TRAFFIC ENGINEERING

Health-aware traffic distribution across origins and fault domains.

Layer 4 and Layer 7 load balancing for services that need controlled failover, origin pools and routing decisions based on health rather than static DNS alone.

01 / CLIENTCONNECT

Traffic or control enters a defined service boundary.

02 / BALANCERDECIDE

Policy and placement are evaluated against current state.

03 / ORIGIN AHEALTHY

The workload is processed by the appropriate infrastructure layer.

04 / ORIGIN BSTANDBY

Telemetry is preserved so the path can be explained operationally.

01 / OPERATING MODEL

Infrastructure decisions stay visible.

BitActive treats load balancing 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 Load Balancing, 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.

01

Health-aware pools

Remove unhealthy endpoints from service based on explicit transport or application checks.

02

Weighted routing

Control the proportion of traffic reaching each origin during migration, capacity expansion or staged deployment.

03

Fault-domain design

Keep region, rack and provider boundaries visible to the routing policy instead of hiding them behind one opaque pool.

04

Observability

Track upstream selection, error rates and timing to distinguish network, origin and application failure modes.

Exact configuration is finalized during architecture review. Values below describe the normal operating model rather than a public rate card.

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.
