All Rights Reserved. §  A popular application service on the Internet §  Based on TCP/IP §  Advantages §  Application deployment simplified – URI §  Interoperable open standards and specifications §  Ease of programmability – scripting §  Global reach and Economy of scale §  Accessed by ubiquitous Browsers and also non-Browsers §  Two major protocols -  HTTP (1988/1999) and WebSocket (2007/2011) The Web

All Rights Reserved. §  A riff on “Ubiquitous Computing” (also “Pervasive”) -  Mark Weisner PARC 1988 §  Its early so there’s different definitions -  similar to early days of Cloud Computing §  M2M has been around for decades. Primarily proprietary embedded systems and typically point-to-point (RPC) §  IoT/IIoT (Industrial IoT) -  Adds Internet connectivity -  Networks of M2M systems connected via IP Now… IoT, IIoT and M2M
    • © 2014 Kaazing Corporation. All Rights Reserved. §  No formal API standards §  Many protocol standards – interoperability low §  No common, wide-reaching frameworks §  No composition possibilities §  Difficult to leverage economies of scale §  Barrier to entry is high for millions of app developers §  Also… we’re in a cloud, mobile, web api world IoT/IIoT – connectivity isn’t sufficient

All Rights Reserved. §  IoT – Internet of Things -  Embedded computing endowed with Internet connectivity §  WoT – Web of Things -  Application and Services layer over IoT §  Apply the benefits of the Web to IoT §  WoT is a uniform interface to access IoT functionality §  Provides the abstraction for control/monitoring §  Accelerates innovation Here’s where the Web comes in IoT WoT Developers!

But Is HTTP the Right Choice? 9 l  Disadvantages of HTTP Request/Response l  Lack of resiliency and robustness l  Enterprise events retrieved by resource intensive polling techniques u  Much bandwidth is wasted u  Information can be delayed l  Composite services brittle and lack transactionality l  Enterprises learned advantages of ESB 10+ years ago l  See failures of CORBA, Sun RPC, etc. l  Clumsy AJAX/Comet workarounds to simulate real-time

WebSocket §  Includes W3C API and IETF Protocol (RFC 6455) -  Event-driven JavaScript API -  Full-duplex communication protocol §  Integrates HTTP addressing -  ws://yourcompany.com/collaboration_svc -  wss://anothercompany.com/marketdata_svc §  Traverses firewalls, proxies, routers securely §  Text and Binary §  Application-level Socket over the Web

History Repeats Itself RPC Asynchronous RPC Messaging Enterprise Web/WoT REST Asynchronous REST Messaging •  Can wait for response •  Tight coupling •  Centralized business processes •  Vertical interaction •  Easy to understand (xact) •  Future response •  Loose coupling •  Independent business processes •  More complexity (xact) Did I mention History repeats itself?...

The Message is the Medium “…terse, self-classified messages, networking overhead isolated to a specialized tier of devices, and publish/subscribe relationships are the only way to fully distill the power of the coming Internet of Things” – Francis daCosta
