10 Things You Can Do Today to Lower AWS Costs

AWS's wide range of services and pricing options provide the flexibility needed to effectively manage your costs and maintain performance and capacity according to your business requirements.

Here are 10 tactics you can do today using existing Compucloud tools, services, and help to reduce AWS costs.

1. Identify Amazon EC2 instances with low utilization and reduce costs by stopping or adjusting the size.

Use AWS Cost Explorer Rightsizing recommendations to obtain a report of EC2 instances that are inactive or have low utilization. You can reduce costs by stopping or reducing these instances. Use AWS Instance Scheduler to automatically stop instances.

Identifies Amazon EBS volumes with low utilization and reduces costs by creating spanshots and then deleting them.

EBS volumes that have very low activity (less than 1 IOPS per day) over a 7-day period indicate that they are probably not in use. Identify these volumes by checking Trusted Advisor for underused Amazon EBS volumes. To reduce costs, first take a snapshot of the volume (if you need it later) and then delete these volumes. You can automate the creation of snapshots using Amazon Data Lifecycle Manager.

Analyze the use of Amazon S3 and reduce costs by taking advantage of lower cost storage levels.

Use S3 Analytics to analyze storage access patterns in the object data set for 30 days or more. It makes recommendations on where you can take advantage of S3 Infrequent Access (S3 IA) to reduce costs.

Identify instances of Amazon RDS, Amazon Redshift with low utilization and reduce costs by stopping (RDS) and pausing (Redshift).

Use Trusted Advisor's Amazon RDS inactive database instance check to identify database instances that haven't had any connections in the past 7 days. To reduce costs, stop these database instances using automations.

Analyze the use of Amazon DynamoDB and lower costs by taking advantage of automatic or on-demand scaling.

Analyze DynamoDB usage by monitoring 2 metrics, ConsumedReadCapacityUnits and ConsumedWriteCapacityUnits, in CloudWatch. To automatically scale (in and out) the DynamoDB table, use the AutoScaling function. With these steps, you can enable AutoScaling on existing tables. Alternatively, you can also use the on demand option. This option allows you to pay per request, so you only pay for what you use.

Review networks and reduce costs by eliminating inactive load balancers.

Use Trusted Advisor's inactive Elastic Load Balancing check to get a report of load balancers that have a RequestCount lower than 100 in the last 7 days and remove these balancers.

Use spot instances of Amazon EC2 to reduce EC2 costs

If your workload is fault-tolerant, use spot instances to reduce costs by up to 90%. Using EC2 Auto Scaling, you can launch on-demand and spot instances to meet a target capacity.

Review and modify the EC2 AutoScaling group settings.

An EC2 autoscaling group allows your EC2 fleet to expand or shrink based on demand. Review the configuration and see if the minimum can be reduced, to meet end user requests, but with a smaller fleet size.

Use Reserved Instances (RI) to lower RDS, Redshift, ElastiCache, and Elasticsearch costs

Follow the recommendations provided in the AWS Cost Explorer RI purchase recommendations, which are based on the use of RDS, Redshift, ElastiCache, and Elasticsearch. Be sure to adjust the parameters to one year. This requires a one-year commitment, but the break-even point is usually seven to nine months.

Apply Savings Plans for computing to reduce EC2, Fargate and Lambda costs.

Follow the recommendations provided in AWS Cost Explorer and make sure that you have chosen the computing option, one year, with no initial options. Once you sign up for Savings Plans, your computer usage will automatically be charged at the prices of the discounted Savings Plans.

The cloud allows you to replace fixed expenses (such as data centers and physical servers) with variable expenses and pay only for IT resources as you use them. For more information on faster cost optimization techniques.

With the help of Compucloud, you can apply these and many other cost-reduction practices.
