Which AWS and Azure concepts should I know?
Cloud platforms provide managed building blocks for compute, storage, databases, networking and operations. AWS and Azure use different service names, but the underlying choices—virtual machine versus managed runtime, object storage versus database, public versus private network—are transferable. Understanding responsibilities is more useful than memorizing a long service list.
How do DNS, load balancers, IAM and secrets fit together?
DNS resolves names to records, load balancers select healthy destinations, IAM controls identities and permissions, and secret managers store sensitive credentials. These components connect an application to users and dependencies without putting all configuration into code. A failure at any layer can look like “the API is down” from the outside.
