How to Run Chaos Tests in a Multi-Cloud Environment

In a blog post by Dan Kelly, the complexities and challenges of implementing chaos tests in multi-cloud environments are explored, particularly in the context of e-commerce systems stressed during peak shopping events like Black Friday and Cyber Monday. Ana Medina, a chaos engineer from Gremlin, highlights the importance of proactively exposing bugs through chaos testing by assuming cloud vendor failures and testing basic functionality, data consistency, and cost implications. The discussion emphasizes that while multi-cloud infrastructure can mitigate outages, it introduces new challenges that require thorough chaos testing to ensure a robust failover strategy. Talks from ESCAPE/19, including those by Dan Papandrea and Spencer Kimball, further elaborate on securing services and handling data across global multi-cloud deployments, underlining the necessity of chaos engineering in verifying multi-cloud strategies.
