CloudWatch Cost Saving

What is AWS CloudWatch?

Amazon CloudWatch is an observability service provided by Amazon Web Services that allows you to monitor the health and performance of your AWS infrastructure and applications. It collects and keeps track of operational metrics and log files from EC2 instances, RDS databases, VPCs, Lambda functions, and other resources. By gaining visibility into your AWS resources, AWS CloudWatch monitors resource utilization, application performance, and operational sustainability. In the long run, these insights will help you process and sustain your workloads.

A data ingest pipeline, a datastore, and a management console are the three main architectural components of observability solutions. CloudWatch, like most observability solutions, prices its service based on these three factors. Ingesting data into the datastore, retaining data in the datastore, and the visualization/management tools required to work with the data in order to generate insights will all incur additional costs.

AWS CloudWatch Tiers & Pricing

There are two levels of Amazon CloudWatch, free and premium. There are no upfront or commitment fees for either tier. The only distinction is that the free tier is part of the AWS Free Tier, which allows users to try out over 85 AWS products for free.

CloudWatch Free Tier

AWS offers multiple sorts of free tiers:

  • Always free – These services don’t expire and are available to everyone.
  • 12 months months free –  Free for the first 12 months from when you sign up.
  • Trials – These are limited-time trial offerings that begin when you activate the service.

Is AWS CloudWatch Free?

The Amazon CloudWatch free plan is a “Always-free” service that includes the following features:

  • 10 unique metrics
  • 10 alarms
  • 1,000,000 API requests
  • Ingestion of 5 GB of log data and archiving of 5 GB of log data
  • 3 dashboards every month, each with up to 50 metrics

The free plan is generous and provides more than enough space to check out CloudWatch and decide whether the subscription plan you choose is worth the investment. You can learn more about the free tier pricing here.

CloudWatch Paid Tier

Amazon CloudWatch paid tier pricing varies by location, as it does for most AWS products, and it is subject to change. The cost of CloudWatch is determined by the features you use. Here are a few of them:

  • APIs and metric streams
  • Dashboards
  • Alarms
  • Logs/Events
  • Contributor perspectives
  • Canaries

How To Reduce AWS CloudWatch Costs?

Detailed monitoring and observability in Cloudwatch

  • Charges are incurred by detailed CloudWatch monitoring for Amazon Elastic Compute Cloud (Amazon EC2) instances, Auto Scaling group launch configurations, or API gateways.
  • To reduce costs, turn off detailed monitoring of instances, Auto Scaling group launch configurations, or API gateways, as appropriate.

Custom metrics

  • Charges are incurred by monitoring more than ten custom metrics. Custom metrics include those that you created as well as those used by tools such as the CloudWatch agent and application or OS data from EC2 instances.
  • Request metrics for Amazon Simple Storage Service (Amazon S3) and Amazon Simple Email Service (Amazon SES) events sent to CloudWatch incur charges.

CloudWatch metric API calls

  • Charges vary by CloudWatch metric API. API calls that exceed the AWS Free Tier limit incur charges.
  • Third-party monitoring tools can increase costs because they perform frequent API calls.

CloudWatch alarms

  • Charges are incurred by the number of metrics associated with a CloudWatch alarm. For example, if you have a single alarm with multiple metrics, you’re charged for each metric.

CloudWatch dashboards

  • Charges are incurred when you exceed three dashboards (with up to 50 metrics).
  • Calls to dashboard-related APIs through the AWS CLI or an SDK also incur charges after requests exceed the AWS Free Tier limit.

CloudWatch Logs

  • Charges are incurred by ingestion, archival storage, and analysis of Amazon CloudWatch Logs.
  • To reduce ingestion costs, you can re-evaluate logging levels and eliminate the ingestion of unnecessary logs


Amazon CloudWatch is an Amazon Web Services observability solution that lets you track the health and performance of your AWS infrastructure and applications. It gathers operational metrics and log files from EC2 instances, RDS databases, VPCs, Lambda functions, and other resources and maintains track of them. Amazon CloudWatch is subscribed with two tiers: free and premium.
