Situation

As a cornerstone of the American financial industry and the largest credit ratings agency, this client requires nearly 100% availability of its systems with response times of less than a second.

With over 500,000 daily logins and 1.5 million users worldwide, it was critical to the client’s business operations that it achieve the following objectives:

  • 99.995% availability
  • <1 sec. AuthN response
  • Minimized performance issues at production go-live
  • Multiple runs of performance and load testing
  • Load Testing of each metric-capturing component
  • Understanding of scalability of cloud infrastructure in terms of newer sites and regions going live

AST’s team met and exceeded the client’s mandate to build a robust identity and access management system in cloud. The team simulated the complex endurance and stress test scenarios for 10x the current user load; the rigor in complex testing scenarios ensured that worldwide users have secure access to critical applications with no disruptions, despite any type of catastrophic failures in any region. Kudos to the AST team, who worked with Oracle, AWS, and the client to deliver a top-notch security system operating at scale and 99.999 availability!
