## What the story says

Burst SMS uses Harness CI and CD to build and deploy 30 services plus its monolith during application modernization, and uses the Cloud Cost Management module to shut down test environments outside operational hours and to detect and report anomalous cloud charges. It also uses blue/green deployments for fast recovery and Slack notifications routed to impacted teams.

Summary written by usedby from the source page, in English. The figures are those of Harness and Burst SMS, not ours.

> Moving to Harness’s build infrastructure for Continuous Integration (CI) also delivered significant cost savings. Previously, Burst SMS had to maintain their own cluster for builds and related activities. The cloud costs alone were $110,000 per year. By moving to Harness CI, builds accelerated and those infrastructure costs were cut by 76%, saving over $80,000 annually.

- **66%**: “This led to a 66% reduction in environment-related costs, contributing to notable financial savings.”
- **$80,000**: “By moving to Harness CI, builds accelerated and those infrastructure costs were cut by 76%, saving over $80,000 annually.”
- **96%**: “Now, with blue/green deployments, that’s down to under five minutes, a 96% improvement.”
- **30 services**: “Harness was now the backbone for building and deploying 30 services, not just monolith deploys.”

> My CEO was next to me when an update brought our whole service down. He was shocked at how calm I was. Using Harness, we had everything back up in a couple of minutes. No harm done.
