Arthimpact Finserve Private Limited  is a Fintech company based out of Mumbai India that processes and disburses loan to customers 100% electronically through web application.

Challenge

Arthimpact Finserve Private Limited uses AWS for hosting their web application. Their cloud infrastructure cost was over 16,000USD/month that they believed their work load 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 on how to reduce their AWS bills.

As a technology startup they cannot spend too much on AWS infrastructure cost that would reduce their business profit that may lead to 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 bills to maximum extent without compromising the performance of their application as well as their business revenue.

Analysis

Easydeploy Technologies Pvt Ltd carried out the following steps before we proceeded to suggest them the solutions 

• We analyzed the cost and 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 EC2 instances and RDS instances
• We analyzed and found that they are using a lot of unwanted 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 EC2 and snapshots of RDS were present in their account
• We analyzed and found there are huge data present in S3 buckets are not Enabled with 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 ECR are not Enabled with lifecycle policy
• We analyzed the NAT Gateway data charges and saw that there was no private link between S3 and ECR repository.

We listed out all this details to them and after getting the approval from them we did the following

• 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
