# Stay reliable — even when traffic isn't.

> Handle traffic spikes, retries, bots, AI bursts and real-world volatility.
> Protect your API before requests reach your origin with Zuplo's managed

## Traffic volatility — handled before it reaches your origin.

### Absorb spikes before they hit your API.

Every request is evaluated against rate limits, quotas, and caching policies
before forwarding. Your origin receives controlled, intentional traffic — not
raw spikes.

### Isolate consumers. Protect everyone else.

One client's aggressive traffic doesn't affect others. Policies are scoped per
API key, route, plan, or custom attribute — enforcement happens at the gateway,
not your backend.

### Prevent cascading failures at the edge.

Retry policies, timeouts, and circuit breaking let you define how the gateway
behaves under stress — before failures compound into an outage.

### Automatic failover across global regions.

Distributed execution across Cloudflare's global network. Regional disruptions
are handled automatically — policy enforcement and API availability continue
uninterrupted.

## Scale without overprovisioning.

Traditional scaling requires forecasting peak capacity and maintaining idle
headroom. Zuplo runs as a managed gateway — it scales automatically, and you pay
for behavior defined, not infrastructure reserved.

**You define behavior. The platform handles execution.**

|                     | Traditional Scaling         | Zuplo                        |
| ------------------- | --------------------------- | ---------------------------- |
| Capacity management | Provision + autoscale rules | Managed — scales with demand |
| Idle infrastructure | Billed during off-peak      | None                         |
| Spike handling      | Reactive (may lag)          | Immediate, edge-enforced     |
| Cost model          | Infrastructure reserved     | Behavior defined             |

## Advanced reliability controls.

For teams with stricter requirements.

- **Environment-specific deployments** — Separate dev, staging, and production
  gateways with isolated policies and traffic per environment.
- **Regional control** — Pin your gateway to specific regions to meet data
  residency and compliance requirements.
- **Dedicated infrastructure** — Isolated execution environment — no shared
  resources, no noisy-neighbor effects.
- **Capacity guarantees** — Committed throughput and burst headroom backed by
  contractual SLA-level guarantees.

## Frequently asked questions

**How does Zuplo protect my API from traffic spikes without infrastructure
changes?**

Zuplo deploys rate limiting, request buffering, and surge absorption policies at
the edge — before traffic reaches your origin. When a spike occurs, the gateway
enforces configured thresholds automatically. Your backend sees controlled,
intentional traffic regardless of how chaotic the inbound load is.

**Does Zuplo support per-consumer rate limiting?**

Yes. Rate limits in Zuplo can be scoped per API key, per user, per plan, per
route, or by any custom attribute in the request. One consumer's burst traffic
is isolated and throttled without affecting any other consumer. This isolation
is enforced at the gateway, not in your backend code.

**Can Zuplo protect against retry storms and cascading failures?**

Yes. Zuplo supports configurable retry policies, circuit breaking, and timeout
enforcement. When a backend becomes unhealthy, the gateway can stop forwarding
requests immediately — preventing the retry amplification that typically causes
cascading outages. Policies are defined in code and deployed globally in
seconds.

**How does Zuplo handle failover across regions?**

Zuplo runs on Cloudflare's global network across 300+ data centers. If a region
becomes unhealthy, traffic is automatically routed to the nearest available
location. Policy enforcement and API availability continue uninterrupted —
there's no manual intervention required and no downtime for your consumers.

**How does Zuplo scale to handle millions of requests?**

Zuplo is a managed gateway — there are no servers to provision, no autoscaling
rules to configure, and no capacity to forecast. The platform scales elastically
with demand. You define policies in TypeScript and JSON; Zuplo handles execution
across its distributed edge infrastructure.

**What SLAs does Zuplo offer for high-availability deployments?**

Builder plans include a 99.5% uptime SLA. Enterprise plans with dedicated
infrastructure offer up to 99.999% SLA with committed throughput, burst
headroom, and dedicated support channels. Contact our team to discuss
requirements.
