Seth Eliot, Principal Resilience Architect at Arpio, and former Global Reliability Lead at AWS, joins Corey to discuss cloud resilience. He emphasizes that Multi-AZ setups are typically sufficient, with multi-region configurations only necessary for specific risks. Seth highlights the importance of balancing cost and resilience based on business needs, while cautioning against making resilience a mere checkbox exercise. Together, they explore disaster recovery challenges, noting that many companies fail to account for real-world complexities during testing. Seth also stresses the importance of avoiding control plane dependencies and warns that poorly designed multi-cloud setups can introduce additional risks.

He thrives on helping teams tackle those "make or break" technical, process, or culture challenges—then partners up to solve them. As the Global Reliability Lead for AWS Well-Architected, Seth didn’t just work with customers; he scaled his insights via workshops, presentations, and blog posts, benefiting thousands. Before that, as one of the rare AWS-dedicated Principal Solutions Architects at Amazon.com (yep, not AWS, but the mothership itself), he rolled up his sleeves with engineers to fine-tune the AWS magic powering Amazon.com’s immense stack. Earlier? He led as Principal Engineer for Amazon Fresh and International Tech, and before that, helped bring Prime Video into homes everywhere.
