Scaling Prep Security Checklist: 14 Items Before Rapid Growth

January 2026Launch Security

TL;DR

Scaling amplifies both good and bad patterns. Before rapid growth, ensure your infrastructure can scale horizontally, security controls work at volume, logging won't overwhelm storage, and your team has runbooks for common incidents. Fix architectural issues before they become 10x harder.

Infrastructure Scaling 5

Horizontal scaling worksCan add more instances without code changes.

Database scaling plannedRead replicas, sharding strategy, or managed scaling.

Session handling is statelessSessions work across multiple instances.

File storage is centralizedUploads work across instances (S3, etc.).

Background jobs are distributedJob queues work across multiple workers.

Security at Scale 5

Rate limiting scalesWorks correctly across multiple instances.

Auth doesn't bottleneckAuth service can handle increased load.

Secrets management centralizedSecrets work across all instances consistently.

Security logging scalesLog aggregation handles increased volume.

Encryption doesn't bottleneckTLS termination handles traffic increase.

Operational Readiness 4

Runbooks documentedCommon issues have documented responses.

Alerting thresholds adjustedAlerts scale with expected growth.

Cost monitoring in placeTrack spend as you scale to avoid surprises.

Capacity planning doneKnow your limits before you hit them.

When should I start preparing for scale?

When you see consistent growth or before planned events (launches, press, marketing campaigns). It's much easier to fix architectural issues at 1,000 users than at 100,000.

What's the most common scaling security issue?

Rate limiting that doesn't work across instances. Each instance thinks it's the only one, so effective rate limits multiply by instance count. Use centralized rate limiting (Redis, etc.).

Should I scale before I need to?

Prepare to scale, don't pre-scale. Have the ability to scale quickly (auto-scaling, horizontal architecture) but don't pay for capacity you don't need yet.
