Windows Azure Service Bus Application Patterns

Haishi Bai, Abhishek Lal — Tue, 05 Feb 2013 15:49:59 GMT

Service bus is a very capable service provided by Windows Azure. In this episode we'll explore some of the application scenarios of two major service bus offerings – relay and messaging. We'll examine different characteristics of the two services in terms of differences in payloads, topologies, scaling patterns, and many other aspects. The following table is taken from the table we built during the session. We hope this episode can provide you some guidance and ideas when designing your own applications.

	Relay	Queues/Topics
Architecture	Coupled	Decoupled
Main value	Connectivity/location separation	loosely-coupled integration
Communication pattern	request-response, pub/sub	asynchronous, batch, offline, pub/sub, request-response possible
Payload	Ephemeral entities	Durable messages
Latency	Latency <10ms	Latency ~200ms
TTL	TTL < 1min	TTL may be in years
Connection	Concurrent listeners with high rates of connect/disconnect	Listener with long-lived durable connections
Scaling	Scale out to multiple listeners and then multiple relay endpoints	Scale out with more entities and data sharding
Topology	Fixed topology	Variable topology
Applications	Real-time data (telemetry) Distributed systems Event feed Connectivity to legacy systems/databases Live-status monitoring Multi-player games (interactive – Pong)	Durable data (orders) SOA/Service integrations Chat Load-leveling State synchronization (distributed) workflows Multi-player games (turn-based – Poker)
Development	WCF/HTTP	.Net client/REST API
