-== Web Services Accesses ==
+====== Back to IoT infrastructure concepts ======
-// be careful, if you want to use Web Services to access to ThingSpeak first you must create channels to publish data and get the corresponding keys  //
+==== Main concepts ====
+  * IoT Infrastructure architecture : IoT Devices/Edge/Cloud
+  * IoT are devices using sensors but also actuators to perceive and act in the real physical environment
+  * Edge consists in a set of Gateway and/or local servers that exchange information to/from the IoT Devices from/to the Cloud, sometimes after local data processing
+  * Edge Advantages :
+     * Resilience: data processing doesn't depend on the Internet connection
+  * Edge Disadvantages :
+     * Costs for large-scale IoT system: required local resources are more and more expensive (more gateways, more servers, sometimes local datacenters, technicians for maintenance ...)
+     * See simple costs model depending on the number of clients
+  * Cloud provides web services but also data processing, data storage or even virtual machines
+     * we distinguish three kinds of Cloud Software Infrastructures
+     * IAAS, PAAS, SAAS
+  * SAAS: Software as a service (SaaS)
+  * PAAS: Platform as a service (SaaS)
+  * IAAS: Infrastructure as a service (SaaS)
+  * Cost Model :
+     * Pricing Simulator
+     * [[https://azure.microsoft.com/en-us/pricing/calculator/|Pricing Simulator for Microsoft Azure Cloud]]
+     * Exercice: try to evaluate your own cost model depending on the number of clients (makes and comments all the hypotheses you need).
-  * Dataflow that publishes/displays a changing data in ThingSpeak, using timer
+==== Main commercial platforms ====
-// This example uses a key of the 275 public channel : https://sparks-vm24.i3s.unice.fr/channels/275  //
+Main Companies and their solutions: 10 of the famous platforms available today

+  * IBM WATSON IOT PLATFORM
+  * GOOGLE CLOUD PLATFORM
+  * ORACLE
