Cutting Costs and Boosting Scalability
with AWS EKS

Transform client applications for lower costs and higher performance

Cloud: AWS EKS

Responsibility: Project Delivery

Challenge

1. firecaat was working with a client who operates a combination of critical and non-critical applications built on React, Node.js, Java and PHP-based ecommerce & custom solutions.
2. All runs on individual AWS EC2 instances.
3. The applications of each client ran on separate EC2 instances, supported by RDS databases.
4. The setup ensured isolation but it costs expensive.
5. Each new client required new EC2 instances.
6. Without efficient scaling or resource sharing, expenses kept rising.
7. At that time, we needed a more cost-effective and scalable solution.

Motivation

1. The goal of firecaat was to minimize expenses without compromising on isolation, reliability and security.
2. We aimed to build a platform that could scale smoothly with little operational effort.
3. After analysing the case, we settled to rate to AWS EKS (Elastic Kubernetes Service).
4. Our approach was to consolidate applications onto EKS clusters, run critical applications on Reserved and On-Demand EC2 instances.
5. Along with this, using Spot Instances for non-critical applications to reduce the expenses.

Outcome

After six months of hardwork, we were excited to see 50-60% drop in costs. Apart from saving money, migration also enhanced scalability and reliability. Our clients were satisfied and our team could concentrate on innovation rather than managing expenses.
