DevOps & Cloud Cost Optimisation
Rightsized AWS infrastructure using Compute Optimizer + Spot instances, migrated to Graviton2, and implemented auto-scaling — saving $180K/year in cloud spend.

The Challenge
An e-commerce business was experiencing massive traffic swings, causing CPU spikes and database timeouts. To prevent outages, they over-provisioned their cloud resources, resulting in astronomical cloud bills with an average server utilization of less than 15%.
Our Solution
We conducted a thorough audit of their AWS architecture. We restructured their EKS clusters to utilize AWS Graviton2 processors (providing better price-performance), set up fine-grained Kubernetes Horizontal Pod Autoscaling (HPA), and migrated staging/development loads to AWS Spot instances.
Interactive System Architecture
Infrastructure Audit
Analyzed billing alerts, idle resources, and container resource limits.
Graviton Migration
Rebuilt container images to support ARM64 architecture and migrated workloads.
Autoscaling Policies
Configured cluster autoscalers to match traffic changes dynamically.

The Business Impact
Cut the annual cloud hosting expenditure by 43%, amounting to over $180,000 in savings. Despite the cost cuts, application response latency dropped by 18% due to the efficiency of Graviton2 processors.
