Client Overview

Our client is a fast-scaling e-commerce company preparing to expand into a new international market. However, with a growing cloud footprint and limited cost visibility, their AWS monthly spend had escalated to approximately $20,000. To support their expansion without jeopardizing performance or financial efficiency, they engaged Techieonix for a FinOps-led cloud cost optimization initiative.

Problem Statement

The client operated across multiple AWS accounts with little centralized cost governance. Their environment included:

  • Redundant and stale resources still consuming costs
  • Over-provisioned compute and storage services
  • No clear ownership of infrastructure components
  • Manual reporting with no actionable insights
  • Lack of visibility into cost drivers and usage trends

As a result, the high cloud cost became a bottleneck to scaling the business efficiently.

Requirement Gathering

The client aimed to adopt FinOps practices to control and reduce cloud costs while ensuring smooth application, database, and microservice performance.

  • Centralized visibility into cloud spend and resource inventory
  • Spend trend analysis over the last 3 months
  • Identification of waste (stale, idle, over-provisioned resources)
  • Clear mapping of resources to business units or owners
  • Custom automation and dashboards for real-time insights
  • Optimization actions that would not compromise system performance

Our Approach

As specialists in Cloud, DevOps, and FinOps, Techieonix followed a data-driven and automation-first approach:

Cross-Account Resource Inventory

Built a unified inventory across all AWS accounts.

FinOps Spend Trend Analysis

Reviewed 90-day billing data to identify cost anomalies and patterns.

Utilization Audit & Waste Identification

Flagged idle, underused, and misconfigured services using internal scripts.

Cost Ownership & Accountability

Assigned resource ownership to relevant teams for informed decisions—a key FinOps principle.

Automation for Optimization

Developed scripts and tagging logic to streamline future audits.

Visibility via FinOps Dashboard

Created an internal dashboard to offer real-time views of:

  • Cost by service and account
  • Top contributors to spend
  • Status of flagged vs. resolved optimization actions

Key Actions & Features

FinOps Dashboard for Visibility

Built a centralized dashboard showing real-time AWS spend, enabling teams to identify and act on cost trends quickly.

Automated Resource Analysis

Custom automation flagged stale and over-provisioned resources without relying on raw billing data.

Cost Ownership Mapping

Mapped infrastructure to responsible business units to enable cross-functional decision-making and accountability.

Optimization Without Risk

All actions were taken in close collaboration with internal teams to ensure zero downtime and full service continuity.
