In the premiere episode of Cloud Computing with Fexingo, Lucas and Luna drill into one specific number: the list price of a single AWS EC2 instance type, the m5.xlarge, which has sat at $0.192 per hour unchanged for years. They trace how that apparent stability masks a labyrinth of reserved instances, spot markets, and savings plans that can swing costs by 60 percent or more. Using a real-world startup case — a fintech that cut its AWS bill by 35 percent without migrating — they unpack the economics of cloud elasticity, the lock-in dynamics of committed-use discounts, and why most cloud bills go unread. This episode sets the tone for the show: one concrete metric, one sharp case, and the infrastructure decisions that actually move the needle.
