Compare production deployment strategies for SaaS apps: in-place, rolling, blue-green, canary, health gates, rollback, capacity, and database compatibility.
Learn when SaaS apps need background workers and task queues, including retries, idempotency, dead-letter jobs, worker sizing, scaling, and monitoring.
Plan startup cloud infrastructure from MVP to production: compute, data, cost, reliability, launch readiness, diligence, and Kubernetes decisions.
Plan SaaS architecture from a single VM to separated databases, state, storage, multiple app nodes, private networking, deployment, and recovery.
Evaluate VPS application hosting by workload, resources, state, background jobs, recovery, scaling, and when one VM or another platform fits.
Use this production VPS checklist to validate SaaS capacity, access, traffic paths, storage, backups, monitoring, restore testing, and scaling decisions before launch.
Learn when to separate app and database servers for SaaS, compare managed vs self-hosted paths, and plan networking, recovery, cost, and migration.
Plan Redis and Valkey for SaaS caching, queues, sessions, rate limiting, persistence, and recovery, then choose managed Valkey or self-hosting.
Build a database backup strategy for SaaS apps using RPO, RTO, point-in-time recovery, retention, isolation, disaster recovery, and tested restores.
Understand shared hosting to cloud VM migration for SaaS teams, including architecture, data sync, DNS cutover, rollback, security, and recovery planning.
Understand PostgreSQL connection pooling, PgBouncer modes, pool sizing, max_connections, and how SaaS teams prevent connection storms in production.
Understand PostgreSQL for SaaS apps across sizing, connections, pooling, backups, high availability, and managed vs self-hosted production ownership.
Decide when a small SaaS should use one database or multiple databases across workloads, services, tenants, recovery boundaries, and managed database roles.
Compare MySQL hosting across managed MySQL and self-hosted MySQL, including cost, connections, backups, PITR, HA, recovery, and operational ownership.
Compare Postgres hosting for SaaS across managed PostgreSQL and self-hosted PostgreSQL, including cost, connections, backups, HA, recovery, and operational ownership.
Compare PostgreSQL vs MySQL across performance, JSON, transactions, extensions, replication, use cases, migration, and managed hosting to choose the right database.
Learn cloud VM vs app platform trade-offs for startups, including control, deployment speed, cost, scaling, storage, and when each model fits production.
Decide when app uploads should stay on VM disk or move to object storage, including S3 upload patterns, scaling, security, multi-server access, migration, and recovery.
Learn how SaaS gross margin connects revenue, COGS, cloud allocation, and infrastructure cost per customer for clearer pricing and unit economics decisions.
Compare SQL vs NoSQL across relational, document, and key-value models, including data modeling, performance, scaling, SaaS use cases, and operations.
Build a stage-based SaaS infrastructure budget from MVP to Series A across compute, databases, storage, environments, recovery, and operating cost.
Compare microservices vs monolith for small teams, including modular monoliths, scaling, ownership, data boundaries, operational cost, and migration signals.
Learn how object storage events trigger serverless file processing, with prefix filters, idempotency, retries, status tracking, security, and worker trade-offs.
Learn how portable serverless handlers reduce Lambda lock-in, keep functions easier to move, and support standard runtimes on Raff Functions.
Learn when to use serverless functions for webhooks, when VMs are better, and how to design webhook retries, logs, security, and storage.
Learn serverless function pricing: memory GB-seconds, active CPU, requests, egress, free tiers, warm capacity, cost estimation, and when a VM may be cheaper.
Compare serverless functions vs VMs for small teams: workload fit, cost shape, state, scaling, operations, recovery, and when a mixed architecture works best.
Run a SaaS audit to find unused spend, consolidate subscriptions, and decide when a small business should keep SaaS, use a managed service, or self-host.
Decide when a SaaS app should stay on one VM or separate its application, database, workers, files, cache, and traffic routing across multiple systems.
