Breaking Serverless Things on Purpose: Chaos Engineering in Stateless Environments - Emrah Samdan

Oct 15, 2020 By Gremlin In Gremlin
Serverless enabled us to build highly distributed applications that led to more granular functions and ultimate scalability. However, it also brought the risk of failure from a single microservice to many serverless functions and resources. You might be able to predict and design for certain troublesome issues but there are many, many more that you probably will not be able to easily plan for. How do you build a resilient system under these highly distributed circumstances? The answer is Chaos Engineering: Breaking things on purpose just to experience how the whole system will react.

Chaos Engineering: The Path to Reliability - Kolton Andrus

Oct 15, 2020 By Gremlin In Gremlin
We’re all here for the same purpose: to ensure the systems we build operate reliably. This is a difficult task, one that must balance people, process and technology during difficult conditions. We operate with incomplete information, assessing risks and dealing with emerging issues. We’ve found Chaos Engineering to be a valuable tool in addressing these concerns. Learn from real world examples what works, what doesn’t, and what the future holds.

Identifying Hidden Dependencies - Liz Fong Jones

Oct 15, 2020 By Gremlin In Gremlin
You don't need to write automation or deploy on Kubernetes to gain benefits from resilience engineering! Learn how Honeycomb improved the reliability of our Zookeeper, Kafka, and stateful storage systems through terminating nodes on purpose. We'll discuss the initial manual experiments we ran, the bugs in our automatic replacement tools we uncovered, and what steps we needed to progress towards continuously running the experiments. Today, no node at Honeycomb lives longer than 12 months, and we automatically recycle nodes every week.

Is your microservice a distributed monolith?

Sep 30, 2020 By Andre Newman In Gremlin

Your team has decided to migrate your monolithic application to a microservices architecture. You’ve modularized your business logic, containerized your codebase, allowed your developers to do polyglot programming, replaced function calls with API calls, built a Kubernetes environment, and fine-tuned your deployment strategy. But soon after hitting deploy, you start noticing problems.
