Cloud Chaos and Microservices Mayhem
summary
Cloud-era costs and coupling bite: a 2017 survey finds ~25% of 16,000 servers doing no useful work, and forgotten test clusters can rack up bills (anecdotal €2,000). The talk argues finops for real-time cost ownership, warns of distributed monolith anti-patterns (bank with a twice-yearly release board), and demonstrates consumer-driven contract testing using Pact with a Java (Open Liberty) backend and JavaScript frontend where a torso/stomach JSON naming mismatch is detected and fixed by provider-side contract verification.
