by Amazon in order to help the client monitor all the resources and applications that they are currently running on Amazon’s cloud. The Cloud watch service is able to collect data in order to assist the client with monitoring their application, as it tracks various metrics and collects log files of the relevant application.
In addition to this, CloudWatch can also be set up in such a way that it sets alarms to mark time points or events, and it can also be set to react to changes in the resources of the client, depending on the parameters that are set. CloudWatch is often used by clients in order for them to get a better read on how they are able to utilize resources, how their applications are running, and to get an idea of the overall health of their applications.
Amazon CloudWatch Benefits
The single platform across applications and infrastructure
The applications that run on micro services architectures specify a huge amount of data in the form of logs, metrics, events. Amazon CloudWatch allows you to access, collect and correlate to the data on a single platform from all your AWS applications, resources, and services that run on AWS & on-premises servers.
To collect metrics in AWS and on-premises
Amazon CloudWatch makes it easy to observe your AWS resources and application. It integrates with more than 70 AWS services like Amazon DynamoDB, Amazon EC2, Amazon S3, Amazon EKS, AWS Lambda, AWS ECS, etc. It automatically specifies one-minute metrics and custom metrics up to one second that helps to look deep into your logs for additional context. The Cloudwatch Agent or API is used to observe your on-premises resources.
Resource optimization and operational performance improvement
The Amazon CloudWatch allows you to set alarms and automate actions based on predefined thresholds or machine learning algorithms. Let’s take an example, the CloudWatch can automatically start Amazon EC2 Auto Scaling or stop an instance to reduce billing overages. The CloudWatch events can trigger workflows with services like AWS CloudFormation, Amazon SNS, AWS Lambda.
