The company Crisp transitioned from multiple open-source monitoring tools to a single observability tool, New Relic, due to complexity and cost concerns. They initially chose an observability provider based on its pricing plan, but were still stuck with multiple tools after a year. After revisiting their strategy, they switched to New Relic, which offered a predictable pricing model, streamlined operations, and improved the return on investment from their monitoring tool. With New Relic, they were able to onboard new engineers in six months, turning their technical operations team into a center of excellence, and improve mean time to recovery (MTTR) by 95%. The company aims to further optimize their workflows with business-as-usual ratios and TerraForm.
