Plan vertical and horizontal scaling, scale-to-zero, immutable revisions, health-gated releases, rollback, capacity headroom, and production release safety on App Platforms.
Learn how to scale beyond one Docker Compose host with role separation, multiple app VMs, load balancing, shared state, Swarm, and a clean path to orchestration.
Learn how serverless cold starts, concurrency, scale-to-zero, warm capacity, and traffic bursts affect latency, autoscaling, and production function design.
Understand Kubernetes autoscaling with HPA, node scaling, resource requests, scale-to-zero, stabilization, scheduling, and worker cost boundaries.
Learn when Kubernetes node pools make sense, how labels, affinity, taints, autoscaling, failure capacity, and worker shapes affect workload placement.
Compare horizontal vs vertical scaling and scale up vs scale out for cloud applications, including examples, state, databases, availability, and operational trade-offs.
Learn load balancing: L4 vs L7, health checks, connection draining, failover, state, TLS, private backends, and when multi-node applications need traffic distribution.
Learn cloud autoscaling for VMs: plan autoscaling policies, scale-out and scale-in signals, capacity limits, warm-up, readiness, dependency guardrails, and safe removal.
Plan WebSocket hosting for real-time apps. Compare one-VM and multi-node designs, size persistent connections, handle load balancing, reliability, security, and cost.
Decide when a SaaS app should stay on one VM or separate its application, database, workers, files, cache, and traffic routing across multiple systems.
Docker Compose vs Kubernetes for small teams: compare production fit, migration triggers, operational cost, readiness, and a staged Raff infrastructure path.
Stateful vs stateless explained with application examples, architecture, load balancing, sessions, databases, scaling, deployment, and recovery trade-offs.
Compare single server vs multi-server architecture, including when to split databases and workers, when to add app nodes, and when scaling up is still the simpler choice.
