Multi-tier cache
Edge and shield layers reduce avoidable origin fetches while preserving explicit invalidation and TTL control.
GLOBAL CONTENT DELIVERY
A CDN designed around cache control, origin protection and route quality.
BitActive Content Delivery Network combines Anycast ingress, multi-tier caching, origin shielding and request-level controls for static objects, software distribution and high-volume media delivery.

01 / CLIENTREQUEST
Traffic or control enters a defined service boundary.

Policy and placement are evaluated against current state.

The workload is processed by the appropriate infrastructure layer.

Telemetry is preserved so the path can be explained operationally.
01 / OPERATING MODEL
Infrastructure decisions stay visible.
BitActive treats content delivery network as part of an end-to-end infrastructure path rather than as an isolated product. The design starts with where traffic enters the platform, how the resource is reached over private and public networks, what state is maintained, and which failure domains must remain independent. This approach reflects twelve years of operating infrastructure for production workloads: capacity, route quality, failure handling and observability are considered together instead of being delegated to separate layers with no shared context.
Configuration is intended to remain explicit and reviewable. For Content Delivery Network, resource sizing and topology are selected around the workload rather than a single public package list. Changes are versioned through API-oriented workflows so that operational state can be compared with intended state. Monitoring focuses on signals that help an engineering team make a decision: health, saturation, request timing, network behaviour and dependency state. The goal is not to expose every possible metric, but to preserve enough context to identify whether a problem belongs to compute, storage, network, delivery or the application itself.
02 / ARCHITECTURE
How the service sits in the request path.
Logical components are deliberately shown as separate stages so routing, policy and failure behaviour can be reasoned about.

The diagram is a logical service path. Exact routing, placement and capacity are selected per workload and service profile.
03 / ENGINEERING
Designed for operational work, not just deployment.
Capacity, observability, networking and lifecycle operations are treated as first-class parts of the service.
Origin shielding
Consolidate cache misses through regional shield paths to reduce connection churn and peak load at origin.
Programmable delivery
Headers, cache keys, routing rules and request policies are versioned as part of the service configuration.
Streaming-aware paths
HLS and DASH delivery patterns can be tuned for object size, segment churn and regional audience distribution.
04 / TECHNICAL PROFILE
Service characteristics.
Exact configuration is finalized during architecture review. Values below describe the normal operating model rather than a public rate card.
| Protocols | HTTP/1.1, HTTP/2, HTTP/3 |
|---|---|
| Addressing | IPv4 / IPv6 Anycast |
| Caching | TTL, cache-key and stale-object policies |
| Purge | API-driven targeted and service-level invalidation |
| Origin | Public or private origin connectivity |
| Telemetry | Regional requests, cache status and response timing |
05 / OPERATIONS
Production changes are deliberate.
BitActive does not treat production infrastructure as a sequence of anonymous self-service transactions. New deployments begin with topology, traffic profile, recovery objective and integration review. That context is then carried into provisioning, monitoring and change management so the operational team knows what the service is intended to do before it needs to respond to an exception.
Hardware and software vendors are selected around technical fit. Depending on the workload, the platform uses current-generation technology from AMD, Intel, NVIDIA, Cisco, Dell Technologies and Supermicro. These references describe the technology ecosystem used in infrastructure design; they are not customer references and do not imply a commercial partnership beyond ordinary technology use.
