PostgreSQL performance tuning for SaaS teams: query plans, indexes, vacuum, statistics, locks, connection pressure, and capacity decisions.
Understand PostgreSQL connection pooling, PgBouncer modes, pool sizing, max_connections, and how SaaS teams prevent connection storms in production.
Understand database monitoring for small teams across slow queries, connections, locks, capacity, replication lag, backups, restore evidence, and alert ownership.
Compare shared vs dedicated vCPU by CPU predictability, sustained load, latency, workload fit, and when General Purpose or CPU-Optimized makes sense.
Size VPS RAM using working set, MemAvailable, swap, OOM events, Docker, databases, and workload evidence instead of fixed utilization percentages.
Compare 2 vCPU vs 4 vCPU cloud VMs using CPU pressure, concurrency, latency, queues, and workload evidence instead of environment labels.
Diagnose cloud server performance bottlenecks across CPU, memory, disk I/O, network, databases, and dependencies before resizing or scaling.
Learn VM sizing by matching CPU, RAM, storage, network, and operating headroom to real workload behavior, then validate the choice with production metrics.
Plan VM autoscaling with demand signals, capacity limits, warm-up, stabilization, readiness, safe scale-in, dependency guardrails, testing, and cost controls.
Learn how to choose a VPS provider with a 10-point framework for performance, support, pricing, backups, security, location, scalability, and lock-in.
Compare the best VPS hosting providers by performance, support, pricing, locations, backups, and lock-in using a transparent decision framework.
Learn how to benchmark VPS CPU, NVMe storage, network, consistency, and price-performance without being misled by one synthetic score.
Compare VPS and dedicated servers by cost, performance, isolation, scaling, recovery, and the workload signals that justify upgrading to physical hardware.
Learn Docker volumes vs bind mounts by comparing persistence, portability, security, and operations. Choose the right storage model for production containers
Build application observability for a small team with practical metrics, structured logs, distributed tracing, SLI, SLO, alerting, and telemetry cost decisions.
Learn single-server vs multi-server architecture for growing apps. Compare cost, complexity, scaling signals, and when to split workloads on Raff.
