Learn Redis cache strategy for SaaS apps, including queues, sessions, persistence, Valkey compatibility, and managed versus self-hosted deployment decisions.
Learn VPS database hosting for small teams: when to self-host PostgreSQL, MySQL, MariaDB, or MongoDB and when a managed database is the better operating model.
Understand a database migration checklist for managed databases covering target validation, backups, synchronization, cutover, rollback, and recovery.
Understand database monitoring for small teams across slow queries, connections, locks, capacity, replication lag, backups, restore evidence, and alert ownership.
Understand database reliability for small teams across monitoring, failover, backups, PITR, restore testing, capacity, and managed-service ownership.
Understand when a small SaaS team should use one database or multiple databases across services, tenants, workloads, recovery boundaries, and managed database roles.
Plan zero-downtime database migrations with expand-contract, staged backfills, managed database cutovers, rollback, and engine-specific PostgreSQL or MySQL controls.
Learn Redis hosting choices: compare managed Valkey with self-hosted Redis across control, persistence, eviction, recovery, cost, and operations.
Compare managed database vs self-hosted across cost, control, backups, recovery, scaling, security, and operations to choose the right model.
Compare MySQL vs PostgreSQL vs MongoDB by data model, transactions, performance, scaling, operations, and hosting to choose the right database.
Learn PostgreSQL vs MySQL differences in SQL, JSON, performance, operations, and hosting so your team can choose the database that fits its workload.
Learn MySQL hosting for production apps: compare managed and self-hosted MySQL, size connections and storage, plan recovery, and evaluate Raff’s managed path.
Learn Postgres hosting for SaaS: compare managed and self-hosted PostgreSQL, size connections and storage, plan recovery, and test Raff’s free database tier.
Learn when to separate app and database servers for SaaS, compare managed vs self-hosted paths, and plan networking, recovery, cost, and migration.
Learn database backup strategy for SaaS apps using RPO, RTO, point-in-time recovery, restore testing, retention, and separate recovery layers for production.
Learn database storage on block volumes, including disk layout, IOPS and latency monitoring, capacity planning, backups, and recovery decisions.
Understand when block storage volumes fit databases, containers, and application data, including sizing, backups, recovery, and when object storage is better.
Learn how block storage vs local disk differs in lifecycle, performance, persistence, backups, database fit, and recovery planning for cloud workloads.
Learn a database incident runbook for connection exhaustion, disk pressure, failover, recovery validation, communication, and post-incident action.
Learn MySQL vs MariaDB for production apps: compare compatibility, hosting, backups, replication, monitoring, upgrades, and managed or self-hosted operations.
Learn when not to use a VPS, the main VPS limitations, and when shared hosting, an app platform, managed database, serverless, Kubernetes, dedicated hardware, or object storage fits better.
Learn what a VPS is used for, which workloads fit virtual servers, and when websites, apps, databases, Docker, automation, or Windows need another hosting model.
