How we reduced AWS Cloud bills of Arthimpact Finserv by 65%.

Arthimpact Finserve Private Limited is a Fintech company based out of Mumbai India that processes and disburses loans to customers 100% electronically through a web application. We identified the challenges that led to the increase in AWS costs, analyzed them, and devised a solution to decrease their AWS bill. Let’s dive into it.

Challenge

Arthimpact Finserve Private Limited uses AWS for hosting its web application. Their cloud infrastructure cost was over 16,000USD/month and they believed their workload should not cost this much, their in-house team who is managing their AWS architecture was not qualified enough to manage the complexity of their environment hence they were not sure how to reduce their AWS Cost.

As a technology startup, they cannot spend too much on AWS infrastructure costs that would reduce their business profit that may lead to a cash crunch, they were in a dire situation to mitigate this issue so that they can concentrate on their applications development which will, in turn, help them to get a lot of clients. They contacted EasyDeploy seeking help to reduce their AWS Cost to a maximum extent without compromising the performance of their application as well as their business revenue.

Analysis

To Reduce AWS Costs we an expert AWS Consulting Partner carry out the following steps before we proceeded to suggest them the solutions 

• We analyzed the AWS cost and its usage reports for the past 3 months and  have created a spreadsheet of charges for each of the AWS service
• We analyzed the CPU usage and Memory utilization details of all the AWS EC2 and RDS instances
• We analyzed and found that they are using a lot of unwanted AWS EC2 instances
• We analyzed and found that they haven’t utilized the Reserved instance feature provided by AWS
• We analyzed and found that a lot of old AMIs of AWS EC2 and snapshots of AWS RDS were present in their account
• We analyzed and found there are huge data present in AWS S3 buckets that are not Enabled with a lifecycle policy
•  We analyzed and found Cloudwatch logs are not enabled with any retention policy to expire the old and unwanted logs
• We analyzed and found ECRs are not Enabled with a lifecycle policy
• We analyzed the NAT Gateway data charges and saw that there was no private link between AWS S3 and ECR repository.

Solution

We listed out all these details to the client after getting approval from them. We optimized their AWS Cost through the following process:

• Removed the unwanted EC2 instances
• Resized the required EC2 instance according to their current usage
• Purchased Reserved instances for all the required EC2 and RDS instances
• Removed the old AMI images of EC2 and snapshots of RDS
• We have set the RDS snapshots only with 15 days of retention as per the Customer’s requirement
• We have set the EC2 AMI only with 30 days of retention as per the Customer’s requirement
• We have set the Cloudwatch logs retention for 30 days
• We removed the unwanted data from AWS S3
• We have set the lifecycle policy for the ECR images in order to remove a large count of untagged images and also for retaining only 30 images
• We enabled a Private link to save NAT gateway bandwidth charges, as mentioned in the link – Save NAT Gateway Bandwidth charges
