Overview

PayServ aims to unlock seamless shopping and effortless transactions through its digital wallets, ePOS systems, and ecommerce payment infrastructure. As the platform scaled across merchants and consumers, AWS infrastructure costs became increasingly complex—and expensive.

The Challenge
Despite being on an annual commitment plan with AWS, PayServ noticed: 

  • Suboptimal workload distribution across regions 

  • Unused or redundant App Services and VMs 

  • No dynamic scaling policies on key workloads 

  • A lack of visibility into cost per customer or feature 


Their monthly cloud cost had grown by 40% in 12 months. While they didn’t want to migrate or re-architect anything, the team needed to optimize spend without disrupting operations or customer experience.


The Solution
PayServ brought in Karbon Business to conduct a full audit of their AWS usage and uncover actionable savings opportunities.

Here’s what Karbon did: 

  • Billing Diagnostic & SKU Deep Dive 
    Karbon’s AWS specialists broke down usage by SKU and region, identifying multiple opportunities to shift to more cost-effective plans. 

  • Discount Bundling via Partner Network 
     Using Karbon’s CSP partner network, they secured volume-based discounts typically reserved for enterprise-scale clients. 

  • Zombie Resource Cleanup 
     The team identified idle VMs, duplicate services, and unused storage—then helped PayServ decommission them safely. 

  • Cost Allocation & Chargeback Mapping 
     Tagging frameworks were implemented to map spend to departments and products, driving cost accountability internally.


The Results
In just 4 weeks, PayServ saw significant cost improvements:
