In this episode of CODE&CLOUD, Rauno De Pasquale (CTO at Newesis) sits down with Luca Mezzalira (Serverless Specialist Solutions Architect AWS and author of Building Micro-Frontends from O’Reilly) to unpack how to tackle complexity in modern systems: DevOps, cloud, microservices, micro-frontends, governance and team organization.Starting from the “paradox” of modern architecture—greater agility promised, yet new distributed complexity—Luca shares pragmatic ways to decide when and how to split systems, how to reduce teams’ cognitive load, and what the architect’s role really is today: less “master builder,” more coach/enabler who asks the right questions, defines reusable patterns, and navigates the trade-offs across technology, organization, and business.What you’ll learnHow to evaluate whether microservices/micro-frontends add value in your contextWhy governance, observability, and security are not afterthoughtsHeuristics for defining boundaries (DDD, event storming, rate of change)Reducing cognitive load with blueprints, platform engineering, and security championsThe architect as a force multiplier across engineering, culture, and org designSynchronous vs. asynchronous choices, batching, and cost-aware resilienceSuggested chapters00:00 Intro01:20 Who is Luca Mezzalira04:10 The paradox of modern architecture10:35 How “micro” should it be?
