Modernizing with a Microservice Architecture

After modernizing its applications in the AWS cloud, Vonage, a global Global Cloud Communications provider, had difficulty detecting and troubleshooting problems in its new microservice architecture. 

See how Vonage reduces troubleshooting time and deploys features 2x faster with Epsagon in this AWS webinar

Vonage wanted to resolve application issues quickly and increase developer velocity in order to deploy new business services within its product offerings. The company turned to Epsagon to gain applied observability into its microservice workloads—serverless and containers. Using Epsagon, Vonage was able to decrease MTTR of issues by 25% in the first year and deploy new features 2x faster, while saving significantly on costs from runaway functions.

“Vonage reduced the troubleshooting time of its business-critical applications and deployed features 2x faster with Epsagon.”

Business Challenges

  • Complex architecture—thousands of functions and multiple AWS services 
  • Spikes in workloads daily—peaks equal billions of invocations/month
  • Unpredictable startup times for functions 
  • Difficult to test before deployment
  • Highly manual log analysis 
  • Slow response time to production incidents 
  • Hidden costs with runaway functions 
  • Hard to pinpoint problems in edge cases


  • Visualize the architecture & see everything in production
  • Use in every phase of production from testing to deployment
  • Fully automated from setup in< 5 minutes to issue resolution
  • Auto correlates metrics, logs, traces and payloads for rapid MTTD/MTTR
  • Fix issues in seconds and minutes – not days & hours
  • Leverage cost-monitoring for serverless control
  • Increases developer velocity and new service creation
  • Reduces troubleshooting time up to 95%
