The concepts from earlier chapters don't live in isolation — they assemble into real systems. This chapter shows how organizations combine those pieces: choosing managed over DIY, designing cloud-native, tracing a real web application end to end, migrating from a data center, and reaching for AI, big data, and IoT.
5 topics
The earlier chapters gave you the building blocks: virtual machines, containers, managed databases, networking, security, scaling, and pricing. Each piece made sense on its own. Now it's time to see how they fit together in practice — how the cloud is actually used by teams, products, and organizations every day.
Five topics complete the picture. First, the single most repeated decision in the cloud — managed versus do-it-yourself. Then the cloud-native mindset that shapes how modern systems are designed. Then a walk through a real web application, naming every building block in its place. Then the vocabulary of cloud migration. Finally, a tour of the higher-level services — AI, big data, and IoT — that sit on top of it all.
