Iasi code camp 20 april 2013 cloud9
The document provides information about cloud computing and Windows Azure Service Bus. It defines cloud computing and its service models including Infrastructure as a Service, Platform as a Service, and Software as a Service. It then describes key benefits of cloud computing such as improved productivity, cost savings, scalability, speed, and mobility. The document proceeds to explain core features of Windows Azure Service Bus including namespaces, queues, topics, subscriptions, and relays. It discusses messaging scenarios such as temporal decoupling, load leveling, load balancing, and publish/subscribe. It encourages using Windows Azure Service Bus and provides a conclusion about messaging.

The name comes from the use of a cloud-shaped symbol as an abstraction for the complex infrastructure it contains in system diagrams.” - Wikipedia “The practice of using a network of remote servers hosted on the Internet to store, manage, and process data, rather than a local server or a personal computer.” - Oxford American Dictionary

- 12. Service Bus ismessaging infrastructure that sits between applications allowing them to exchange messages in a loosely coupled way for improved scale and resiliency. Service Bus is managed and operated by Microsoft with a 99.9% monthly SLA

- 15. Way up inthe cloudsNamespace = Scoping container for addressing Service Bus resources within your application Queue = Sequential message store that offers First In, First Out (FIFO) message delivery to one or more competing consumers Topic = Sequential message store like a queue, but it supports up to 2000 concurrent and durable subscriptions, which relay message copies to a poll of worker processes. A topic extends the messaging features provided by queues with the addition of publish- subscribe capabilities Relay = Cloud service which provides bi-directional communication. Unlike queues and topics, a relay doesn’t store in-flight messages—it’s not a broker. Instead, it just passes them on to the destination application Subscription = Resembles a virtual queue that receives copies of the messages that were sent to the topic
