Calgary azure dev camp - Service Bus

  1. 1. INTRODUCTION TO AZURE SERVICE BUS Kent WeareTitle> <company / contact info> Microsoft Azure
  2. 2. About Me • Microsoft Integration MVP • Author • Blogger • Speaker • Senior Solutions Architect
  3. 3. Agenda • Introduction to the Microsoft Azure Service Bus • Service Bus Relay • Service Bus Queues and Topics • Demos • Event Hubs
  4. 4. Two Flavours of Service Bus Windows Server Service Bus Azure Service Bus Differences • Cost Models • Message sizes • Scale • Release cadence • Tooling
  5. 5. Introduction to MicrosoftAzure Service Bus Integration Routing Coordination Transformation Content-based routing, document transformation, and process coordination. Service Management Naming, Discovery Monitoring ? Consistent management surface and service observation capabilities Messaging Queuing Pub/Sub Reliable Transfer Reliable, transaction-aware cloud messaging infrastructure for business apps. Connectivity Service Relay Protocol Tunnel Eventing, Push Rich options for interconnecting apps across network boundaries
  6. 6. Service Bus Relay • Service Bus acts as an intermediary, or bridge, between Sender and Receiver • Coupling exists between Sender and Receiver • Not very forgiving • Little or no network configuration is required to support Service Bus • In most scenarios, outbound Firewall ports do not need to be opened • No inbound Firewall/NAT ports required • Existing Firewalls continue to secure Datacenter access • Integrated with WCF Programming Model • Commercially available since Q1 2010
  7. 7. Service Bus Relay Sender Receiver Register endpoint via Outbound Connection
  8. 8. Service Bus Queues • Queue is “durably” hosted in the Azure Cloud • Decouples Sender from Receiver • Is more forgiving than Relay Service • Load Leveling • Disconnected Clients • Messages are sequenced in order • Max Queue size is 5GB • Max Message size is 256KB • Sessions allow you to “string” messages together • APIs include .Net,WCF,REST, AMQP, Node.js, Java… • Commercially available since Q4 2011
  9. 9. Service Bus Queues Sender Receiver
  10. 10. Service Bus Queues – Competing Consumer Sender Receiver Receiver
  11. 11. Service Bus Queue Provisioning demo
  12. 12. Service Bus Queues Hello Service Bus demo
  13. 13. Service Bus Topics • Similar to Service Bus Queues • Pub/Sub Capabilities • SQL92 statements • Currently there is support for up to 2000 subscriptions per topic • Send same message to multiple subscriptions provided rule criteria is met • Can have competing consumers on each subscription • Topic – Queue Forwarding is supported
  14. 14. Service Bus Topics – Multiple Subscribers Sender Receiver 1 Receiver 2 City = Edmonton City = Calgary City = Edmonton
  15. 15. Advanced Capabilities (Queues & Topics) • Correlation • Sessions • Reply-To Queues • Message ID • Transaction support • Both Send and Receive operations can be committed atomically • Message Duplication Detection • Time to Live (TTL) • Scheduling • Forwarding • Receive Modes • PeekLock • Abandon • Complete • Receive and Delete • Dead Letter Queue
  16. 16. Demo Scenario • Deregulated Power Generation company who has energy for sale • Power Generator commitment includes: • Declared: Potential amount of Power available • Dispatched: Actual amount of Power that is being generated • Some small variance is expected • When a generator doesn’t meet their commitment there are penalties $$$ • Plant Managers require visibility via Mobile device
  17. 17. Updating Dashboard Mobile Services SQL Database Service Bus Historian #1 Historian #2 Historian #3 DEVICES Push Notification Out of bounds Notification
  18. 18. Updating Dashboard
  19. 19. Event Hubs • Highly scalable publish-subscribe ingestor • Capable of processing millions of events per second • Transform and store data using real-time analytics providers • Pluggable batching/storage adapters (Stream Analytics)
  20. 20. Summary • Service Bus is an enabler technology • Hybrid Connectivity • Cloud based messaging • IoT ingestion • Pub/Sub • Inexpensive • $0.0528 per million operations (Basic Tier) • Interoperable • AMQP • REST • Vast client library support
