Embracing Chaos: Harnessing the Power of Chaos Testing for Resilient Systems

  • Testing is essential to ensure that your software application performs as expected. No doubt about it. But even if your application runs smoothly in a testing environment, unexpected incidents can occur in production, such as a crashed database or a lost connection to a third-party service. To ensure your application can handle such incidents and minimize their impact, you need to incorporate chaos testing into your delivery process. In this workshop, we will start with a brief introduction to k6 for backend performance testing and we’ll explore how to implement chaos testing using k6 for two backend services, to help you ensure the resilience of your application.

Liberate your data using Redis Stream and Go

  • Redis is an in-memory database popular for many use cases, such as content caching, session stores, real-time analytics, message broker and data stream needs. Since version 5.0 of Redis a new data structure, Redis Streams, dedicated to managing streams has been introduced. Using Redis Streams, anyone can do a lot more than what was possible with Pub/Sub, Lists or Sorted Sets in the data stream domain. In this all-hands session, we’ll walk you through the basics of how to use Redis Streams, how consumer groups work, and finally show a working application using Go that uses Redis Streams.
