Advantages of Publish/SubscribeEvent Driven Programming

• Everything becomes dynamic and easier to change

• Much faster when more than one subscriber

• Simplified Programming

private void sendGetRequest(Dart.Snmp.ManagerSlave slave, object state){ try { GetMessage request = new GetMessage(); request.Community= "public"; request.Version= SnmpVersion.One; request.Variables.Add(state as Variable); ResponseMessage response = slave.GetResponse(request, myAgentAddress); manager1.Marshal(new ResponseMessage[] { response }, "", null); } catch (Exception ex) { manager1.Marshal(ex); }}

Platform 3.0The Connected World

• Mobile – 1.5 Billion Smartphones– 600,000 Mobile Apps

• IoT – Billions of devices

• Social – Billions of users

• APIs – 100 Billion API Calls/Minute

• Devops / PaaS – deliver new software daily

• Cloud – IaaS, PaaS, SaaS, iPaaS, CaaS, BaaS, DaaS -$130 billion and growing fast

Technology is in Rapid Evolution
