Compare IPv4, IPv6, and dual-stack networking for cloud servers, including DNS, firewalls, application binding, monitoring, and migration planning.
Compare PostgreSQL replication, backups, WAL recovery, and snapshots by the failure modes each protects and the recovery gaps each leaves.
Learn when Docker Compose is enough and when small teams should move to Kubernetes, with a Raff path from VM, database, storage, and worker roles.
Compare environment variables, vaults, and managed secret stores for cloud apps. Learn when each fits, how to rotate secrets, reduce exposure, and avoid secret sprawl.
Learn S3-compatible object storage use cases for developers, when to use it, and how to match backups, media, logs, and assets to Raff storage.
Learn how to choose a U.S. cloud server for latency and compliance. Compare region placement, traffic paths, and controls that matter for safer deployments.
Compare stateful and stateless applications, decide where application state should live, and prepare sessions, files, jobs, databases, scaling, deployment, and recovery.
Learn single-server vs multi-server architecture for growing apps. Compare cost, complexity, scaling signals, and when to split workloads on Raff.
