Reducing 3rd party content risk with Real User Monitoring


Published on

Trusting 3rd party content providers without full visibility puts your web and mobile business at risk with single points of failure (SPOF), outages and serious performance bottlenecks outside your control. Real User Monitoring (RUM) empowers you to set appropriate Service Level Agreements (SLAs) and delivers indisputable facts to keep your providers honest. But, you also need to know what to expect.

In this webinar you’ll learn:

Common third-party services and how to measure them with RUM
Using synthetic monitoring services to know what to expect
Understanding and testing for SPOF
Setting reality-based SLAs with your providers
Information sharing for full accountability

Join Web Performance veteran Cliff Crocker for this free webinar on a hot issue.
