Case Study: Burst SMS achieves 66% cost savings and faster deployments with Harness

Burst SMS accelerates application modernization with Harness

Burst SMS, an SMS marketing technology company, needed to modernize a monolithic PHP application so it could scale and support growth. After a failed rewrite attempt, the team adopted a strangler-pattern approach, but the added complexity made deployments and cloud spending harder to manage. To address this, Burst SMS turned to Harness, using its Continuous Integration, Continuous Delivery/GitOps, and Cloud Cost Management capabilities.

With Harness, Burst SMS built and deployed 30 services more efficiently, automated shutdown of test environments, and cut environment-related costs by 66%. Moving builds to Harness CI reduced infrastructure costs by 76%, saving over $80,000 annually, while blue/green deployments helped reduce outage recovery time from two hours to under five minutes. Harness also improved alert routing and reporting, giving Burst SMS better visibility, faster incident response, and a smoother modernization path.
