We knew Chaos Engineering was in high demand when we first launched the Gremlin certifications in 2021. But we had no idea our Chaos Engineering certification programs would be such a success. There’s a reason: the market is looking for professionals who know how to wield Chaos Engineering well, and Gremlin's certification has become the gold-standard to learn the principles of Chaos Engineering and demonstrate proficiency.

Ensuring software availability is essential for any SaaS company—including Gremlin. To do that, our teams need to identify the reliability risks hiding in our systems. That’s why our development, platform, and SRE teams use Gremlin regularly to perform Chaos Engineering experiments, run reliability tests, and track the reliability of our systems against our standards. Along the way they’ve picked up a thing or two about how to find and fix reliability risks with Gremlin.

In today's fast-paced technological landscape, ensuring the resilience and dependability of systems is crucial. This is where Chaos Engineering comes in, transforming how organizations approach system testing and fortification. Chaos Engineering helps find vulnerabilities that could go undetected under normal circumstances by purposefully introducing controlled interruptions and failures.

Building momentum for a reliability program can be tough. Improving reliability takes time, effort, and resources. But when everything from launching new features to improving security demands those same resources, it can be a struggle to get the buy-in you need to address reliability risks. And it makes sense! If a team spends time patching a known security bug or creating a new feature, they have a clear demonstration of the value created.

We've seen a tremendous transition in the architecture of our systems over the years, from basic, linear systems to increasingly sophisticated, non-linear systems. We've moved away from monolithic programs, where a single person could comprehend the entire operation of a system, and toward a distributed world dominated by a microservices design.

Incident response has been the cornerstone of reliability for decades. From digging in the server logs to navigating modern observability dashboards, responding quickly to incidents and outages is a big part of minimizing downtime. And it should be! When something breaks, your team should move as quickly as possible to address and repair the problem.

With so many Chaos Engineering tools available, it’s no surprise that SRE and platform leaders are doing their homework when choosing a platform to help them build and scale their Chaos Engineering programs. But like anything else you can research on the internet, there’s a lot of noise and hype that you need to wade through. Gremlin works with Reliability Engineering teams at hundreds of companies with the most sensitive workloads—and has since 2016.

Last week, over five hundred SREs gathered in Santa Clara to share the latest research, tips, tricks, best practices, and more for site reliability engineering. They were joined by some of the biggest names in the reliability space. And, yes, Gremlin was there to answer any and all questions about chaos engineering and proactive reliability. After three days of great conversations and insightful talk, let’s take a look at some of the themes we heard weaving through SRECon.

In January of 2023, Google released its infrastructure reliability guide, which provides guidelines on how to build high-availability applications in Google Cloud. While it's written for Google Cloud, it provides some excellent general-purpose information on how to architect reliable applications on any cloud provider, including: In this blog, we'll explain each of these factors and how you can use Gremlin to ensure you're meeting your reliability requirements.
