The Challenge
Despite being on an annual commitment plan with Microsoft Azure, 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 Azure usage and uncover actionable savings opportunities. 

Here’s what Karbon did: 

  • Billing Diagnostic & SKU Deep Dive 
    Karbon’s Azure 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 Solution
Kite Finance partnered with Karbon Business, a cloud discount aggregator, to optimize their cloud costs. 

Karbon’s process involved: 

  • One-Click Cloud Bill Analysis 
    The Karbon team ingested Kite’s last 3 months of AWS bills, breaking down spend by service, project, and usage patterns. 

  • Custom Discount Allocation via Partner Network 
     Using Karbon’s partner network, they negotiated a 1-year committed spend plan without any engineering lock-in or billing changes. 

  • Unused Resource Identification 
     Karbon’s team ran optimization checks to identify: 

    • Idle EC2 instances 

    • Overprovisioned RDS clusters 

    • Orphaned EBS volumes 

  • Weekly FinOps Syncs 
    Karbon set up bi-weekly FinOps reviews for continuous savings, anomaly detection, and dashboarding.


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