Appliance

PubSub+ Event Broker: Appliance

A turnkey appliance that implements message processing directly in purpose-built hardware. Compared with software brokers on general-purpose servers, it delivers lower and more predictable latency — suited to trading, order processing and other workloads where delay or message loss translates directly into cost.

Why the appliance

Consistent low latency from purpose-built hardware
High connection counts and throughput in a single unit
Redundant pairing for continuous operation
Same APIs as the software broker and cloud service, so it joins the same Event Mesh

Capabilities

Capabilities and what they deliver

Capability	What it is	Benefits
Unified platform and high performance	High-performance, low-latency unified messaging middleware • Reliable: up to 28.4 million messages per second (average latency ~18㎲ at 1M msg/sec) • Guaranteed: up to 6.45 million messages per second (average latency ~75㎲ at 140K msg/sec)	• No separate software stack per messaging use case • Replaces 10–20 software-based message brokers (MQ) • A single, consistent architecture
Connection Server	Web messaging • 200,000 concurrent client connections • Rich messaging features and APIs speed up development • Supports a modern web architecture	• Fewer web/WAS servers and lower load on them • Better real-time delivery performance and service quality
Real-time backup between DR sites	WAN optimisation • Compression, TCP optimisation and intelligent routing cut network load between remote data centres • Up to 80% compression, accelerated in hardware • Real-time replication; DR site live within 20 seconds	• Optimised remote links without a separate WAN accelerator • Lower network load on remote connections • Enables real-time DR or active-active data centres
Virtualisation	Independent virtual groups (Message VPN) • Up to 500 virtual instances on a single appliance, with no additional virtualisation software • Domains do not affect one another’s performance	• Clean separation by business unit or workload
Resilience	Slow consumer handling (patented) • During data surges or downstream failures, PubSub+ absorbs the shock so other connected applications are unaffected	• Acts as a shock absorber for overall system stability
