Recreating 3 Common Outages with Gremlin Scenarios

About this webinar

In October of 2016, large swathes of the internet were knocked offline. The cause, as we would eventually learn, was a distributed denial-of-service (DDoS) attack against the DNS provider, Dyn. Many of the internet’s most popular sites that relied on Dyn experienced extended downtime, resulting in a significant impact on revenue, engineering velocity, and brand reputation.

Since the Dyn outage, many major services have built-in redundancy around their DNS provider, allowing them to gracefully failover to a backup service should the primary provider become unavailable.

This is just one example of a failure scenario that caused widespread outages. However, there are other more common scenarios that can cause problems.

You'll walk away understanding how Gremlin can be used to recreate complex failure conditions and proactively prepare your systems to withstand them. You’ll also have the opportunity to have your questions answered by our experts during our Q&A segment.

Agenda

• In this live session, we will introduce 3 failure scenarios that can cause downtime, ranging from simple to complex: autoscaling errors, unreliable networks, and DNS outages.
• You'll see real-world examples of incidents caused by these failure scenarios.
• We will demonstrate how you can recreate these failure conditions and test your systems for resilience against them using Gremlin’s new Recommended Scenarios.
• Finally, you will get a framework for building your own Custom Scenarios specific to your use case.
